✓ Eleven cases of moyamoya disease refractory to indirect non-anastomotic revascularization, including encephalomyosynangiosis in two, encephaloduroarteriosynangiosis in seven, and encephalomyoarteriosynangiosis in two, are described. The patients suffered from recurrent cerebral ischemic symptoms, and further operative intervention, including superficial temporal artery-middle cerebral artery anastomosis and intracranial omental transplantation, was performed. The choice of operative maneuver depended on the availability of scalp arteries and on the nature of the ischemic symptoms. Although indirect non-anastomotic revascularization procedures have the advantage of technical ease and most patients respond to these procedures alone, there are some patients like the 11 presented here who are not cured by such procedures. In such cases, direct anastomotic revascularization is necessary for the prevention of stroke.

✓ The authors describe a “stabilizing hemostatic clamp” of their own design for use in end-to-side anastomosis. Its application facilitates simultaneous stabilization and hemostatis of the cortical artery at the site where anastomosis is to be performed. Using this instrument, the authors have performed anastomosis of the superficial temporal artery with a branch of the middle cerebral artery in 60 patients. On evaluation of the clinical effects of the treatment and results of control angiography, and taking into account the authors' relatively small experience with this type of surgical treatment, they conclude that their new clamp facilitates this form of surgery.

✓ The involvement of the posterior circulation in moyamoya disease was studied in 178 patients. Forty-three had several types of disturbance such as visual field defect, decreased visual acuity, episodes of blindness, and scintillating scotomata. Most of these symptoms were attributed to occlusive lesions in the posterior circulation. Visual disturbances were seen more often in patients with a juvenile onset than in cases of adult onset. Superficial temporal artery (STA) to middle cerebral artery (MCA) anastomosis and encephalomyosynangiosis (EMS) improved the cerebral perfusion both in the anterior and posterior circulation by redistribution of blood. In most cases, the visual symptoms subsided or were stabilized after STA-MCA anastomosis and EMS. These surgical procedures did not, however, lead to direct revascularization in cases of ischemia in the visual cortex. In five patients with impending blindness, transplantation of the omentum to the occipital lobe led to improved vision.

Flow 800

The surgical treatment of moyamoya disease is heavily reliant upon a real-time understanding of cerebral hemodynamics. The application of FLOW 800 allows the surgeon to semiquantify the degree of perfusion to the cerebral cortex following extracranial-to-intracranial (EC-IC) bypass surgery. The authors present three illustrative cases demonstrating common intraoperative findings prior to and following anastomosis using FLOW 800. All patients were diagnosed by catheter angiogram with moyamoya disease and noninvasive imaging demonstrating hemispheric hypoperfusion. Superficial temporal artery (STA)–to–middle cerebral artery (MCA or M4) bypasses were performed to augment intracranial perfusion. The patients tolerated the procedures well and were discharged without event in stable neurological condition. The video can be found here: https://stream.cadmore.media/r10.3171/2021.10.FOCVID21191

Object. In moyamoya disease (MMD), ischemic events are usually precipitated by activities associated with hyperventilation or physical strain. The authors report on four patients with a rare combination of Graves disease—associated thyrotoxicosis and MMD, whose cerebrovascular ischemic events occurred while in a thyrotoxic state. The clinical correlation between MMD and Graves' thyrotoxicosis, and outcome after surgical intervention are described. Methods. Four young women, ages 22 to 25 years, presented with profound cerebrovascular ischemic accidents. They had clinical and radiological features consistent with the diagnosis of MMD and were in the active thyrotoxic state of Graves disease. To prevent a future ischemic event, patients underwent superficial temporal artery—middle cerebral artery anastomosis combined with encephalomyosynangiosis or encephaloduroarteriosynangiosis after normalization of their hormonal conditions. All patients have been neurologically stable since revascularization procedures and lead a normal daily life. In patients with MMD, cerebrovascular ischemic events may be precipitated by thyrotoxicosis. One possible pathomechanism of cerebrovascular ischemic aggravation in the thyrotoxic state may be a hemodynamic compromise induced by an excessive increase in the cerebral metabolism and oxygen demand over the compensation of the cerebral blood flow deficit through collateral supply in MMD. Conclusions. Surgical revascularization after optimal control of thyrotoxicosis is thought to be an appropriate treatment in patients with MMD concurrent with Graves disease for the prevention of further ischemic events, especially in those with impaired cerebral perfusion and cerebral ischemic symptoms.

