Name of the Procedure:

Ligation of Inferior Vena Cava (IVC Ligation)

Summary

Ligation of the inferior vena cava is a surgical procedure where the inferior vena cava, a large vein that carries blood from the lower body to the heart, is tied off or closed. This procedure is typically performed to prevent life-threatening blood clots from traveling to the lungs.

Purpose

The procedure addresses the risk of blood clots, known as deep vein thrombosis (DVT), traveling to the lungs and causing a pulmonary embolism. The goal is to prevent these blood clots from reaching the heart and lungs, thereby reducing the risk of serious complications or death.

Indications

• Patients with recurrent DVT despite anticoagulation therapy
• Patients who cannot take anticoagulation medication due to bleeding risks
• Large, life-threatening blood clots that need immediate intervention
• Certain types of trauma or injuries that risk clot formation

Preparation

• Patients may be instructed to fast for a specific period before the surgery.
• Adjustments to medications, especially blood thinners, may be required.
• Preoperative tests like blood work, imaging studies, and a cardiovascular assessment may be conducted.

Procedure Description

1. The patient is placed under general anesthesia or regional anesthesia.
2. An incision is made in the abdomen to access the inferior vena cava.
3. The inferior vena cava is identified and isolated from surrounding tissues.
4. A ligature (tie) is placed around the vein to close it off either permanently or temporarily.
5. The incision is then closed in layers and dressed.

Tools and equipment used include scalpels, clamps, sutures, and specialized ligation devices.

Duration

The procedure typically takes 1 to 2 hours, depending on the patient's condition and the complexity of the surgery.

Setting

The procedure is performed in a hospital setting, specifically in an operating room.

Personnel

• A vascular surgeon or a cardiothoracic surgeon
• Surgical nurses
• An anesthesiologist
• Possibly a surgical assistant

Risks and Complications

• Infection at the incision site
• Bleeding or hematoma
• Blood clots forming elsewhere
• Injury to surrounding organs or blood vessels
• Anesthesia-related risks
• Potential for long-term swelling in the legs

Benefits

• Prevents blood clots from traveling to the lungs, reducing the risk of pulmonary embolism.
• Provides an alternative for patients who cannot use anticoagulants.
• The benefits are immediate in terms of reducing clot-related risks.

Recovery

• Post-operative monitoring in the hospital for 1-2 days.
• Pain management with prescribed medications.
• Instructions to avoid heavy lifting and strenuous activities for several weeks.
• Follow-up appointments to monitor healing and effectiveness of the procedure.

Alternatives

• Anticoagulant medication (blood thinners)
• Insertion of an inferior vena cava filter (IVC filter) to catch clots
• Thrombolytic therapy to dissolve existing clots

Pros and cons of alternatives:

• Anticoagulants are less invasive but may not be suitable for all patients.
• IVC filter insertion is less invasive but carries its own risks and may need to be removed later.
• Thrombolytic therapy can dissolve clots but may increase bleeding risks.

Patient Experience

During the procedure, the patient will be under anesthesia and not feel anything. After the procedure, there may be some pain and discomfort at the incision site, which can be managed with medication. Patients may feel slightly groggy or disoriented as the anesthesia wears off. Full recovery can take several weeks, during which activity will be limited to ensure proper healing.
