Purpose:
Evaluation of clinical and morphological results in 44 consecutive patients with 45 aneurysms of the posterior circulation.
Methods:
Retrospective analysis of patient charts and angiograms of all vertebrobasilar aneurysms diagnosed in our department between 10/95 and 08/99. All aneurysms were treated.
Results:
36/44 pts had a hemorrhage. Hunt/Hess (HH) gradings were as follows: HH1 in 10, HH2 in 6, HH3 in 9, HH4 in 10 cases, and HH5 in 1 case. 38 pts with 39 aneurysms were treated exclusively in the endovascular way, 3 pts with 3 aneurysms were operated on. 3 patients had to be operated upon following insufficient endovascular treatment. Endovascular treatment resulted in 63% total and 27% subtotal occlusions, results being stable in 85%. For our pts as a whole, the grading according to the Glasgow Outcome Scale (GOS) was GOS1 in 4, GOS3 in 8, GOS4 in 7, and GOS5 in 25 cases.
Conclusion:
Despite a less favourable clinical status of pts pre-treatment, the results of our interdisciplinary concept compare favourably with those of other surgical or interventional groups.
