Computational modelling of the cephalic arch with jugulocephalic vein variant predicts haemodynamic profiles in patients with brachiocephalic fistula.

Background: The cephalic vein is often used in for arteriovenous fistula creation; however, the cephalic vein variation is common. This study will propose new theoretical explanations for a new discovered variation of cephalic vein draining into external jugular vein with "T-junction" shape by means of 3D computational haemodynamic modelling, which may provide reference for clinical practice.

Materials And Methods: The precise measurements were conducted for the variant right cephalic vein draining into external jugular vein and for a normal right cephalic vein as a control.
