Comparison of Postcatheterization Pseudoaneurysm between Brachial Access and Femoral Access.

Postcatheterization pseudoaneurysm is a serious complication following diagnostic or therapeutic catheterization. Because radial access is unsuitable in some situations, there is still a need to use femoral or brachial access for arterial catheterization. The aim of this study was to compare the incidence and clinical characteristics of pseudoaneurysm between brachial and femoral access. We identified patients who underwent arterial catheterization from our cardiac catheter records. A total of 5,990 cardiac catheter records and discharge summaries were reviewed, and 23 pseudoaneurysm cases were identified. Those pseudoaneurysm cases were divided into a brachial pseudoaneurysm group (n = 9) and a femoral pseudoaneurysm group (n = 14). The incidence of pseudoaneurysm was significantly higher in brachial access than in femoral access (odds ratio: 4.16, 95% confidence interval: 1.80-9.65; P < 0.001). Successful manual compression was frequently achieved in both the brachial (77.8%) and the femoral (92.9%) pseudoaneurysm groups (P = 0.295). Surgical intervention was more frequently performed in the brachial pseudoaneurysm group (22.2%) than in the femoral pseudoaneurysm group (0%) without reaching statistical significance (P = 0.07). Moreover, neurological disorders were observed only in the brachial pseudoaneurysm group (22.2%). In conclusion, the incidence of pseudoaneurysm was significantly higher in brachial access than in femoral access, indicating the potential risk of brachial access. Successful manual compression was frequently achieved in both groups, but neurological disorders were observed only in brachial access, suggesting the greater risk of brachial pseudoaneurysms.
