Periodic hemodialysis requires the vascular access to be capable of functioning perfectly for a long time; therefore early diagnosis of the most common complications is very important. Fifty-four @entity1 in dialysis treatment for @entity454 ( @entity454 ) were examined over a six-year period for vascular access (VA) complications. Eighty vascular accesses were studied: 68 @entity2548 and 12 @entity2758 . The most frequent radiological investigation was phlebography, followed by arteriography by direct puncture of the humeral artery, and, in few cases only, by arteriography through femoral approach; the total number of radiographic examinations performed was 101. The most frequent complications were @entity715 (50%) and stenoses (21%); @entity439 , @entity2849 steals were observed in 11% of the cases. Findings prove complications to depend neither on the type of VA ( @entity292 , prosthesis) nor on its site (proximal, distal). In 50% of the cases angiography allowed a therapy to be adopted for VA recovery. Percutaneous transluminal angioplasty (PTA), performed on 3 @entity1 , failed. Thus, in the authors' opinion, angiography is the method of choice for the evaluation of VA pathology, and surgery is the most efficient treatment for complications. Despite failures, PTA represents a valid alternative in the treatment of stenoses in larger vessels and prostheses.
