( ESC Guideline 2019 )

13. 1.Acute VTE patients ( regardless of the size or
clinical severity of the VTE ) with Contraindications
to Anticoagulation
2. Recurrent PE despiteTherapeutic
Anticoagulation
3. IVC filter should be considered Individual basis for
patients with Intermediate-or high-risk PE who
tolerating therapeutic anticoagulation

IVC Filter
Reduce the short-term risk of subsequent PE
Increase long-term risk for DVT
No impact on Overall Mortality

Complications

19. IVC Filter Complications
1.Strut Fracture
2.Filter Migration
3.StrutEmbolization
4.Device Tilt
5.IVC penetration
6.Perforation of surrounding structures
7.PE, DVT & IVC thrombosis
Ref : Braunwald2022

20. IVC Filter Complications
To Avoid these Complications, IVC filters should be Retrievedas
soon as no longer necessary and after anticoagulation has been
safely started
Retrievable IVC filters can be removed Safely and Easily , yet up to
50% remain permanently indwellingRef : Braunwald2022

Deployment

24. Procedure
1.Preprocedural imaging : CDS of both lower extremities and IVC
2.Access: Contralateral to DVT location
3.IVC Filter location : Between IVC bifurcation ( Level of L5 Vertebra ) & Renal veins ( Level of L1-L2 disk )
4.Sheath: 6F
5.Long GW is prefferedfor advancement through Needle
6.Tube position ( 0 . 0 )
7.Injection via Femoral sheath for evaluation of Iliofemoral vein ( DSA Mode )
8.Advancement of long GW over femoral sheath
9.Replacement of femoral sheath with IVC Filter sheath ( 65 cm )
10.Sheath Inserion( Injection via Sheath , Note Renal Veins )
11.Put IVC filter from Femoral side inside the sheath ( Optease)
12.Push the IVC filter by Pusher
13.IVC Filter deployment in CINE ( table should not be moved )
14.Final Injection via Sheath ( DSA mode )
15.Sheath Removal

To Avoid Complications of In-Situ filters
Removal is Indicated when the filter is No longer Needed
