RESUMO
BACKGROUND: Inadvertent intra-arterial injection of sclerosants is an uncommon adverse event of both ultrasound-guided and direct vision sclerotherapy. This complication can result in significant tissue or limb loss and significant long-term morbidity. OBJECTIVES: To provide recommendations for diagnosis and immediate management of an unintentional intra-arterial injection of sclerosing agents. METHODS: An international and multidisciplinary expert panel representing the endorsing societies and relevant specialities reviewed the published biomedical, scientific and legal literature and developed the consensus-based recommendations. RESULTS: Actual and suspected cases of an intra-arterial sclerosant injection should be immediately transferred to a facility with a vascular/interventional unit. Digital Subtraction Angiography (DSA) is the key investigation to confirm the diagnosis and help select the appropriate intra-arterial therapy for tissue ischaemia. Emergency endovascular intervention will be required to manage the risk of major limb ischaemia. This includes intra-arterial administration of vasodilators to reduce vasospasm, and anticoagulants and thrombolytic agents to mitigate thrombosis. Mechanical thrombectomy, other endovascular interventions and even open surgery may be required. Lumbar sympathetic block may be considered but has a high risk of bleeding. Systemic anti-inflammatory agents, anticoagulants, and platelet inhibitors and modifiers would complement the intra-arterial endovascular procedures. For risk of minor ischaemia, systemic oral anti-inflammatory agents, anticoagulants, vasodilators and antiplatelet treatments are recommended. CONCLUSION: Inadvertent intra-arterial injection is an adverse event of both ultrasound-guided and direct vision sclerotherapy. Medical practitioners performing sclerotherapy must ensure completion of a course of formal training (specialty or subspecialty training, or equivalent recognition) in the management of venous and lymphatic disorders (phlebology), and be personally proficient in the use of duplex ultrasound in vascular (both arterial and venous) applications, to diagnose and provide image guidance to venous procedure. Expertise in diagnosis and immediate management of an intra-arterial injection is essential for all practitioners performing sclerotherapy.
RESUMO
Chemoports are often required for oncological patients requiring repeated blood draws and long-term drug therapy. However, complications such as dislodgement, fracture, thrombosis, and venous occlusion may occur if the ports remain unremoved when not in use. Nonetheless, existing techniques require multiple accesses or release of the stuck catheter tip to retrieve the catheter, making the procedure inconvenient. We present our experience with a technique using the Bard Denali inferior vena cava filter retrieval kit to remove a stuck or fractured chemoport catheter through a single vascular access. The technique was performed in two female patients with satisfactory results (complete retrieval of broken chemoports) and an event-free follow-up period. The entire procedure was completed within 15-30 minutes with fluoroscopic time under two minutes. The technique allows for better case management by simplifying the procedure, reducing radiation, and improving workflow efficiency in the operating room.
RESUMO
BACKGROUND Thrombosis with thrombocytopenia syndrome (TTS), including vaccine-induced immune thrombotic thrombocytopenia (VITT), is an extremely rare adverse effect, mostly seen after initial vaccination with the viral vector-based AstraZeneca-Oxford COVID-19 vaccine. It is characterized by mild to severe thrombocytopenia and venous or arterial thrombosis. CASE REPORT Herein, we present a case of an 18-year-old male patient who developed Level 1 TTS (probable VITT) eight days after immunization with the ChADOx1 nCOV-19 vaccine (Covishield; AZ-Oxford). Initial investigations revealed severe thrombocytopenia, hemiparesis, and intracranial hemorrhage, after which the patient was treated conservatively. However, a decompressive craniotomy was performed later due to patient deterioration. One week after surgery, the patient developed bilious vomiting, lower-gastrointestinal bleeding, and abdominal distension. An abdominal CT scan was performed that showed thrombosis of the portal vein with occlusion of the left iliac vein. The patient underwent an exploratory laparotomy followed by resection and anastomosis of the small bowel due to massive gut gangrene. Due to persistent thrombocytopenia after surgery, intravenous immune globulin (IVIG) was administered. The platelet count increased thereafter, and the patient stabilized. He was discharged on the 33rd day after admission and was followed up for a year. No post-hospitalization complications were observed in the follow-up period. CONCLUSIONS Although vaccines have been proven to be highly safe and effective to end the Coronavirus Disease 2019 (COVID-19) caused pandemic, there is still a small risk of developing rare complications, including TTS and VITT. Early diagnosis and prompt intervention are key for patient management.

