About This Presentation

Description : Check out this medical PowerPoint presentation titled "Deep Vein Thrombosis”.

This medical PowerPoint presentation is about deep vein thrombosis (DVT), a medical condition in which a blood clot forms in a deep vein, typically in the leg. It can also occur in other parts of the body, such as the pelvis or arm. DVT is a serious condition because the blood clot can break loose and travel to the lungs, causing a life-threatening condition called a pulmonary embolism (PE).

Approximately 900,000 new cases are diagnosed in the U.S. each year Reviewed 6/2019 Thrombus formation in Deep Veins of legs or thighs Deep Vein Thrombosis Tibial veins, soleal/gastrocnemius veins, popliteal vein femoral vein, deep femoral vein, common femoral vein, iliac veins.

Approximately one-third develop pulmonary embolism Deep Vein Thrombosis 15% Death

VTE: Epidemiology Untreated Proximal DVT 30-50% risk PE 12-15% mortality Treated DVT <8% risk PE Mortality <2%

VTE: Epidemiology Incidence - USA/Europe DVT: 160 per 100,000 Symptomatic non-fatal PE: 20 per 100,000 Fatal PE: 50 per 100,000

The Superficial Femoral Vein A Potentially Lethal Misnomer Warner P. Bundens, MD; John J. Bergan, MD; Nicholas A. Halasz, MD; Jay Murray, MD; Margaret Drehobl, MD. JAMA. 1995;274:1296-1298 A total of 46 family practitioners and general internists, 95 anatomists, and 85 laboratory directors. Only 24% (11/46) of the respondents would have administered anticoagulants to the patient as described
Slide 12-

Only 3% (3/95) of anatomists felt the term "superficial femoral vein" was correct, 22% (21/95) felt it was an acceptable alternative, and only 7% (7/95) of anatomists felt the term was preferred for everyday use The term "superficial femoral vein" is used by 93% (79/85) of vascular laboratories in lower limb venous duplex reports.

Correct nomenclature The term “superficial femoral vein “ should never be used, because the femoral vein is in fact a deep vein and is not part of the superficial venous system. Confusion arising from use of the inappropriate name has been responsible for many cases of clinical mismanagement and death Management of “superficial femoral vein” thrombosis should be the same as any DVT
Slide 15-

Most hospitalized patients are Moderate to High Risk for VTE Prophylaxis decreases incidence of VTE Requirement CMS/UHC/JC/NSQIP Systematic risk assessment and prophylaxis programs improve prophylaxis rates Prophylaxis included Pharmacological and Mechanical options VTE Prevention

Consider DUS screening to R/O DVT present on admission for patients with a High VTE Risk and: Transfer from another institution Down for prolonged amount of time Prolonged immobilization for extrication Consider vascular consult for acute Iliofemoral DVT with significant swelling/pain Screening/Acute proximal DVT

Are 100% of your patients receiving adequate VTE prophylaxis 100% of the time? SCD’s are a method of DVT prevention that improves the blood flow in the legs. The action of SCD’s imitates walking in order to help prevent blood clots. SCD’s should be worn while in bed and sitting in the chair, but removed for walking. The mechanical action of SCD’s affects all 3 aspects of Virchow's triad: Increases velocity of venous return, creating turbulence to prevent blood Stasis/Clotting Decreases hypercoagulability by increasing fibrinolytic activity through stimulation caused by the intermittent pneumatic compression Inhibition of vasodilation may reduce endothelial damage Benefit of compression therapy (SCD) FLOW BLOOD VESSEL
