The most important complications of fistulae for HD are lymphedema, infection, aneurysm, stenosis, congestive heart failure, steal syndrome, ischemic neuropathy and thrombosis. In HD patients, the most common cause of vascular access failure is neointimal hyperplasia.
Fistulas may also form between the gut and the skin or between the gut and an abscess cavity. Rarely, fistulas arise between a vessel and the gut, resulting in profound GI bleeding, which is a surgical emergency. (See Etiology.) Most GI fistulas (75-85%) occur as a complication of abdominal surgery. However, 15-25% of fistulas evolve spontaneously and are usually the result of intra-abdominal inflammation or infection. Regardless of their cause, fistulas have a tremendous impact on patients and society.
