Slow or no-reflow phenomenon (SNR) complicates 10%-15% of cases of percutaneous intervention (PCI) in aortocoronary saphenous vein grafts (SVG). At present, there are no uniform, effective strategies to predict or prevent this common and potentially serious complication. The purpose of our study was to characterize variables correlated with the risk of SNR(More)
Household members of surgical cases of hydatidosis were screened for the disease in two high-risk districts in Central Tunisia. Seventy-four index cases were identified from the 1980-1984 surgical records of Sousse University Hospital. Household members over five years of age were tested by ELISA, and if positive by counterelectrophoresis (CEP) for(More)
We present two cases of recurrent cavernous hemangiomas of the extremities. These conditions were initially treated unsuccessfully with surgical resection. After recurrence, the hemangiomas were treated by percutaneous transcatheter embolization. To the best of our knowledge, this is the first case report of treatment of cavernous hemangioma involving the(More)
We tested the hypothesis that unloading the left ventricle just prior to reperfusion provides infarct size reduction compared with left ventricular (LV) unloading postreperfusion and reperfusion alone. Twenty-four mongrel dogs were subjected to 2 hr of left anterior descending artery occlusion and 4 hr of reperfusion. A transvalvular (TV) left ventricular(More)
OBJECTIVES The aim of this study was to test the hypothesis that after an acute myocardial infarction, endothelin-1 release with subsequent calcium overload is a mediator of myocardial reperfusion injury, which can be inhibited, in part, by left ventricular unloading immediately before reperfusion. We recently have reported that left ventricular unloading(More)
A population-based echotomographic (ECT) and serological survey of hydatidosis was carried out in a high risk community located in Central Tunisia. 1434 subjects over 5 years of age (93.3% of the population in this age range) underwent an abdominal echotomography (ECT) and a serological test (ELISA with confirmation by counterelectrophoresis). The ECT(More)
BACKGROUND The histological appearance of stenosis in de novo saphenous venous grafts (DNSVG) consists of diffuse atherosclerosis that contains blood elements, necrotic debris and limited fibrocollagenous tissue. The friable nature of these lesions complicates percutaneous intervention (PCI) procedures. On the other hand, in-stent restenosis (ISR) of SVG is(More)
Study of as homogeneous series as possible of 72 cases of gastrointestinal haemorrhage in patients with portal hypertension showed that the major cause of bleeding, accounting for almost 70% of cases, was ulceration of oesophageal varices. The presence at autopsy of haemorrhagic or necrotic lesions of the gastric mucosa is not felt to be a definite argument(More)
Analysis of the operative reports of hospitals in the central area of Tunisia allowed to define the epidemiology of echinococcosis in children and adolescents. Four hundred forty-three patients under 20 years of age were operated on between 1980 and 1985. In children less than 10 years of age, boys are more often concerned than girls, whereas prevalence in(More)
