Postoperative chylothorax after pulmonary wedge resection in two patients who underwent radical neck dissection: A case report.

Postoperative chylothorax after wedge resection without mediastinal lymph node dissection is extremely rare. Herein, we report two cases: one case of postoperative chylothorax that developed after wedge resection and another of expanded collaterals detected during thoracoscopic surgery. We believe the cause of this complication to be the history of neck and pulmonary ligament dissections during pulmonary surgery.
