OBJECTIVE To describe and test a practical protocol to measure common carotid intima-media thickness that uses the combined values of two longitudinal examination angles to increase sensitivity. METHOD Between February and September 2005, 206 patients underwent duplex scan examination of carotid vessels, and the intima-media thickness of 407 common(More)
The presence of femoral vein (FV) duplicity has potential influence in the misdiagnosis of deep vein thrombosis. Also, FVs are suitable vascular substitutes, especially in the substitution of infected prosthetic grafts. The objective of this study was to describe the prevalence, anatomic patterns and characteristics of FV duplicity in adult individuals by(More)
Acute ischemia due to spontaneous dissections of the superior mesenteric artery are uncommon events, with sporadic reports. Therapeutic options include clinical management, direct artery repair, bowel resection, and more recently, endovascular stenting. We present a case of abdominal pain due to superior mesenteric artery spontaneous isolated dissection(More)
OBJECTIVE To compare the results of percutaneous transluminal angioplasty (PTA) and bypass graft surgery (BGS) for the treatment of infrapopliteal lesions in individuals presenting with critical limb ischemia (CLI). METHOD A total of 48 infrapopliteal PTAs and 50 infrapopliteal BGS were compared retrospectively. All grafts used nonreversed saphenous vein(More)
OBJECTIVE To compare common carotid intima-media thickness (IMT) between the two major Brazilian ethnic groups (those of African descent and those of European descent) among individuals with one or more risk factors for atherosclerotic disease. METHOD Two hundred and six patients with one or more risk factors for atherosclerotic disease were evaluated in(More)
We compared the prevalence of risk factors between young and old individuals with significant carotid atherosclerosis. We retrospectively reviewed the records of patients aged 39 to 55 years (group I) and aged ≥ 60 years (group II) with significant atherosclerotic stenosis at the carotid bifurcation. Group I patients had significantly higher values for the(More)
The therapeutic management of venous thromboembolism (VTE) is rapidly evolving. Following the positive results of pivotal large-scale randomised trials, the non-vitamin K antagonist oral anticoagulants (NOACs) represent an important alternative to standard anticoagulation. In phase III studies, dabigatran was as effective as, and significantly safer than(More)
OBJECTIVE To report our experience of long-term results of inframalleolar bypass. DESIGN Retrospective analysis. MATERIALS AND METHODS We analysed 122 inframalleolar bypasses performed between January 1991 and June 2005 in 116 patients. Most patients were treated for critical ischaemia (97%). The indication for the use of podalic arteries was a lack of(More)
The incidence of bilateral deep venous thrombosis in patients with single limb or bilateral symptoms was determined using duplex scan examination. In a prospective study, 157 inpatients with clinical suspicion of deep venous thrombosis underwent duplex scan evaluation of the lower extremities. Demographic characteristics, physical examination data, and risk(More)
OBJECTIVE Predicting cardiac events is essential to provide patients with the best medical care and to assess the risk-benefit ratio of surgical procedures. The aim of our study was to evaluate the performance of the Revised Cardiac Risk Index (Lee) and the Vascular Study Group of New England Cardiac Risk Index (VSG) scores for the prediction of major(More)
