Abstract

Patients and Methods: From January 2010 to December 2012, a series of 90 nonrandomized consecutive patients (mean age: 44.6 + 14.9 years) with intracranial aneurysms underwent endovascular coil embolization at our center. We excluded patients with dissecting, blood blister-like, or false aneurysms. All patients were evaluated by four-vessel angiography to determine the shape, size, number and location of the aneurysms. We recommended six month follow up control angiography to all patients, to which only 38 patients agreed. The data were analyzed by chi-square, Fisher exact and t-tests and alpha was set at lower than 5%.

Results: Total occlusion was seen in 76 patients (86.4%), subtotal occlusion in 6 subjects (6.8%), and partial occlusion in 6 patients (6.8%) after the procedure. There was no significant correlation between the aneurysm size, aneurysm neck size, location of the aneurysm; with total or subtotal occlusions. Eleven patients (12.5%) experienced some complication during the procedure including 2 tearing, 3 focal neurological signs, 3 vision disturbances, and 3 bleeding in aneurysm location. Major complications were significantly higher in posterior aneurysms in comparison with anterior ones. (55.6% versus 44.4% of the major complications; P = 0.015). Among patients who underwent control angiography, 34 patients (89.4%) had no change, two patients (5.3%) had new growth and two subjects (5.3%) had widening of the neck after 6 months of follow up. Furthermore, 50% of those aneurysms which had any changes in the 6 months follow up angiography were totally occluded. (P = 0.01).
