BACKGROUND Graft patency is a fundamental predictor of long-term survival after coronary artery bypass surgery. Left and right internal thoracic artery (arterial) graft patency has been shown to be superior to that of saphenous vein grafts. More recently, the radial artery has been used as an aortocoronary graft, but little is known about the midterm and long-term patency of this conduit. We pe...

BACKGROUND Tubal occlusion is one of the most frequent causes of infertility in women. The evaluation of the fallopian tube is necessary to determine the management plan for infertility. The two most important diagnostic procedures which are used for the evaluation of tubal patency are hysterosalpingography (HSG) and laparoscopy. OBJECTIVES The aim of this study was to compare HSG and laparos...

BACKGROUND Patients undergoing percutaneous recanalization of chronically occluded superficial femoral arteries were studied to determine which factors correlated with 1-year patency. Immediate change in ankle:brachial index (ABI), length of occlusion, tibial run-off, and the performance of supplemental catheter atherectomy were evaluated. METHODS Eligible patients had at least one patient ti...

PURPOSE To compare the effectiveness and patency of the TearLeader stent (PBN) for treatment of lacrimal system obstruction. METHODS A prospective study of 68 patients referred from the ophthalmology department with suspicion of lacrimal system obstruction. We placed 74 TearLeader PBN stents. Inclusion criteria were: complete obstruction of lacrimal duct with canalicula and lacrimal puncta pa...

 Abstract Background: The optimal therapy of acute iliofemoral venous thrombosis is still a matter of debate. The purpose of our study was to evaluate the late results of iliofemoral thrombectomy with regard to the prevention of the development of a Post Thrombotic Syndrome (PTS). Methods: During 2000-2003, 18 patients underwent transfemoral venous thrombectomy for acute iliofemoral venous thro...

OBJECTIVE To investigate the value of intraoperative blood flow measurements on early and long-term patency of above-knee prosthetic femoropopliteal bypass. METHODS Flow was measured with a transit time flowmeter before (basal flow) and after an intragraft injection of papaverine (papaverine flow) in 87 operations (86 patients) between January 1990 and December 2001. Sixty-one grafts were of ...

BACKGROUND Long-term patency of extracranial-to-intracranial (EC-IC) vein bypass is poorly understood. OBJECTIVE We report our experience of patency of arterial pedicle grafts and interposition vein grafts for the purpose of EC-IC bypass. METHODS We analyzed 294 consecutive patients who underwent 178 intracranial arterial pedicle bypass procedures and 152 intracranial vein bypass procedures...

BACKGROUND Mature autogenous arteriovenous fistulas have better long term patency and require fewer secondary interventions compared to arteriovenous prosthetic graft. Our Study evaluated vascular patency rates and incidence of interventions in autogenous arteriovenous fistulas and grafts. MATERIAL AND METHODS A total of 166 vascular access operations were performed in 153 patients between De...

Mats Dreifaldt (2013): Conduits in coronary artery bypass grafting surgery: Saphenous vein, radial and internal thoracic arteries. Örebro Studies in Medicine 93. A novel technique for saphenous vein (SV) graft harvesting, the No-touch technique (NT), has been developed at the Dept. of Cardiovascular surgery, Örebro University hospital. With NT the SV is harvested with a pedicle of surrounding t...
