Vascular injury are problems with arteries and veins. Arteries are pipes that bring blood from the heart to the fingers. Veins are pipes that return the used blood back to the heart and lungs. At the wrist, the radial and ulnar arteries bring blood into the hand. These arteries connect into two arches that branch out to the supply blood to each of the finger.
Causes of vascular disorder can be any of the following:
- Traumatic injury, mainly laceration
- Compressive, which occur when the pipes flatten
Symptoms of vascular disorders can include:
- Abnormal color changes in the fingertips
- Numbness or tingling of the fingertips
- Cool or cold fingers and/ or hands.
