Abstract
Central venous catheters for hemodialysis play an important role in the treatment of acute renal failure, for immediate vascular access in cases of urgently needed hemodialysis in chronic renal failure or for patients having problems with their permanent vascular access ??? arteriovenous anastomosis or prothesis. Some kinds of central venous catheters are named ???permanent??? catheters, as they are surgically implanted up to v.v. cava superior and inferior to provide higher blood flow and can be used longer time ??? a number of months or years. Two types of risk are associated with vascular access devices: those occurring during or shortly after placement and delayed risks that occur simply because the device is in your body.The different positions of the venous catheters are related to different level of risks of complications what is shortly described in this brief review.
