606. THE CHANGES OF THORACOSCOPIC OR LAPAROSCOPIC APPROACH FOR SPONTANEOUS ESOPHAGEAL RUPTURE IN JAPAN

Abstract Background The surgical treatment for esophageal rupture includes various approaches such as thoracotomy, laparotomy, thoracoscopy, and laparoscopy. These approaches aim to: Suture the perforation site, sealing it with omentum. or esophageal resection and reconstruction. Cleanse and drain the mediastinum or thoracic cavity. Adding gastrostomy or intestinal as needed. Many reports showed the usefulness of minimally invasive surgeries. In this study, we added our cases and discussed the surgical techniques and outcomes. Method I searched for reported cases in PubMed and the Journal of Health Care and Society and supplemented them with my experimental cases for analysis. All reports published between 2001 and the end of 2022 were included in this study. Results From 2001 to 2022, there have been 15 reports (16 cases) of idiopathic esophageal rupture using arthroscopic techniques, including our cases, 14 cases in men and 3 cases in women. The ages of the patients ranged from 39 to 78 years (mean 61 years, median 61 years), and the rupture sites were the lower esophagus in 15 cases (88%) and the middle part in 2 cases (12%). The time from onset of symptoms to surgery ranged from 4 to 77 hours. The approach method was thoracoscopy in 7 cases (41%), laparoscopy in 8 cases (47%), and a combination of thoracoscopic and laparoscopy in 2 cases (12%). Complications of Clavien-Dindo classification IIIa or higher were observed in 3 patients (18%). There were two cases each of thoracoscopic and laparoscopic complications in which complications were observed. The time from arthroscopic surgery to discharge was 12-120 days (mean 36.7 days, median 30.5 days). For cases with a thoracoscopic approach, the period from surgery to discharge is 23-120 days (average 50.1 days, median 39 days), and for cases with a laparoscopic approach, the period from surgery to discharge is 12-82 days (average 30 days). days, median 21 days). Discussion Spontaneous esophageal rupture develops various disease patterns such as mediastinum limited type with mild symptoms and intrathoracic rupture type. There are various treatment approaches, including conservative therapy, endoscopic closure, and surgery. The laparoscopic approach seemed to reduce the length of hospital stays. Conclusion The surgical approach for spontaneous esophageal rupture has been changed from thoracotomy to laparoscopic surgery. The trans hiatal procedure will increase among laparoscopic surgery. Spontaneous esophageal rupture is a remarkably highly invasive disease, and we thought that a less invasive and simpler treatment would be desirable.

Rupture of a calcified right ventricle to pulmonary artery homograft by balloon dilation– emergency rescue by venus P-Valve

BackgroundPercutaneous pulmonary valve implantation (PPVI) is a recognized alternative treatment to surgery for patients with dysfunctional right ventricular outflow tracts. Patient selection is essential to avoid serious complications from attempted treatment, such as rupture or dissection, especially of the calcified outflow tracts. We describe a case with an unexpected rupture of a calcified homograft valve and main pulmonary artery, which was treated successfully by emergency implantation of a self-expanding Venus P-Valve (Venus MedTech, Hangzhou, China) without the need for pre-stenting with a covered stent.Case detailsA 13-year-old boy had two previous operations of tetralogy of Fallot, one a total repair and the other a homograft valved conduit for pulmonary regurgitation. He presented with dyspnea and severe right ventricular outflow tract obstruction (RVOTO) and had a calcified outflow tract and main pulmonary artery. In the catheter laboratory, a non-compliant balloon dilation resulted in a contained rupture of the conduit. The patient remained hemodynamically stable, and the rupture was treated with a self-expandable Venus P-Valve without the need for a covered stent combined with a balloon-expandable valve or a further surgical procedure.DiscussionPreprocedural evaluation with an inflating balloon is necessary to examine tissue compliance and determine suitability for PPVI. However, this condition is accompanied by a risk of conduit rupture. Risk factors of this complication are calcification and homograft use. These ruptures are mostly controlled with a prophylactic or therapeutic covered stent, with a low rate of requiring surgery. However, there are severe ruptures which lead to hemothorax and death. In the available literature, there was no similar reported case of conduit rupture, which a self-expandable Pulmonary valve stent has managed. It seems that fibrosis and collagen tissue around the heart, formed after open surgeries, can contribute to the control of bleeding in these cases.Conclusion (clinical Learning Point)The suitability of patients for the PPVI procedure should be examined more carefully, specifically patients with homograft and calcification in their conduit. Furthermore, conduit rupture might be manageable with self-expandable artificial pulmonary valves, specifically in previously operated patients, and the applicability of this hypothesis is worth examining in future research.

