Isolated Femoral Nerve Neuropathy After Intra-aortic Balloon Pump Treatment

Intra-aortic balloon pump (IABP)-related neuropathy is an infrequent complication, and the development of motor deficits is even rarer in such cases. We report a 37-year-old man with anterior ST-elevation myocardial infarction who received emergent percutaneous coronary intervention and IABP counterpulsation. Weakness and numbness developed after IABP removal despite lack of evidence of ischemia in the involved extremity. Nerve conduction velocity study and electromyogram led to the diagnosis of femoral nerve neuropathy. The neurologic deficits recovered after 6 months of rehabilitation. This case illustrates the importance of bedside neurologic examination of the involved extremity for early detection of possible injury to the femoral nerve in patients after IABP treatment and insertion of larger bore catheter.
