Abstract

The Woven EndoBridge (WEB) device has emerged as a promising alternative to endovascular coiling. This case report demonstrates the use of stent-assisted WEB deployment for the embolization of multiple wide-neck posterior cerebral artery (PCA) aneurysms. A middle-aged patient was diagnosed with 3 unruptured aneurysms in the P3 and P4 segments of the right PCA, with sizes ranging from 2.5 mm to 6.6 mm. Given the small vessel diameter and distal location of the aneurysms, a combined approach was adopted. Coil embolization was performed for the most distal aneurysm, while stent-assisted WEB deployment was used for the proximal and middle aneurysms. The “flower bud” technique facilitated the safe positioning of the WEB device in challenging anatomical conditions. The procedure was successfully completed without complications, and the patient was discharged on postoperative day 7 with no neurological deficits. Follow-up at 3 months confirmed adequate embolization of all aneurysms, with in-stent stenosis managed conservatively.
