Pseudoaneurysm of the internal carotid artery secondary to tonsillectomy.
A case of pseudoaneurysm of the cervical internal carotid artery secondary to tonsillectomy is presented and the pathogenesis of this vascular abnormality is discussed. Due to morphologic and inflammatory changes in the lateral pharyngeal wall, the entrapment aneurysm was maintained. The internal carotid artery was initially occluded above the carotid bifurcation. The transcatheter occlusion of the distal stump of this vessel, by steel coils, replaced a mutilating approach for exposure and ligation near the base of the skull.