Comparable efficacy and safety for bicuspid aortic valve stenosis patients undergoing transcatheter aortic valve replacement with balloon-expandable or self-expanding valves using Wei's sizing method.

The present study aimed to investigate whether proper sizing can improve the procedural and clinical outcomes of transcatheter aortic valve replacement (TAVR) with new-generation self-expanding valves (SEVs) and balloon-expandable valves (BEVs) for treating bicuspid aortic stenosis (BAS). We retrospectively evaluated consecutive patients who underwent TAVR with Sapien 3 valves (Edwards Lifesciences, Irvine, CA) or Evolut R/PRO valves (Medtronic, Minneapolis, MN) for severe BAS from 2017 to 2022. The primary endpoints were device success rate and major adverse cardiac and cerebral events (MACCEs), including mortality, non-fatal myocardial infarction or disabling stroke, transcatheter heart valve failure, or clinically relevant valve thrombosis during follow-up. Our team employed a complementary approach of supra-annular sizing in addition to the conventional annular sizing method (Wei's method) to guide the TAVR procedures. We recruited a total of 75 consecutive patients, of whom 43 (57%) were treated with BEVs from October 2017 to June 2021, and 32 (43%) were treated with SEVs from July 2021 to December 2022. Device success was similar between the BEV and SEV groups (93% vs. 94%; p > 0.99), and no cases of annular rupture occurred in either group. Similar rates of moderate-to-severe paravalvular leak were observed in the BEV and SEV groups (5% vs. 6%, p > 0.99). At a median follow-up of 464 days, the MACCE rates were comparable between the two groups. In multivariate analysis, the presence of previous percutaneous coronary interventions (hazard ratio: 5.43; p = 0.039) and New York Heart Association functional class III/IV heart failure at 30 days of follow-up after TAVR (hazard ratio: 9.90; p = 0.037) were independently associated with long-term MACCEs. Our results demonstrated comparable efficacy and safety for BAS patients undergoing TAVR using either BEVs or SEVs when using Wei's sizing method.

Variceal bleeding following treatment with atezolizumab plus bevacizumab in two patients with unresectable hepatocellular carcinoma.

Bleeding-related adverse events may occur due to anti-vascular endothelial growth factors. Here, we report two cases of variceal rupture during atezolizumab plus bevacizumab (ATZ/BV) treatment for unresectable hepatocellular carcinoma (u-HCC).Case 1 involved a man in his 60s with alcoholic liver cirrhosis (LC) and u-HCC. Seventy-four days after ATZ/BV administration, the patient was admitted for hematemesis. Upper esophagogastroduodenoscopy (EGD) revealed worsening of the esophageal varices (EVs) to F2 grade with active bleeding. Endoscopic variceal ligation successfully achieved hemostasis.Case 2 involved a man in his 70s with alcoholic LC and u-HCC. The patient was admitted with hematemesis 114days after ATZ/BV administration. During EGD, the EVs deteriorated to F3 grade, although hemostasis had already been achieved. The evaluation was discontinued during the observation stage because of the worsening hepatic reserve.Neither patient had EVs warranting prophylactic treatment before ATZ/BV administration, showed a partial tumor response, or had portal vein tumor thrombus. Both patients demonstrated increased total diameters of the collateral veins and splenic volume compared to those before treatment. These findings suggest that ATZ/BV treatment may increase portal pressure. In conclusion, the administration of ATZ/BV to patients with LC and u-HCC necessitates careful management of EVs aggravation and rupture.

