Percutaneous radiologic gastrostomy: a 12-year series.

Background/aims: Interventional radiologists have played a main role in the technical evolution of gastrostomy, from the first surgical/endoscopical approaches to percutaneous interventional procedures. This study evaluated the results obtained in a 12-year series.

Methods: During the period December 1996 to December 2008, 254 new consecutive gastrostomies and 275 replacement procedures were performed in selected patients.

Safety of unprotected carotid artery stent placement in symptomatic and asymptomatic patients: a retrospective analysis of 30-day combined adverse outcomes.

Purpose: To retrospectively evaluate the outcome of carotid artery stent placement (CAS) without the use of embolic protection devices (EPDs) in a large cohort of patients.

Materials And Methods: Institutional review board approval and informed consent from all patients were obtained. Preprocedure color Doppler ultrasonography (US), magnetic resonance (MR) imaging, or computed tomography (CT) were used to evaluate stenosis severity (70% or greater).
