AbstractThe intra-aortic balloon pump (IABP) has been used for 23 years to treat cardiogenic shock from various causes. A retrospective review was conducted to evaluate the morbidity, mortality, and risk factors associated with insertion of this device. Over a recent 3-year period, 415 such pumps were inserted either by percutaneous (323) or cut-down (92) technique in 404 patients. Indications for placement included intraoperative pump failure (46%), cardiac instability before coronary artery bypass grafting (28%), perioperative support (13%), cardiac transplantation (7%), and cardiogenic shock (6%). Noncardiac vascular complications occurred in 67 patients, 55 per cent of whom required surgical correction. Operative procedures included femoral artery thrombectomy, bypass grafting, fasciotomy, and amputation. Major risk factors for vascular complications included diminished or absent femoral pulses on initial examination, being a woman, and obesity. In patients with known peripheral vascular disease, the risk of a vascular complication was 17.9 per cent when a surgical cut-down technique was used to insert the IABP, and 38.9 per cent when a percutaneous insertion was performed. The mortality doubled in those patients who had a vascular complication as compared to those who did not (34% vs 17%). A more liberal use of an open surgical technique in those patients with peripheral vascular disease, obesity, and who are women may help to reduce complications after the insertion of the intra-aortic balloon pump.
