BACKGROUND Two novel approaches to implanting a central venous catheter port in non-human primates (NHPs) using peripheral insertion are presented and compared. METHODS Sixty vascular access port (VAP) implants were attempted in 52 NHPs by saphenous vein puncture (n = 20) or saphenous vein cutdown (n = 40). RESULTS Fifty eight procedures were successful. Eighteen of 20 VAPs were successfull...

CONTEXT Various techniques for reconstruction after superior mesenteric-splenic-portal vein confluence resection during pancreaticoduodenectomy have been introduced. A certain kind of vascular grafting may be necessary especially when long segmental resection of superior mesenteric-splenic-portal vein confluence is required. CASE REPORT We herein report the cases of two patients who underwent...

OBJECTIVE This study aims to evaluate the impact of CO(2) venography on the planning and outcome of native arteriovenous fistula (AVF) creation. METHODS Records of patients who underwent CO(2) venography prior to access surgery between January 2000 and December 2008 were reviewed. CO(2) venography was performed selectively in chronic kidney disease (CKD) in stage IV-V patients without suitabl...

Coronary artery bypass grafting (CABG) was first used in the late 1960s. This revolutionary procedure created hope among ischemic heart disease patients. Multiple conduits are used and the golden standard is the left internal mammary artery to the left anterior descending artery. Although all approaches were advocated by doctors, the use of saphenous vein grafts became the leading approach used...

Despite carefully performed surgery, vascular defects can remain undetected within an arterial reconstruction after blood flow is restored. Failure to recognize technical errors or abnormalities can lead to vessel thrombosis and embolization. For cardiac, carotid or visceral reconstructions these events can be catastrophic. Furthermore, corrections of lesions before graft thrombosis can have a ...

In the absence of autogenous vein, cryopreserved greater saphenous vein is an acceptable alternative conduit for lower extremity bypass. This study compares outcomes veins (CVs), and two-segment spliced (SVs) infrageniculate revascularization. A retrospective review all bypass with CV or SV was conducted between 2010 2022. Primary included limb salvage major adverse events. Secondary primary, p...

BACKGROUND The aim of the present study was to assess the long-term graft patency rate of the radial artery (RA), in comparison to the saphenous vein (SV) in patients harvested for both vessels. METHODS AND RESULTS RA and SV were concomitantly used for coronary artery bypass grafting in 318 patients in an 8-year period from January 2002 to March 2010. During follow-up, graft patency was asses...
