Tumor embolism to LAD during pneumonectomy. A case report.

Arterial embolization from bronchogenic carcinoma is a rare complication and more commonly occurs intraoperatively during pneumonectomy. We report an unusual case of intraoperative tumour embolism to LAD (left anterior descending artery) and aorta during left pneumonectomy due to tumour involvement of the inferior pulmonary vein. High risk cases should be evaluated by preoperative transesophageal echocardiography. If tumour involvement of the inferior pulmonary vein is demonstrated, a modification of the surgical technique or alternative modality of treatment should be used.
