Summary

Introduction

Flow-diversion treatment of cerebral aneurysms with the Pipeline Embolization Device (Covidien, Irvine, California) has been around for nearly 13 years, yet we are still struggling with some fundamental issues, such as optimal device-size selection and optimal flow diversion (ie, which aneurysms need Ͼ1 device for a cure, and how we can identify those aneurysms). Some of us use as individualized an approach to each patient and aneurysm as possible and spend considerable time ruminating over minute differences in device length and diameter to be implanted, not to mention the guesswork that goes into predicting how much flow diversion is necessary or enough to ensure complete aneurysm occlusion after the first treatment (ie, do we use 1 or multiple devices?). The authors of the article embarked on an experiment to assess the potential use of a virtual-simulation software in planning Pipeline flow diversion in 74 aneurysms.
