Ultrasound-Guided Fibrin Glue Injection for Treatment of Iatrogenic Femoral Pseudoaneurysms.

Introduction:Arterial pseudoaneurysms (PSAs) are the most common access site complication following transarterial catheter intervention. Ultrasound-guided injection of thrombogenic substances into perfused arterial PSAs followed by compression therapy is a well-established and less invasive treatment option than surgical repair. Different agents are available to induce thrombosis including thrombin and a fibrin-based tissue glue, which is used as first-line treatment at our institution. This paper deals with our experience using ultrasound-guided fibrin glue injection (UGFI).Materials and Methods:Retrospective data analysis: all patients (55) treated for iatrogenic femoral PSA following digital subtraction angiography of the lower extremities between January 1, 2010, and December 31, 2018, were included. Data on epidemiology, PSA location and size, vascular risk factors, fibrin glue injection (fibrin glue volume), primary success rate of UFGI, and complications related to the treatment were analyzed.Results:A total of 55 consecutive femoral iatrogenic PSAs were treated during the defined period and 32 (58.2%) of the patients were female. Imaging was performed using ultrasound in all cases. The most common PSA location (80.0%) was the common femoral artery, mean PSA size (± SD) was 2.7 ± 1.2 cm, and neck length was 1.6 ± 1.0 cm. The dose (mean ± SD) of fibrin glue was 2.6 mL (± 1.0; maximum: 6 mL). Primary UGFI success rate was 87.3% and conversion rate to open surgery was 12.7%. Two (4%) patients required embolectomy for peripheral embolization after UGFI.Conclusion:Early results achieved with UGFI for treatment of iatrogenic femoral PSA are promising. In our cohort, UGFI was a safe and effective first-line alternative to traditional open surgery, which then was unnecessary in the vast majority of PSA cases. Further prospective studies for comparison of ultrasound-guided techniques should be encouraged.

Comparative study of external dacrocystorhinostomy with silicone tube intubation with endoscopic endonasal dacrocystorhinostomy in patients with nasolacrimal duct obstruction

To compare the outcome following external dacrocystorhinostomy with silicon tube intubation with endoscopic endonasal dacrocystorhinostomy in patients with nasolacrimal duct obstruction. A prospective randomized comparative study conducted for 4years 6months in a teaching hospital with 26 cases of external dacrocystorhinostomy with silicon tube intubation and 15cases of endonasal dacrocystorhinostomy with a regular follow-up over 3years.Data regarding outcome and complications were analyzed and compared using chi-square test. Total of 41 patients was included in the study, 22 were females and 19 were males. The mean age for external dacrocystorhinostomy with silicon tube intubation and endoscopic dacrocystorhinostomy was 36.69 years and 39.33years respectively. Epiphora was the commonest presenting symptom (92.3%). Lid edema in postoperative period (3.8%) was the most common complication noted in external dacrocystorhinostomy with silicon tube intubation and bleeding, synechiae formation in endoscopic dacrocystorhinostomy (4.9%).The primary success rate was 100% with external dacrocystorhinostomy with silicon tube intubation, although 5.6% of patients had complications which were treatable and comparable to endoscopic dacrocystorhinostomy which was 90% (P value 0.0477 respectively) with two patients requiring revision procedure with successful outcome over follow-up. The outcome of both external dacryocystorhinostomy with silicon tube intubation and endonasal dacrocystorhinostomy were comparable, although complications were high in endonasal dacrocystorhinostomy (46.8%) with two requiring revision procedure due to failure and results were statistically significant. Therefore external dacrocystorhinostomy with silicon tube intubation can be considered as a primary procedure in patients with epiphora for better success rates and improvement in quality of life in pediatric case.

