Rare locations of peripheral aneurysms in Marfan syndrome treated surgically: a case report

Abstract

Marfan syndrome (MFS) is a connective tissue disorder that can lead to cardiovascular and musculoskeletal abnormalities. Aortic aneurysms and dissections are frequently seen in patients with MFS whereas peripheral vascular aneurysms in subclavian and axillary arteries territory considered very unusual. We reported a case of 54-year-old female with known history of MFS who had undergone a mechanical valve Bentall procedure due to severe aortic regurgitation and ascending aorta aneurysm in addition to thoracoabdominal aortic repair and who presented with a pulsatile painful mass in her right axillary region that turn to be significant true aneurysms of right subclavian and axillary arteries. To relive symptoms and to avoid further complications patient underwent successful surgical repair. Our case demonstrated rare locations of true peripheral aneurysms as a possible manifestation of MFS appeared several years post Bentall procedure and thoracoabdominal aortic repair and highlights also the importance of long-term monitoring to detect earlier such manifestation and avoid complications by surgical repair.
