Detailed knowledge of the vascular anatomy is important for improving surgical approaches to the liver. Twelve canine livers were skeletonized to describe the anatomy of their portal and hepatic veins in details. Our data suggest that the liver can be divided into two sections, three divisions, seven lobes and two to four sub-lobes. This differs from the(More)
Although the exposure of human subjects to prostacyclin (PGI2) infusion has been broad, no systematic approaches have been made in order to investigate the dose-related side effects in patients with angina pectoris and coronary artery disease (CAD). We studied 25 patients with typical chest pain and overt CAD. All patients underwent a cycloergometer stress(More)
The aim of the present study was to assess the incidence of myocardial ischemia during cold pressor test in patients with stable exertional angina pectoris. Thirty-seven patients with proven coronary artery disease were submitted to cold pressor and exercise stress testing; computer assisted electrocardiographic recordings were obtained throughout the(More)
Patients with coronary artery disease exhibit a reduced coronary vasodilator reserve in response to exercise testing. Drugs which block coronary beta adrenergic receptors could exacerbate this abnormality leaving the vasoconstrictor alpha tone unopposed and/or counteracting the beta 2-mediated vasodilation elicited by the increase in myocardial oxygen(More)
Purpose. To verify the influence of neural mobilization (NM) applied to the lower limbs on functional performance and dynamic balance in asymptomatic individuals. Methods. The total of 30 asymptomatic participants (15 women and 15 men; age, 30.1 ± 6.7 years; height, 1.70 ± 0.1 m; body mass, 73.1 ± 13.4 kg) were enrolled in this cross-over randomized(More)
Vasodilators of resistive vessels may induce ischemia in patients with coronary artery disease. To evaluate this possibility during prostacyclin (PGI2; scalar doses up to 10 ng/kg/min) and prostacyclin analog (iloprost; scalar doses up to 6 ng/kg/min) infusions, we studied 33 patients with angina pectoris and proved coronary artery disease. Patients were(More)
The effects of iloprost, a chemically stable compound with prostacyclin mimetic activity, on exercise capacity and platelet aggregation were assessed in 24 patients with effort angina and proved critical (at least 70% diameter narrowing) coronary artery disease. Upright bicycle ergometer testing (25-W increments every 2 minutes) was performed during drug(More)
