Ischemic Stroke Secondary to a Stab Wound to the Neck in a Young Adult

Figure 2

Angiography of the head and neck vessels. A pseudoaneurysm of the left vertebral artery is observed at the level of C4 with an associated arteriovenous fistula and without signs of active bleeding. The pseudoaneurysm measures 8.5 mm anteroposterior diameter, 7.3 mm transverse diameter, and 8 mm craniocaudal diameter. Hyperdensity of adjacent venous structures is observed, and the venous phase is better visualized after configuring an arteriovenous fistula with a filiform filling of the distal vertebral artery.
