History
The first documented DVT is thought to have occurred in the 13th century, in the leg of a 20-year-old male. At some point, the increased incidence of DVT in women after childbirth was noticed, and in the late 1700s, a public health recommendation was issued to encourage women to breast feed as a means to prevent this phenomenon; the DVT was called "milk leg", as it was thought to result from milk building up in the leg.
In 1856, German physician and pathologist Rudolf Virchow published what is referred to as Virchow's triad, the three major causes of thrombosis. The triad provides the theoretical framework for the current explanation of venous thrombosis formation, although it was focused on the effect of a foreign body in the venous system and the conditions required for clot propagation.
Multiple pharmacological therapies for DVT were introduced in the 20th century: oral anticoagulants in the 1940s, subcutaneous LDUH in 1962, and subcutaneous LMWH in 1982. Diagnoses were commonly performed by impedance plethysmography in the 1970s and 1980s, but the use of Doppler ultrasound techniques, with their increased sensitivity and specificity, largely superseded this method.

Famous quotes containing the word history:
“Anyone who is practically acquainted with scientific work is aware that those who refuse to go beyond fact rarely get as far as fact; and anyone who has studied the history of science knows that almost every great step therein has been made by the anticipation of Nature.”
—Thomas Henry Huxley (182595)
“Systematic philosophical and practical anti-intellectualism such as we are witnessing appears to be something truly novel in the history of human culture.”
—Johan Huizinga (18721945)
“To summarize the contentions of this paper then. Firstly, the phrase the meaning of a word is a spurious phrase. Secondly and consequently, a re-examination is needed of phrases like the two which I discuss, being a part of the meaning of and having the same meaning. On these matters, dogmatists require prodding: although history indeed suggests that it may sometimes be better to let sleeping dogmatists lie.”
—J.L. (John Langshaw)
