Background: Failure of arteriovenous fistulas (AVFs) to meet the minimum requirements for hemodialysis (HD) is the greatest cause of morbidity in patients on renal replacement therapy. Identifying risk factors associated with failure of vascular access is crucial to management and success of hemodialysis treatment. Objective: To compare mean duration of(More)
Background: Critical lower limb ischemia in the absence of a distal arterial bed can be treated by arterialization of the venous arch of the foot. Objetive: The objective of this paper was to present the technique and the results of the arterialization of the venous arch of the foot with the in situ great saphenous vein.

PURPOSE To investigate the potential protective effect of allopurinol on reperfusion injury by determining the inflammatory response through the measurement of tumor necrosis factor-alpha (TNF-alpha). METHODS Sixty rats were distributed into two groups: control and allopurinol and each group was divided into three subgroups, ischemia for two hours,(More)
PURPOSE To analyze the effects of allopurinol and of post-conditioning on lung injuries induced by lower-limb ischemia and reperfusion. METHODS Thirty rats were used. They were divided in 5 groups: (1) group A: abdominal aortic dissection only, (2) group B: ischemia and reperfusion, (3) group C: administered allopurinol (100mg/Kg) a few hours before(More)
