Epub 2017 Jul 6. with angioplasty (using a balloon to open the blockage), and stenting The failure of treatment to completely abolish the stenoses appeared to be a marker of ongoing symptoms. Venous thrombosis and stenosis after peripherally inserted central catheter placement in children. Patients may also develop swelling of the face or neck. is a dialysis access in the arm on the same side. lar management of the central venous stenosis or obstruction in hemodialysis patients. Excessive alarms (high or low venous pressure alarms) on the dialysis machine due to access flow issues through the access during dialysis sessions. veins can often be opened, rapidly and markedly reducing swelling. CT scan is better but unreliable. Am J Kidney Dis. A significant venous outflow stenosis appeared to be a risk factor for the failure of conservative treatment, with 10/12 or 83% of treated children having a stenosis greater than 65%. The key to reducing the prevalence of CVS is in reducing CVC placement and placement of arteriovenous accesses prior to initiating dialysis. When an AV fistula is created, a connection is made between a high-pressure arterial system and a low-pressure venous system. The trauma and inflammation related to the catheter placement is thought to result in microthrombi formation, intimal hyperplasia … Pediatr Radiol.

Background: The most common cause of graft failure in patients undergoing hemodialysis is outflow venous stenosis. Timely vein mapping and referral to the surgeon for fistula creation can obviate the need for a CVC and decrease incidence of CVS.
