BACKGROUND The long-term results of coronary artery bypass surgery depend mostly on the type of the grafts. For a long time, it has been accepted that arterial grafts are superior to venous grafts. In this study, we evaluated the angiographic patency rates of arterial and venous grafts. METHODS The study took place between 2003 and 2013 in the Departments of Cardiovascular Surgery in Baskent ...

Background/Aim. Although distal venous patch and cuff techniques are recommended to improve the patency of by-pass in lower extremities, advantage these remains unproven. Autovenous bypass graft method choice, but when there is no possibility using great saphenous vein, may have an advantage. The aim this study was evaluate results femorodistal procedures with a critical extremity ischemia. Met...

AIM To evaluate portal vein (PV) stenosis and stent patency after hepatobiliary and pancreatic surgery, using abdominal computed tomography (CT). METHODS Percutaneous portal venous stenting was attempted in 22 patients with significant PV stenosis (> 50%) - after hepatobiliary or pancreatic surgery - diagnosed by abdominal CT. Stents were placed in various stenotic lesions after percutaneous ...

BACKGROUND Patients who have Stanford type A aortic dissection with impaired coronary arteries or who have aneurysms from the ascending aorta to the aortic arch with coronary artery disease need coronary artery bypass grafting (CABG) with tube graft replacement of the ascending aorta simultaneously. When vein grafts are used for CABG in these patients, the proximal anastomoses of vein grafts ar...

Objective: Due to the potential of thrombus blockage and aneurysm rupture, saphenous veins with varicose are not advised for use as bypass grafts. However, if no other autologous vein is accessible a conduit in lower-limb bypass; transplants may be employed. Few reports have studied clinical results using We therefore investigated whether or acceptable patency rates graft could achieved.

The purpose of the present study was to examine whether patency times, including complications of subcutaneous venous chest port insertion using ultrasonography (US) guidance, differ between jugular and subclavian venous access. Between December 2008 and July 2010, subcutaneous venous chest ports were placed in 347 patients by an experienced team. All single-lumen port catheters were placed int...

OBJECTIVE The Symmetrytrade mark aortic connector creates proximal anastomoses of saphenous vein grafts using a nitinol implant. The device avoids partial clamping and thus possibly reduces neurologic complications. To evaluate graft patency, a single surgeon randomised study was performed in our institution. METHODS Seventy-seven patients were randomised either to automated proximal anastomo...

OBJECTIVE Deep venous stenting has become the primary treatment option for chronic venous obstructive disease, both for iliac vein compression and post-thrombotic venous lesions. Until recently, only stents aimed at arterial pathology were used, because no dedicated venous stents were available. However, three such stents have now become available. These venous stents are characterized by incre...