Published scientific evidence demonstrate the current spread of healthcare misinformation in the most popular social networks and unofficial communication channels. Up to 40% of the medical websites were identified reporting inappropriate information, moreover being shared more than 450,000 times in a 5-year-time frame. The phenomenon is particularly spread in infective diseases medicine, oncology and cardiovascular medicine. The present document is the result of a scientific and educational endeavor by a worldwide group of top experts who selected and analyzed the major issues and related evidence-based facts on vein and lymphatic management. A section of this work is entirely dedicated to the patients and therefore written in layman terms, with the aim of improving public vein-lymphatic awareness. The part dedicated to the medical professionals includes a revision of the current literature, summing up the statements that are fully evidence-based in venous and lymphatic disease management, and suggesting future lines of research to fulfill the still unmet needs. The document has been written following an intense digital interaction among dedicated working groups, leading to an institutional project presentation during the Universal Expo in Dubai, in the occasion of the v-WINter 2022 meeting.

Venous ulcer is an extremely common aetiology of lower extremity ulceration, which affects approximately 1% population in most of the countries, and the incidence rate increases with age and female gender. Proper assessment and diagnosis of both the patient and ulcer are inevitable in order to differentiate venous ulcers from other lower extremity ulceration and to frame an adequate and individualised management plan. Venous ulcers generally persist for weeks to many years and are typically recurrent in nature. This consensus aims to present an evidence-based management approach for the patients with venous ulcers. Various management options for venous ulcers include compression therapy, minimally invasive procedures like sclerotherapy and ablation techniques, surgical procedures, debridement and medical management with micronised purified flavonoid fraction (MPFF). Compression therapy is the mainstay treatment for venous ulcer. However, in failure cases, surgery can be preferred. Medical management with MPFF as an adjuvant therapy to standard treatment has been reported to be effective and safe in patients with venous ulcer. In addition to standard therapy, diet and lifestyle modification including progressive resistance exercise, patient education, leg elevation, weight reduction, maintaining a healthy cardiac status and strong psychosocial support reduces the risk of recurrence and improves the quality of life in patients with venous ulcer.

RESUMO
The purpose of this study was to demonstrate the use of endovascular technology in the management of peripheral infected aneurysms in high-risk patients as a temporary measure or definitive solution. Five cases underwent successful endovascular stenting of infected aneurysms of the subclavian, femoral, and carotid arteries. All these patients were at high risk for open surgery. Covered stents were placed by percutaneous approach under local anesthesia in all patients. Postoperatively, antibiotics were continued for 3 months. A literature review using the Medline database was also undertaken, and all the relevant papers on endovascular management of peripheral infected aneurysms were taken into account. Stent deployment was successful in all patients. One patient died of mediastinal sepsis and another from type A aortic dissection 5 weeks later. Two patients required drainage of the infected hematoma. Three patients did well at a median follow-up of 1 year, with no evidence of sepsis. A review of the literature shows promising early and midterm results. Most early reports were of single cases, reflecting the low incidence of peripheral infected aneurysms. We conclude that further development of endoluminal techniques and long-term follow-up to establish the durability of stenting could potentially lead to a decrease in the high morbidity and mortality rates associated with infected aneurysmal disease in this high-risk group of patients.

BACKGROUND: Pancreatic necrosectomy for necrotizing pancreatitis is a formidable operation. There are limited data from the Indian subcontinent regarding outcome and recent trends in management. METHODS: Patients undergoing pancreatic necrosectomy over a 12-year period were identified from a prospective database. Data regarding the hospital course, complications and outcome were extracted by case file review. Descriptive statistics were used to present the data. An attempt was made to identify trends in management and outcome over the study period. RESULTS: One hundred and eighteen patients underwent necrosectomy. The median age was 39.5 years (interquartile range, 32-46). Median Acute Physiology And Chronic Health Evaluation II score at admission was 8 (interquartile range, 6-10). Thirty-nine patients (33%) had organ failure at admission. Patients underwent surgery a median of 23 days (interquartile range, 14-34) after onset of illness. There was high incidence of loco-regional complications (68/118, 58%) and organ failure (88/118, 75%) in the postoperative period. The mortality rate was 38%. There was an increase in the median onset to surgery interval (17 vs 25.5 days; P = 0.001), increased use of percutaneous interventions (20 vs 36%; P = 0.05) and decreased mortality (47 vs 29%; P = 0.052) in the later half of the study period. CONCLUSION: Pancreatic necrosectomy continues to be associated with significant morbidity and mortality in India. A trend towards increased use of percutaneous interventions and delayed surgery is evident.

