HELLP syndrome, intracerebral hemorrhage, and hemophagocytic syndrome after cesarean section in a pregnant patient with severe preeclampsia: a case report

BackgroundPregnancy-related intracranial hemorrhage (ICH) is a rare but potentially life-threatening event with complex and varied cause, such as HELLP syndrome and hemophagocytic syndrome.Case presentationA 33-year-old patient underwent a cesarean section with a preliminary diagnosis of "severe preeclampsia and class3 HELLP syndrome ". The patient had poor response to language before surgery, and the catheter drainage fluid was hematuria. Later, the surgeon reported severe bleeding in the operation. Following thromboelastography (TEG) result and postoperative laboratory tests confirmed class1 HELLP syndrome and ICH occurred on the second day after the surgery, and hemophagocytic syndrome was diagnosed during subsequent treatments.ConclusionFor patients with HELLP syndrome, we should pay attention to their coagulation condition. The coagulation tests and platelet counts should be repeated if their clinical presentation changed. Those with neurological alarm signs should receive CT or MRI scan. If a pregnant woman had prolonged hemocytopenia and thrombocytopenia, not only the HELLP but also the hemophagocytic syndrome should be considered.

Abstract No. 56 Comparing Outcomes of Percutaneous Biliary Drainage Catheters in Right versus Left Hepatic Approaches

Determine if there is a difference in complications associated with right or left hepatic percutaneous biliary drain placement in patients with benign or malignant biliary etiology. This retrospective study included patients with benign or malignant biliary stricture and treated with percutaneous biliary drainage at a single institution from 7/28/2004 to 3/30/2021. Three hundred fifty-seven patients met inclusion criteria, seventy-seven on the left and two hundred and eighty on the right, with a mean age of 65.1 years. Complications associated with the initial drain placement or during subsequent intervention were collected and categorized. Perioperative complications included surgery, infection, hemorrhage, and drain failure. Complications during treatment with a percutaneous biliary drain included death, chills, catheter displacement, cholangitis, biliary stones, drain malfunction, fever resolving without treatment, and pericatheter leakage. Complications were also grouped as major or minor. Statistical analyses were performed using logistic regression analysis and P values less than 0.05 were considered significant. Major interventional and treatment complication rates showed no statistical significance between left and right drains. The rate of minor interventional and treatment complications also showed no statistical significance between right and left drains. However, when cholangitis was analyzed individually, right sided hepatobiliary drains demonstrated a statistically significant increase in complication rates. Current literature describes safety of right biliary drain placement when compared with left, despite current equivocal study analyses. This large group analysis describes no statistically significant difference in complications between right and left hepatobiliary drains aside from slightly higher incidence of cholangitis for right sided drains.

Antibiotic impregnation and nanocoating of external ventricular drainage catheters for antibacterial applications: Evaluation of in vitro studies and molecular docking.

The most suitable method to treat hydrocephalus disease is to insert a shunt catheter that drains the cerebral spinal fluid (CSF); however, shunt implantation is often associated with various bacterial infections. In this study, antibiotic-loaded nanospheres were prepared using the solvent evaporation technique and coated on an antibiotic-impregnated shunt surface to promote shunt antibacterial properties. Clindamycin (CDM) and rifampicin (RIF) were in combination loaded in a single nanosphere, whereas trimethoprim (TMP) was loaded individually in triblock copolymers [(d,l-lactide-random-ε-caprolactone)-block-poly(ethylene glycol)-block-(d,l-lactide-random-ε-caprolactone)] (PLEC). The drug-loading content, encapsulation efficiency, yield, size, and zeta potential of the antibiotic-loaded nanospheres were measured. The results showed that the drug-loading content of clindamycin- and rifampicin-loaded nanospheres (CDM/RIF-NPs) was approximately 3% and 8%, respectively, at a drug to polymer ratio of 1:2. In addition, trimethoprim-loaded nanospheres (TMP-NPs) showed nearly 7% drug loading at equal drug and polymer ratios. The amount of drug release was determined before and after the coating of nanospheres on the shunt surface. In addition, in silico molecular docking studies indicated the good chemical interaction of these antibiotics with PLEC, and the results were consistent with those of impregnation studies. Antibacterial tests of coated external ventricular drainage showed antibacterial activity for up to 21 days.

