An Unusual Case of Blunt Traumatic Pulmonary Artery Pseudoaneurysm Detected within a Day

Abstract

An unusual case of blunt traumatic pulmonary artery pseudoaneurysm detected within a day 在一天之內檢測到的一個罕見的鈍性外傷性肺動脈假性瘤 SR Yeom 廉釋蘭, MK Min 閔門基, SH Lee 李成和, SW Park 朴星昱 Chest trauma can injure intrathoracic vessels, usually affecting the aorta and arch branches; however, a traumatic pulmonary artery pseudoaneurysm (PAP) has been reported, albeit relatively rarely. Blunt chest trauma as an aetiology for a PAP is even more rare than penetrating chest trauma. There is usually a time delay from several days to several months between injury and detection of a PAP. Traditionally, operative management has been recommended because of the risk of PAP rupture. Here, we describe an unusual case of a PAP following blunt trauma that was detected early on computed tomography, 8 hours after injury, and the PAP resolved with conservative management.
