Management of Cerebral Proliferative Angiopathy with Indirect Revascularization: A Case Report

Abstract

A 43-year-old man presented with cerebral proliferative angiopathy (CPA) that manifested as convulsions and transient ischemic attacks (TIA). Single-photon emission computed tomography imaging demonstrated decreased perfusion around the nidus; therefore, indirect revascularization was performed. Cerebral angiography, performed 3 years after the surgery, demonstrated no neovascularization, although the patient did not develop convulsions or TIA after anticonvulsant treatment. Indirect revascularization may not be effective to sufficiently improve cerebral blood flow, and hence, direct revascularization may be a better treatment option for middle-aged individuals with CPA.