Reintervention Rate After Pigtail Catheter Insertion Compared to Surgical Chest Tubes.

Prior studies suggest similar efficacy between large-bore chest tube (CT) placement and small-bore pigtail catheter (PC) placement for the treatment of pleural space processes. This study examined reintervention rates of CT and PC in patients with pneumothorax, hemothorax, and pleural effusion. This retrospective study examined patients from September 2015 through December 2020. Patients were identified using ICD codes for pneumothorax, hemothorax, or pleural effusion. Use of a pigtail catheter (≤14Fr) or surgical chest tube (≥20Fr) was noted. The primary outcome was overall reintervention rate within 30days of tube insertion. Patients who died with a pleural drainage catheter in place, unrelated to complications from chest tube placement, were excluded. There were 1032 total patients in the study: 706 CT patients and 326 PC patients. The PC group was older with more comorbidities and more likely to have effusion as the indication for pleural drainage. Patients with PC were 2.35 times more likely to have the tube replaced or repositioned (P < .0001), 1.77 times more likely to require any reintervention (P = .001) and 2.09 times more likely to remain in the hospital >14days (P < .0001) compared to patients with CT. PCs have a significantly higher reintervention rate compared to CT for the treatment of pneumothorax, hemothorax, and pleural effusion. Although PC are believed to cause less pain and tissue trauma, they do not necessarily drain the pleural space as well as CT. Decisions on which method of draining the chest should be made on a case-by-case basis.

Extraintestinal Clostridioides difficile Infection (CDI): A Recurrent Battle with Resilient Abdominal Wall Abscess.

Risk factors for extraintestinal CDI include prior hospital stay, prolonged antibiotic therapy, proton pump inhibitor (PPI) use, relative state of immunodeficiency such as malnutrition and diabetes mellitus, previous abdominal surgery especially following perforation and leak of intestinal content.Presentation can be late following surgery with mesh repair (foreign body implantation) for intestinal perforation as they have high risk of colonisation, which later leads to infection.For extraintestinal CDI in the presence of a foreign body, removal is the desired course of action. But it is not always possible given the presence of comorbidities in this population, thus resulting in a prolonged course of antibiotics.

COMPARISON OF THE MODIFIED CT SEVERITY INDEX WITH THE CT SEVERITY INDEX FOR THE ASSESSMENT OF ACUTE PANCREATITIS SEVERITY

Introduction: Acute pancreatitis (AP) is a frequent, mild, self-limiting condition with only minor or temporary systemic symptoms. In the evaluation of AP, imaging by CT or MRI is helpful for diagnosis as well as for identifying regional pancreatic problems and directing interventional therapies. A retrospective analysis of a prospectively collected database Material and methods: was performed. The demographic, clinical, and laboratory data of the 40 cases of acute pancreatitis in patients were reviewed for this study. 40 patients underwent CECT or MRI within 1 week of onset of symptoms. A single radiologist performed imaging studies and recorded all pancreatic, peripancreatic, and extrapancreatic ndings and complications. According to CTSI, the number of patients with mild moderate and Results: severe disease were 19, 14 and 7 respectively; According to MCTSI, the number of patients with mild, moderate and severe disease were 7, 18, 15 respectively. Mean length of hospital stay and ICU stay was 4.48±2.03 and 1.7±2.11 respectively. Both the scoring systems more accurately correlated with the length of ICU stay, organ failure and necrosectomy and accurately correlated with infection and percutaneous catheter drainage. MCTSI showed superior and better Conclusion: correlation with disease severity than CTSI. There was statistical signicant association noted with CTSI and MCTSI each with the severity parameters and outcome assessed.

