Adult Moyamoya Disease

<b><i>Background:</i></b> Patients with moyamoya disease often develop cerebral infarction and hemorrhage, but the ischemic and hemorrhagic subtypes are difficult to diagnose prior to disease onset. We aimed to differentiate the ischemic and hemorrhagic subtypes of moyamoya disease by analyzing the intralateral and perilateral ventricular arteries on the original axial magnetic resonance angiography (MRA) images. <b><i>Methods:</i></b> We retrospectively analyzed the intralateral and perilateral ventricular arteries on the original axial time-of-flight (TOF)-MRA images of 18 patients with hemorrhagic moyamoya disease, 25 patients with ischemic moyamoya disease, and 22 control patients with unruptured aneurysms. <b><i>Results:</i></b> There were significantly more intralateral and perilateral ventricular arteries on the original axial MRA images in the patients with hemorrhagic moyamoya disease (6.3 ± 2.7) than in those with ischemic moyamoya disease (0.8 ± 0.9) and those with unruptured aneurysms (0.4 ± 0.8). <b><i>Conclusion:</i></b> The intralateral and perilateral ventricular arteries on the original axial TOF-MRA images might suggest the hemorrhagic type of moyamoya disease prior to onset.

Before And After

Introduction —It is well known that surgical revascularization can improve cerebral hemodynamics and prevent further ischemic cerebrovascular events in moyamoya disease. However, a certain subgroup of patients repeats ischemic attacks even after surgery because of insufficient surgery or disease progression during follow-up periods. Hypothesis —Relevant designs and techniques in additional bypass surgery can resolve ischemic cerebrovascular events in patients with moyamoya disease refractory to previous bypass surgery. Methods —This study included totally 7 patients (9 hemispheres) with moyamoya disease refractory to previous bypass surgery. There were 5 children and 2 adults. They underwent previous bypass surgery in Japan and Europe 6 to 240 months before admission. Based on precise clinical and radiological analysis, cerebrovascular events were considered to occur because of insufficient bypass surgery in 5 patients and disease progression in the ipsilateral posterior cerebral artery in 2. Surgical strategies included wide craniotomy to cover the area where cerebral hemodynamics is still impaired and appropriate bypass procedures such as STA-MCA anastomosis, OA-PCA anastomosis, and indirect bypass. Using [123]I-IMP SPECT or [15]O-gas PET, cerebral hemodynamics was precisely examined before and after surgery Results —Postoperative course was uneventful and cerebral hemodynamics significantly improved in all 7 patients. Postoperative cerebral angiography revealed that additional bypass provided collateral blood flow to ischemic area before surgery. Ischemic cerebrovascular events rapidly resolved in 5 patients and gradually decreased in 2. Conclusion —This study strongly suggests adequate surgical design and procedures can resolve ischemic cerebrovascular events in patients with moyamoya disease refractory to previous bypass surgery.
