Traumatic Pseudoaneurysm of the Superficial Temporal Artery

      Traumatic pseudoaneurysm (PA) of the superficial temporal artery is a rare but potentially dangerous condition that can occur after blunt facial trauma. Although true aneurysms are characterized by dilation or bulging of all three intact layers of the vessel wall, PAs are a disruption of the vessel in which the blood is only bound either by the outermost tunica adventitia or by adjacent soft tissues. If the wall subsequently ruptures, patients are at risk of hemorrhaging. The superficial temporal artery is especially susceptible to PA formation among facial vasculature (
