Core Tip

Core Tip: This study investigated the incidence and determinants of pseudoaneurysm formation following transarterial detachable balloon embolization in treating traumatic carotid-cavernous fistula over a decade. It highlighted balloon size as a significant risk factor, with larger balloons notably increasing pseudoaneurysm occurrence. Despite the high incidence of pseudoaneurysms, all affected patients remained asymptomatic through long-term follow-up, underscoring the procedure’s overall safety. These findings emphasize the critical role of selecting appropriate balloon sizes to mitigate risk and optimize outcomes, offering valuable insights for clinicians in managing this complex condition effectively.
