Tumor embolism after pneumonectomy for primary pulmonary neoplasia.

We report a case of tumor embolism of the lower right extremity after right pneumonectomy. This is an infrequent complication and in most cases occurs during the intraoperative or immediate postoperative period. Our patient underwent surgery for primary pulmonary neoplasia (squamous cell carcinoma) and 4 hours later showed clinical signs of acute arterial occlusion in the lower right extremity. An emergency embolectomy was performed and a thrombus with tumor characteristics was extracted from the right common femoral artery. The pathologic features of this thrombus were identical to those of the pulmonary tumor.
