Rescue snaring of Woven EndoBridge (WEB) with direct retrieval from aneurysm sac.

The Woven EndoBridge (WEB) device is an intrasaccular flow disruption device designed for the treatment of wide-necked aneurysms.1, 2 Once deployed into the aneurysm it initiates intra-aneurysmal stasis, thrombosis and occlusion, and flow diversion at the interface of the neck of the aneurysm with the parent vessel.3 The device offers the advantage of reduced operating time and reduced radiation exposure to the patient and the operator. We present a case of a patient in their 70s with a subarachnoid haemorrhage secondary to a ruptured aneurysm at the bifurcation of the right middle cerebral artery. Endovascular treatment was initially attempted with a 7 × 2 mm WEB single layer. Its inadvertent displacement following deployment occluded the superior M2 branch. A snare device was used to capture the proximal marker of the WEB and retrieve the device (Video 1).4- 5 The aneurysm was subsequently treated during the same session with a balloon and Comaneci-assisted coiling.
