Arterial embolization from bronchogenic carcinoma is a rare complicati
on 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 sh
ould be evaluated by preoperative transoesophageal echocardiography. I
f tumour involvement of the inferior pulmonary vein is demonstrated, a
modification of the surgical technique or alternative modality of tre
atment should be used.
