Endovascular Treatment using a Covered Stent for Life-threatening Hemorrhage of Cerrical Artery in Two Patients with Advanced Esophageal Cancer after Chemoradiotherapy

Abstract

Two cases of thoracic artery extravasation were treated with covered stents. Both cases who had advanced esophageal cancer after irradiation were in hemorrhagic shock condition, because of life-threatening hemorrhage. Enhanced CT revealed extravasation of the left common carotid artery, accompanied by right aberrant subclavian artery in one case. Endovascular repair using covered stents resulted in complete exclusion of the pseudoaneurysm and control of the bleeding. Endovascular treatment with covered stents for hemorrhage of common carotid and subclavian arteries can be a safe and helpful treatment.