Acute splenic pathology on CT in patients with babesiosis.

To better understand the occurrence of splenic disease as a potential manifestation of babesiosis by retrospectively estimating the frequency of acute splenic injury on abdominal and pelvic CT in a cohort of patients with active babesia infection. In a search of our single institution, suburban teaching community hospital database, 57 patients were found to have positive babesia infection between the years 2021-2023. 29 of these patients underwent abdominal and pelvic CT (22 with and 7 without intravenous contrast), and 3 underwent abdominal ultrasound without any CT. The imaging was reviewed for the presence or absence of splenic abnormalities, and for follow-up imaging. Parasitemia levels at the time of imaging were also reviewed; parasitemia levels < 4% are associated with mild to moderate disease, whereas parasitemia levels > 4% are associated with severe disease. 21/32 (66%) patients who underwent any type of abdominal imaging (ultrasound, MRI, and CT) had splenomegaly. Of the 22 patients who had IV contrast-enhanced CT scans, 6 were found to have splenic infarction (27%). One of these 22 patients had multiple rounded non-peripheral hypoenhancing foci on both CT and MRI which did not meet criteria for infarction, in association with splenomegaly, and which resolved after treatment. 0/6 patients in the splenic infarction group had parasitemia levels greater than 4%, while 4 of the 16 patients (4/16) without infarction had parasitemia levels of greater than 4%. Our study showed that splenic disease in patients with babesiosis mostly took the form of splenomegaly, and in a substantial minority of patients as splenic infarction. There were no cases of splenic rupture and perisplenic hematoma in our case series, likely reflecting a limitation of the relatively small study size. Concordant with prior studies, we found no identifiable association between parasitemia levels and the presence of splenic infarction.

Cranio-Maxillo-Facial Reconstruction with Polyetheretherketone Patient-Specific Implants: Aesthetic and Functional Outcomes.

Reconstructing cranio-maxillo-facial defects presents significant challenges. This study evaluates the results of polyetheretherketone patient-specific implants (PEEK PSIs) in primary and secondary cranio-maxillo-facial reconstructions, with a focus on aesthetic and functional outcomes and long-term complications. From October 2009 to February 2023, 45 patients underwent cranio-maxillo-facial reconstructions with PSIs. Patients aged 18 years or older, with a minimum follow-up period of 12 months, were included. The morpho-functional outcome was evaluated through a modified Katsuragy Scale, the Visual Analogue Scale (VAS) for pain, and four FACE-Q|Aesthetics© scales. In total, 44 PSIs were placed in 37 patients (51.3% males; mean age 45.1 years). The main cause of the defect was the resection of a tumor (55.4%). Mean follow-up was 78.6 months. Clinical evaluations showed an improvement in the postoperative period both in patient's and surgeon's scores (p: 0.01 and p: 0.002, respectively). Subgroup analysis confirmed a significant improvement in patients undergoing cranioplasty (p = 0.02) and mandible reconstruction (p = 0.03). No cases of prosthesis dislocation, rupture, or long-term infection were recorded. PEEK PSIs offer significant advantages in craniofacial reconstructions. Despite challenges in predicting soft tissue adaptation, overall patient satisfaction was high with no long-term complications. Future improvements should focus on predicting and enhancing soft tissue adaptations.

CASE REPORTS: Bilateral anterior lens capsule ruptures in Alport syndrome: case series and literature review

We present 3 cases of bilateral anterior lens capsule rupture, all leading to a subsequent diagnosis of Alport syndrome. Clinicians should be alert to the ocular and systemic features of Alport syndrome, especially when presented with a spontaneous rupture of the anterior lens capsule in young males. Ophthalmologists are often the first contact for patients with Alport syndrome, and a sound knowledge of the associated features will enable timely referral to other members of a multidisciplinary team required to treat such patients. Diagnosis and subsequent testing of affected families further aids in genetic counseling and early, comprehensive treatment.

