ICD-10: S85.172

The ICD-10 code S85.172 refers specifically to a laceration of the posterior tibial artery in the left leg. This code is part of the broader category of codes that describe injuries to blood vessels, particularly those affecting the lower extremities. Below is a detailed clinical description and relevant information regarding this specific injury.

Clinical Description

Definition

A laceration of the posterior tibial artery involves a tear or cut in this major artery, which runs down the back of the leg and supplies blood to the foot and lower leg. Such injuries can result from trauma, such as accidents, falls, or penetrating injuries.

Anatomy and Function

The posterior tibial artery is a crucial vessel that branches off from the popliteal artery behind the knee. It travels down the leg, providing blood supply to the posterior compartment of the leg and the plantar aspect of the foot. Damage to this artery can lead to significant complications, including ischemia (lack of blood flow), tissue necrosis, and potential loss of limb function.

Symptoms

Patients with a laceration of the posterior tibial artery may present with:
- Pain: Severe pain in the lower leg, particularly in the calf region.
- Swelling: Localized swelling around the injury site.
- Bruising: Discoloration of the skin due to bleeding under the surface.
- Pulsation Changes: Diminished or absent pulse in the posterior tibial artery, indicating compromised blood flow.
- Skin Changes: Coldness or paleness of the foot, which may suggest ischemia.

Diagnosis

Diagnosis typically involves:
- Physical Examination: Assessment of the injury, including checking for pulse and signs of circulation.
- Imaging Studies: Ultrasound or angiography may be used to visualize the extent of the injury and assess blood flow.
- CT Angiography: This may be employed for a more detailed view of the vascular structures.

Treatment

Management of a laceration of the posterior tibial artery may include:
- Surgical Intervention: Repair of the artery through suturing or grafting, depending on the severity of the laceration.
- Wound Care: Proper cleaning and dressing of the wound to prevent infection.
- Monitoring: Continuous assessment of limb perfusion and function post-surgery.
- Rehabilitation: Physical therapy may be necessary to restore function and strength in the affected leg.
