An evaluation of ultrasonography in early dilatation and aneurysm is presented. Fifty-nine patients with prominent abdominal pulsation were examined and aneurysm was demonstrated in 22. There was a high degree of correlation between the size of the aneurysm demonstrated by ultrasound and the size displayed at operation. It was also possible to demonstrate(More)
Stent migration into the right atrium is a potentially fatal complication of stenting in the venous system and is most likely to occur during the treatment of superior vena cava obstruction. Endovascular approaches that can salvage this hazardous situation are described and the keys to successful treatment are highlighted. Four different strategies are(More)
PURPOSE To determine the feasibility of diagnosing deep venous thrombosis (DVT) with direct three-dimensional magnetic resonance (MR) imaging of the thrombus. MATERIALS AND METHODS Eighteen patients with proved DVT at conventional venography were evaluated with a magnetization-prepared three-dimensional blood- and fat-suppressed MR imaging sequence. The(More)
The hazards of dealing with infected false femoral aneurysms resulting from intra-arterial narcotic injection are highlighted in six patients. Two patients were human immunodeficiency virus positive and three patients were hepatitis B surface antigen positive. Because of these infections exploration of groin swellings as presumed soft tissue abscesses is(More)
OBJECTIVES To study the value of a number of proposed prognostic factors in prediction of the risk of perioperative cardiac events after vascular surgery. DESIGN AND METHODS Two hundred and ninety-seven patients undergoing peripheral vascular surgery were prospectively studied. Patients underwent preoperative 24 h ambulatory electrocardiography,(More)
Fifty minor foot and transmetatarsal amputations were studied to assess the reliability of Doppler ankle blood pressure (DABP) and skin blood flow (SBF) to predict healing. The level of amputation was determined solely on clinical criteria. Thirty-six (72 per cent) of the amputations healed. There was no statistical difference between mean DABP in healed 89(More)
A 96 h infusion of epoprostenol (prostacyclin) or placebo was given as a treatment for rest pain to 28 patients with severe peripheral arterial disease. 24 h after the end of the infusion patients given epoprostenol had significantly less pain and took fewer analgesics tablets than did the controls. In some patients the epoprostenol effect lasted for over 1(More)
PURPOSE To classify and analyze the volumetric changes seen on spiral computed tomographic angiography (CTA) following endovascular abdominal aortic aneurysm (AAA) repair. METHODS Fifty patients (46 men; mean age 71 years, range 51-83) with >1 year of imaging follow-up were retrospectively selected. The volume of the aneurysm sac was calculated on(More)
We investigated the relationships between the angiographic severity of peripheral arterial occlusive disease (PAOD) and haemostasis, fibrinolytic, and rheological variables in 219 patients with symptomatic peripheral arterial occlusive disease (PAOD). White cell count, fibrinogen, cross-linked fibrin degradation products (FDP), von Willebrand factor, and(More)
