A Jugulo-Cephalico-Subclavian Venous Complex Associated With a Double Fenestration of the External Jugular Vein: A Dissection Report

The purpose of the present cadaveric report is to describe the unique combination of 2 rare variations of the venous system. A rare anatomic variation was discovered during the dissection of a 70-year-old donated male cadaver. This unique case revealed an atypical supraclavicular course and termination of the cephalic vein at the confluence of the external, internal, and subclavian veins, coexisting with the external jugular vein’s double fenestration before its confluence. This unusual finding, the jugulo-cephalico-subclavian venous complex, holds significant clinical value.