Outcomes of Endovascular Aneurysm Repair Using the Anaconda Stent-Graft

Purpose: To report outcomes of elective endovascular aneurysm repair (EVAR) using the Anaconda stent-graft in a tertiary vascular center. Materials and Methods: A retrospective study was conducted of 271 patients (mean age 71.5 years; 260 men) who underwent elective EVAR for abdominal aortic aneurysm using the Anaconda stent-graft from January 2006 to January 2017. Median aneurysm diameter was 58 mm (range 50–90). All patients were anatomically suitable for EVAR according to the 2003 version of the instructions for use. Follow-up included computed tomography angiography at 1, 6, and 12 months and yearly thereafter for the first 4 years and then every 2 years. Primary outcomes included technical success and 30-day aneurysm-related mortality and complications; secondary outcomes were overall and aneurysm-related mortality and aneurysm-related morbidity in follow-up. Results: The Anaconda stent-graft was implanted successfully in all patients. Primary and secondary technical success rates were 99.6% and 100%, respectively. Three patients (1.1%) died within 30 days of causes unrelated to the aneurysm, while 15 patients (5.5%) suffered perioperative complications. Median follow-up was 72 months (range 14–141). The overall type I endoleak rate was 4.7% (11 proximal, 2 distal). Late aneurysm-related complications were observed in 48 patients (17.3%); aneurysm-related mortality was 1.4% (n=4). Non-aneurysm-related mortality was 21.0% (n=57). Freedom from reintervention was 95.2% at 1 year, 98% at 2 years, and 90% at 6 years. There was no significant difference in the overall limb graft occlusion rate between the second- and third-generation devices. Conclusion: Results in our cohort study demonstrate that the Anaconda stent-graft has satisfactory early and late results with low aneurysm-related mortality.

Lymphangiography with or without Embolization for the Treatment of Postoperative Chylous Ascites

Lymphatic interventions have recently been increasingly used for treating lymphatic leak of the abdomen and pelvis. This retrospective case study series and systematic review evaluated the efficacy and safety of lymphatic interventions for the treatment of postoperative lymphatic leak of the abdomen and pelvis. A total of 15 consecutive patients with postoperative lymphatic leak of the abdomen and pelvis treated with lymphatic interventions (i.e., diagnostic intranodal or pedal lymphangiography [LAG], i.e., potentially therapeutic or diagnostic LAG with intention to treat through embolization) at our institution were reviewed. The data of 72 patients from 13 relevant articles identified through a literature search of the MEDLINE/PubMed, EMBASE, and Cochrane databases were extracted. The data of 87 patients (mean age, 59 [range, 24-84] years) were pooled. The technical success rate of LAG (intranodal approach, 78.2% [68/87]; pedal approach, 21.8% [19/87]) was 97.7% (85/87; 95% confidence interval [CI], 91.5-99.9%). Of the 85 patients in whom technical success of LAG was achieved, data on clinical success were available for 47 patients (55.3%). The clinical success rate of LAG was 68.1% (32/47; 95% CI, 53.8-79.7%). Of the 85 patients in whom technical success of LAG was achieved, 38 (44.7%) underwent embolization. The technical success rate of embolization was 97.4% (37/38; 95% CI, 85.3-99.9%). The clinical success rate of embolization was 70.3% (26/37; 95% CI, 54.1-82.6%). Major complications did not occur. The overall primary and secondary clinical success rates were 65.5% (57/87; 95% CI, 55.0-74.7%) and 78.2% (68/87; 95% CI, 68.3-85.6%), respectively. Lymphatic interventions are safe and relatively effective adjunct to conservative therapy, with the primary and secondary clinical success rate of 65.5% and 78.2%, for postoperative lymphatic leak of the abdomen and pelvis.

Early Hepatocellular Carcinoma Treated by Radiofrequency Ablation—Mid- and Long-Term Outcomes

Radiofrequency ablation (RFA) is a standard treatment for small inoperable hepatocellular carcinoma (HCC). Studies on mid- and long-term outcome of RFA as first-line therapy for HCC from India are limited. We evaluated consecutive HCC patients who underwent RFA as primary treatment modality at our institute between July 2009 and April 2016. The median follow-up period was 26 months, range 1-84 months. We evaluated post-RFA tumor response, disease-free survival (DFS), overall survival (OS), and local tumor progression (LTP). Prognostic factors were also analyzed. In 147 patients (male:female=121:26; mean age, 59.2 years), 209 RFA sessions were done for 228 lesions (mean size of 21.5±8.3mm, range 10-50mm). Primary success rate was 94.2%. The estimated cumulative proportion survival at 1, 3, and 5 years was 90.2%, 63.8%, and 60.2%, respectively. The cumulative incidence of LTP estimated at 1, 3, and 5 years was 13.1%, 19.7%, and 20.1%, respectively. The mean estimate of LTP-free survival was 53.6 months (95% confidence interval: 0.49-0.58) which is 58.2 months in <3cm lesions and 20.4 months in >3cm lesions (P<0.01). There was no significant difference in LTP rates between lesions in perivascular versus nonperivascular location (P= 0.71) and surface versus parenchymal lesions (P= 0.66). The mean DFS was 30.3 months (95% CI: 25.6-35.0). For OS, age and Child-Turcotte-Pugh class B were significant factors while for LTP, tumor size >3cm was significant. Higher baseline alpha-fetoprotein level and LTP were poor predictors for DFS. Complication rate per RFA session was 7/209 (3.3%). RFA is a safe and effective curative modality for first-line treatment of HCC<3cm.

