Comparative Study
Is carotid angioplasty and stenting more cost effective than carotid endarterectomy?
Carotid angioplasty and stenting (CAS) has been advocated as a minimally invasive and inexpensive alternative to carotid endarterectomy (CEA). However, a precise comparative analysis of the immediate and long-term costs associated with these two procedures has not been performed. To accomplish this, a Markov decision analysis model was created to evaluate the relative cost effectiveness of these two interventions. ⋯ CEA is cost saving compared with CAS. This is related to the higher rate of stroke with CAS and the high cost of stents and protection devices. To be economically competitive, the mortality and major stroke rates of CAS must be at least equivalent if not less than those of CEA.

Case Reports
Aortoduodenal fistula and associated rupture of abdominal aortic aneurysm after endoluminal stent graft repair.
The main complications of endovascular repair of abdominal aortic aneurysms are vascular leaks and rupture, although infection and aortoduodenal fistulas have also been reported rarely. We report a case of aortoduodenal fistula with separate retroperitoneal rupture of an abdominal aortic aneurysm after endovascular stent graft repair. ⋯ The patient underwent open repair and did well. To our knowledge, this is the first case report of aortoduodenal fistula and associated retroperitoneal rupture of the aneurysm after endovascular stent graft repair of an abdominal aortic aneurysm.
