Incidence of vascular complications in intraaortic balloon counterpulsation is still high despite major refinements in catheter design and techniques. One hundred twenty-six patients in whom intraaortic balloon pumping was attempted were divided into two groups on the basis of insertion technique. Group 1 included 77 patients in whom the conventional percutaneous insertion was used. In group 2 (n = 45 patients), a sheathless insertion technique was used. The overall vascular complication rate was 19.6%, with the lower limb ischemia as the most common complication. The vascular complication rate was 25.9%, in group 1 and 8.8% in group 2 (p < 0.01). Lower limb ischemia was noted in 17 patients in group 1 and 3 patients in group 2 (p < 0.01). These results suggest that sheathless insertion of the intraaortic balloon pump catheter can minimize vascular complications. This technique will be especially useful in patients with peripheral vascular disease, in whom the likelihood of vascular complications is high. © 1993.
