Abstract
Background
Rupture of internal carotid artery (ICA) pseudoaneurysm is a lethal complication in patients with nasopharyngeal carcinoma (NPC). Angiography is the best diagnostic and treatment method. The aim of embolization is to block the pseudoaneurysm; but sometimes, total occlusion of great vessels is ineludible. We describe a case of NPC post‐radiation therapy and with ruptured pseudoaneurysm treated by angio‐embolization.
Methods
The patient had received embolization with numerous tools such as stent grafts, balloons, and bare stents with or without filter protection.
Results
After failing to pass through the narrow lumen by embolizing tools, the right ICA finally occluded spontaneously by self‐thrombosis.
Conclusion
Although the angio‐embolization is a good method to resolve the problems of ruptured pseudoaneurysm, there is still high mortality and morbidity. Being aware of the clinical presentations and the changes of images may alert us to predict the happening earlier. © 2008 Wiley Periodicals, Inc. Head Neck, 2008
