Methods: All Marfan syndrome patients undergoing FS procedure from May 2002 to December 2014 were included.

Outcomes of Antegrade Stent Graft Deployment During Hybrid Aortic Arch Repair.

Background: Complex aortic arch disease can be a formidable challenge and is often treated with a two-stage elephant trunk technique. We examined our experience with hybrid arch repair with combined zone 0 stent graft deployment.

Methods: A retrospective review was conducted of all patients who underwent type 2 hybrid arch replacement and zone 0 antegrade endovascular stent graft deployments at a single university center from June 2010 to August 2015.

Femorofemoral Shunt During Surgery for Acute DeBakey Type 1 Dissection to Treat Peripheral Extremity Malperfusion.

Peripheral extremity ischemia in patients presenting with a DeBakey type 1 aortic dissection is an independent predictor for mortality. We present a patient with a DeBakey type 1 aortic dissection and peripheral extremity malperfusion that underwent simultaneous aortic repair and percutaneous femorofemoral shunt with arterial sidearm. Our approach allows for immediate peripheral extremity reperfusion and subsequent objective determination of the necessity of femorofemoral bypass via perfusion pressures.

Position Dependent Carotid Impingement Causing Recurrent Strokes.

We report the case of a young man with recurrent strokes over a four year period, all occurring after leaning forward. He had suffered damage to the right subclavian and right carotid arteries in a car accident 20 years prior. Review of history and imaging concluded that all of his infarcts had been in the distribution of the right carotid artery.

Results with a selective revascularization strategy for left subclavian artery coverage during thoracic endovascular aortic repair.
