Lower extremity woven and nonwoven venous stent morphology and luminal changes.

Objective: Venous stents are a common treatment modality for obstructive venous disease. Venous stents differentiate themselves by either a woven or braided structure, open or closed cell arrangement or based on material composition (elgiloy vs nitinol). Changes in the morphology of venous stents over time may contribute to restenosis or thrombosis.

A hybrid approach to persistent sciatic artery fusiform aneurysm repair.

A persistent sciatic artery is a rare vascular anomaly that is prone to early atherosclerotic development and aneurysmal degeneration. Repair of the degenerative aneurysm is critical because it can lead to rupture, thrombosis, distal embolization, and sciatic nerve damage from compression. We report a case of a symptomatic unilateral persistent sciatic artery fusiform aneurysm that was treated using a simultaneous open surgical and endovascular approach.
