“…[16][17][18] Its etiology remains unknown. 19 Recently, segmental arterial mediolysis (SAM) has been recognized as a medial degenerative disease akin to CMN. Its characteristics are mediolysis, a tearing separation of the outer media from adventitia, an arterial gap, and a fl orid reparative response that replaces the zones of mediolysis and fi lls areas of medial adventitial separation.…”

Ruptured isolated external iliac artery true aneurysm associated with cystic medial necrosis: Report of a case

et al. 2009

View full text Add to dashboard Cite

We report a case of a ruptured isolated true external iliac artery aneurysm (EIAA). A 78-year-old woman was admitted to our institution in a shock state after the sudden onset of severe pain in the right hypogastric region. A pulsating mass was found in her right lower abdomen. Computed tomography (CT) with contrast medium showed an isolated EIAA, 40 mm in diameter, with a massive retroperitoneal hematoma. She underwent emergency resection of the aneurysm and reconstruction of the affected artery, without any complications. Histological examination confirmed a true aneurysm caused by cystic medial necrosis (CMN). She had no ocular, cardiac, or orthopedic abnormalities. We review the literature on isolated true aneurysms of the external iliac artery, which are extremely rare, and discuss their clinical manifestations.

“…Documentation of intracranial circulation, with attention to the vertebrobasilar system, is crucial in procedures that involve the possibility of right or left vertebral artery ligation. 22,23 Color-flow Doppler ultrasound confirmed flow and non-variation of its direction. Digital angiography identified flow in both vertebral arteries and, according to color-flow Doppler ultrasound, there was no change in flow direction or in systolic and diastolic velocity peaks.…”

We report on a 46-year-old female patient with Marfan's syndrome and a right subclavian artery aneurysm following open repair of type A aortic dissection. The patient was treated with a hybrid approach, combining innominate to right common carotid stent grafting and carotid to right axillary artery bypass. The postoperative course was uneventful and a duplex ultrasound confirmed successful aneurysm exclusion.Keywords: Subclavian artery, Marfan's syndrome, endovascular procedures, stent graft.

“…Our patient did not have a family history or the specific skeletal abnormalities associated with Marfan syndrome. The numbers of reports of vascular lesions associated with cystic media degeneration in non-Marfan patients have recently increased and include aortic, carotid, and other visceral artery lesions [3][4][5]. Cystic media degeneration weakens the aortic media, which results in aneurysmal dilation.…”

A 62-year-old woman with a history of dyslipidemia and hypothyroidism was referred to our institution with syncope. Cardiac tamponade due to spontaneous rupture of a 50-mm aneurysm of the coronary artery was diagnosed by transthoracic echocardiography, enhanced computed tomography, and coronary angiography. Emergency surgery was performed, and despite developing postoperative complications such as acute renal insufficiency, the patient was discharged from hospital without sequelae 89 days later. Histological findings revealed cystic media degeneration, but neither significant atherosclerotic changes nor inflammatory cell infiltration. Although coronary artery aneurysms are comparatively rare and generally asymptomatic, those over 30 mm in diameter are considered to be at increased risk of rupture. A coronary artery aneurysm of about 50 mm ruptured in our patient, supporting this view.
