AIM: To report angiographic and clinical results obtained in patients with supraclinoid segment blood blister-like aneurysms (BBLAs) of the internal carotid artery treated with stent-assisted coil embolization. MATERIAL AND METHODS: A retrospective review of patients, who were treated for a ruptured supraclinoid BBLAs of the internal carotid artery (ICA) from 2004 to 2010, was performed. Clinical data, including hospital records, operative reports, and angiograms, were analyzed. Outcome was assessed using the modified Rankin scale (mRS). RESULTS: Thirteen ruptured supraclinoid BBLAs in 13 patients were treated with stent-assisted coil embolization without any complication. Six patients recovered without any neurological deficits and three patients had mild neurological deficits (mRS 1 in one and 2 in two patients) due to late ischemic deficit. Three patients died of rebleeding and one died of intracranial infection after ventricular puncture for hydrocephalus. CONCLUSION: In our experience, the natural history of supraclinoid BBLAs is dismal. Some of the lesions rebled after stent-assisted coil embolization.