Clinical Results of Distal Embolization in Grade V Splenic Injury: Four-Year Experience from a Single Regional Trauma Center

PurposeTo evaluate the benefits and risks of splenic artery embolization (SAE) in patients with American Association for the Surgery of Trauma (AAST) grade V blunt spleen injury (BSI) Materials and MethodsMedical records of 88 patients treated with SAE between April 2013 and May 2017 at a regional trauma care center were reviewed retrospectively. The BSI grade according to the AAST spleen injury scale (revised version 2018) was determined by using computed tomography (CT) images. A total of 42 patients (46.6%) had AAST grade V injury and were included in the analysis. Patient demographics, angiographic findings, embolization techniques, and technical and clinical outcomes, including splenic salvage rate and procedure-related complications, were examined. ResultsSAE was performed within 2 hours after admission for 78.5% of the patients. All patients underwent selective distal embolization (n = 42). Primary clinical success rate was 80.9% (n = 34), and secondary clinical success rate was 88.1% (n = 37). The clinical failure group consisted of 5 patients. Four patients underwent splenectomy, and 1 patient died due to acute respiratory distress syndrome after embolization. The splenic salvage rate was 85.7% (n = 36). No patient had sepsis at follow-up (median, 247.0 days; interquartile range, 92.0–688.0). Clinical success rates (P = .356) and spleen salvage rates (P = .197) of patients who were hemodynamically stable (n = 19) showed no significant differences from those who were unstable (n = 23). ConclusionsDistal embolization of grade V BSI is a safe and feasible procedure which is effective for successful spleen salvage.

Décollement de rétine rhegmatogène chez l’adulte jeune : caractéristiques cliniques et résultats chirurgicaux

To report the causes, clinical features and surgical outcomes of retinal detachment (RD) in young adults. Retrospective study of 111eyes of 99patients aged between 18 and 40 years, who underwent primary RD surgery between January 2011 and January 2019. All patients underwent either scleral buckling or pars plana vitrectomy. We analyzed the demographic data, characteristics of the RD, primary and final anatomic success rate and best-corrected visual acuity (BCVA) at the conclusion of follow-up. The mean age of the patients was 30.3±6.5years. RD was more frequent in males, with a gender ratio of 1.8. The breaks were atrophic round holes or retinal dialysis in 49(44.2%) cases and were associated with posterior vitreous detachment in 62(55.8%) cases. The main etiologies were high myopia (45.0%) and trauma (9.0%). Retinal reattachment was achieved in 74 (66.5%) eyes overall with a single procedure and in 108 (97.2%) eyes with two or more procedures. The primary success rates were 69.6% (46/66eyes) with scleral buckling and 62.2% (28/45 eyes) with vitrectomy. High myopia was a risk factor for surgical failure (P<0.01). The mean BCVA improved from 0.71±0.64 logMAR to 0.41±0.35 logMAR (P<0.01) CONCLUSION: RD in young adults differs from that in older adults in clinical features and etiology. The main causes are trauma and high myopia. The anatomic outcomes appear less favorable, with a primary reattachment rate of 66.5%. However, the functional prognosis remains satisfactory with an improvement of 3 lines of visual acuity.

Patient reported long-term outcome after endovascular therapy of indirect dural carotid cavernous fistulas.

PurposePatient-reported long-term follow-up after endovascular treatment of indirect carotid cavernous fistulas is important, but rarely addressed in literature. We report on this issue with a special focus on the patient’s view and its impact on the indication evaluation process.MethodsWe retrospectively reviewed the records of all patients (n = 33) with a minimum follow-up interval of at least 36 and up to 166 months after endovascular treatment of an indirect carotid cavernous fistula (Barrow B-D) at our institution (treated from 01/2003 to 06/2015). We determined treatment details including primary therapy success and complication rate and quote the patient’s subjective perception of the long-term treatment success using a standardized interview form.ResultsAs a primary result the fistula was completely occluded in 25/33 cases (76%), while a downgrading was achieved in 8/33 (24%) of the cases. Secondary occlusion was observed in three out of eight patients (38%). In the long-term interview (response rate: 91%, median follow-up interval: 114 months) 87% of the patients reported high satisfaction with the long-term therapy result. Endovascular treatment achieved a sustainable relief from all eye-related symptoms in 89% and from pulsatile tinnitus in 57% of the cases.ConclusionsIn addition to good results in terms of angiographic and clinical cure, endovascular treatment is also perceived as beneficial by most of the patients. This is another important argument in favor of an endovascular treatment.

