Methods : Since October 1997 to July 2005, Twenty-four cases of paraclinoid ICA aneurysms were treated by endosaccular GDC embolization. The age ranged from 26 to 70 years, with a mean of 51 years, which consisted of 22 women and 2 men. The aneurysm size ranged from 2.5 to 16 mm, with an average of 6.3 mm. Results : Angiographic results immediately after the treatment were complete occlusion (CO) in 6 patients, neck remnant (NR) in 3 patients, and partial occlusion (PO) in 15 patients. Fifteen PO cases improved to CO in 10 cases and NR in 1 case at the 6 months follow-up angiography. Two large aneurysms had resulted in recurrence at the follow-up and 1 patient needed additional coil embolization. Coil migration to parent artery and TIA occurred in one patient as a complication. Conclusions : We can treat all 24 cases by endovascular treatment and it is thought to be a less invasive and efficient treatment for this location. The neck of paraclinoid ICA aneurysm is frequently and relatively wide, and balloon assisted technique is frequently necessary for the successful treatment. Silent thrombo-embolic events related to the endovascular procedure were evaluated by high signal intensity (HSI) on Diffusion weighted image (DWI-MRI), 48 hours after the procedure. Despite the administration of preoperative antiplatelet agents, high percentage of the HSI were detected on DWI-MRI after the procedure.}, pages = {45--52}, title = {Paraclinoid ICA ANに対する血管内治療}, volume = {16}, year = {2006} }
