Current Management of DVT Diagnosis of DVT IVC Filter:

•Contraind. to Anticoag.

•Protection during Lysis Anticoagulation

Distal (Calf Vein)

Serial DUS to Exclude

Propagation

Iliac/CFV

•Pharmacologic Lysis (no contraind.)

•Mechanical Thrombectomy

•(+ Lysis)

•Iliac Stent (if residual stenosis)

•Surgical Thrombectomy

•Failed Lysis

•Contraind. to Lysis

•Failed Thrombectomy

So, Why Consider Intervention? • Here is your challenge:

– There are so many physicians who believe that they are experts in the management of DVT

– Their perception?

• Patients do quite well with standard anticoagulation

– And now with NOACs????

• We can keep patients out of the hospital

– (Who would argue with that?)

• Why incur the risks associated with intervention?

• Why incur the costs associated with intervention?

• Is this all trumped up to generate another procedure for interventionists?

Goals of endovascular therapy for DVT

• More rapid lysis via local administration of drug

• Relieve acute pain and edema

• Prevent PE and recurrent thrombosis

• Prevent post-thrombotic syndrome

• Restore vessel patency

• Preserve valve function

• Correct underlying anatomic lesions

Page 6: Intervention for Deep Venous Thrombosis and Pulmonary Embolus€¦ · Intervention for Deep Venous Thrombosis and Pulmonary Embolus Michael R. Jaff, DO Paul and Phyllis Fireman Endowed

Indications for Endovascular Venous Intervention

• Phlegmasia cerulea dolens

• Extensive or proximal DVT: IVC, iliofemoral

– Young, highly-functional ptshigh risk of PTS

– Symptomatic IVC filter occlusion

– Early intervention is best, but benefit may still be derived months after acute occlusion

• High risk for fatal PE

• Propagation of DVT despite conventional therapy

• High likelihood of underlying anatomic lesion

– May-Thurner syndrome (MTS)

– Compression by pelvic tumor

– Prior pelvic DVT

Percutaneous mechanical thrombectomy: Advantages vs. CDT

• Shorter treatment time to patency?

• Potentiator of thrombolytic therapy for subacute or chronic thrombus?

• Application when to lysis contraindicated?

• Cheaper?

• Safer?

The ATTRACT Trial • Acute Venous Thrombosis: Thrombus Removal with Adjunctive

Catheter-Directed Thrombolysis

– NHLBI-funded, Phase III, open-label, multicenter RCT

– Pharmacomechanical Catheter-Directed Thrombolysis

– 692 patients with symptomatic, acute proximal DVT

– 28 U.S. Centers, currently enrolling

– PI = Dr. Suresh Vedantham (Washington University)

– Study Chair = Dr. Samuel Z. Goldhaber (Harvard)

SVS/AVF Guidelines

Guideline Grade Recommendation Quality of Evidence

Early Thrombus Removal in the following scenarios: --First episode of acute iliofem DVT --Symptoms <14 days --Low Bleeding Risk --Ambulatory, good functional capacity, ‘acceptable’ life expectancy

2-Weak C-Low/very low

Early Thrombus Removal in Phlegmasia Cerulea Dolens

1-Strong A-High

Percutaneous Techniques Preferred as Thrombus Removal Strategy

2-Weak C-Low/very low

Pharmacomechanical thrombolysis preferred to Catheter-Directed Thrombolysis

2-Weak C-Low/very low

Highlights from the AHA Guidelines Iliofemoral Deep Venous Thrombosis

• Defined as complete or partial thrombosis of any segment of the iliac vein or the common femoral vein, with or without involvement of other lower extremity veins or inferior vena cava.

Circulation 2011

Page 17: Intervention for Deep Venous Thrombosis and Pulmonary Embolus€¦ · Intervention for Deep Venous Thrombosis and Pulmonary Embolus Michael R. Jaff, DO Paul and Phyllis Fireman Endowed

Intervention for Deep Venous Thrombosis

• Deep Venous Thrombosis

– Anticoagulation does not prevent development of post-thrombotic venous insufficiency

– Morbidity of post-thrombotic venous insufficiency is significant and costly

– Consider endovenous intervention for iliofemoral DVT, advanced symptoms, and low bleeding risk

– Experienced interventionist is critical
