“…[3] Although the endovascular technique is an effective treatment, some complications have been reported. [378] We previously reported a patient with a VA dissecting aneurysm distal to PICA who showed cerebellar hemorrhage 23 h after embolization.

“…[15] Some complications related to VA occlusion have been reported. [378] In this report, we describe a patient who showed cerebellar hemorrhage during hypertensive and antiplatelet therapies for vasospasm after embolization of a VA dissecting aneurysm proximal to the posterior inferior cerebellar artery (PICA). We discuss the mechanism of cerebellar hemorrhage and perioperative management of patients with a ruptured VA dissecting aneurysm after occlusion of the parent artery.…”

Background:Some complications related to vertebral artery occlusion by endovascular technique have been reported. However, cerebellar hemorrhage after vertebral artery occlusion in subacute phase is rare. In this report, we describe a patient who showed cerebellar hemorrhage during hypertensive therapy for vasospasm after embolization of a vertebral dissecting aneurysm.Case Description:A 56-year-old female with a ruptured vertebral dissecting aneurysm proximal to the posterior inferior cerebellar artery developed cerebellar hemorrhage 15 days after embolization of the vertebral artery, including the dissected site. In this patient, the preserved posterior inferior cerebellar artery fed by retrograde blood flow might have been hemodynamically stressed during hypertensive and antiplatelet therapies for subarachnoid hemorrhage, resulting in cerebellar hemorrhage.Conclusion:Although cerebellar hemorrhage is not prone to occur in the nonacute stage of embolization of the vertebral artery, it should be taken into consideration that cerebellar hemorrhage may occur during hypertensive treatment.

“…Therefore, many perforating arteries are directly occluded and ischemic complications are more likely to occur. Additionally, patients may experience rebleeding after proximal clipping 4,20 . Therefore, in the recent cases in our series, we embolized cranial nerve palsies were found to resolve completely within six months 1 .…”

This paper analyzes the success of endovascular management of ruptured and unruptured 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 posttreatment 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.