Splenic vein rupture in pregnancy: A case report and systematic review of the literature.

Splenic vein aneurysm (SVA) rupture is a rare clinical entity, with few case reports detailing its occurrence during pregnancy. We describe a case of a SVA rupture and present a systematic review of the literature in relation to splenic vein rupture, with or without aneurysm. Our case was of a 30-year-old woman, Para 4 at 37 weeks' gestation who presented with significant abdominal pain and subsequent maternal collapse. Massive intra-abdominal hemorrhage was identified, with splenic vessel rupture suspected. A splenectomy and partial pancreatectomy were performed along with massive blood product transfusion. There was both maternal and fetal survival with no long-term sequelae at follow-up. Histological examination of the spleen and its vessels noted a SVA rupture. In a subsequent systematic review of the literature, we identified 10 cases of splenic vein rupture with only two previously documented cases of SVA rupture in pregnancy. Maternal and fetal survival has only been reported in two cases of splenic vein rupture, with ours being a third.

Arthroscopic Total Trapeziectomy for Thumb Carpometacarpal Arthrosis.

The purpose of this individual cohort study is to demonstrate safety and efficacy in removing the trapezium through minimally invasive arthroscopy. A prospective case series was performed on all arthroscopic total trapeziectomy procedures for thumb basal joint arthrosis between 2018 and 2022. Patients were followed for up to 1 year. All patients received an examination at each visit to include pain, range of motion, strength, and metacarpal height. Complications, concomitant procedures, and revision procedures were recorded as well. A total of 49 arthroscopic trapeziectomy procedures were recorded for 46 patients. The average preoperative visual analog pain scale score was 8.8 out of 10, and the postoperative score was 1 out of 10. All patients had a resolution of the carpometacarpal grind test postoperatively. The average preoperative key pinch, 3-point chuck, and grip strength were 9.8 lbs/in2, 7.8 lbs/in2, and 45 lbs/in2, respectively. Final 6-month postoperative key pinch, 3-point chuck, and grip strength were 11.0 lbs/in2, 9.8 lbs/in2, and 49.2 lbs/in2, respectively. Metacarpal height subsided on average 50%. We report one revision and no cases of radial sensory neuritis or flexor tendon rupture. Arthroscopic total trapeziectomy appears to be a safe and effective treatment for end-stage arthrosis of the thumb basal joint. 2b Therapeutic; Individual Cohort Study.

Peroneus brevis split rupture is underreported on magnetic resonance imaging of the ankle in patients with chronic lateral ankle pain

IntroductionPeroneus brevis split rupture poses a diagnostic challenge, often requiring magnetic resonance imaging (MRI), yet splits are missed in initial radiological reports. However, the frequency of reported peroneus brevis split rupture in clinical MRI examinations is unknown. AimThis study aimed to investigate underreporting frequency of peroneus brevis split rupture in patients with lateral ankle pain. MethodsWe re-evaluated 143 consecutive MRI examinations of the ankle joint, conducted in 2021 in our region, for patients experiencing ankle pain persisting for more than 8 months. Two musculoskeletal radiologists, with 12 and 8 years of experience respectively, assessed the presence of peroneus brevis split rupture. Patients with recent ankle trauma, fractures, postoperative changes, or MRI artifacts were excluded. The radiologists evaluated each MRI for incomplete or complete peroneus brevis split rupture. The consensus between the raters was used as the reference standard. Additionally, raters reviewed the original clinical radiological reports to determine if the presence of peroneus brevis split rupture was noted. Agreement between raters' assessments, consensus, and initial reports was evaluated using Gwet’s AC1 coefficients. ResultsInitial radiological reports indicated 23 cases (52.3 %) of peroneus brevis split rupture, meaning 21 cases (47.7 %) were underreported. The Gwet’s AC1 coefficients showed that the agreement between raters and initial reports was 0.401 (standard error 0.070), 95 % CI (0.261, 0.541), p<.001, while the agreement between raters in the study was 0.716 (standard error 0.082), 95 % CI (0.551, 0.881), p<.001. ConclusionPeroneus brevis split rupture is underreported on MRI scans of patients with lateral ankle pain.