Diagnosis and treatment of blunt high-grade pancreatic trauma

The clinical data of 20 patients with blunt high-grade pancreatic trauma who were admitted to the Department of Hepatobiliary and Pancreatic Surgery of Changhai Hospital Affiliated to Naval Military Medical University from December 2003 to February 2022 were retrospectively analyzed. There were 15 males and 5 females with a median age of 39 years (range: 14-54 years). The degree of pancreatic injury was graded according to the American Association for the Surgery of Trauma (AAST) scale, including 10 cases of grade Ⅲ (50%), 8 cases of grade Ⅳ (40%), and 2 cases of grade Ⅴ (10%). Then, the strategy of diagnosis and treatment for blunt high-grade pancreatic trauma was summarized. The diagnostic rate of CT was 78.9%. Finally, 17 cases (85%) were cured and 3 cases (15%) died. Among the 10 patients with grade Ⅲ pancreatic injury, 7 cases received distal pancreatectomy and splenectomy, 1 case received distal pancreatectomy with spleen preserved, 1 case received pancreatic duct stent placement under endoscopic retrograde cholangiopancreatography (ERCP) and percutaneous catheter drainage (PCD), and 1 case received only PCD. Among 8 cases of grade Ⅳ, 3 cases underwent Roux-en-Y pancreaticojejunostomy, 1 case received distal pancreatectomy and splenectomy, 1 case underwent distal pancreatectomy with spleen preserved, 2 cases received necrotic tissue removal+external drainage of pancreatic duct+abdominal drainage, and 1 case received exploratory laparotomy and gauze packing hemostasis. For 2 cases of grade Ⅴ, 1 underwent pylorus preserving pancreaticoduodenectomy, and the other case underwent pancreaticoduodenectomy combined with right hemicolectomy and splenectomy. Therefore, the treatment of blunt high-grade pancreatic trauma should follow the individualized treatment strategy, pay attention to the control of bleeding, extensive external drainage, appropriate debridement and resection and rational application of damage control surgery, select appropriate patients for conservative treatment, and ultimately benefit the patient.

Effectiveness of a postoperative continuous irrigation system via a catheter following implant-based breast reconstruction

Background Implant-based breast reconstruction is a technique frequently used for breast reconstruction. Infection and inflammation are considered to be the most troublesome complications of implant-based breast reconstruction and can lead to capsular contracture or implant failure. To date, however, only a few methods have been proposed to prevent these complications. Therefore, the authors introduce a simple irrigation system using indwelling drain catheters to decrease postoperative inflammation.Methods Continuous saline irrigation was performed once per day for 3 days immediately after prosthesis-based breast reconstruction. Normal saline (500 mL) was inserted into the implant pocket through a superomedial-oriented drain catheter and drained through an inferolateral-oriented drain catheter using a suction device. Inflammatory indicators, including C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), white blood cell count (WBC), and postoperative complications were compared between the non-irrigation and irrigation groups.Results This study included 37 patients divided into two groups (20 non-irrigation and 17 irrigation). An analysis of inflammatory indicators revealed that the peak CRP level in the irrigation group was significantly lower than that in the non-irrigation group, while no statistically significant differences were found for the other mediators (ESR and WBC). In the immediate postoperative period, continuous irrigation effectively washed out tissue debris and blood clots within the implant pocket, which helped maintain the function of the drain catheter and decrease pro-inflammatory mediators.Conclusions This irrigation method was simple and cost-effective for decreasing inflammation within the breast pocket. Furthermore, it can also be applied to infected breast pockets in combination with antibiotics.

Introduction to interventional radiology's role in palliative care for children with cancer: A COG Diagnostic Imaging Committee/SPR Oncology Committee White Paper.

As palliative care continues to be an area of increasing emphasis in pediatric oncology programs, it is important to raise awareness about minimally invasive, image-guided procedures that can supplement more conventional palliative interventions, such as systemic analgesics, external beam radiation, and locoregional anesthesia. These procedures, when performed for appropriately selected patients, can often facilitate discharge from an inpatient facility, and help patients meet their end-of-life goals. This article specifically discusses three palliative procedures performed by interventional radiologists that can assist pediatric palliative care teams in: (a) percutaneous thermal ablation of painful bone metastases, (b) cryoneurolysis, and (c) tunneled drainage catheter placement for malignant pleural effusions and ascites.

