Injury to the radial artery at the wrist or hand level is most commonly caused by a direct trauma or blunt force to the area, such as a fall onto an outstretched arm or a blow to the hand. It can also be caused by a laceration or cut to the hand.
Diagnosis of an injury to the radial artery at the wrist or hand level is typically made through a physical examination and medical history. Signs of injury may include swelling, redness, tenderness, or warmth in the area. A pulse may also be difficult to feel in the area due to decreased blood flow.
Other conditions that should be considered in the differential diagnosis of an injury to the radial artery include tendonitis, ligament sprains, fractures, and nerve injuries.
Treatment of an injury to the radial artery at the wrist or hand level will depend on the severity of the injury. Treatment may include rest, elevation, compression, and analgesics. Surgery may be necessary in cases of severe injury or laceration.
The prognosis for an injury to the radial artery at the wrist or hand level is generally good with proper treatment. If a laceration is severe, however, there can be long-term complications, such as decreased blood flow or even amputation of the affected limb.
