Long-term follow-up data from several leading centers concerning patients undergoing coronary artery bypass clearly demonstrate the superiority of the internal mammary artery (IMA) with patency rates of 83 to 94% at 7 to 12 years compared with the saphenous vein and its patency rates of 41 to 53%. Our experimental studies provide a biological basis for(More)
BACKGROUND Out of all peripheral arterial aneurysms, 70% are located in the popliteal artery; less than 4% of these rupture. Ruptured popliteal aneurysms may be mistaken for deep venous thrombosis. MATERIAL AND METHODS From March until June 2001 three patients were primarily admitted with a diagnosis of venous thrombosis. This delayed the appropriate(More)
We have examined the clinical results of 56 externally-supported (EXS) Dacron grafts in the axillofemoral position and 117 in the femoropopliteal position. Results have been analyzed from two perspectives: primary patency concerns only those grafts that had never occluded; extended patency refers to all open grafts including those whose continued patency is(More)
PURPOSE To assess the rate of complications associated with the fascia closure technique for femoral access sites in which 18-F or 20-F sheaths were introduced during endovascular aneurysm repair (EVAR). METHODS A retrospective analysis was done of 50 consecutive patients (41 men; median age 75 years, range 62-85) who received Excluder stent-grafts in(More)
Carvedilol is an alpha1 and nonselective beta-adrenergic receptor antagonist with antioxidative properties known to protect against reperfusion injury in the heart, brain, and kidneys. The aim of this study was to test the hypothesis that carvedilol improves postischaemic reperfusion and tissue survival in skeletal muscle. Sixteen Wistar rats underwent(More)
The influence on healing of three materials for closure of interstices in a macroporous Dacron arterial prosthesis were evaluated by 56-day implantation in the canine descending thoracic aorta. The materials studied were: the nondenatured fibrin deposited as a result of a 4-step preclot with autogeneic blood (n = 6), heat-coagulated autogeneic blood(More)
OBJECTIVE/BACKGROUND The objective was to observe for 1 year all patients in Norway operated on for symptomatic carotid stenosis with respect to (i) the time from the index event to surgery and neurological events during this time; (ii) the level in the healthcare system causing delay of surgical treatment; and (iii) the possible relationship between(More)
This study was designed to establish the influence of the recipient's thrombotic potential on the patency of small-caliber prostheses and to evaluate the subsequent improvement of graft performance by medicinally altering the prostaglandin balance in subjects predisposed to graft occlusion. Mongrel dogs were pretested and classified as low and high(More)
The study objective was to determine the optimal water porosity for a warp-knit, externally veloured Dacron arterial prosthesis. Preclotting efficiency, surgical handling characteristics, thrombogenicity, and 56-day healing in the descending thoracic aorta of mongrel dogs were measured for seven different arterial prostheses of the same basic design(More)
