Abstract
We report a patient with a pseudoaneurysm of a transverse facial artery that was treated by transarterial embolization. A 50-year-old female, following an alcohol induced fall, developed a massive hematoma in her right buccal area. The next day, she was admitted to our hospital. Computed tomography revealed a large subcutaneous hematoma in her right buccal area. Enhanced computed tomography also revealed extravasation of contrast medium from a peripheral branch of the right transverse facial artery. Transarterial embolization was performed. We introduced a 1.5Fr. Marathon microcatheter into the right transverse facial artery more distally. First, we occluded a tiny branch to the skin with an ED coil-10, and then occluded the pseudoaneurysm and proximal portion of the artery with N-butyl cyanoacrylate (NBCA). The final external carotid angiogram revealed no pseudoaneurysm. The 1.5Fr. Marathon microcatheter was very useful because the vessel had a small diameter, and deployment of an ED coil was necessary.
