title: Percutaneous Embolization of Delayed External Carotid Artery Pseudoaneurysm Eight Years after Partial Parathyroidectomy.
abstract: External carotid artery pseudoaneurysm (ECAP) is very rare. The usual mechanism is trauma or iatrogenic. We report a case of a patient with an asymptomatic, chronic ECAP secondary to partial parathyroidectomy. Percutaneous injection of the 2-component Fibrin Sealant (Tisseel; Baxter int, Deerfield, IL) with the 2 active ingredients (Sealer Protein Solution and Thrombin Solution) was carried out with successful occlusion of the pseudoaneurysmal sac. The 6-month follow-up computed tomographic scan confirmed the ECAP thrombosis. The ECAP endovascular approach is less invasive and reduces the complications of the open surgical intervention, especially in high-risk patients or presenting with hostile neck.
