I will try again: There are several cause of arterial occlusions. There are degrees of arterial blockage. If a clot moves- embolize s it can obstruct multiple vessels and branches causing more tissue to be under circulated-ischemic. The remaining question is why the radial clotted: embolus, trauma, needle sticks, thoracic outlet and aneurysm. Need exam. Doppler helps define the location but not the cause.
