title: Superficial temporal artery-to-middle cerebral artery bypass surgery for middle cerebral artery stenosis in a patient with cerebral autosomal-dominant arteriopathy with subcortical infarcts and leukoencephalopathy.
abstract: Cerebral autosomal-dominant arteriopathy with subcortical infarcts and leukoencephalopathy is a rare hereditary small vessel disease. Ischemic events are the main clinical manifestation of this condition. Here, we present a case in which superficial temporal artery-to-middle cerebral artery anastomosis was performed in a patient with cerebral autosomal-dominant arteriopathy with subcortical infarcts and leukoencephalopathy who developed cerebral infarctions caused by severe middle cerebral artery stenosis. Cerebral blood flow and cerebrovascular reactivity were effectively improved using double anastomoses. To our knowledge, surgical revascularization for patients with this condition has not yet been described in the literature. Superficial temporal artery-to-middle cerebral artery anastomosis is effective for patients with cerebral autosomal-dominant arteriopathy with subcortical infarcts and leukoencephalopathy who show marked regional cerebral hypoperfusion.
