| Abstract: | Infection of the femoral artery (endarteritis) complicating intraaortic balloon pumping has not been reported. Most reports of complications with this pump have not emphasized wound infection. Whether the balloon is inserted by open or percutaneous technique, infection remains a problem. During the past 7 years, 32 of 50 patients (64 percent) who had intraaortic balloon pump insertion survived balloon removal. In four patients, wound infection of the groin developed with involvement of the femoral artery. Sepsis was due to P. aeruginosa in three patients and E. cloacae in one. All patients required variable degrees of resection of the infected femoral artery wall. One had successful arterial reconstruction with vein patch angioplasty alone after debridement of the vessel wall. In a second patient, resection of the common femoral artery with interposition of a saphenous vein that had been reconstructed to enhance its diameter to that of the femoral artery was accomplished. Dehiscence of a vein patch angioplasty occurred in the remaining two patients with resultant hemorrhage. Further resection of the femoral artery was required with femoro-femoral saphenous vein grafting in one patient and iliofemoral vein grafting in another. Tissue coverage of the reconstructed vessel was best accomplished using a tensor fascis lata myocutaneous flap. All patients survived the infection without amputation. |
