Role of C-Arm VasoCT in the Use of Endovascular WEB Flow Disruption in Intracranial Aneurysm Treatment

Abstract

BACKGROUND AND PURPOSE:The WEB aneurysm embolization system is still under evaluation but seems to be a promising technique to treat wide-neck bifurcation aneurysms. However, this device is barely visible using conventional DSA; thus, high-resolution contrastenhanced flat panel detector CT (VasoCT) may be useful before detachment to assess the sizing and positioning of the WEB. The purpose of this study was to evaluate the interest of VasoCT during WEB procedures.

Intrasaccular Flow Disruption in Acutely Ruptured Aneurysms: A Multicenter Retrospective Review of the Use of the WEB

“…Recent developments of the WEB with enhanced visibility and new angiographic visualization techniques seem to enable us to reliably detect and avoid protrusion as a potential source of adverse events in the future. 23 There was 1 aneurysm with partial thrombosis of the sac that had recurred at 3 months. Hope that the greater and more even surface of the WEB may sufficiently prevent migration into the clot, regularly seen with bare coils, is not warranted at the moment.…”

Flow-Diverter Stents for the Treatment of Saccular Middle Cerebral Artery Bifurcation Aneurysms

“…From our prospectively maintained data base, we extracted all MCA bifurcation saccular aneurysms treated with an FDS and collected the following data for each patient: age, sex, aneurysm location and biometry (max-imum diameter, neck size, aspect ratio), rupture status, previous treatment, the modified Rankin Scale scores at the time of admission and discharge, modalities of treatment, intraoperative complications (aneurysm rupture, thromboembolic events, deployment failure), and postoperative complications (delayed bleeding, thromboembolic events). Immediate postoperative DSA, 3D rotational angiography, and VasoCT images (Philips Healthcare, Best, the Netherlands) 21,22 were collected along with any available follow-up imaging data. The last mRS evaluation during follow-up was also recorded.…”
