Pulmonary Arteriography for the Assessment of Technical Feasibility of Sleeve Resection in Lung Cancer

Abstract

Background. Pulmonary arteriography has been reported to be useful in the preoperative assessment of patients with lung cancer to determine the technical resectability and feasibility of pneumonectomy by imaging the main right and left pulmonary arteries. In this report, we describe the use of selective pulmonary arteriography in the assessment of lobar resectability. Methods. Selective pulmonary arteriography provides a detailed anatomic view of the lobar branches and has been used at our institution for the past 30 years to preoperatively investigate patients who are candidates for a sleeve lobectomy. Results. Three cases are described that demonstrate the usefulness of selective pulmonary arteriography in the assessment of the technical feasibility of sleeve resection in patients with lung cancer. Conclusions. Arteriographic findings may accurately show whether a sleeve lobectomy is technically possible, that only a pneumonectomy is possible, or that the only safe way to ensure clearance of the pulmonary artery is to perform arterioplasty. This information may obviate an unnecessary thoracotomy in patients who are judged on the basis of a physiologic assessment to be unable to tolerate a pneumonectomy.