Applicability of combined high-frequency and contrast-enhanced ultrasound in finger extensor tendon injuries: three case reports

BackgroundBy combining high-frequency and contrast-enhanced ultrasound (CEUS), the position of the severed end of a finger extensor tendon injury and the injury classification can be determined as part of a comprehensive preoperative evaluation in clinical practice. However, there have been no reports of high-frequency ultrasound combined with CEUS for the preoperative diagnosis of human finger extensor tendon injury.Cases presentationOne case of complete rupture of the extensor tendon was diagnosed by ultrasound, which was completely consistent with the surgery; one case of incomplete rupture was ultimately confirmed clinically; and one case of distal phalangeal bone base avulsion fracture with tendon contusion and missed diagnosis on the first radiographic examination was confirmed by follow-up radiographic examination.ConclusionsDifferent types of finger extensor tendon injuries exhibit distinctive contrast-enhanced ultrasonography findings. Combined high-frequency and contrast-enhanced ultrasound can accurately locate the position of the severed end of the finger extensor tendon injury before surgery while observing the contrast agent filling area to clarify injury classification, providing a reliable imaging basis for clinical practice and ultimately developing personalized diagnosis and treatment plans for patients to ensure minimal trauma and pain, as well as optimal treatment effects.

Clinical analysis of breast reconstruction with endoscopic-assisted harvesting of latissimus dorsi muscle flap for breast cancer

To investigate the benefits and drawbacks of breast reconstruction with endoscopic-assisted harvesting of the latissimus dorsi muscle flap for breast cancer and treatment experience of postoperative operation-related complications. A retrospective analysis was performed on clinical data of 26 female patients with breast cancer who met the selection criteria between September 2021 and March 2023 aging 48.7 years (range, 26-69 years). All tumors were unilateral, with 17 on the left side and 9 on the right side. The tumor size ranged from 1.0 to 7.0 cm, with an average of 2.7 cm. The pathological staging included T 1 in 11 cases, T 2 in 14 cases, and T 3 in 1 case; N 0 in 10 cases, N 1 in 11 cases, N 2 in 2 cases, and N 3 in 3 cases; no distant metastasis (M 0) occurred when first diagnosed. Among them, 10 cases underwent breast conserving surgery, and 16 cases underwent nipple-sparing mastectomy. All patients underwent breast reconstruction with endoscopic-assisted harvesting of the latissimus dorsi muscle flap. The operation time, incision length, and postoperative drainage volume in 3 days were recorded. Breast-Q "Satisfaction with back" scale was conducted to evaluate patients' satisfaction with back at 6 months after operation. The operation time was 280-480 minutes (mean, 376.7 minutes), the incision length was 10-15 cm (mean, 12.2 cm), the postoperative drainage volume in 3 days was 500-1 600 mL (mean, 930.2 mL). There were 4 cases of postoperative seroma, 1 case of incision rupture, 1 case of paresthesia of the thoracic wall, and 1 case of edema of the ipsilateral upper limb. All patients were followed up 12-30 months (mean, 20.1 months). No latissimus dorsi muscle flap necrosis, latissimus dorsi muscle atrophy, or shoulder joint dysfunction occurred during follow-up; 2 patients had recurrence of lymph nodes in the ipsilateral axilla after operation, but no distant metastasis occurred. Breast-Q score at 6 months after operation was 64-100 (mean, 79.5). The average score was 78.6 (range, 64-100) in patients underwent nipple-sparing mastectomy and 81.0 (range, 78-100) in patients underwent breast conserving surgery. Breast reconstruction with endoscopic-assisted harvesting of the latissimus dorsi muscle flap for breast cancer is proven to be a surgical approach with safety and cosmetic effects with mild postoperative operation-related complications and considerable patient satisfaction.

