Summary :
Objectives: Pseudoaneurysms of the carotid artery are a rare but serious cause of epistaxis. They can be rapidly life-threatening. Usually resulting of a surgery or a traumatism, pseudoaneurysms can express themselves by recurrent epistaxis. Management of these epistaxis is discussed. Methods: The authors present two cases and effect a review of the literature. Results: The first patient presented with a pseudoaneurysm few days after a transsphenoidal surgery. The second patient presented with a pseudoaneurysm fourteen years after a radio-surgical treatment of an ethmoidal and frontal epidermoid carcinoma. Diagnosis was suspected during nasal endoscopy and confirmed in both cases with angio-CT and arteriography. The first patient underwent a selective embolization. The second patient had to have a carotid occlusion due to a sudden severe haemorrhage, resulting from a pseudoaneurysm rupture following the embolization attempt. Conclusion: Review of the literature confirms the indication of endovascular intervention. The optimal management is carotid occlusion, provided the patient can tolerate carotid test occlusion and the circle of Willis is satisfactory. In some cases, a preservative treatment may be possible, which could be either pseudoaneurysm embolization or the placement of a covered stent.
