Q

To reduce the leg circulation time when doing large film from moral arteriography, blood pressure cuffs may be inflated to occlude both femoral arteries for 3 to 10 minutes. Then they are suddenly released, and the contrast is injected. The increased blood flow and reduced circulation time is due to
