An Isolated Aneurysm of the Abdominal Aorta in a Patient with Marfan Syndrome-A Case Report

Marfan syndrome in a Ghanaian male: The diagnostic challenges

Marfan syndrome (MFS) is an autosomal dominantly inherited condition that has varying phenotypic expressions. This case report describes one such African patient, from Ghana, who had typical clinical and imaging traits of MFS but was first diagnosed incidentally at the age of 23 years. In this report, we explore the challenges of early diagnosis in this population.

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.

Complex and Successful Management of a Symptomatic Isolated Abdominal Aortic Aneurysm in a Pregnant Woman with Marfan Syndrome

Aortopathies associated to Marfan syndrome (MFS) are important causes of maternal death during pregnancy. We present a 27-year-old and 24-week pregnant MFS woman who arrived to the emergency department with increasing abdominal pain; an obstetric ultrasound showed an Abdominal Aortic Aneurysm (AAA), a multislice computed tomography angiography (CTA) confirmed and demonstrated a 7.3 centimeter (cm) infrarenal AAA without evidence of dissection. A multidisciplinary committee determined that an open repair would lead to a significantly high maternal-fetal morbidity and mortality. Although endovascular repair (EVAR) in MFS patients remains controversial, an urgent bridge therapy was considered to be the best option. She was transferred to the angiography suite for EVAR to prevent AAA rupture and ensure a satisfactory pregnancy. The patient and fetus presented no complications during the procedure and were discharged 3 days later. She continued her pregnancy without eventualities and an elective C-section was performed on week 36. A CTA imaging at 12 months revealed type 1A and 3 endoleaks, we decided to perform endograft explant and a definitive open repair, there were no complications during the procedure, the patient is currently asymptomatic. Our case illustrates a complex decision and management that successfully avoid morbidity and mortality of a MFS mother and her product; additionally, this experience reinforces the need for lifelong and close surveillance in these patients.