BACKGROUND: Pulmonary complications remain a leading cause of morbidity after major abdominal operations. OBJECTIVE: To compare pulmonary function and the frequency of pulmonary complications after laparoscopic cholecystectomy (LC) and open cholecystectomy (OC). METHODS: Fifty-five patients with symptomatic gallstone disease undergoing elective cholecystectomy (LC 40, OC 15) under general anesthesia were evaluated using pulmonary function tests (forced vital capacity [FVC], forced expiratory volume at 1 second [FEV1], and forced expiratory flow at 25% to 75% [FEF25% -75%], chest X-ray and pulse oximetry before and after surgery. RESULTS: FVC, FEV1 and FEF25% -75% decreased by 21.5%, 21.2% and 30.3%, respectively, on postoperative day 1 following LC, and by 44.3%, 46.2% and 58.3%, respectively, after OC. Chest X-ray showed atelectasis in 15% of patients undergoing LC and 45% of those with OC. CONCLUSION: Impairment in pulmonary function after LC was less marked than after OC.

BACKGROUND AND AIM: Surgery for pancreatic necrosis complicating acute severe pancreatitis carries a high risk of morbidity and mortality. We evaluated the efficacy of necrosectomy and closed lesser sac lavage as a method of management of pancreatic necrosis. METHODS: Fifty-eight patients with pancreatic necrosis who underwent pancreatic necrosectomy consecutively in a tertiary care referral center were retrospectively analyzed. The technique of necrosectomy and postoperative lavage is described in detail. Details regarding the patient profile, disease severity, surgical details, postoperative morbidity, repeat interventions and the mortality are presented. RESULTS: Of the 58 patients, irrigation was able to be started in 48. Lavage was able to be continued until disease resolution or death in all but 10 patients. Post-operative locoregional complications were residual abscesses in 10, bleeding in eight, enteric fistulae in 12 and pancreatic fistulae in nine. Six patients needed postoperative percutaneous procedures, while 16 patients needed repeat surgery. Seventeen patients died (29%), all of whom had multiple organ failure involving more than two organs, while 11 developed sepsis. CONCLUSION: Pancreatic necrosectomy and postoperative closed lesser sac lavage is an effective method of managing these patients, with acceptable morbidity, re-operation rates and mortality.

BACKGROUND: Vascular complications resulting from i.v. drug abuse constitute a range of clinical problems from simple to serious. In addition, patients who present with these complications frequently have viral infections, which are a hazard to health care workers. PATIENTS AND METHODS: The present study is a retrospective review of 46 male drug addicts with 52 vascular complications (45 arterial, seven venous). Pseudoaneurysm of the femoral artery was the most common complication (n = 35). Fourteen of these patients underwent ligation of the common, superficial and deep femoral arteries above and below the pseudoaneurysm. Twenty-one underwent bipolar ligation of the common femoral artery after complete excision of the pseudoaneurysm. The decision to revascularize was based on the presence or absence of postligation Doppler signal. Arterial reconstruction was performed in five patients. All eight brachial artery pseudoaneurysms were ligated and excised, and deep vein thrombosis was managed with anticoagulation. RESULTS: There was no mortality but three patients had to undergo late amputations of the lower limb after successful salvage following the initial surgery. The median postoperative ankle-brachial indices, after bipolar and triple ligations were 0.51 and 0.46, respectively. Positive blood cultures were present in 30% of patients and tissue cultures were positive in 72%, the most common organism isolated was methicillin-sensitive Staphylococcus aureus. Six patients were positive for viral markers. The median hospital stay was 43 days. CONCLUSION: Ligation and excision of pseudoaneurysms without revascularization is safe for drug addicts provided it is based on the presence of a postligation Doppler signal.
