Figure 2. Computed tomography angiography image of the maxillary artery and its branches and angiographic images. (A) Computed tomography angiography (CTA) showing a branch of the maxillary artery (ie, the posterior superior alveolar artery; arrowhead) located peripherally from the middle meningeal artery. (B) Preembolization angiography showing blood flow in the maxillary artery branches. (C) Post-embolization angiography showing that coil implantation (arrow) had cut off the arterial blood supply around the pterygoid plate.