Use of thoracoscopy for thoracic sympathetic nerve block in primary hyperhidrosis

Thoracic sympathetic nerve block (TSNB) has been widely used in the treatment of neuropathic pain. To reduce block failure rates, TSNB is assisted with several modalities including fluoroscopy, computed tomography, and ultrasonography. The present study describes our experience assessing the usefulness of thoracoscopy in TSNB for predicting compensatory hyperhidrosis before sympathectomy in primary hyperhidrosis. From September 2013 to October 2021, TSNB was performed under local anesthesia using a 2-mm thoracoscope in 302 patients with severe primary hyperhidrosis. Among the 302 patients, 294 were included for analysis. The target level of TSNB was T3 in almost all patients. The mean procedure time was 21 min. Following TSNB, the mean temperature of the left and right palms significantly changed from 31.5 to 35.3 °C and from 31.5 to 34.8 °C, respectively. With TSNB, primary hyperhidrosis was relieved in all patients. Pneumothorax occurred in six patients, in which no chest tube insertion was required. One patient developed hemothorax and was discharged the next day after small-bore catheter drainage. Transient ptosis developed in 10 patients and improved within a day in all patients. Our experiences showed that thoracoscopic TSNB is accurate, safe, and feasible to block the thoracic sympathetic nerve in patients with severe primary hyperhidrosis.

The timing of pericardial drainage catheter removal and restart of the anticoagulation in patients suffered from perioperative pericardial tamponade during atrial fibrillation catheter ablation and uninterrupted dabigatran: Experiences from 20 cases

Objective: To investigate the timing of pericardial drainage catheter removal and restart of the anticoagulation in patients with atrial fibrillation (AF) suffered from perioperative pericardial tamponade during atrial fibrillation catheter ablation and uninterrupted dabigatran. Methods: A total of 20 patients with pericardial tamponade, who underwent AF catheter ablation with uninterrupted dabigatran in Beijing Anzhen Hospital from January 2019 to August 2021, were included in this retrospective analysis. The clinical characteristics of enrolled patients, information of catheter ablation procedures, pericardial tamponade management, perioperative complications, the timing of pericardial drainage catheter removal and restart of anticoagulation were analyzed. Results: All patients underwent pericardiocentesis and pericardial effusion drainage was successful in all patients. The average drainage volume was (427.8±527.4) ml. Seven cases were treated with idarucizumab, of which 1 patient received surgical repair. The average timing of pericardial drainage catheter removal and restart of anticoagulation in 19 patients without surgical repair was (1.4±0.7) and (0.8±0.4) days, respectively. No new bleeding, embolism and death were reported during hospitalization and within 30 days following hospital discharge. Time of removal of pericardial drainage catheter, restart of anticoagulation and hospital stay were similar between patients treated with idarucizumab or not. Conclusion: It is safe and reasonable to remove pericardial drainage catheter and restart anticoagulation as soon as possible during catheter ablation of atrial fibrillation with uninterrupted dabigatran independent of the idarucizumab use or not in case of confirmed hemostasis.

Concomitant brain abscess and spinal cord abscess in an immunocompetent teenage male: illustrative case.

Multiple bilateral brain abscesses occur rarely in immunocompetent patients. Hematogenous spread to the central nervous system (CNS) allows suppuration and abscess formation in the privileged immune environment of the CNS; hematogenous spread to the spinal cord is extremely rare and the combination of multifocal brain abscesses and intramedullary abscesses has not been reported. This report presents a rare presentation and diagrams a treatment algorithm involving iterative minimal access surgeries and prolonged medical management. The authors present a case of an 18-year-old male with numerous multifocal and bilateral intraparenchymal abscesses and a medically resistant C5 intramedullary spinal cord abscess. The symptomatic patient had a left oculomotor palsy and left hemiparesis, ultimately undergoing ultrasound-guided aspiration of abscesses in the left frontal and left cerebral peduncle. Following transient motor improvement, he evolved tetraparesis prompting spinal cord imaging and emergent ultrasound-guided needle aspiration of an occult C5 intramedullary spinal cord abscess. The patient received appropriate medical therapy, completed inpatient rehabilitation, and made a full recovery. Needle- and ultrasound-guided catheter drainage of CNS abscesses should be considered for symptomatic lesions. Following the neurological examination closely is extremely important; if the expected neurological improvement is delayed or regresses, then expanded imaging is warranted.

