Comparative Study
Primary carotid artery stenting versus carotid artery stenting for postcarotid endarterectomy stenosis.
Carotid artery stenting (CAS) has been advocated as an alternative to carotid endarterectomy (CEA) in high-risk surgical patients, including stenosis after CEA. This study compared early and midterm clinical outcomes for primary CAS vs CAS for post-CEA stenosis. ⋯ CAS for post-CEA stenosis carried a lower risk of early postprocedural neurologic events than primary CAS, with a trend toward a higher restenosis rate during follow-up.

Comparative Study
Laparoscopic-assisted treatment of abdominal aortic aneurysm requiring suprarenal cross-clamping.
Hand-assisted laparoscopic surgery (HALS) was previously employed to treat patients with infrarenal abdominal aortic aneurysm (IAAA). The use of HALS for juxtarenal abdominal aortic aneurysm (JAAA) has never been validated. In this study, we report our experience with this technique to demonstrate its feasibility and prove its safety in dealing with JAAA. ⋯ The HALS technique proved to be feasible and safe not only for patients with IAAA, but also for the management of patients with JAAA. No significant difference could be shown in the comparison between the two groups, apart from the expected higher rate of postoperative renal dysfunction after suprarenal clamping. In view of the demonstrated benefit of this minimally invasive approach, we believe that it should be included among the alternative options of treatment for these patients.

This study evaluated the feasibility and outcomes of percutaneous transhepatic balloon angioplasty (PTBA) of the hepatic vein in the management of Budd-Chiari syndrome (BCS) secondary to hepatic venous outflow obstruction. ⋯ PTBA of the hepatic vein is a safe and effective treatment of BCS. It is currently the most physiologic procedure, and the risk of postoperative encephalopathy is minimized because portal flow is not diverted. Midterm outcomes are satisfactory. Further investigation of the long-term outcomes is needed.
