    Collapse Overview
    Christopher Dowd, MD, is a Professor of Radiology and Biomedical Imaging, Neurological Surgery, Neurology, and Anesthesia and Preoperative Care and Co-Director of Birthmarks and Vascular Anomalies Center at the University of California, San Francisco. He specializes in the diagnosis, management and treatment of cerebrovascular diseases of the brain/spinal cord and of vascular birthmarks. Dr. Dowd earned his medical degree from the University of Virginia, Charlottesville in 1983, and completed his residency in Diagnostic Radiology at the University of California, San Diego, followed by a fellowship in Neuroradiology and Interventional Neuroradiology at UCSF.

    Dr. Dowd’s primary research interests include: endovascular treatment of intracranial aneurysms endovascular treatment of aneurysmal subarachnoid hemorrhage-induced vasospasm, endovascular treatment of cutaneous vascular birthmarks, human fetal tracheal balloon occlusion in the treatment of congenital diaphragmatic hernias, endovascular treatment of acute dural sinus thrombosis, endovascular treatment of vein of galen malformations, preoperative tumor embolization, the novel treatment of chemoinfusion for retinoblastomas, and endovascular therapy for brain AVMs and dural carotid-cavernous fistulas.

    Dr. Dowd has served as the Primary Investigator and Co-Investigator of many IRB/CHR approved research projects. He has published 178 articles, written over 300 scientific abstracts, and 58 book chapters dedicated to his research.