Long-term outcomes of the Ovation Stent Graft System investigational device exemption trial for endovascular abdominal aortic aneurysm repair

ObjectiveThe objective of this study was to report the 5-year outcomes of the Food and Drug Administration investigational device exemption clinical trial of endovascular aneurysm repair (EVAR) with the Ovation stent graft (Endologix, Irvine, Calif) for elective treatment of abdominal aortic aneurysm (AAA). MethodsThe study comprised 161 patients who underwent EVAR as part of the prospective, international, multicenter pivotal Ovation stent graft trial. The main inclusion criteria were AAA diameter ≥5 cm, proximal neck length ≥7 mm, neck angulation ≤60 degrees, and bilateral iliac fixation length ≥10 mm. The primary end point was a composite outcome of primary clinical success at 5 years. Primary clinical success was defined in accordance with the Society for Vascular Surgery guidelines as successful aneurysm exclusion without aneurysm-related death, type I or type III endoleak, graft infection or thrombosis, aneurysm expansion, aneurysm rupture, graft migration, or conversion to open repair. Secondary end points included freedom from reintervention, all-cause mortality, and aneurysm-related mortality. ResultsPatients were predominantly male (87.6%) and elderly with a mean age of 73 ± 7.7 years; 66 patients (41%) had challenging anatomy and would be considered outside the instructions for use with other stent grafts, 26 (16.2%) had a proximal neck length <10 mm, and 53 (33%) had a minimum access vessel diameter <6 mm. Technical success was 100%. Of 126 surviving patients, 84 (66.7%) completed 5-year follow-up. The 5-year primary clinical success rate was 78%, aneurysm-related mortality was 1% (one patient), and all-cause mortality was 25%. The AAA-related death resulted from AAA post-EVAR rupture at 49 months in a patient who refused treatment for a type IB endoleak. Freedom from type I or type III endoleak was 95.1%. Freedom from secondary interventions was 80.2%. Most of the reinterventions were performed for type II endoleak (24 [63.1%]) or for limb thrombosis or stenosis (7 [18.4%]). There was no graft migration. None of the patients required open conversion. ConclusionsFive-year results from the Ovation pivotal and continued access investigational device exemption trials demonstrate excellent long-term durability of this endograft despite that 41% of patients had anatomy unfit for other stent grafts. There were no migrations or conversions to open repair and 99% freedom from aneurysm-related mortality. These results suggest a less invasive on-label endovascular option for patients with challenging anatomy who may otherwise require hybrid or open repair.

25-years Trends and Risk factors related to Surgical Outcomes of Giant Retinal Tear-Rhegmatogenous Retinal Detachments

To describe the 25-year surgical trends, long-term outcomes and risk factors affecting the outcomes of giant retinal tear-related rhegmatogenous retinal detachments (GRT-RRD). Patients’ demographics, pre-operative characteristics, risk factors, operative procedures and post-operative outcomes were collected and divided into three groups – Group A: 1991 to 2015 (overall); Group B: 1991 to 2005, and Group C: 2006 to 2015. Functional and anatomical successes were monitored over a 5-year period. Multivariate logistic regression analysis was performed to identify the risk factors related to functional and anatomical success.127 eyes of 127 patients were included in the study. At 5th year, 69.4% patients had visual acuity (VA) < logMAR 1.0 with 87.5% primary anatomical success rate. While the functional outcome remained the same between group B and C, there was an increase in the anatomical success from 89.7% to 100%, albeit not statistically significant. Patients with worse presenting VA, 150 degrees or more of giant retina tear, macula-detached status and presence of PVR were associated with VA of> logMAR 1.0 (all p < 0.05). The types of surgery (TPPV vs combined SB/TPPV), number of breaks, lens extraction and additional cryotherapy were not associated with the functional or anatomical success. In conclusion, the GRT-RRD functional and structural outcomes were comparable between 1991–2005 and 2006–2015, albeit a statistically insignificant improvement of anatomical outcome over the past 25 years. Worse presenting VA, 150 degrees or more of giant retinal tear, detached macula and presence of PVR were associated with poorer visual outcome.

