[Postoperative Chylothorax Likely to be Successfully Treated by Lymphangiography;Report of a Case].

A 74-year-old man underwent right upper lobectomy and systemic lymph node dissection with video-assisted thoracoscopic surgery. Chylothorax occurred on postoperative day (POD) 1st. Under fasting management, the patient underwent pleurodesis on POD 5th and 7th, subcutaneous octreotide acetate injection on POD 6th, and lymphangiography on POD 9th. The amount of drainage decreased on POD 10th, and the drainage tube was removed on POD 12nd. Lymphangiography has been reported as one of effective procedures to treat postoperative chylothorax. The present case is also considered to be successfully treated by lymphangiography.
