Pulmonary Artery and Intercostal Artery Pseudoaneurysms After Penetrating Injury.

Traumatic pulmonary artery and intercostal artery pseudoaneurysms are rare pathologies that can occur after a penetrating injury. Most times, only 1 pseudoaneurysm needs to be addressed. Options for management include simple observation, endovascular intervention with coiling, embolization, and stenting, as well as surgical intervention ranging from ligation to pneumonectomy. We present the case of a 20-year-old man who developed multiple pulmonary artery pseudoaneurysms and an intercostal artery pseudoaneurysm after sustaining a single gunshot wound to the chest. After multiple episodes of bleeding from several pseudoaneurysms, the patient ultimately required a pneumonectomy.