Transvaginal radiofrequency ablation: a therapeutic option for managing symptomatic uterine fibroids in women with reproductive desires

To evaluate whether transvaginal radiofrequency (RF) ablation of fibroids is a technique that can be offered to women with reproductive desires. Unicentric, prospective, observational study. University Hospital. Twenty-seven individuals who desired to become mothers after undergoing RF ablation for symptomatic fibroids. Transvaginal RF ablation for symptomatic fibroids with a maximum total volume of 145 cm3. The reduction in the size of the fibroids, improvement of symptoms, and reproductive outcomes during the 24 months after the ablation. For patients who achieved pregnancy, we assessed the type of conception, course of gestation, type of delivery, neonatal outcomes, and occurrence of both maternal and fetal complications. A statistically significant reduction in symptoms related to the fibroids 6 months after the ablation was demonstrated through the implementation of the Symptom Severity Scale. No patient required hospitalization after the procedure, and on average from the third day after intervention, they resumed their work activities without the need for analgesics. Among those patients who attempted pregnancy during the 24-month follow-up period, 73.68 % (14/19) achieved motherhood. There were no cases of uterine rupture, premature birth, or intrauterine fetal death. Radiofrequency ablation for fibroids seems to be a promising, safe, and low-complexity alternative that does not appear to interfere with the development of a normal term gestation.

Spontaneous rupture of uterine during pregnancy after laparoscopic myomectomy: A case report

The danger of future uterine rupture is a serious concern for women who become pregnant after uterine leiomyomectomy or adenomyomectomy, despite the fact that these procedures are commonly used to alleviate symptoms like dysmenorrhea or hypermenorrhea and improve fertility. Although it happens very infrequently, uterine rupture is the most dreaded pregnancy complication and is linked to a high rate of maternal and fetal morbidity and mortality. Here, we present a case of spontaneous uterine rupture during the third trimester of pregnancy.

Rupture of an accessory spleen caused by blunt trauma.

The accessory spleen is quite a common abdominal anomaly. However, the traumatic accessory spleen rupture is an extremely rare condition requiring surgical intervention, even laparotomy. 9 cases of traumatic accessory spleen were found published between 1962 and 2022. The study aims to evaluate traumatic accessory spleen rupture cases regarding their causes, clinical course, and possible diagnosis without surgery and treatment. Desk research method using available online databases. Descriptive methods were employed to analyze the collected data. The results are summarized in the Table concerning gender, age, injury details, accessory spleen injury characteristics, treatment, and others such as previous splenectomy or primary spleen involvement in injury or accompanying abdominal injuries. In total, there were 9 cases of traumatic accessory spleen, of which 2 were managed conservatively and the remaining 7 were treated operatively. All the patients survived. One-third of all included patients already had their primary spleen removed, which facilitated the diagnosis of traumatic rupture of an accessory spleen. The proper diagnosis of an accessory spleen rupture was concluded in 2 cases and confirmed in surgery. The recognition of the traumatic rupture of an accessory spleen before surgery is challenging but can be made easier if the patient underwent splenectomy before. The traumatic accessory spleen rupture does not coexist with an injury of a primary spleen.

The role of the pressure in the endotracheal tube cuff in the development of iatrogenic tracheal injuries

