Femoral access site complications following neurointerventional procedures: economic implications at a single center.

Abstract

Transfemoral access (TFA) has been the traditional route of arterial access for neurointerventional procedures. Femoral access site complications may occur in 2%-6% of patients. Management of these complications often requires additional diagnostic tests or interventions, each of which may increase the cost of care. The economic impact of a femoral access site complication has not yet been described. The objective of this study was to evaluate the economic consequences of femoral access site complications. The authors conducted a retrospective review of patients undergoing neuroendovascular procedures at their institute and identified those who experienced femoral access site complications. The subset of patients experiencing these complications during elective procedures was matched in a 1:2 fashion to a control group undergoing similar procedures and not experiencing an access site complication. Femoral access site complications were identified in 77 patients (4.3%) over a 3-year period. Thirty-four of these complications were considered major, requiring blood transfusion or additional invasive treatment. There was a statistically significant difference in total cost ($39,234.84 vs $23,535.32, p = 0.001), total reimbursement ($35,500.24 vs $24,861.71, p = 0.020) and reimbursement minus cost (-$3734.60 vs $1326.39, p = 0.011) between the complication and control cohorts in elective procedures, respectively. Although occurring relatively infrequently, femoral artery access site complications increase the cost of care for patients undergoing neurointerventional procedures; how this influences the cost effectiveness of neurointerventional procedures warrants further investigation.
