This small, incidental aneurysm of the anterior communicating artery (a and b) was discovered in the work-up of vertigo. Due to the aplasia of the right A1 segment and closer contact of the aneurysm to the right A2 segment, the p48 MW device was deployed from the right A2 into the left A1 segments (c) thereby covering the left A2 segment with subsequent sluggish flow and delayed filling of the left A2 territory (e). The patient remained, however, asymptomatic and the aneurysm was completely occluded on follow-up (d) with preserved filling of the left A2 segment (f). a time of flight MR-angiography; b working projection; c p48 MW device in situ with marked stagnation in the aneurysm; d first angiographic follow-up with complete occlusion of the aneurysm; e final run in AP projection after deployment of the p48 MW demonstrating the slow filling of the left A2 territory; f the angiographic follow-up in AP projection demonstrating the preserved flow in the left A2 despite the initial delayed filling
