The micro CT scans clarified that when the hind limb of a mouse suffers from ischemia, the inferior
gluteal artery expands and functions as a bypass.
Even in human patients with peripheral obstructive artery disease, detailed diagnostic images revealed that the inferior
gluteal artery expands in response to vascular stenosis (vessel hardening).
«Two things are believed to be the causes of the inhibited development of the inferior
gluteal artery in humans,» said Assistant Professor Yuichiro Arima, who led the study.
Importantly, the researchers also showed that the inferior
gluteal artery of the mouse extends to the lower hind leg area, whereas the human inferior
gluteal artery terminates much earlier at the buttock.
