Adventitial cystic disease is an uncommon condition that is characterized by the collection of mucinous material that accumulates in the adventitial layer of the artery. Predominantly, this entity affects the popliteal artery, whereas it is extremely rare in the radial artery. We report a 72-year-old female patient that underwent surgical treatment of an adventitial cyst of the right radial artery. The involved arterial segment was resected, and reconstruction by means of the interposition of a saphenous vein graft was performed...

Veins are often subjected to torsion and twisted veins can hinder and disrupt normal blood flow but their mechanical behavior under torsion is poorly understood. The objective of this study was to investigate the twist deformation and buckling behavior of veins under torsion. Twist buckling tests were performed on porcine internal jugular veins (IJVs) and human great saphenous veins (GSVs) at various axial stretch ratio and lumen pressure conditions to determine their critical buckling torques and critical buckling twist angles...

BACKGROUND: The autologous saphenous vein is the most common conduit for coronary artery bypass grafting, but the vein graft disease will occur. This study used Matrigel basement membrane matrix with many different growth factors to promote vasa vasorum neovascularization and extenuate the hypoxia to improve remodeling. METHODS: This study observed the hypoxia and thickness of the vein grafts at different times. Normal veins and vein grafts with 15 min of ischemia one day postoperatively were harvested in the neck of rabbits...

BACKGROUND: Percutaneous coronary intervention (PCI) of saphenous vein grafts (SVGs) has historically been associated with a high risk of adverse ischemic events, but there is a paucity of contemporary data on the second-generation drug-eluting stent use within SVG, and the relative importance of high platelet reactivity (HPR) in SVG PCI versus native lesion PCI is unknown. We studied ischemic and bleeding events after SVG PCI and their association with HPR. METHODS AND RESULTS: Subjects in the prospective, multicenter ADAPT-DES study (Assessment of Dual Antiplatelet Therapy With Drug-Eluting Stents) were stratified according to whether they had PCI of an SVG or a non-SVG lesion...

OBJECTIVES: Endoscopic vein harvest for lower extremity arterial bypass grafting has been questioned due to concern for endothelial damage during procurement. We sought to compare Nitric Oxide (NO)-mediated endothelial dependent relaxation (EDR) in vein segments harvested using open surgical (OH) versus endoscopic (EH) techniques. METHODS: Saphenous vein segments were harvested for lower extremity bypass, and a single, minimally handled section of saphenous vein, free of branches, was taken from the end of the graft...

BACKGROUND: Inguinal lymph node dissection (LND) is a surgical procedure with a high morbidity rate. Variations in surgical procedure, such as sparing of the saphenous vein, have been proposed to reduce surgical morbidity. While sparing of the saphenous vein has shown promising results in earlier studies, data for this procedure in melanoma patients are rare. In this retrospective study, we report 10-year findings on the effects of saphenous vein-sparing LND on surgical morbidity and oncologic outcomes in melanoma patients...

Takayasu arteritis is a disease that results in the granulomatous inflammation of large vessel walls. Takayasu arteritis is generally observed in young females during the second or third decades of life. This disease is treated by the revascularization of the affected organs either by surgery or by endovascular interventions. In this study, we present a case where renal autotransplantation was performed on a lady with an autologous saphenous vein graft subsequent to numerous previous endovascular interventions for her solitary kidney due to Takayasu arteritis-induced renal artery stenosis...

Chronic venous disease is a common disorder associated with a variety of symptoms in later disease stages but also with complications such as venous leg ulcer. This, in turn, has substantial socioeconomic effects and significantly impacts patients' quality of life. While there are a number of diagnostic procedures available, color-flow duplex ultrasound has become the gold standard. As regards therapeutic options, major advances have been made in recent decades. Today, there are alternatives to saphenofemoral ligation and stripping of the great saphenous vein, including endovenous thermal ablation techniques...

INTRODUCTION: Outcomes disparities associated with lower extremity bypass (LEB) for peripheral arterial disease (PAD) have been identified but are poorly understood. Marital status may affect outcomes through factors related to health risk behaviors, adherence, and access to care but has not been characterized as a predictor of surgical outcomes and is often omitted from administrative datasets. We evaluated associations between marital status and vein graft patency following LEB using multivariable models adjusting for established risk factors...
