Patients with aortic dissection were studied to define (1) anatomic and physiologic derangements in renal artery blood flow, (2) differences in clinically suspected renal malperfusion and true functional malperfusion, and (3) variations in endovascular interventions for the treatment of renal malperfusion. ⋯ Percutaneous aortic fenestration and renal artery stenting are both technically feasible and associated with an acceptable complication rate. Most patients respond well symptomatically, obviating the need for immediate surgical relief of renal artery obstruction and allowing for renal malperfusion recovery.

Thrombosis in unusual locations in the lower extremity veins has not been assessed. These veins are not imaged routinely and therefore information about them is lacking. ⋯ The involvement of the studied veins in DVT is extremely rare. Thrombosis in these veins can follow the natural course of thrombosis in the more usual locations and is associated with lethal incidences of PE. Therefore, the association of these veins with all the grave sequelae of thromboembolic disease suggests that inclusion of these veins in routine lower extremity duplex scans would be beneficial.

Carotid angioplasty and stenting (CAS) is a percutaneous alternative to carotid endarterectomy (CEA) for treating patients with carotid artery stenosis. This study sought to evaluate whether patients at increased perioperative risk for CEA may be treated with CAS while maintaining equivalent outcomes. ⋯ The data in this study demonstrate that high-risk patients undergoing CAS had comparable outcomes to low-risk patients undergoing CEA. This study supports the use of CAS as a reasonable alternative for patients at increased perioperative risk for CEA.
