AIM: Evaluate efficacy and safety of diagnostic and therapeutic endovascular interventions performed through transbrachial approach. Transbrachial artery catheterization has long been considered a secondary access site due to its related complication rate (7-11%). Low-profile and long-delivery endovascular systems, however, are reviving the interest in this approach.
METHODS: We retrospectively analysed all endovascular interventions attempted through a brachial artery access from 2003 to 2010. Two hundredth thirty seven consecutive patients (mean age 68.5 years, 89.5% male) underwent 168 transbrachial diagnostic (70.9%) and 69 therapeutic procedures (29.1%), characterised by micropuncture access (100%), 4-to-7 Fr sheath delivery systems and final digital compression (100%). CUSUM curves were created to evaluate learning effects and quality of care.
RESULTS: All but one procedure were completed according to their scheduled intention. The overall complication rate was 5.5% (5 pseudoaneurysms (2.1%), 4 transient ischemic attack (1.7%), 3 brachial artery thromboses (1.3%) and 1 cardiac tamponade (0.4%). Surgical intervention was required in four of these patients (30.8%). No significant differences were observed according to age or sex. CUSUM curves created at a 2% theoretical risk showed two statistically significant upward inflections: one early in the series associated with diagnostic procedures (P=0.043) and another at the end of the study related to therapeutic interventions (P=0.018).
CONCLUSION: Transbrachial catheterization is an effective and relatively safe access site for endovascular procedures. Its complication rate, although lower than before, still deserve it as a secondary access site. CUSUM curves let identify learning effects in diagnostic and interventional procedures.
