Major complications of angioaccess surgery.

Angioaccess procedures at one institution over a 4-year period were retrospectively reviewed to ascertain the frequency of major limb- or life-threatening complications. A total of 435 angioaccess procedures were performed, including 81 Cimino-Brescia fistulas, 166 polytetrafluoroethylene grafts, and 111 thrombectomy/revisions. There were 77 operations for major complications in 53 patients. In addition, five patients required major vascular repair or emergency thoracotomy for complications of central hemodialysis line placement. A significant portion (18% of this series) of the total angioaccess caseload of a vascular surgeon will be utilized in the repair of major complications. The in-hospital (6 patients, or 11%) and long-term (12 patients, or 23%) mortality rates are significant. Although most complications can be repaired without limb loss and with shunt salvage, a small percentage (in our study three patients, or 4%) will have debilitating long-term symptoms.
