Name of the Procedure:

Thrombectomy of Arterial or Venous Graft

Summary

A thrombectomy is a surgical procedure used to remove a blood clot (thrombus) from an artery or vein graft that is causing a blockage. This procedure involves the use of specialized instruments to extract the clot and restore normal blood flow.

Purpose

This procedure addresses the blockage of blood flow due to a blood clot in an arterial or venous graft. The primary goal is to restore adequate blood circulation to prevent tissue damage or organ failure and alleviate symptoms caused by the obstructed blood flow.

Indications

• Acute limb ischemia
• Pain and swelling due to venous graft occlusion
• Reduced blood flow that is detected through imaging studies
• Failed previous attempts with medication or less invasive procedures

Preparation

• Patients may need to fast for several hours before the procedure.
• Adjustments to blood-thinning medications may be required.
• Pre-procedure diagnostic tests such as ultrasounds, CT scans, or MRIs to locate the clot accurately.

Procedure Description

1. Anesthesia: General or regional anesthesia is administered.
2. Incision: A small incision is made near the graft site.
3. Insertion of Catheter: A catheter with a balloon or suction device is inserted into the vessel to locate the clot.
4. Clot Removal: The clot is extracted using suction, a mechanical device, or a clot-dissolving drug.
5. Verifying Flow: Blood flow is checked to ensure the vessel is clear.
6. Closing the Incision: The incision site is closed with sutures.

Specialized tools include catheters, guidewires, and imaging technology for real-time visualization.

Duration

The procedure typically takes between 1 to 3 hours.

Setting

Thrombectomies are generally performed in a hospital's vascular surgery suite or an interventional radiology department.

Personnel

• Vascular Surgeons or Interventional Radiologists
• Surgical Nurses
• Anesthesiologists

Risks and Complications

Common Risks:

• Infection at the incision site
• Bleeding
• Recurrent clots

Rare Risks:

• Damage to the blood vessel
• Kidney damage from contrast dye used during imaging
• Reaction to anesthesia

Management of complications involves antibiotics for infections and additional interventions for vessel damage or recurrent clots.

Benefits

• Restoration of normal blood flow
• Relief from pain and swelling
• Prevention of potential tissue damage or organ failure These benefits are typically realized immediately or shortly after the procedure.

Recovery

• Patients will need to stay in the hospital for monitoring, usually 1-2 days.
• Pain management will involve prescribed medications.
• Avoid strenuous activities for several weeks.
• Follow-up appointments for imaging and assessment of graft function.

Alternatives

• Medications such as anticoagulants or thrombolytics
• Angioplasty with or without stenting
• Bypass surgery

Each alternative has its pros and cons, depending on the patient's specific condition and overall health.

Patient Experience

During the procedure, patients will be under anesthesia and should not feel pain. Post-procedure, there may be discomfort at the incision site and the limb. Pain management will be provided. Full recovery may take a few weeks, during which patients should adhere to follow-up care instructions and activity restrictions to ensure optimal healing.
