Figure 1.

Angiography before and after treatment. Angiographic images showing the status of peripheral vessels in fingers. The pre-treatment picture show open arteries in the right forearm. The digital arteries in the hand are displayed extraordinary gracile. The blood-flow in the arteries are reduced, even if the fingers are stimulated with mild heat or undergoing exercise. The post-treatment images still show reduced peripheral vascularisation, however, the digital arteries are more vasodilated and less gracile compared with the pre-treatment display.
