1. Patient Preparation
The access site, typically the right internal jugular or common femoral vein—is prepared and covered sterilely while the patient is in a supine position. When necessary, conscious sedation and local anesthetic are given.

procedure steps
2. Venous Access
A guidewire is advanced through the needle into the venous system up to the inferior vena cava under fluoroscopic guidance after a needle is put into the chosen vein (femoral or jugular) using ultrasound guidance.
3. First Venography
In order to see the anatomy of the vena cava, verify patency, rule out thrombus, and locate the renal vein to direct filter implantation, a catheter is inserted into the IVC and contrast dye is administered.
4. Preparing the filter and inserting the sheath
To create a conduit for the filter delivery system, a vascular sheath is positioned over the guidewire. The manufacturer's instructions are followed when loading and preparing the IVC filter on its delivery device.
5. Filter Positioning and Advancement
Usually infrarenal (below renal veins), the filter delivery system is progressed via the sheath into the IVC to the proper level. Fluoroscopy is used to confirm proper placement.
6. Deployment of Filters
The filter expands and attaches itself to the vena cava wall after being freed from the delivery system. Deployment is closely monitored to prevent tilting or migration.
7. Final Venography and Verification
To verify filter location, IVC and renal vein extension, and patency, post-deployment venography is carried out.
8. Hemostasis and Sheath Removal
The guidewire and delivery sheath are taken off. Manual compression or closure devices are used to achieve hemostasis at the venous puncture site.
9. After-Procedure Care
The patient is usually released on anticoagulant treatment or in accordance with therapeutic indication after being observed for problems including bleeding or thrombosis at the access site.

suitable for
Patients with Venous Thromboembolism (VTE) Who Cannot Tolerate Anticoagulation
Patients with deep vein thrombosis (DVT) or pulmonary embolism (PE) who are not eligible for anticoagulant medication because of bleeding risk or other medical conditions frequently have IVC filters implanted.
Patients with Recurrent VTE Despite Anticoagulation
In order to stop emboli from entering the lungs, patients who experience recurrent PE or DVT despite receiving sufficient anticoagulation may benefit from filter implantation.
Prophylaxis in High-Risk Trauma or Surgical Patients
IVC filters may be administered as a preventive measure to patients who are immobilized as a result of trauma, major surgery, or who are at high risk of developing VTE and cannot be anticoagulated.
Patients with Hemodynamic Instability and Massive PE
As a temporary approach to stop further emboli in critically ill patients while definitive treatment is being administered.
Patients Having Specific High-Risk Procedures
those having spinal surgery, bariatric surgery, or other procedures that are contraindicated for anticoagulation and have an increased risk of VTE.
Patients with big Clot Burden in Lower Extremity Veins or IVC
Filters lower the risk of PE by preventing big emboli from moving from the legs or pelvis to the lungs.
Permanent or Temporary Use Clinical Scenario-Based
Permanent filters may be used for long-term anticoagulation contraindications, while retrievable filters are frequently employed when anticoagulation is anticipated to be temporarily stopped.
benefits
Pulmonary Embolism Prevention
IVC filters greatly lower the risk of potentially deadly PE in patients who are unable to take anticoagulation or who have not responded to pharmacological therapy by successfully capturing big venous clots and preventing them from reaching the lungs.
Life-Saving in Acute High-Risk Environments
Critical in patients with acute DVT/PE who cannot be anticoagulated because of bleeding hazards or recent surgery, trauma victims, or immobilized patients.
Permanent or Temporary Protection
While permanent filters offer long-term care for certain patients, retrievable filters enable temporary protection at times when anticoagulation is contraindicated.
Decrease in PE Recurrence
Filters may be helpful in preventing additional embolic events in patients who have recurrent thromboembolism despite anticoagulation.
Enhancement of Patient Results
When incorporated into comprehensive venous thromboembolism management, the use of IVC filters in carefully chosen patients is linked to improved overall clinical outcomes and a reduction in mortality from acute PE in hospital settings.
post-treatment recovery
Recuperation and Monitoring in the Hospital
After the procedure, the majority of patients are monitored for a few hours before being released the same day.
Vital signs, the site of the puncture for bleeding, and general health are tracked.
Activity and Wound Care
If accessed by a neck vein, it is typical to resume regular activities within a day.
To prevent bleeding or problems at the puncture site, refrain from driving, hard lifting, and vigorous activity for approximately 48 hours after accessing the femoral (groin) vein.
The dressing can be taken off after the puncture site has been kept dry and clean for 24 to 48 hours.
Typical Symptoms Following Procedures
It is normal to experience mild bruising, discomfort, and swelling at the access site; these symptoms usually go away in a few days.
You can utilize over-the-counter painkillers.
Monitoring and Filtering
To keep an eye on the filter's location and functionality, routine follow-up imaging is advised.
In order to minimize long-term consequences, retrievable filters should ideally be removed once the danger of pulmonary embolism has decreased, usually within 90 days.
Go Back to Your Everyday Life
After the treatment, most patients soon return to their regular activities, paying close attention to the danger of bleeding.
