A Surgical Case of Bronchial Artery Aneurysm Directory Connecting with Pulmonary Artery

Abstract

We present a surgical case of bronchial artery aneurysm (BAA) connecting pulmonary artery accompanied with racemose hemangioma. This is a third surgical case report of BAA directly connecting pulmonary artery in the English literature. A 63-year-old female was found a BAA, 2 cm in diameter, connecting right A4 pulmonary artery. The patient underwent two attempts for embolization. However, due to extensive collaterals, there was persistent flow in the aneurysm. Standard lateral thoracotomy was performed. A BAA was located between A4 and A5 PA. A small branch of A4 PA was separated, and the small vessel connecting to the BAA could be ligated. A5 PA was separated similarly, however BAA was ruptured not to identify the other small vessel connecting to the BAA. After a clamp of the BAA, middle lobe lobectomy was performed. We removed the aneurysm with dilated bronchial artery connecting to the aneurysm. The postoperative course was uneventful.
