Summary of wall shear stress in proximal veins (in Pa)

	Patient	1	2	3	4
Near anastomosis	TAWSS	4.32	3.74	3.90	12.9
($<5$ mm)	$\overline{\tau }$	3.75	3.24	3.61	12.3
	Max WSS	9.08	9.02	7.50	26.8
Far from anastomosis	TAWSS	1.27	1.33 a	1.01	1.64
(25–30 mm)	$\overline{\tau }$	1.12	1.20 a	0.60	1.40
	Max WSS	2.42	3.10 a	2.94	3.58
	WSS-Poiseuille's law	0.74	1.19	0.58	0.73

Note: Shear by Poiseuille's law calculated by using the time-averaged flow rate and the diameter averaged along the vein axis.

^aFor patient 2, shear is averaged between 15–20 mm from anastomosis since the model vein is less than 25 mm long.
