Proximal endovascular flow blockage for cerebral protection during carotid artery stenting: results from a prospective multicenter registry.

Purpose: To evaluate the feasibility of cerebral protection during carotid artery stenting (CAS) using the Mo.Ma device, which prevents cerebral embolization by proximal endovascular blockage of blood flow in the internal and external carotid arteries.

Methods: In 14 European centers, 157 patients (121 men; mean age 68.

Comparison of stenting with minimally invasive bypass surgery for stenosis of the left anterior descending coronary artery.

Background: Minimally invasive bypass surgery and coronary-artery stenting are both accepted treatments for isolated stenosis of the proximal left anterior descending coronary artery. We compared the clinical outcomes after these two procedures.

Methods: A total of 220 symptomatic patients with high-grade lesions in the proximal left anterior descending coronary artery were randomly assigned to treatment--110 to surgery and 110 to stenting.