Thermal and Postural Effects on Fluid Mixing and Irrigation Patterns for Intraventricular Hemorrhage Treatment

Intraventricular hemorrhage is characterized by blood leaking into the cerebral ventricles and mixing with cerebrospinal fluid. A standard treatment method involves inserting a passive drainage catheter, known as an external ventricular drain (EVD), into the ventricle. EVDs have common adverse complications, including the occlusion of the catheter, that may lead to permanent neural damage or even mortality. In order to prevent such complications, a novel dual-lumen catheter (IRRAflow®) utilizing an active fluid exchange mechanism has been recently developed. However, the fluid dynamics of the exchange system have not been investigated. In this study, convective flow in a three-dimensional cerebral lateral ventricle with an inserted catheter is evaluated using an in-house lattice-Boltzmann-based fluid–solid interaction solver. Different treatment conditions are simulated, including injection temperature and patient position. Thermal and gravitational effects on medication distribution are studied using a dye simulator based on a recently-introduced (pseudo)spectral convection–diffusion equation solver. The effects of injection temperature and patient position on catheter performance are presented and discussed in terms of hematoma irrigation, vortical structures, mixing, and medication volume distribution. Results suggest that cold-temperature injections can increase catheter efficacy in terms of dye distribution and irrigation potential, both of which can be further guided by patient positioning.

Tips and Techniques for Traversing the Impassable Biliary Stricture

AbstractBiliary obstruction is a common indication for referral to interventional radiology, particularly when endoscopic retrograde cholangiopancreatography has failed or is not possible due to postsurgical anatomy. The standard approach to percutaneous transhepatic biliary drainage involves gaining needle access to a peripheral bile duct, followed by advancement of a guidewire and drainage catheter across the obstruction and into bowel to allow internal drainage. While most cases of biliary obstruction are managed successfully with this conventional approach, in some situations it is not possible to traverse the occlusion with a guidewire and catheter, and thus advanced techniques may be required. This article has reviewed the available strategies for managing the impassable biliary obstruction.

Arterioportal fistula with hepatic artery pseudoaneurysm: A rare complication of percutaneous transhepatic biliary drainage

We describe a rare complication of percutaneous transhepatic biliary drainage in a 51-year-old female with recurrent hilar cholangiocarcinoma. The patient presented with blood-mixed pericatheter leak of bile, 1 month after placement of a 10F ring biliary internal-external drainage catheter through the left-sided biliary radical. Color Doppler and triphasic computed tomography angiography revealed a pseudoaneurysm arising from segment 3 branch of the left hepatic artery and an arterioportal fistula immediately distal to the pseudoaneurysm. Endovascular coil embolization of the hepatic artery proximal to the pseudoaneurysm was done which resulted in occlusion of the pseudoaneurysm and fistula as well as clinical improvement in the symptoms.

The implementation of enhanced recovery after surgery pathway in patients undergoing posterior thoracolumbar fusion for degenerative spinal deformity

