Moyamoya disease is a rare cerebrovascular disorder characterized by progressive stenosis of the terminal segments of the internal carotid arteries and the development of collateral vessels with a characteristic “puff of smoke” appearance. In this case report, a 36-year-old female patient with a known diagnosis of Moyamoya disease underwent on-pump coronary artery bypass grafting (CABG) for significant stenosis in the LAD and CX arteries. Special attention was paid to intraoperative cerebral protection strategies, including maintenance of pulsatile flow, higher hematocrit levels, adequate mean arterial pressure, and avoidance of deep hypothermia. No neuromonitoring modalities were used, as they were not routinely available in our institution. No instances of vasculitis were detected in the LIMA and saphenous vein grafts. The postoperative course was uneventful. This case demonstrates the safe application of surgical revascularization in patients with coexisting Moyamoya disease and coronary artery disease.
