Figure 1: Changes in Femoral Angiographic Lumen Size

(A, B) The angiographic lumen size of the femoral artery (white arrows) (from the site of injury to the popliteal artery) was measured before and after randomized treatments. The degree of CIV was similar in the pigs pre-treated with L-NAME (B). CIV = catheter-induced vasospasm; L-NAME = N (ω)-nitro-L-arginine methyl ester; MB = microbubble; US = ultrasound.