Five Year Results of the French EPI-ANA-01 Registry of AnacondaTM Endografts in the Treatment of Infrarenal Abdominal Aortic Aneurysms

A significant decrease in aneurysm related survival is observed at long term follow up after infrarenal endovascular aneurysm repair (EVAR) compared with open repair. Therefore, longer term results with new generation endografts are essential. The aim of this post-approval French multicentre prospective observational study (EPI-ANA-01) was to evaluate the technical success and five year mortality and secondary intervention rates of the third generation AnacondaTM endograft. From June 2012 to October 2013, 176 consecutive unruptured infrarenal abdominal aortic aneurysms were included (160 male patients, mean age 75.3±8.4 years). Survival, freedom from type Ia endoleak, limb events, and re-interventions were estimated using the Kaplan-Meier method. Anatomical and clinical characteristics were compared according to the occurrence of migration, conversion, adverse limb events, endoleak, and sac enlargement. The primary technical and clinical success rates were 98.3% and 94.9%, respectively. A hostile neck was identified in 33.9% of patients and 10.7% were treated outside instructions for use (IFU). An early post-operative (≤30 days) mortality rate of 1.7% was observed. At one and five years, respectively, the overall survival rate was 94.9% and 65.9% (aneurysm related in four patients [2.3%]) and the clinical success rate was 90.9% and 70.6%. Secondary interventions were performed in 35 of 176 patients (19.9%). The overall limb occlusion rate was 7.9% and the aneurysm sac diameter decreased significantly (pre-operative diameter 53.9±8.6mm vs. 42.3±14.7mmat five years; p<.001). Patients treated outside the instructions for use (IFU) had significantly higher rates of migration, surgical conversion, and aneurysm sac expansion (p=.03). The Anaconda endograft provides high technical success and satisfactory five year aneurysm exclusion and clinical success rates. However, implantation outside the IFU should be avoided, as it leads to significantly worse outcomes, and caution over the risk of limb occlusion and distal embolisation should be observed.

Early and mid-term results of endovascular treatment of thoracic aorta diseases: a single-center experience

We conducted an analysis to assess early and mid-term outcomes of patients after thoracic endovascular aortic repair (TEVAR) for type B thoracic aorta dissection, descending thoracic aneurysm, or traumatic aortic transection. From January 2016 through December 2018, twenty-seven patients (23 male, 4 female, mean age of 57 years) affected by type B dissection (n = 13 [48.2%]), thoracic aneurysm (n = 9 [33.3%]), and post-traumatic aortic isthmus rupture (n = 5 [18.5%]) were treated using TEVAR with and without left subclavian artery revascularization. All procedures were performed in a hybrid operating room using general (n = 12) or regional (n = 15) anesthesia. A combined brachial artery and bilateral femoral artery access was used in all patients. To achieve adequate proximal thoracic aorta landing zone length, coverage of the left subclavian artery with proximal endovascular plug occlusion was performed in 17 patients (62.9%); including 4 patients undergoing carotid–subclavian artery bypass before TEVAR stent-graft deployment. Primary procedural success rate was 96.3%; 1 patient had a Type Ib endoleak that was treated by distal stent graft extension. Four adverse outcomes occurred in the immediate postoperative period, including 2 cases of left upper arm acute ischemia (7.4%), ischemic stroke (3.7%), and asymptomatic iliac artery dissection (3.7%). During a mean follow-up of 18 months, no graft-related deaths or endoleak occurred. One patient developed symptomatic subclavian steal syndrome 1 month after operation and underwent a left carotid–subclavian artery bypass with symptom resolution. One patient died 6 months after TEVAR due to neoplasm. Our experience indicates TEVAR is a safe and less invasive alternative to open surgery for a spectrum of thoracic aorta diseases, especially for urgent conditions and in patients with high-risk surgical comorbidities.

