成人心脏外科术后乳糜胸的研究进展

Chylothorax Complicating Adult Cardiac Surgery Procedures

乳糜胸是成人心脏手术后少见的并发症,多由于胸导管或其分支受到阻塞、损伤,乳糜溢出至胸膜腔所形成,可使患者出现蛋白质、能量缺乏,电解质紊乱,增加凝血障碍或感染的风险。如果不及时进行治疗,死亡率较高,保守治疗是成人心脏术后乳糜胸的首选治疗方法。现通过汇总分析近十年成人心脏术后发生乳糜胸的病例报道,对其发病机制和治疗策略进行综述。

Chylothorax is a rare complication after cardiac surgery in adults.It is caused by the extravasation of chyle into the pleural space,due to obstruction or injury to the thoracic duct or its branches.Chylothorax increases the mortality rate and may cause nutritional deficiencies,protein deficiency and electrolyte disorders,so as to increasing the vulnerability to infections and coagulation disorder.Conservative management is appropriate as initial treatment for cardiac postsurgical chylothorax.In this article,we reviewed pathogenesis and treatment strategies of chylothorax,through a summary analysis of chylothorax cases in the past ten years.
