Abstract

Moyamoya disease (MMD) is a rare occlusive cerebrovascular disease that mainly presents in children as cerebral ischemia. Prompt treatment with either a direct or indirect revascularization procedure is necessary for children with MMD in order to prevent repeated ischemic events. We herein present our experience with combined direct and indirect bypass surgery for the treatment of pediatric MMD as well as our uniquely designed perioperative protocol. Twenty-three patients with MMD, aged between 2 and 16 years old (mean 9.36), underwent 38 combined bypass procedures between 2008 and 2015. All patients underwent single superficial temporal artery-middle cerebral artery (STA-MCA) anastomosis combined with encephalo-duro-myo-synangiosis (EDMS). The perioperative management protocol was stratified into two unique eras: the first era with normotensive care and the second era with strict blood pressure control (systolic 100–130 mmHg) and routine aspirin administration. Patients were followed after surgery for a period ranging between 3 and 131 months (mean 77 months) in yearly clinical and radiological follow-ups. Three postoperative complications were observed: two cases of cerebral hyperperfusion (2/38, 5.3 %) and one case of perioperative minor stroke (1/38, 2.6 %), two of which were in the first era. No strokes, either ischemic or hemorrhagic, were observed in the follow-up period, and the activity of daily living as shown by the modified Rankin Scale improved in 20 patients, with no deterioration being observed in any of our patients. STA-MCA bypass with EDMS is safe and effective for the management of pediatric MMD and provides long-term favorable outcomes. Perioperative care with blood pressure control combined with the administration of aspirin may reduce the potential risk of surgical complications.