Background. The endotracheal tube insertion, which is a veritable patient care procedure, carries risks and possible adverse effects. Such complications vary in severity and range from mild symptoms such as sore throat or cough, which are often considered normal post-intubation events, to severe damage, including damage to the vocal cords, trachea, malacia, and fistula formation. A critical factor influencing the manifestation of these complications is the pressure exerted by the endotracheal tube cuff on the trachea. The purpose was to study the influence of high pressure of the intubation tube cuff on the incidence and severity of complications in an in vivo model. Materials and methods. A total of 12 rabbits were studied and divided into three groups according to target cuff pressure: 30, 50, and 100 cm H2O. Sevoflurane was used to maintain anesthesia, monitoring of vital functions included heart rate, pulse oximetry, capnography, and electrocardiography. Intubation was performed after induction with ketamine and administration of relaxants, and cuff pressure was measured with a mechanical manometer. The duration of pressure exposure was 20 minutes for each group, then the degree of tracheal damage was assessed by autopsy. Results. Increasing pressure generally leads to an increased risk of injury. In the third group (pressure of 100 cm H2O), all subjects had damage to the trachea, in 75 % of cases, it was a complete tracheal rupture. However, the dependence on pressure is not unambiguous for all types of injuries: the frequency of pneumothorax does not correlate directionally with the incidence of iatrogenic injuries and does not increase proportionally to pressure. So, for example, subcutaneous emphysema developed only in a third of cases of tracheal rupture. This emphasizes possible difficulties in timely diagnosis of this type of complications. Conclusions. The work highlights the risks associated with endotracheal intubation and emphasizes the need to maintain recommended practices and individual approach to each case. The most severe damage was observed at a pressure of 100 cm H2O, while at a pressure of 30 cm H2O, a smaller proportion of rabbits showed signs of damage.

PFCL nightmare: Scleral rupture and novel use of gelatin sponge in repair

We report a case of scleral rupture that occurred during perfluorocarbon liquid (PFCL) injection in a case of bullous rhegmatogenous retinal detachment (RD), which was managed uniquely using a gelatin sponge. So far, only two case reports of scleral rupture during PFCL injection have been reported. A 69-year-old gentleman presented with complaints of sudden-onset painless blurring of vision in his right eye and was diagnosed with pseudophakia with total bullous RD. During 23-G vitrectomy, PFCL was injected using a single-bore cannula. During FAE, the globe appeared hypotonous with choroidal folds. Scleral rupture with retinal incarceration was noted in the superotemporal quadrant. This case report illustrates further unique management.

Comparative digital study using four methods of measurements of the tibial distal anatomical axes for determining the anatomical-mechanical angle in dogs with cranial cruciate ligament rupture.

This study evaluates the amplitude of the anatomical-mechanical angle (AMA-angle) using 4 measuring methods of the tibial distal anatomical axes (DAA) previously described, comparing the literature results to determine if there are significant differences in patients with cranial cruciate ligament (CrCL) rupture. This study was comprised of 30 tibiae (29 dogs), including 1 bilateral case. A retrospective study was selected for this research. DAA measurements were performed on all surgically confirmed cases of canine CrCL rupture at Hospital Veterinário de Especialidades Bruselas from 2019 to 2022. Four different published methods (identified by surname of the corresponding author of the original publication) were compared. Tibial measurements were made using Veterinary Preoperative Orthopedic Planning Pro software (https://vpop-pro.com/) on mediolateral radiographic projections obtained from a digital database. The mean (range) in the DAA method conducted by Hulse obtained a AMA-angle of 5.4° (3.3 to 8.1°), 3.0° (0 to 5.8°) for Osmond et al, 3.2° (0.9 to 6°) for Miles, and 5.9° (2.4 to 8.8°) for Tudury. Differences among the means of the AMA-angle of the authors methods were found with a statistical difference (P < .05), except between Osmond and Miles. The mean AMA-angle with the Osmond method concurred with previous study results that determined the magnitude using the same measurement method of DAA in patients with CrCL rupture. The AMA-angle magnitude has been associated with higher sensitivity and specificity for predicting the development of CrCL rupture compared to other anatomical factors evaluated; therefore, future comparisons with different methods of measurement of the DAA between healthy and affected patients are recommended to determine whether any of them can increase the percentage value as a predictive factor for the occurrence of this condition.

