Objective

Background BACKGROUND: The proximity of femoral nerve to femoral artery renders it vulnerable to injury during transfemoral percutaneous catheterization procedures.

Design/Methods DESIGN/METHODS: We analyzed the data from Nationwide Inpatient Sample release annually. We pooled the data from 2002 through 2010 and identified patients using the ICD 9 CM procedures codes who underwent transfemoral percutaneous catheterization procedures. We subsequently identified occurrence of femoral nerve injury in this cohort of patients. Baseline characteristics, co-morbid conditions, in hospital complications and discharge outcomes (mortality, minimal disability, and moderate to severe disability) were compared between the two groups.

Results RESULTS: Of the 14255031 patients who underwent percutaneous catheterization procedures, 508 (3 per 1000 procedures) developed femoral nerve injury. The incidence of femoral nerve injury was higher in women: 57% vs 39%%, p <0.004. Patients with coexisting congestive cardiac failure or coagulopathy had a non-significantly increased incidence of femoral nerve injury. There was no in-hospital mortality among patients who developed femoral nerve injury; however, the rate of discharge to nursing facility was higher in patients with femoral nerve injury: 19% vs 10%, p <0.001. After adjusting for age, gender , presence of congestive cardiac failure and coagulopathy femoral nerve injury during percutaneous catheterization procedures was independently associated with moderate to severe disability at discharge (Odds ratio, 2.3; 95% confidence interval, 1.4-3.8, p <0.001).

Conclusions CONCLUSIONS: Femoral nerve injury is a rare complication during percutaneous catheterization procedures which may increase the likelihood of moderate to severe disability at discharge.
