While the number of physicians performing CAS continues to increase, MAE rates seen in this registry (4.4%) are well within an acceptable range, as was first seen in the SAPPHIRE randomized trial (4.8%). A significant decrease in MAE was seen in patients with anatomic risk compared with physiologic risk factors. The SAPPHIRE Worldwide Registry supports the use of CAS as an alternative to CEA in patients who are at high-risk for surgery due to anatomic risk factors.

In patients undergoing revascularization for lower extremity atherosclerotic disease, catheter-based PE achieves favorable procedural success and avoids the need for repeat revascularization at midterm follow-up. These findings support PE as a primary endovascular therapy for patients undergoing lower extremity arterial revascularization.

Stent-graft repair of traumatic thoracic aortic disruptions is technically feasible. Placement of a stiff wire in the right axillary artery and percutaneous left brachial artery access for arteriography are useful adjuncts during endograft deployment. Endovascular stent grafts may enable definitive repair or serve as a bridge until the patient is stable enough to undergo an operation, if necessary. This technique warrants further investigation.
