A simple method for evaluating the quality of microvascular anastomoses performed in vitro.

Objective: The aim of this paper is to describe a simple and effective method for evaluating the quality of microvascular anastomoses performed in vitro.

Methods: After the microvascular anastomosis has been performed in vitro, the vessel is cannulated at a distance of several millimeters from the anastomosis site with a catheter that is connected to a syringe filled with commercially available silicone glue. The silicone glue is slowly injected into the artery until the whole specimen is filled.

Rapid ventricular pacing for flow arrest during cerebrovascular surgery: revival of an old concept.

Background: Intraoperative rupture of a cerebral aneurysm can be a devastating event that increases operative morbidity and mortality. Rapid ventricular pacing (RVP) is a technique used in interventional cardiology to obtain flow arrest for short periods of time.

Objective: To present our experience using RVP for flow arrest during cerebrovascular surgery.

Microsurgical removal of Onyx HD-500 from an aneurysm for relief of brainstem compression. Case report.

The authors report the successful removal of Onyx HD-500 from an aneurysm sac by means of ultrasonic aspiration. This 46-year-old woman presented with progressive spasms of her left arm and leg due to mass effect and compression on the right cerebral peduncle 5 years after endovascular treatment of an unruptured giant posterior communicating artery aneurysm with Onyx HD-500. No filling of the aneurysm was detected on angiography.
