RESUMEN
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.

OBJECTIVES: Short- and long-term evaluation of the efficacy and safety of radiofrequency velar coblation for simple snoring. MATERIAL AND METHODS: From February 2000 to May 2004, 175 patients underwent a single radiofrequency session for velar coblation. All patients suffered from snoring without sleep apnea. They presented modifications of the velo-pharyngeal region but did not have tonsillar or basilingual hypertrophy. Outcome was assessed in terms of pain, changes in snoring, secondary effects and complications at three months and one, two, and three years. Secondary uvulectomy was performed in 28 patients. RESULTS: At three months, snoring had decreased in 82% of patients with complete resolution in 12%. Outcome remained unchanged in 70% of patients at one, two, and three years. After uvulectomy, snoring declined in 96% of patients with complete resolution in 48%. Post-treatment pain lasted less than five days in 68% of patients. Mean duration was three days. Fifteen patients developed pharyngeal paresthesia which regressed at one year. Two patients had a nasal voice and three developed necrosis of the uvula. CONCLUSION: Velar coblation is a simple treatment for snoring which can be performed in a single session. The best results are achieved in patients whose body mass index is below 25 and after secondary uvulectomy.
