Maintaining hemodialysis vascular access is an essential requirement for effective hemodialysis. If the hemodialysis vascular is not secured, patient's life cannot be maintained due to the blood vessel is blocked by the thrombus. It is a rule in Hemodialysis Vascular Access Center of Ewha Womans University Mokdong Hospital, whose emergency phone number (02-2650-2598) runs 24-7, to perform the procedure by two teams consisting of an interventional procedure specialist and a vascular surgeon on the same day of patients visit when a stenosis or thrombosis occur in a hemodialysis patient's hemodialysis vascular access. Our goal is to maximize patient comfort and provide the best medical care by allowing one visit to the hospital to completely resolve the hemodialysis vascular problem.
