ObjectiveThe purpose of our study is to compare the results of the sheathed and sheathless techniques for intraaortic balloon pump (IABP) insertion and to determine the rate of vascular complications in both conditions.MethodsA total of 1211 patients were examined representing a period of 19 years. Three hundred five sheathless (Group I) and 906 sheathed (Group II) IABP catheters were evaluated retrospectively. Data were analyzed with univariate analysis and logistic regression. Relative risk (RR) values were calculated in order to examine the effect of sheath.ResultsLimb ischemia was seen in 129 patients (10.9%). Although the incidence of peripheral arterial disease (PAD) was relatively higher in Group I (11.1% vs. 3.6%), the ischemic complication rate was lower in Group I (5.2% vs. 12.4%; p = 0.001). Presence of PAD (p = 0.001) and diabetes mellitus (DM) (p = 0.007) was found to be the risk factors of ischemia related to IABP use in all cases. In logistic regression analysis, presence of PAD, DM, and sheathed method was found to be the risk factors of ischemia. The patients who had all of these risk factors suffered from limb ischemia (RR value: 35.17).ConclusionPAD, DM, and sheathed insertion technique are the major risk factors of ischemia during IABP use. Among all these risk factors, the only modifiable risk factor is the use of introducer sheath. With the presence of PAD and DM, the choice of sheathed method would increase the probability of ischemia almost 35 times. Sheathless method of insertion should be preferred in patients with DM and PAD.
