Abstract

PURPOSE:

To evaluate preliminary results with endovascular treatment (EVT) of intracranial aneurysms with mechanical detachable spirals.

MATERIALS AND METHODS:

EVT with spirals was attempted in 57 patients with 60 aneurysms (47 berry, nine large, and four giant aneurysms). Thirty-seven patients had subarachnoid hemorrhage (three of whom were also treated for associated aneurysm), nine were asymptomatic, six had headache, three had mass effect, and two had neurologic deficits.

RESULTS:

EVT with the spirals was achieved in 55 (92%) of the 60 aneurysms. Of 42 treated berry aneurysms and 13 treated large and giant aneurysms, 33 berry and nine large and giant aneurysms underwent 3-month angiographic follow-up. Complete occlusion was attained in 23 berry and four large and giant aneurysms, subtotal occlusion (doubtful or obvious small neck remnant) was obtained in eight berry and four large and giant aneurysms, and incomplete occlusion was obtained in two berry aneurysms and one giant aneurysm. These results were obtained after one procedure in 21 patients, after two procedures in 19 patients, and after three procedures in two patients. Seven patients had complications that necessitated infusion of urokinase. Permanent neurologic deficits were found in three. There were no deaths.

CONCLUSION:

Good results were obtained with EVT of intracranial aneurysms with mechanical detachable spirals. These spirals are characterized by rapid detachment and low cost.
