Embolization of a pseudoaneurysm of the innominate artery with a Woven EndoBridge (WEB) device.

The Woven EndoBridge (WEB) is an intra-aneurysmal flow disruptor designed for the treatment of broad-based arterial aneurysms with a high safety and effectiveness profile.1, 2 It does not require concomitant antiplatelet therapy compared to other devices such as flow diverters or intracranial stents. Innominate artery pseudoaneurysms are a rare consequence of blunt traumatic injury, infection, or atherosclerotic disease.3, 4 We describe the case of an innominate artery pseudoaneurysm successfully treated with a WEB SL device instead of stenting, therefore alleviating the need for dual antiplatelet therapy. The treatment was successful and uneventful and postprocedural computed tomography angiography confirmed the complete occlusion of the pseudoaneurysm.
