Extra-Thoracic Aneurysms in Marfan Syndrome: A Systematic Review of the Literature

INTRODUCTION

Marfan syndrome (MS) most often shows as thoracic aortic aneurysm (TAA) or aortic dissection, but it may also involve other vascular territories.

OBJECTIVE

To identify those extra-thoracic vascular manifestations most frequently associated with MS.

METHODOLOGY

Systematic review of the literature with PRISMA criteria. The following databases were included: Medline, Embase, Web of Science (WOS), Cumulative Index of Nursing and Health Sciences Literature (CINHAL); Spanish database MEDESY Cochrane Central Register of Controlled Trials (CENTRAL).

RESULTS

10,008 articles were identified, leaving 155 for the first stage of data analysis (total incidence of aneurysms) and 83 for the second (descriptive data analysis). Overall, 518 aneurysms were identified: 149 in the head and neck, 94 in the extremities 275 in the aortic, iliac and visceral sectors. Mostly, they were simultaneously discovered during studies of the AAT. In the abdominal aorta, the presentation with rupture in 11 of 32 patients stands out. Resection and bypass was the most frequently used method for repair in the treated cases.

CONCLUSIONS

Although its frequency in the general population is unknown, this systematic review suggests that extra-thoracic aneurysmal arterial involvement in the MS may be more frequent than expected. We believe screening for aneurysms in other vascular sectors may be advisable, especially in patients with MS and AAT.
