Minimally Invasive Approach to Management of an Isolated Pulmonary Artery Aneurysm: A Case Report

Lankenau Medical Center, Philadelphia, PA, USA.

OBJECTIVE: Review a unique presentation of pulmonary artery aneurysm and a minimally invasive approach to management.
METHODS: We present a case of an 85-year-old female with an enlarging right pulmonary artery aneurysm, which was effectively managed with endovascular stenting of the aneurysm.
RESULTS: An 85-year-old female with past medical history of hypertension and hyperlipidemia was found to be anemic and was diagnosed with a gastrointestinal bleed. During her initial work-up, she was incidentally found to have a fusiform aneurysm of the right middle lobe segmental pulmonary artery (Figure 1A). Her medical history was negative for pulmonary hypertension, congenital arteriovenous malformations, or vasculitis. An echocardiogram revealed normal pulmonary artery pressures. She was surveilled by thoracic surgery with serial imaging until the aneurysm was noted to have a significant interval increase in size. Prophylactic intervention was deemed necessary to curtail the risk of future fatal spontaneous rupture. The patient was presented with surgical and endovascular options and ultimately chose the latter. She underwent balloon-expandable covered stent placement within the aneurysm (Figure 1B). Serial imaging continues to demonstrate patency of the stent with thrombosis of the excluded aneurysm.
CONCLUSIONS: Pulmonary artery aneurysms are a rare occurrence and aneurysms of their branches occur even less frequently. The optimal management remains a clinical conundrum; with treatment options ranging from watchful waiting to surgical resection. We present a unique and successful approach of a patient who underwent endovascular stenting of a right middle lobe segmental pulmonary artery aneurysm, with collaboration of thoracic surgery and interventional radiology teams.
