Ulnar Artery Regurgitation

Ulnar artery regurgitation refers to the abnormal backward flow of blood in the ulnar artery, a major blood vessel running along the inner side of the forearm and supplying vital oxygenated blood to the hand. This reverse flow disrupts the usual circulation pattern and can lead to various complications.

Types of Ulnar Artery Regurgitation:

1. Acute Ulnar Artery Regurgitation:
   • Sudden onset of backward blood flow.
   • Often associated with traumatic injuries.
