Successful facial artery pseudoaneurysm coiling and pedicle preservation following free tissue transfer

Abstract

Patients undergoing free tissue reconstruction are at risk for development of an anastomotic pseudoaneurysm, which may present as delayed neck hemorrhage or a pulsatile neck mass. Diagnosis may be achieved by noninvasive imaging, angiography, and exploration. Management strategies for head and neck pseudoaneurysms have included open vessel ligation, open direct vessel repair, endovascular parent vessel embolization, and, most recently, endovascular pseudoaneurysm embolization. In patients with anastomotic pseudoaneurysms where adequate flap inosculation is doubted, endovascular pseudoaneurysm embolization with pedicle preservation may be an appropriate primary treatment approach. We discuss the successful endovascular coiling of an external carotid artery branch anastomotic pseudoaneurysm in a patient one month after free tissue reconstruction of a total laryngopharyngectomy and partial glossectomy defect.
