Abstract

Chylothorax is defined as the accumulation of chyle in the pleural space, mainly by damaging to the thoracic duct. Tc-Dextran is a relatively new tracer for lymphoscintigraphy. A 40-year-old woman had recurrent chylothoraxes after thymoma resection and ligation of the thoracic duct owing to intraoperative suspected thoracic duct injury. She underwent lymphoscintigraphies using Tc-sulfur colloid and Tc-dextran, respectively, to identify the possible leakage site of the thoracic duct. The images showed increased Tc-dextran but unimpressive Tc-sulfur colloid activity at the leakage site. Based on the results, this patient received surgery anastomosing the thoracic duct and the azygos vein.

摘要

乳糜胸是指乳糜液在胸膜腔内积聚，主要是由于胸导管受损。Tc-右旋糖酐是一种用于淋巴闪烁显像的相对较新的示踪剂。一位 40 岁的女性因术中疑似胸导管损伤而行胸腺瘤切除术和胸导管结扎术，术后反复发生乳糜胸。她分别进行了 Tc-硫胶体和 Tc-右旋糖酐淋巴闪烁显像，以确定胸导管可能的漏液部位。图像显示漏液部位 Tc-右旋糖酐摄取增加，但 Tc-硫胶体活性不明显。基于这些结果，该患者接受了手术吻合胸导管和奇静脉。
