Symptoms should be reproducible by exercising the arm.
A variation of the syndrome is the coronary SSS, which can only occur after coronary arter...

<bold>Figure 2.53.</bold> Schematic drawing of the blood flow in the vertebral and basilar arteries, as well in the circle of Willis, where the left proximal subclavian artery is occluded. In some individuals the blockage of the left subclavian artery causes a "subclavian steal syndrome" with neurologic symptoms. Note the direction of blood flow indicated by the arrows. Similar situation may be encountered with occlusion of the right subclavian artery and reversal of flow in the right vertebral a...
