The use of endo-vascular balloon tamponade technique for the removal of a misplaced nephrostomy tube in the inferior vena cava: A case report

AbstractIntroductionInadvertent placement of a nephrostomy tube into the inferior vena cava (IVC) is an extremely rare complication with few reported cases in the literature.Case presentationWe present a lady with obstructive uropathy in a solitary kidney in whom an attempt by the community radiologist to place a nephrostomy tube was complicated by wrong insertion into the IVC. This report illustrates how a safe non- surgical removal of this tube using an intravenous balloon tamponade technique was successfully applied.DiscussionIntravenous placement of nephrostomy catheters into the inferior vena cava is extremely rare complication. A few case reports have been published in the literature. The majority of these cases were removed in the operating room under general anesthesia. Using Intravenous balloon tamponade technique for removal has not been previously reported.ConclusionIntravenous balloon tamponade technique is effective and is a good minimally invasive alternative to surgical removal of misplaced nephrostomy tube from IVC

Recurrent scrotal Arteriovenous Malformation as a Slowly Increasing Left Testicular Swelling: A case report

Arteriovenous malformations (AVMs) are benign vascular lesions. Although, the majority of AVMs occur in the central nervous system, there are published reports of AVMs involving all systems including the scrotum, kidney, and uterus. Herein we report a case of 37 years old male presented with recurrent gradual scrotal swelling for 4 years attributed to scrotal AVM. Embolization was done but one year later his symptoms reoccurred. As a result, left partial scrotal wall excision was carried out without complications. Keywords: arteriovenous malformation, AVM, scrotal swelling, scrotal malformation

Arab's research productivity and contribution to vascular and interventional radiology literature

Objective: Vascular and interventional radiology (VIR) is one of the most rapidly growing fields of medicine. In this report, we evaluate the contribution of Arab countries to VIR publications and literature. Materials and Methods: Using PubMed database, we reviewed the total number of VIR publications from all Arab countries. In addition, we evaluated the total number of IR articles from each individual country, number of publications in VIR specialty journals and the type of manuscripts. Results: Seventy-four articles from different Arab countries were published in different journals from 1988 to 2016. Only 11 (14.9') articles were published in interventional radiology journals. The majority of these publications were from Kingdom of Saudi Arabia 31 (41.9') articles, followed by 20 (27.02') articles from Egypt, 7 articles (9.5') from Jordan, 6 articles (8.1) from Kuwait, and 4 articles (5.4') from Morocco. There was one article (1.4') from Lebanon, United Arab Emirates, Oman, Tunis, and Qatar. Nine (12.2') articles from different Arab countries were published in the two highest impact specialty journals in VIR. Conclusion: This review demonstrated the limited number of publications and poor contribution of Arab countries to VIR literature. Collaborative efforts of researchers, governments, and funding bodies are needed to improve research output in this important field of medicine

SARS-CoV-2 vaccination modelling for safe surgery to save lives: data from an international prospective cohort study

Background: Preoperative SARS-CoV-2 vaccination could support safer elective surgery. Vaccine numbers are limited so this study aimed to inform their prioritization by modelling. Methods: The primary outcome was the number needed to vaccinate (NNV) to prevent one COVID-19-related death in 1 year. NNVs were based on postoperative SARS-CoV-2 rates and mortality in an international cohort study (surgical patients), and community SARS-CoV-2 incidence and case fatality data (general population). NNV estimates were stratified by age (18-49, 50-69, 70 or more years) and type of surgery. Best- and worst-case scenarios were used to describe uncertainty. Results: NNVs were more favourable in surgical patients than the general population. The most favourable NNVs were in patients aged 70 years or more needing cancer surgery (351; best case 196, worst case 816) or non-cancer surgery (733; best case 407, worst case 1664). Both exceeded the NNV in the general population (1840; best case 1196, worst case 3066). NNVs for surgical patients remained favourable at a range of SARS-CoV-2 incidence rates in sensitivity analysis modelling. Globally, prioritizing preoperative vaccination of patients needing elective surgery ahead of the general population could prevent an additional 58 687 (best case 115 007, worst case 20 177) COVID-19-related deaths in 1 year. Conclusion: As global roll out of SARS-CoV-2 vaccination proceeds, patients needing elective surgery should be prioritized ahead of the general population
