What is Venous
Thromboembolism
(VTE)?
VTE is a term referring to blood clots in the veins, is an underdiagnosed and serious medical condition
that affects nearly 900,000 Americans each year.1

When a venous blood clot forms, it can limit or completely block the flow of blood within the body. There are two types of clots that together are known as VTE: Deep Vein Thrombosis and Pulmonary Embolism.
What is Venous Thromboembolism?
Deep Vein Thrombosis (DVT)
What is it?
A DVT occurs when a blood clot, or thrombus, forms in one or more of the deep veins in the body, usually in the lower legs, thigh, or pelvis. In some cases, DVT can occur in other areas, such as the arms.
Why is it dangerous?
The formation of a clot can damage valves and walls of veins. If clot remains in the veins for a long period of time, this can result in long-term consequences known as postthrombotic syndrome (PTS). PTS impacts up to 50% of DVT2 patients with life-debilitating symptoms such as severe pain, swelling and discoloration of the affected limb.
Pulmonary Embolism (PE)
What is it?
A serious complication of DVT that occurs when part of a blood clot breaks off and travels through the bloodstream to the pulmonary arteries.
Why is it dangerous?
A PE blocks blood flow to the lungs, causing increased stress on the heart and decreased oxygen levels in the body. As the heart works harder to pump blood past the clot, it can become enlarged, with greater risk of failure. PE is the third leading cause of cardiovascular death in the US after heart attack and stroke.
WHAT ARE THE
WARNING SIGNS
AND SYMPTOMS
OF VTE?
VTE can occur without any warning, but there are several important signs and symptoms to know. Recognizing these signs and symptoms can save a life. See your doctor as soon as possible if you have any symptoms of a blood clot.
Pulmonary Embolism (PE):
Deep Vein Thrombosis (DVT):
  • Unexplained shortness of breath
  • Rapid breathing
  • Chest pain (maybe worse upon deep breath)
  • Rapid heart rate
  • Light headedness or passing out
  • Pain or tenderness, often starting in the calf
  • Swelling, including the ankle or foot
  • Redness or noticeable discoloration
  • Warmth
WHAT ARE THE RISK
FACTORS FOR VTE?
Everyone is at risk of developing VTE, however, your risk can be increased by several factors, including:
HOW IS VTE DIAGNOSED?
There are several ways that VTE can be diagnosed.
DVT
  • Duplex venous ultrasound
  • Venogram
  • Magnetic resonance imaging (MRI)
PE
  • Computed tomography angiography (CTA)
  • Blood tests
  • Ventilation-perfusion (V/Q Scan)
  • Pulmonary angiogram
WHAT ARE THE TREATMENT
OPTIONS FOR VTE?
There are different ways to treat VTE, including drugs and a minimally invasive procedure known as mechanical thrombectomy.
Anticoagulation Drugs
(Blood thinners)
The majority of VTE patients are treated with anticoagulation or blood thinners alone. Anticoagulation may reduce the formation of a new clot but cannot dissolve or break down existing clot.
Thrombolytic Drugs
(Clot-busters)
These drugs work to dissolve blood clots to restore blood flow. While clot-busters may work on newer clots, they become less effective the longer the clot has been in the body. This treatment is also linked with a higher risk of bleeding, which can be deadly and requires a stay in the intensive care unit (ICU).
Mechanical thrombectomy
(DVT & PE)
DVT: Minimally invasive, mechanical thrombectomy with the ClotTriever system physically removes the clots from the body and restores blood flow to the affected area. Many patients experience immediate symptom relief and are able to return to normal activity shortly after the procedure.

PE: Minimally invasive, mechanical thrombectomy with the FlowTriever system aspirates the clots from the pulmonary arteries and often provides patients with immediate symptom relief. Treatment of PE with the FlowTriever system does not require thrombolytics, so many patients can go home shortly after their procedure.

Indications for Use:
The FlowTriever® system is indicated for (1) the non-surgical removal of emboli and thrombi from blood vessels and (2) injection, infusion and/or aspiration of contrast media and other fluids into or from a blood vessel. The FlowTriever system is intended for use in the peripheral vasculature and for the treatment of pulmonary embolism. Triever catheters are intended for use in treating clot in transit in the right atrium but not in conjunction with FlowTriever catheters. The FlowTriever2® catheter is intended for use in the peripheral vasculature. The FlowSaver® blood return system is used with Triever catheters for autologous blood transfusion. The ClotTriever® Thrombectomy System is indicated for: (1) The non-surgical removal of thrombi and emboli from blood vessels. (2) Injection, infusion, and/or aspiration of contrast media and other fluids into or from a blood vessel. The ClotTriever Thrombectomy System is intended for use in the peripheral vasculature including deep vein thrombosis (DVT). The ClotTriever Sheaths are indicated for use as a conduit for the insertion of endovascular devices into the vasculature while minimizing blood loss associated with such insertions.