Computed Tomography-Guided Radiofrequency Ablation of Osteoid Osteoma in Atypical Sites: Efficacy and Safety in a Large Case Series

Although computed tomography (CT) guided radiofrequency ablation (RFA) is accepted as the gold standard treatment for osteoid osteoma (OO) in extremities, most researchers have omitted OO in critical sites. We aimed to evaluate the efficacy and safety of CT-guided RFA in the management of OO in atypical sites. A prospective interventional study conducted on 34 patients (12 women and 22 men; mean age, 22.3 ± 3.5 years; range, 12-48 years) with OO in atypical sites. All patients were treated with CT-guided RFA. All procedures were performed under general anesthesia using a single straight, rigid RF electrode for 6 minutes at 90°C. All patients were followed up; technical and clinical successes of treatment were evaluated. The severity of pain was assessed on a visual analogue scale (VAS). CT-guided RFA was performed in all patients with 100% technical success and 100% primary clinical success. All patients had complete pain relief and returned to their quality of life without further analgesics within 1 month after the procedure. All procedures were successfully completed without any major complications. The mean preprocedure VAS score dropped to zero by the end of the first week with a highly statistically significant difference (p < 0.001). CT-guided RFA is a safe and effective procedure in the management of OO in atypical sites with 100% primary success rate, 0% long-term recurrence rate, and very low complication rate.

Titrated baclofen for high-risk alcohol consumption: a randomized placebo-controlled trial in out-patients with 1-year follow-up.

AbstractBackground and AimsBaclofen is a promising drug for treating patients with alcohol‐related disorders. Nevertheless, the first randomized clinical trials (mainly with target doses) reported inconsistent efficacy, possibly because of the effective dose widely varying between patients. The Bacloville study aimed to test the efficacy of titrated baclofen for achieving low‐risk alcohol consumption.DesignTwelve‐month multicenter pragmatic double‐blind randomized clinical trial from June 2012 to June 2014.SettingSixty‐two French primary care centers.ParticipantsOut‐patients with high‐risk alcohol consumption (&gt; 40 g/day for women and &gt; 60 g/day for men).Intervention and comparatorPatients were randomly assigned (1 : 1 ratio) to receive titrated baclofen up to 300 mg/day or placebo for 12 months. Switching to open‐label baclofen was allowed in cases of perceived inefficacy.MeasurementsThe primary outcome defined success as no or low‐risk alcohol consumption (≤ 20 g/day for women and ≤ 40 g/day for men) during the last month of the 1‐year follow up, with patients who switched to open‐label baclofen classified as failures.FindingsA total of 320 patients were randomized, 162 to baclofen and 158 to placebo (consumption 129 g/day in both arms). Discontinuation rates were 30 and 34% in the baclofen and placebo arms, respectively, and return rates of the last‐month diaries were 42 and 34%, respectively. Primary success rates were 57 and 36% in the baclofen and placebo arms, respectively [difference: 21 percentage points, 95% confidence interval (CI) = 8–34, P = 0.003]. When switchers were not classified as failures unless they failed, the success rates were 62 versus 55% (difference: 6 percentage points, 95% CI = –7 to 20). Over 12 months, daily consumption differed between both arms (11 g less in the baclofen arm), as did the number of abstinence days (3.3 days more in the baclofen arm). Adverse events were more frequent with baclofen than placebo and were mostly drowsiness, fatigue and insomnia. Serious adverse events occurred in 85 (seven deaths) and 36 (three deaths) patients with baclofen and placebo, respectively.ConclusionsBaclofen was more effective than placebo in reducing alcohol consumption to low‐risk levels. The number of adverse events and more serious adverse events was greater with baclofen than placebo.

Diagnostic Imaging Findings and Endovascular Treatment of Patients Presented with Abdominal Pain Caused by Spontaneous Isolated Superior Mesenteric Artery Dissection

