[申覆] 医学三　44 答案: C.外伤是引起chylothorax最常见的原因 我印象中是"医源性"的比较多 这里的"外伤"会让我觉得是车祸等造成的...... 如果答案写的是iatrogenic cause还差不多 Traumatic causes — Disruption of the thoracic duct anywhere along its course can cause a chylothorax. Surgical procedures distant from the thoracic duct can result in large chylothoraces if lymphatic tributaries to the thoracic duct are disrupted. In addition, injury to the intraabdominal portion of the duct causes chylous ascites that can pass through the diaphragm, resulting in a pleural effusion. =====重点来了===== [[["Surgical procedures account for most traumatic cases of chylothorax". ]]] Esophagectomy and surgery for congenital heart disease (including heart-lung transplantation appear to carry the greatest risk, but this complication has been reported in association with almost every thoracic surgical procedure, and may also complicate surgery of the neck or abdomen [5].
