Artery lumen diameter

WebDespite the marked difference in blood flow and flow velocity, calculated wall shear stress was the same in both the right (16 +/- 4 dynes/cm2) and left iliac vessels (15 +/- 2 dynes/cm2) because of a twofold increase in lumen diameter (p less than 0.001) of the right iliac artery. Shear stress in the aorta was also normal (12 +/- 2 dynes/cm2). WebResults: Diameters at landmarks of PAS were significantly larger in the ATBAD group. The lumen volume (V PAS) of PAS in the ATBAD group was significantly enlarged than that of the control group (124,659.07 ± 34,089.27 mm 3 vs 89,796.65 ± 30,334.40 mm 3; P < 0.001). Furthermore, the V PAS was positively correlated to diameters.
