A Rare Case of Ligation of Thoracic Duct for Lt. Cervical Chyle Leakage Diagnosed as Lt. Cervical Tumor after Total Arch Replacement and Aortic Valve Replacement

Abstract

The patient was a 66-year-old man. He was following up after conservative treatment for type B acute aortic dissection. Computed tomography (CT) examination three months after the onset showed enlargement of the distal aortic arch and a new ulcer-like projection in the descending aorta. We judged them as indications for surgery. We were going to perform total arch replacement (TAR) and frozen elephant trunk (FET) for the distal arch aortic aneurysm, and thoracic endovascular aortic repair (TEVAR) for the processed aortic aneurysm in two stages. A CT scan 12 days after the TAR+ FET+AVR (aortic valve replacement) revealed a left cervical mass, and further examination revealed a left cervical lymphatic cyst. Conservative therapy involving drainage and a fat-restricted diet was initiated, but the drainage volume did not decrease. Therefore, we performed surgical thoracic duct ligation. We performed surgical thoracic duct ligation. We experienced a very rare case and report it here.
