A short report on the current landscape of Artificial Intelligence (AI) in vascular surgery in Pakistan.

This study focuses on the current applications, potential, and challenges to Artificial Intelligence (AI) integration in vascular surgery with specific emphasis on its relevance in Pakistan. Despite the benefits of AI in vascular surgery, there is a substantial gap in its adoption in Pakistan compared to global standards. In our context with limited resources and a scarcity of vascular surgeons, AI can serve as a promising solution.

Role of Simulated Training for Carotid Endarterectomy: A Systematic Review.

Vascular surgery trainees often do not get to perform carotid endarterectomy (CEA) directly on the patients as it requires meticulous surgical technique and has a high risk of procedure-related complications. Hence, the role of simulation in training future vascular surgeons becomes essential. This review aims to assess the types and utility of simulators available for CEA.

Objective: To assess the types and effectiveness of simulators present for open varicose vein surgery.

Methods: The systematic review was conducted at The Aga Khan University Hospital Karachi and comprised studies published from 1st January 2000 to 30th June 2020 related to open varicose vein surgical procedures done on simulators. Databases searched were PubMed, Medline, Google Scholar, Cochrane and Scopus using appropriate key words.

Predictors of Poor Quality of Life after Primary Lower Limb Deep Venous Thrombosis: A Perspective from a Developing Nation.

: We aimed to determine predictors of poor long term quality of life, using the VEINES Quality of Life (QOL) questionnaire, in patients with lower limb deep venous thrombosis (DVT). : This study included adult patients with primary lower limb DVT between January 2007 and December 2017. Post thrombotic syndrome (PTS) was assessed using the Villalta score and Quality of Life (QoL) by the VEINES quality of life questionnaire.

May-Thurner Syndrome: A Cause of Acute Left Iliac Vein Obstruction in Early Postpartum Period: A Case Report.

May-Thurner syndrome (MTS) is a rare disease common in middle aged females, characterised by left-sided lower limb Deep vein thrombosis (DVT) due to compression of the left iliac vein by the overriding right iliac artery. Pregnanc y and puerperal phases are one of the hypercoagulable states further predisposing towards th rombu s format io n. Treatme nt in c lu de s both conservative and interventional (venous thrombectomy with or without stenting).

Comparison of Upper Limb Translocated Femoral Vein and Prosthetic Arteriovenous Bridge Grafts.

Introduction Native veins are an ideal option for dialysis in a patient with chronic kidney disease (CKD) as compared to a prosthetic graft. Femoral vein (FV) translocation to the upper arm is also an alternative to a prosthetic graft as reported in the literature when all options of using the native veins of the arms are exhausted. Thus, we aimed to compare the patency of the upper limb translocated FV arteriovenous fistula (AVF) with a prosthetic arteriovenous bridge graft (AVBG).

Operative Techniques to Prevent Dialysis Access-associated Steal Syndrome in High-risk Patients Undergoing Surgery for Hemodialysis Access: A Systematic Review.

Up to 10% of patients suffer from various degrees of dialysis access-associated steal syndrome (DASS) after surgery for hemodialysis access. This systematic review was conducted to find out optimal intra-operative techniques to prevent DASS in high-risk patients. This systematic review is registered with PROSPERO (2017:CRD42017060804).

Template operative note, a better documentation.

Operative notes are a valuable part of patient's medical record, and carry the medico-legal significance. One way of improving it is to introduce the template form operative notes. Only few studies have been done worldwide to compare both the forms of operative notes.
