Name of the Procedure:

Common Name: Vena Cava Filter Insertion Technical/Medical Term: Inferior Vena Cava (IVC) Filter Placement

Summary

A vena cava filter insertion is a procedure where a small device is placed in the inferior vena cava (a large vein in the abdomen) to prevent blood clots from traveling to the lungs, which can cause a pulmonary embolism.

Purpose

Medical Conditions/Problems Addressed:

• Deep Vein Thrombosis (DVT)
• Prevention of Pulmonary Embolism (PE) in patients who cannot take anticoagulants

Goals/Expected Outcomes:

• Reduce the risk of pulmonary embolism
• Prevent migration of large clots to the lungs

Indications

Specific Symptoms/Conditions:

• Recurring DVT despite anticoagulation
• Contraindication to anticoagulant therapy
• Recent major surgery or trauma with high risk of DVT
• Severe trauma or injury requiring clot prevention

Patient Criteria:

• Unable to use blood thinners
• High risk of developing blood clots

Preparation

Pre-Procedure Instructions:

• Fast for a specified period before the procedure (usually 4-8 hours)
• Adjust or discontinue certain medications as advised by your doctor
• Undergo blood tests and imaging studies (e.g., ultrasound, CT scan) to assess clot risk and placement site

Procedure Description

1. Patient is positioned on the procedure table.
2. Local anesthesia is applied to the insertion site, usually in the neck or groin.
3. A small incision is made, and a catheter (a thin tube) is inserted into a large vein.
4. The catheter is guided to the inferior vena cava using X-ray imaging.
5. The vena cava filter is deployed through the catheter and positioned in the vena cava.
6. The catheter is removed, and the incision is closed.

Tools and Equipment:

• Catheter
• Vena Cava Filter
• X-ray or fluoroscopy machine

Anesthesia:

• Local anesthesia, sometimes with mild sedation

Duration

The procedure typically takes about 1-2 hours.

Setting

• Hospital or specialized outpatient clinic with radiology facilities

Personnel

• Interventional radiologist or vascular surgeon
• Radiology technicians
• Nurses
• Anesthesiologist or nurse anesthetist (if sedation is used)

Risks and Complications

Common Risks:

• Minor bleeding or bruising at the insertion site
• Infection

Rare Risks:

• Filter migration or misplacement
• Breakage of the filter
• Blockage of the vena cava
• Venous injury

Management:

• Monitoring and addressing complications as they arise
• Possible removal or repositioning of the filter if necessary

Benefits

Expected Benefits:

• Significant reduction in the risk of pulmonary embolism
• Immediate prevention of large clots reaching the lungs
• Long-term protection when anticoagulants cannot be used

Realization Time:

• Immediate to short-term (<24 hours after placement)

Recovery

Post-Procedure Care:

• Monitor insertion site for signs of infection or extensive bleeding
• Resume normal activities gradually as advised
• Follow-up imaging tests to ensure proper placement and function of the filter

Expected Recovery Time:

• Few days to a week with minimal restrictions
• Follow-up visits may be required to assess the filter and overall health

Alternatives

Available Options:

• Anticoagulant medications
• Thrombolytic therapy (clot-dissolving drugs)

Pros and Cons:

• Anticoagulants: effective but unsuitable for some due to bleeding risk.
• Thrombolytic Therapy: effective but generally limited to acute clot situations; higher bleeding risk.

Patient Experience

During the Procedure:

• Mild discomfort from local anesthesia injection
• Pressure or slight pain during catheter insertion

After the Procedure:

• Possible mild pain or tenderness at the insertion site
• Fatigue or minor soreness, typically manageable with over-the-counter pain relievers
• Regular activities can usually be resumed within a few days, following medical advice.

Pain Management and Comfort Measures:

• Over-the-counter pain relievers (e.g., acetaminophen)
• Application of ice packs to the insertion site
