摘要:
This paper analyzes the success of endovascular management of ruptured and un-ruptured vertebral artery aneurysms. Sixty-three patients with 65 vertebral (both acute dissection and chronic larger aneurysms are included) treated at our hospital form the basis of the analysis. Clinical outcome was evaluated using the modified Rankin Scale. Angiographic follow-up data was obtained for 44 patients (69.8%) for periods ranging from three to 16 months (mean, eight months). Based on the Hunt and Hess grading scale, the patient population included 34 patients (54.0%) with unruptured aneurysms, 28 (44.4%) with Grade 1 aneurysms, one (1.6%) with Grade 2 aneurysms. The locations of the aneurysms included 25 (38.5%) at the distal to posterior inferior cerebellar artery (PICA), 22 (33.8%) at the proximal to PICA and 18 (27.7%) at the vertebral artery-posterior inferior cerebellar artery (VA-PICA). Of the 63 patients, 12 (19%) were women and 51 (81%) were men. The mean age at treatment was 41.7 years (range, six-77 yrs). Follow-up angiograms were obtained in 44 (69.8%) out of 63 patients. Complete or virtually complete thrombosis was confirmed on early post-treatment angiography in 39 (88.6%) out of 44 patients. A slight reduction in the size of the lesion was noted in three patients and there was a significant residual lesion in two (4.5%) patients. Clinical follow-up revealed 90.5% patients in the mRS 0-2 category, 4.8% patients in the mRS>2 category, and 4.8% patients had died (mRS 6). Three patients died of rebleeding (n = 1) or progressive mass effect/brainstem ischemia (n = 2). Ruptured and unruptured aneurysms of the vertebral artery can be well treated using endovascular techniques, overall long-term results were good in 90.5% of patients.