✓ Superficial temporal artery to middle cerebral artery (STA-MCA) anastomoses were examined at autopsy in two patients who survived 2 years and 5½ years, respectively, after the cerebral revascularization procedure. Identification of the actual anastomotic sites at autopsy was rendered impossible because of marked fibrosis in the region of the surgery. However, in both patients intimal fibrosis and medial damage were noted in the STA immediately adjacent to the anastomosis. In the patient who survived 2 years, the lumen of the STA was only slightly compromised by these changes, but in the patient who survived 5½ years, the artery was almost totally occluded. The MCA's adjacent to the anastomosis were widely patent and showed focal areas of intimal hyperplasia with no abnormalities of the media.

Object. The authors evaluated the effects of superficial temporal artery—middle cerebral artery (STA—MCA) bypass in the prevention of future stroke, including rebleeding or an ischemic event, in patients suffering from hemorrhagic moyamoya disease by comparing this method with indirect bypass and conservative treatment.Methods. Twenty-two patients who had hemorrhagic moyamoya disease but no aneurysm comprised the study group. These patients' clinical charts were examined with respect to their treatment and clinical course after an initial hemorrhagic episode. The mean age of the patients was 43 years and the follow-up period ranged from 0.8 to 15.1 years, with a mean of 8 years. Eleven patients (50%) were conservatively treated. Among the 11 patients who were surgically treated, STA—MCA bypass was performed in six patients (27%) and encephaloduroarteriosynangiosis (EDAS) in the other five patients (23%). Nine patients (41%) presented with an ischemic or rebleeding event during the follow-up period. The incidence of future stroke events in patients who had undergone an STA—MCA bypass was significantly lower (p < 0.05) than that in patients who had been treated conservatively or with EDAS. Kaplan—Meier plots comparing stroke-free times in patients treated with direct bypass and those in patients who conservatively or with indirect bypass showed a significant difference (p < 0.05) in favor of direct bypass.Conclusions. The effect of STA—MCA bypass on the prevention of recurrent hemorrhage or an ischemic event in patients with hemorrhagic moyamoya disease has been statistically confirmed in this study.

✓ Between 1974 and 1982, an anastomosis between a pedicle of the superficial temporal artery (STA) and a cortical branch of the middle cerebral artery (MCA) was performed in 163 carotid systems in 157 patients for internal carotid artery occlusion in whom postoperative angiograms were available for analysis. The angiographic opacification of the arterial system was correlated with the patient's preoperative neurological function and stroke in the follow-up period. From this analysis, the following observations were made: 1) 96% of bypasses were patent; 2) 80% of bypasses achieved a high or medium MCA filling score; 3) there was hypertrophy of the STA in 70% of the cases; 4) greater bypass filling occurred in hemispheres with nonvisualized preoperative collateral circulation than in those with readily visualized collateral flow; 5) a meaningful correlation between angiographically assessed postoperative bypass function and stroke rate was not possible because only four patients suffered an ipsilateral hemispheric stroke in the 8-year follow-up period; and 6) patients who were neurologically unstable before the procedure were at greatest risk for a stroke in the follow-up period. It is apparent that objective analysis of the effectiveness of an STA-MCA bypass, or any other form of extracranial bypass, must await the development of new diagnostic studies in which high-resolution three-dimensional quantification of cerebral blood flow is possible. These studies will necessarily be correlated with preoperative and follow-up clinical data.
