title: [Complications of vascular access for hemodialysis - limits, imagination and commitment].
abstract: Terminal chronic kidney disease courses with high mortality and is a serious public health problem on a global scale. In Portugal, it involves about 14,000 patients of whom 5,000 are transplanted. The remaining require permanent renal replacement techniques. Every year, there are 2,200 new cases and the mortality rate is around 20%. One of the most important determinants for the survival of hemodialysis patients is the quality of vascular access. The role of the vascular surgeon is to planify and to do the best access possible, monitoring and fight for its patency and thereby improve not only the quality of life but also to combat mortality associated with complications of vascular access - first cause of hospital admission of these patients. The authors report 10 clinical cases in which the limits of the hemodialysis surgery were tested and where it was necessary commitment and imagination to prevent the vascular access loss. The management of some complications is a challenge for the vascular surgeon and currently it is necessary to find hybrid/complementary solutions. Examples of some complications and challenges are steal syndromes, venous hypertension, vascular access in unusual places and 'total' failure of vascular access. Focusing on maintaining vascular access working improves the quality of dialysis, quality of life for patients, saves vascular capital for future access and in extreme cases, saves lifes.
