Transbrachial Mechanical Thrombectomy for Acute Ischemic Stroke in Marfan's Syndrome: A Case Report.

Objective: Marfan's syndrome (MFS) is a systemic connective tissue disorder with autosomal dominant inheritance. Cardiovascular complications of MFS such as aortic root or valve disease and aortic aneurysm or dissection are potential cause of access route problems of mechanical thrombectomy (MT) for acute ischemic stroke (AIS). Here, we report a case of a patient with MFS who underwent MT for AIS.

Case Presentation: A 58-year-old woman with MFS presented with a sudden onset of consciousness disturbance and right hemiparesis, and was referred to our hospital. After the infusion of tissue plasminogen activator, CTA showed a type III arch in the aortic arch and severe tortuosity of the thoracoabdominal aorta; thus, angiography was performed using the transbrachial approach. Left common carotid angiogram showed complete recanalization of the left middle cerebral artery. On the sixth day, the patient presented a sudden consciousness disturbance and left hemiparesis. MRA showed right internal carotid artery occlusion. MT was performed by the transbrachial approach, and complete recanalization was achieved on the first pass.

Conclusion: MT via the transbrachial approach is a treatment option that should be considered, especially in MFS, where the transfemoral approach is difficult due to anatomical problems.
