An original method of great saphenous vein bypass protection during reconstructive arterial surgery is described. The use of a reinforced prosthetic support (Ringed PTFE), surrounding the vein, avoids possible compression by anatomical structures and strangulation by scar tissue after reoperation. This technique can also prevent eventual dilatation of the vein graft. Since 1981, this technique has been successfully applied to 30 selected patients. On the basis of clinical experience, the authors conclude that this method is safe and effective, and may increase the long-term patency rate of saphenous vein grafts.

Objective: The aim of this study was to compare anterior accessory saphenous vein (AASV) reflux after standard endovenous laser ablation (EVLA) vs. flush EVLA (fEVLA) of the great saphenous vein (GSV).
Methods: This was as randomised, single blind, controlled trial (Dutch Trial Register, NL5283).

Background: BEST-CLI established the superiority of single-segment great saphenous vein (ssGSV) conduits for revascularization in patients with CLTI; however, the generalizability of these data is unknown. Thus, we aimed to validate the long-term results of open surgical bypass (BPG) versus angioplasty with or without stenting (PTA/S) using the BEST-CLI inclusion and randomization criteria.
Methods: All patients undergoing a first-time lower extremity revascularization for CLTI at our institution from 2005 to 2022 were retrospectively reviewed.

Carotid artery stenting (CAS) has become a favoured alternative to surgical carotid endarterectomy (CEA) in select cases of critical internal carotid artery (ICA) occlusion. However, complications such as stent migration or entrapment can occur, necessitating prompt diagnosis and intervention. We present a case of a 75-year-old diabetic male who underwent CAS for recurrent presyncope at a private hospital, and during the procedure of CAS the stent was migrated and its proximal part was impacted in the critically narrowed part of the ICA.

Background: This study aims to evaluate the prognostic value of the inflammatory indices i.e. Platelet Lymphocyte Ratio (PLR), Neutrophil Lymphocyte Ratio (NLR), and Systemic Immune Inflammation Index (SII) as potential predictors of Major Adverse Cardiovascular Event (MACE) in patients undergoing Primary Percutaneous Coronary Intervention (PPCI) on Saphenous Vein Graft (SVG) with a history of Coronary Artery Bypass Graft (CABG).

Inguinal masses have a large variety of causes, ranging from inguinal hernias to soft tissue sarcomas. One of the less prevalent causes is vascular origin. Venous aneurysms, unlike their arterial counterparts, are seen seldomly and experience in management of these cases is scarce.
