Complications related to @entity661 pumping (IABP) remain a problem despite the development of small caliber balloon catheter shafts and introducer sheaths. The authors report their experience in counterpulsation-related complications of 201 consecutive @entity1 who underwent 212 percutaneous counterpulsation balloon insertions from June 1989 to June 1996 by use of balloons with 8-9.5 French shafts. Of these, 82% were @entity1 and 36 (18%) were @entity1 , with a mean age of 61 +/-12 years. Indications for counterpulsation were @entity583 ( @entity583 ) (67%), severe @entity1002 without @entity583 (20%), @entity384 (4%), @entity1459 (3%), high-risk supported percutaneous coronary angioplasty (2%), and others (4%). IABP was instituted at the bedside in the intensive care unit in 82 @entity1 (39%) and in the catheterization laboratory in 130 (61%). Median duration of counterpulsation was 48 hours (range 30 minutes to 25 days) with successful weaning from counterpulsation in 70% (148 of 212) of procedures. Overall in-hospital mortality rate was 45% (90 of 201). The overall complication rate was 22/212 (10.4%). Major complications were present in 10/212 procedures (4.7%): 6 @entity1 with @entity63 (1 death directly attributed to this complication, 1 with associated @entity295 and limb amputation, 3 requiring surgical thromboembolectomy, and 1 with persistent @entity63 treated medically until his death caused by intractable @entity1002 ), 2 with important @entity548 (1 fatal despite vascular surgical repair and 1 requiring blood transfusion) and 2 with @entity397 requiring vascular surgery. Minor complications were present in 12 procedures (5.7%), 6 with @entity63 , 3 with @entity548 , and 3 with @entity409 . All of these resolved after balloon removal and required no further intervention. When @entity63 did develop it occurred after a median delay of 24 hours following balloon insertion (range 2 to 98 hours). The only predictor of @entity63 among baseline clinical and procedure-related variables was an age greater than 60 years. Compared with previous recent studies, the rate of complications observed in this study performed with small balloon catheters was acceptably low. @entity63 was the most frequent complication, often occurred early, and required further intervention in half the cases.
