Delayed femoral pseudoaneurysm formation after percutaneous coronary intervention.

Five femoral pseudoaneurysms were treated among 573 patients who underwent percutaneous coronary interventions. Four of the five patients suffered from diabetes mellitus and four patients needed regular hemodialysis due to chronic renal failure. One patient's course was complicated by infection. One patient was healed by compression therapy and four patients were treated successfully by surgery, which included an extraanatomic bypass and a thromboendoarterectomy. Diabetes and regular hemodialysis are major risks for the formation of femoral pseudoaneurysm after catheter intervention at present.
