Show Information

Subclavian steal syndrome is a disorder caused by reversed blood flow in one of the two major arteries that flow through the torso. When a critical artery becomes narrowed, blood flow by-passes the area and this usually results in not enough blood reaching the brain.

Although the condition is rare, it presents with symptoms similar to a stroke and should be first in a differential diagnosis once a stroke is ruled out.

The condition can usually be corrected by removing the occlusion that caused the blood flow restriction.
