Clinical features and endovascular treatment of moyamoya disease with intracranial aneurysms

Abstract

Objective To investigate the clinical imaging features and methods of endovascular embolization of moyamoya disease with intracranial blood flow-related aneurysms. Methods The clinical features, imaging features and endovascular embolization treatment of 7 patients with moyamoya disease and intracranial aneurysm diagnosed by digital subtraction angiography (DSA) were analyzed retrospectively. Two of them underwent ventricular drainage after embolization, 1 underwent roofing of temporal muscle, and 1 underwent extra- and intra-cranial vascular bypass and roofing of temporal muscle. Results Five of 7 patients showed subarachnoid hemorrhage, 2 showed cerebral parenchymal hemorrhage broken into ventricles; of the 7 patients with 8 aneurysms, 6 were the main artery aneurysms and 2 were peripheral artery aneurysms. They were all treated with endovascular embolization. The clinical symptoms of the patients had different degrees of recovery or improvement, 5 of them could work and learn normally, 1 had mild hemiplegia, but he could take care of himself, 1 patient had severer lower limb movement disorder on one side and he could almost take care of himself. No recurrence and new aneurysms were found after following up with DSA. Conclusion Blood flow-related aneurysms cause by moyamoya disease may result in different types of clinical and imaging manifestations. Endovascular technique is an effective method for the treatment of blood flow-related moyamoya disease. Key words: Moyamoya disease; Aneurysm; Endovascular treatment