PurposeThe prevalence of degenerative spinal deformity (DSD) and the increased cost of correction surgery impose substantial burdens on the health care and insurance system. The aim of our study was to investigate the effects of the implementation of Enhanced Recovery After Surgery (ERAS) protocol on postoperative outcomes after complex spinal surgery.MethodsA retrospective analysis of prospectively established database of DSD was performed. The consecutive patients who underwent open correction surgery for degenerative spinal deformity between August 2016 and February 2022 were reviewed. We extracted demographic data, preoperative radiographic parameters, and surgery-related variables. The ERAS patients were 1:1 propensity-score matched to a historical cohort by the same surgical team based on age, gender, BMI, and number of levels fused. We then compared the length of hospital stay (LOS), physiological functional recovery, and the rates of complications and readmissions within 90 days after surgery between the groups.ResultsThere were 108 patients included, 54 patients in the ERAS cohort, and 54 patients matched control patients in the historical cohort. The historical and ERAS cohorts were not significantly different regarding demographic characteristics, comorbidities, preoperative parameters, operative time, and reoperation rate (P > 0.05). Patients in the ERAS group had significantly shorter postoperative LOS (12.0 days vs. 15.1 days, P = 0.001), average days of drain and urinary catheters placement (3.5 days vs. 4.4 days and 1.9 days vs 4.8 days, respectively), and lower 90-day readmission rate (1.8% vs. 12.9%, P = 0.027). The first day of assisted-walking and bowel movement occurred on average 1.9 days (2.5 days vs. 4.4 days, P = 0.001) and 1.7 days (1.9 days vs. 3.6 days, P = 0.001) earlier respectively in the ERAS group. Moreover, the rate of postoperative urinary retention (3.7% vs. 16.7%, P = 0.026) and surgical site infection (0% vs. 7.4%, P = 0.046) were significantly lower with ERAS protocol applied.ConclusionsOur study confirmed that the ERAS protocol was safe and essential for patients undergoing thoracolumbar deformity surgery for DSD. The ERAS protocol was associated with a shorter postoperative LOS, a lower rate of 90-day readmission, less rehabilitation discharge, and less postoperative complications.

Ultrasound-Guided Pigtail Catheter Drainage: An Effective Alternative to Exploratory Laparotomy.

Introduction It has been long established that open surgeries were the only options available for the management of intra-abdominal abscesses or collections. These were associated with increased morbidity and mortality. Traditionally, the idea of percutaneous needling could not gain popularity due to poor localization of collections. However, with the advent of ultrasound, percutaneous pigtail-catheter drainage has proven to be minimally invasive and allows precise localization of the drainage site. Objectives To study the effectiveness of ultrasound-guided pigtail catheter drainage as an alternative to exploratory laparotomy for the management of intra-abdominal abscesses or collections. Materials and methods A total of 48 patient cases, which included liver abscesses, perinephric collections, malignant ascites, splenic collections, pseudocysts, and psoas abscesses, were studied prospectively in a medical college in India from October 2020 to October 2021. The efficacy of the drainage was assessed by serial ultrasound. Results Out of 48 patients, 34 were male and 14 were female, ranging in age from 19 to 64 years, who were diagnosed with intra-abdominal abscesses or collections and underwent ultrasound-guided pigtail catheter drainage. The average hospital stay for patients was 2.5 days. They were followed up periodically for three months post-procedure, and none had significant complications or recurrence. Conclusion The pigtail catheter is the treatment of choice for liquefied intra-abdominal collections or abscesses, which helps to reduce post-procedure hospital stays and complications. Contribution This article reiterates the use of minimally invasive techniques in place of open surgeries with less morbidity.

Comparison of Combined Intraarticular and Intravenous Administration of Tranexamic Acid with Intraarticular and Intravenous Alone in Patients Undergoing Total Knee Arthroplasty without Drainage Catheter: A Clinical Trial Study.

We aimed to assess the most effective route for Tranexamic acid (TXA) administration among Intraarticular (IA), Intravenous (IV), and combined IA/IV for Total Knee Arthroplasty (TKA) surgeries. A double-blinded clinical trial was run on 147 TKA candidates. Blood loss and hemoglobin (Hb) drop were evaluated using the Gross and Nadler formula in three matched case groups administered TXA during the TKA through IV, IA, or combined IA/IV route. Tourniquet was used on all operations for controlling intraoperative blood loss. No drainage catheter was used for the cases. The combined group showed an average blood loss of 630±252 ml, which was significantly lower than that in the IV group (878±268 ml, P<0.01) and the IA group (774±288 ml, P=0.03). Furthermore, the mean Hb and hematocrit drop were significantly lower in the combined group, compared to the other two groups, 48 and 72 h postoperatively (P<0.05). The combined IA/IV route had a 28% and 19% reduction of blood loss, compared to the IV or IA methods, respectively. Therefore, using TXA via the combined IA/IV route may be more effective for reducing perioperative blood loss following TKA surgery using a tourniquet without drain placement.