Background: Isolated dissection of visceral artery organs is very infrequently reported and when occurred mostly affected is the superior mesenteric artery (SMA) with abdominal pain as the commonest presenting features in symptomatic patients. Dissection can be detected by ultrasound and CT, but computed tomography angiography (CTA) is the best for demonstration of the true and false lumens of the lesion. Nonetheless, the perfect treatment has not been accepted yet. However, if left untreated, it is a life-threatening condition. Objectives: Our aim is to evaluate diagnostic imaging and endovascular treatment outcome of spontaneous isolated superior mesenteric artery dissection (SISMAD). Based on the angiographic configuration of SMA and location of dissection we will share our experience based on deployment of a bare straight stent, bare tapered stent, overlapping bare stent or coil assisting bare stent. Patients and Methods: Medical data from patients presented with symptomatic superior mesenteric artery dissection (SMAD) and had received endovascular treatment between January 2007 and December 2017 were extracted. Patient demographics, symptoms, diagnostic imaging, endovascular treatment, and follow-up findings were analyzed. Results: Total of 31 patients were included in this study [87.1% (n = 27) male, 12.9% (n = 4) female, and mean age 52.9 ± 8.2 years]. All patients had abdominal pain as the main presenting symptom. The mean length of dissection was (4.79 ± 3.03) cm, mean distance from the aorta to dissection entry was 2.5 ± 1.0cm, mean percentage stenosis was 63.3 ± 12.7%, Sakamoto type IIA was seen in 35.5% (n = 11), and type IIB in 64.5% (n = 20). All of the patients received bare self-expandable stent whereby 90.3% (n = 28) received stent(s) without coil, of which 64.3% (n = 18) received single straight stent, 21.4% (n = 6) received overlapping stent and 14.3% (n = 4) received tapered stent. On the other hand, 9.7% (n = 3) received coil assisting stent. Post-procedure normal blood supply to the distal SMA and relief of symptoms was noted. One hundred percent (n = 31) primary success rate was recorded during mean fasting and follow-up time of 4.9 ± 1.9 days and 15.5 ± 4.8 months, respectively. Conclusion: Endovascular treatment with a bare stent is a safe, effective, and successful treatment for symptomatic SISMAD with satisfactory outcomes. We highly recommend it to be considered as a first-line treatment in severe co-morbidity patients who are unfit for open surgery.

Early Covered Self-Expandable Metal Stent Placement Is Effective for Massive Post-endoscopic Sphincterotomy Bleeding.

Placement of covered self-expandable metallic stent (CSEMS) for post-endoscopic sphincterotomy (ES) bleeding achieves excellent hemostasis results. Although CSEMS placement is typically performed after failure of conventional endoscopic combination therapy, its excellent outcomes may justify earlier placement. We aimed to examine the efficacy of "early" CSEMS placement for massive post-ES bleeding. The medical records of 2750 patients who underwent ES between 2005 and 2019 were reviewed retrospectively, and 61 patients who developed massive post-ES bleeding were enrolled. These patients were divided into those who underwent early CSEMS placement (E-CSEMS group) and those who underwent conventional endoscopic combination therapy (Conventional group). The outcomes of hemostasis procedures were compared between the groups. The primary success rates of endoscopic hemostasis were 100% (21/21) and 98% (39/40) in the E-CSEMS group and Conventional group, respectively, without significant differences (P = 1.000). However, in the E-CSEMS group, re-bleeding was significantly less frequent (5% vs. 31%; P = 0.023), the median hemostasis procedure time was significantly shorter (14min vs. 26min; P < 0.001), and transfusion after initial hemostasis treatment was less commonly required (10% vs. 38%; P = 0.034). Multivariate analyses showed that hemodialysis was associated with a significantly higher re-bleeding rate (P = 0.029), while CSEMS placement was associated with a significantly lower re-bleeding rate (P = 0.039). Early CSEMS placement may be effective for improving the clinical outcomes of massive post-ES bleeding by decreasing re-bleeding and the extent of bleeding.

Rate of Postoperative Autofluorescent Macular Shift with Expanding Gas Bubble Tamponade and No Prone Posture Ambulatory Care in Patients with Macula-Involved Retinal Detachment

Purpose: Chronically distorted vision is an important adverse outcome in patients with otherwise successfully treated macula-involved retinal detachment (RD). Symptomatic distortion is associated with macular vessel shift on fundus autofluorescence (FAF) imaging. Immediate prone posture has to date been the only mechanism adopted to reduce postoperative FAF shift. The aim of this study was to establish the rates of primary anatomical success and (FAF) macular shift in 67 eyes with macula-involved RD and superior breaks treated with vitrectomy, retinopexy, 0.7–1 mL 100% gas tamponade, and no prone posture. Methods: Single-center, retrospective series. Results: Rates of primary anatomical success and fundus autofluorescent imaging macular shift were 89 and 26%, respectively. Conclusion: Vitrectomy with a 0.7–1 mL expanding gas bubble tamponade and no prone posture were associated with an acceptable rate of primary anatomical success. We found the lowest yet reported rate of FAF shift in patients with macula-involved RD. If confirmed, this simple technique modification could improve the visual outcome of RD surgery whilst facilitating postoperative ambulatory care.

