ICD-10: S35.515

The ICD-10 code S35.515 specifically refers to an injury of the left iliac vein. This code is part of the broader category of codes that classify injuries to the iliac arteries and veins, which are critical components of the vascular system in the pelvis.

Clinical Description

Definition

The left iliac vein is a major blood vessel that drains blood from the left lower limb and pelvic region back to the heart. An injury to this vein can result from various causes, including trauma, surgical procedures, or pathological conditions such as thrombosis.

Types of Injuries

Injuries to the left iliac vein can be classified into several types:
- Lacerations: These are cuts or tears in the vein, which can lead to significant bleeding.
- Contusions: Bruising of the vein may occur without a complete tear, potentially affecting blood flow.
- Thrombosis: A clot may form within the vein, obstructing blood flow and leading to complications such as swelling and pain.

Symptoms

Patients with an injury to the left iliac vein may present with:
- Swelling: Particularly in the left leg or pelvic area due to impaired venous return.
- Pain: Localized pain in the groin or lower abdomen.
- Discoloration: Changes in skin color due to blood pooling.
- Signs of Shock: In severe cases, significant blood loss may lead to symptoms of shock, including rapid heartbeat, low blood pressure, and confusion.
