Long-term outcome of infrapopliteal catheter-based intervention for critical limb ischemia.

Context: Percutaneous treatment of tibioperoneal occlusive disease is associated with decreased morbidity compared with bypass surgery. The long-term patency and limb salvage rates are not well documented.

Aims: To evaluate the long-term outcome of endoluminal interventions for tibioperoneal lesions.

Cerebral protection devices reduce periprocedural strokes during carotid angioplasty and stenting: a systematic review of the current literature.

Purpose: To compare through a systematic review of published literature the stroke outcomes in protected and unprotected carotid artery stenting (CAS).

Methods: PubMed and Cochrane electronic databases were queried to identify peer-reviewed publications from 1995 to 2007 meeting our pre-defined criteria for inclusion (English language, human only, at least 20 patients reported) and exclusion (procedures performed for the treatment of total occlusion, dissection, or aneurysmal disease; urgently performed procedures; use of covered stents; access other than transfemoral). Information was collected on a standardized data abstraction form for pooled analysis of total strokes within 30 days of procedure in all patients and in symptomatic and asymptomatic subgroups.
