Objective

The aim of his study was to evaluate the risks of endovascular therapy, aneurysm regrowth, recanalization and the need for reembolization.

Methods

A prospective analysis was performed on 211 endovascularly treated aneurysms from 2/2000 to 12/2003. 81 asymptomatic and 130 ruptured aneurysms were treated. The risk of endovascular therapy, aneurysm regrowth, recanalization and the need for reembolization was evaluated.

Results

Mean observation time was 10 months. Complete occlusion (100%) in the initial intervention was achieved in 171 patients (81.04%) an 80-95% occlusion rate in 21 aneurysms (9.9%). In 6 cases the occlusion rate was <80% (2.8 %). Recanalization rate of all aneurysms in the first follow-up was 27/118 (22.8%). 83/ 103 aneurysms (80.6%) with initial 100% occlusion rate remained completely occluded. 13/103 (12.6%) showed recanalization and 7/103 (6.8%) a neck regrowth (Table 2). In the group with 80-95% occlusion 14 patients were reassessed: 1 showed spontaneous occlusion, in 7 cases (50%) the initial neck remained, in 6 cases (42.8%) recanalization increased. In one case the initial <80% occlusion remained unchanged, in one case it increased. 10/118 (8.4%) aneurysms were recoiled. From these one was the <80% occluded aneurysm, 6 were from the 80-95% group and the other 3 from the initially totally occluded group.

Conclusions

In spite of low morbidity and mortality one in four aneurysms will show a recurrence. Initial occlusion rate seems to have an influence on the recanalization rate.
