Different Embolization Approaches for the Treatment of Posttraumatic Pseudoaneurysm of the Internal Maxillary Artery

Abstract

Pseudoaneurysm is an abnormal dilation of an artery that could be caused either by iatrogenic or traumatic events and it is associated with high rupture risk. Pseudoaneurysm rarely involves internal maxillary artery. Computed tomography angiography and digital subtraction angiography are essential tools to perform a proper diagnosis and treatment of pseudoaneurysms. The authors described 2 different cases of internal maxillary artery pseudoaneurysm, treated by different embolization approaches. The first case was treated by a well-known arterial catheterism technique, whereas the second one was performed by an uncommon approach with a direct percutaneous puncture.

Aseptic necrosis of the maxilla on embolized patient: a challenger condition

“…The material used to embolization in the present case was microparticles, but there are other options as acrylic adhesive and gelling solutions. Therefore, the decision is according to the clinical application and the expected effect (5,6).…”