Both Hamstring and Quadriceps Tendon Autografts Offer Similar Functional Outcomes After Arthroscopic Anterior Cruciate Ligament Reconstruction in Patients Aged 50 Years or Older

PurposeThe purpose of this study was to compare the outcomes of hamstring tendon (HT) and quadriceps tendon (QT) autografts for anterior cruciate ligament (ACL) reconstruction in patients older than 50 years in terms of patient-reported functional outcomes, graft failure rates, complications, return to sports activity and the preference for sports. MethodsBetween 2010 and 2022, prospectively collected data were obtained from an institutional database. Patients older than 50 years with primary arthroscopic ACL reconstruction using either HT or QT autograft and a minimum of 2 years of follow-up were included. Patients with concomitant meniscus, cartilage and MCL injury were also included. Patients undergoing a revision ACL reconstruction or undergoing a primary ACL reconstruction using a graft other than HT or QT autograft, and patients with a contralateral knee injury or ipsilateral osteoarthritis (Ahlback stage 2 or higher) were excluded. Patients were evaluated for pre-injury and 2-year follow-up Lysholm knee score, Tegner activity level, Visual Analog Scale (VAS) for pain, graft failure, quadriceps tendon rupture, and return to sport. Mann-Whitney test was used for unpaired samples, whereas the Friedman test was used for analyzing variables over time. The chi-square statistic test was used to determine differences in categorical data between groups ResultsThe number of patients in the QT and HT groups was 85 and 143 respectively. The mean age was 54.4 [50-65] and 56.4 [50-65] for the QT and HT groups respectively, 49% and 51% were males in the QT and HT groups respectively. The two groups did not differ significantly in terms of age, gender, time from injury to surgery and concomitant injuries. No significant differences were found in the pre-injury patient-reported outcome scores (PROMs) as Lysholm, Tegner activity level and VAS for pain between the two groups (p>0.05). At the 2-year follow-up, Lysholm knee score, Tegner activity level and VAS for pain improved to pre-injury level and no significant difference was noted between pre-injury and 2-year follow-up functional scores between the two groups (p>0.05).Furthermore, at the 2-year follow-up, Lysholm score, and VAS didn't show significant differences between QT and HT groups. (p=.390; p= .131). Similarly, no differences have been reported in Tegner activity level scores between HT and QT groups at 2 years of follow-up. No significant differences in terms of minimal clinically important difference (MCID) have been detected between the two groups for Lysholm and Tegner activity scores (p = 0.410 and p = 0.420 for Lysholm score and Tegner activity level score respectively).The two groups did not differ in terms of patient’s percentage of sports participation at baseline, and 2 years of follow-up (p>0.05). A significant decrease (p=0.01) in skiing/snowboarding was reported in the HT group at a 2-year follow-up compared to baseline [116 (81%) vs 98 (69%)]. No case of graft failures and quadriceps tendon rupture was reported in either of the groups. ConclusionArthroscopic ACL reconstruction by using HT or QT autograft in athletically active older than 50 years patients provide satisfactory patient-reported functional outcomes and allows recovery of the pre-injury level of activity.

UTERINE RUPTURE IN A HEALTHY UTERUS ASSOCIATED WITH A RETROPLACENTAL HEMATOMA, REPORT OF A CASE AND REVIEW OF THE LITERATURE

Uterine rupture is a complication of childbirth, its relatively rare but its actual frequency is relative to degree of development of the health system of the country where it occurs. The vital prognosis of the mother and that of the fetus are most often at stake, as well as the subsequent fertility of the patient. Its frequency is increased for scarred uteri and increasingly rare for healthy uterus. Through this work, we present an atypical case of uterine rupture occurring in a non-scarred uterus in a context of eclampsia complicating severe preeclampsia in a 31-year-old patient diagnosed intraoperatively. We discuss through this case and the review of literature, the interest of keeping in mind that this complication can threaten any childbirth even when the diagnosis of other complication seems more conclusive the case of a retroplacental hematoma in our case. The clinical warning signs, the risk factors, the diagnostic methodology are crucial to the therapeutic management of this entity.