Genetic diversity and structure of Ganoderma boninense isolates from oil palm and other plantation crops

Abstract. Purba A, Hayati R, Putri LAP, Chalil D, Afandi D, Syahputra I, Basyuni M. 2020. Genetic diversity and structure of Ganoderma boninense isolates from oil palm and other plantation crops. Biodiversitas 21: 451-456. Oil palm is an economically important plant, which one of the most important sources of vegetable oil in the world. However, oil palm plantation and other crops face the treat basal stem rot (BSR) disease by Ganoderma boninense. A study on genetic diversity and structure of G. boninense is therefore needed in order to formulate improved control strategies for this disease. This work aimed to analyze the genetic diversity and structure of the G. boninense isolates derived from different hosts, 131 oil palm (Elaeis guineensis), six rubber (Hevea brasiliensis), three coconuts (Cocos nucifera), and three lontar palm (Borassus flabellifer). Genetic diversity and population structure of G. boninense isolates were investigated using six SSR markers with GenAlex 6.502 software. Results showed that several microsatellite loci indicated specific primary success rates, such as KT124402, KT124399, and KT124394, depicting high polymorphism content (&gt;75%). This result suggested that these markers were equally effective in determining the polymorphisms of G. boninense isolates. A hierarchical analysis of molecular variance (AMOVA) revealed that genetic diversity mostly found among individuals within a population (88%), then among populations (8%), and within individuals (4%).. Phylogeny analysis showed two clusters of Ganoderma isolates. which was considered variation as dissimilar across with origin. The present study indicated that G. boninense from oil palm was predominantly comprised of a genetically distinct individual.

SURGICAL OUTCOMES OF 25-GAUGE PARS PLANA VITRECTOMY USING AIR AS AN INTERNAL TAMPONADE FOR PRIMARY RHEGMATOGENOUS RETINAL DETACHMENT.

To report surgical outcomes of 25-gauge pars plana vitrectomy using air as an internal tamponade for patients with primary rhegmatogenous retinal detachment (RRD). A retrospective clinical study of 59 eyes of 59 consecutive patients presented with primary RRD at the Beijing Tongren Eye Center in China. From August 2016 to May 2018, medical records of the patients who underwent 25-gauge pars plana vitrectomy with air tamponade for RRD were reviewed. The main outcome measures were primary and final anatomical success (retinal re-attachment) rates, and postoperative complications. Of the 59 patients, aged 54.47 ± 11.81 years, 31 (52.5%) were men. Vitrectomy was performed 3 to 40 (averaged 16.98 ± 10.17) days after the onset of symptoms, and the mean follow-up period was 12.90 ± 5.92 months (ranging 6.07-26.10 months). Forty-two eyes (71.2%) had RRD with retinal breaks in the superior half of the retina, and the mean number of retinal breaks was 1.75 ± 0.94. Three eyes (5.1%) had RRD with giant retinal tears. Of the 59 eyes, 35 (59.3%) had RRD with inferior quadrants involved. Proliferative vitreoretinopathy (PVR) gradings were C1 in 2 (3.4%) eyes and B or below in 57 (96.6%) eyes. The primary and final anatomical success rates were 94.9% (56/59) and 98.3% (58/59), respectively. Of the three eyes which developed re-detachment of the retina, one eye had postoperative progression of PVR and two eyes were RRD associated with macular hole in high myopia. Postoperative complications included 5 eyes (8.5%) with serous choroidal detachment within 3 days after surgery and 4 eyes (6.8%) with macular epiretinal membrane formation 1 to 8 months after surgery. Secondary cataract surgery was performed in 13 of the 53 phakic eyes (24.5%) during follow-up. Small-gauge pars plana vitrectomy with air tamponade may be effective in treating selected cases of relatively simple primary RRD. Additional studies are needed to verify the efficacy of this surgical approach for more complicated cases such as those with giant retinal tears.

Fecal Microbiota Transplantation for Recurrent Clostridium difficile Infection in Patients With Multiple Comorbidities: Long-Term Safety and Efficacy Results From a Tertiary Care Community Hospital.

BackgroundCure rates of Clostridium difficile infection (CDI) with fecal microbiota transplant (FMT) have been promising. However, there is debate regarding success of FMT in patients with comorbidities.MethodsElectronic chart review was done to collect data on patients who underwent FMT from January 2015 to August 2017. Charts were analyzed in November 2018 with a median follow-up of 25.4 months (interquartile range 20 - 31 months).ResultsTwenty patients underwent FMT. The primary success rate at our institution was 90% and overall success rate was 100%. Six patients (43%) had FMT failure (two early and four late).ConclusionsThis case series is a description of our center’s initial experience with FMT for treatment of recurrent CDI. Our high success rate reiterates the efficacy and safety of FMT in this population including patients with comorbidities.
