title: Duplication of the straight sinus. An angiographic study.
abstract: Duplication of the straight sinus is often noted in the venous phase of carotid angiograms. Since this vascular anomaly is rarely described in the literature, the authors present its incidence in a series of 700 cases, and consider its embryological origins and clinical significance.
