Deep Vein Thrombosis (DVT)

Those who cannot remember the past are condemned to repeat it.

- George Santayana (1863-1952)

Had to do a presentation on Deep Vein Thrombosis recently and cashed in on the opportunity to do a cybermed article at the same time.

What is Deep Vein Thrombosis?
Deep vein thrombosis is a medical condition for blood clotting. This is a process for formation of thrombi that either partially or completely block circulation in a deep vein, generally in the lower extremities. Unlike the superficial veins just below the skin surface, the deep veins are surrounded by powerful muscles that contract to force blood back to the heart. One-way valves inside the veins prevent backflow of blood between muscle contractions. The quick and efficient return of blood to the heart using the power of the leg muscles is a crucial phase of the circulatory process.

When the rhythm of circulation slows down due to illness, injury, or inactivity, there is a tendency for blood to accumulate or "pool." A static pool of blood provides an ideal environment for clot formation.

There are several sites out there some with fancy Flash media to illustrate the disease.

The Center for Outcomes Research (COR) serves as the scientific coordinating center for a growing number of national and international outcomes registries. COR’s responsibilities include maintaining patient and physician confidentiality, design of data collection instruments, data management and publication development.

COR is based at the University of Massachusetts Medical School (UMMS) in Worcester, Massachusetts, part of the 5-campus UMass System. Established in 1994, COR is an outgrowth of the Worcester Deep Vein Thrombosis Study, a five-year NIH-supported program, which demonstrated that physicians are more likely to improve their patient management practices if they are provided with valid data on their own practices and outcomes along with regional and national benchmarks.

Select VTE Education ( and you have several choices. You have the Best Practice manual which can be viewed on the web or downloaded as a pdf file for printing and viewing this concise "handbook". They have another link to additional web sites for further information.


This site offers a Flash as well as a html version. You can click on animation on how dvt occurs in the body.

Click on "DVT" and you have a choice of text and animation.



Investigators Against ThromboEmbolism (INATE) is an initiative that was started early in 2001 by a consortium of 12 prominent investigators to improve the management of patients with venous thromboembolism (VTE) worldwide. INATE is an international, multidisciplinary program dedicated to the use of clinical evidence and real-world experience to improve the management of venous thromboembolic disease. This is to be achieved by increasing the awareness of the problem, improving cross-disciplinary communication and addressing unmet medical needs among healthcare professionals and patients.

The INATE Core Group members come from a range of countries and a variety of disciplines in the field of VTE, including:

  • general surgery
  • orthopedic surgery
  • vascular medicine
  • hematology
  • oncology
  • anesthesiology
  • internal medicine
  • obstetrics and gynecology
  • pulmonology
  • critical care

Click on the "Professional" choice and you have a link to a slide set of information. However you need to register to access the information and this is free.


The free site to search for published indexed articles. If you click the link on my web page it will retrieve all articles on DVT....otherwise use the link provided above and type DVT and press on "Go".


Google site allows a search on DVT related websites on the internet. Just type DVT and do a google search. If you access this article from the web just click on the hyperlink above. Need fear just select "Images" and you have all the images you need!
