Vascular complications following intra-aortic balloon pump insertion.
The 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. ⋯ 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.

Significant external forces are required to fracture a normal pelvis. These forces usually result from rapid deceleration or crushing injuries, and energy often is delivered to multiple anatomic sites in addition to the pelvis. Associated injuries are common, and numerous complications can occur in patients with pelvic fractures. ⋯ Patients with complications had higher Injury Severity Scores, lower Trauma Scores, increased transfusion requirements, longer hospital stays, and greater hospital charges compared to those without complications (P less than 0.01 for all variables). There was no association of complications with patient age, sex, mechanism of injury, anatomic site or amount of displacement of the pelvic fracture, or vector of injury. Patients with unstable pelvic fractures were much more likely to have complications than were those with stable pelvic fractures (P = 0.013).(ABSTRACT TRUNCATED AT 250 WORDS)
