{{Deep vein thrombosis}}
{{Deep vein thrombosis}}
==Overview==
==Overview==
The actual physical signs of venous thrombosis can be quite unreliable. There may be pain and tenderness in the thigh along the course of the major veins
The physical examination may be completely normal in patients with DVT.  A high degree of suspicion is necessary for early identification of [[venous thrombosis]], as sometimes these patients are admitted with a different complaint and a thorough physical exam gives a clue to the diagnosis.  The typical symptoms of DVT include unilateral calf or thigh [[tenderness]], [[swelling]], and/or [[erythema]].  Since DVT can be complicated by [[pulmonary embolism]] (PE), the physical exam should include assessment of the signs of [[PE]], such as [[tachypnea]] and [[tachycardia]] among others.

== Physical Examination ==

* Temperature, [[blood pressure]], [[heart rate]] and [[respiratory rate]] may all be within normal range in [[DVT]].
* Among patients with [[DVT]] complicated by [[PE]], the following might be present:
** [[Blood pressure]] lower than baseline, suggestive of [[cardiogenic shock]] (associated with [[tachycardia]] and end organ hypoperfusion)

** [[Low grade fever]]


[[Obesity]] may be present.
=== Extremities ===
One of the most significant part of the physical exam in a patient with a suspected [[DVT]] is the measurement of the size of both legs at the same point (usually measured vertically from the knee joint), to assess for differences. If a difference is detected, and there is suspicion of DVT, further tests should be conducted. The complete exam of the extremities should include the assessment of all the following:
* Unilateral calf or thigh tenderness
* Unilateral calf or thigh [[pitting edema]]
* Unilateral calf or thigh swelling
* Difference in calf diameters > 3 cm (the calf circumference is measured 10 cm below the tibial tuberosity)
* Difference in thigh diameters (the thigh circumference is measured 10-15 cm above the patella)
* Unilateral calf or thigh warmth
* Unilateral calf or thigh [[erythema]]
* Palpable cord (a thickened palpable vein suggestive of [[vein thrombosis|thrombosed vein]])
* Dilatation of unilateral collateral [[superficial veins]]
* Localized tenderness upon palpation of the [[deep veins]]
** Posterior calf
** Popliteal fossa
** Inner anterior thigh


The patient may complain of lower limb pain.
===Skin===
* Generalized [[edema]] (suggestive of [[right heart failure]], or [[nephrotic syndrome]])
* [[Cyanosis|Cyanotic]] and cold skin, lips, nail bed (suggestive of [[cardiogenic shock]])


==Vitals==
===Abdomen===
Temperature, Blood Pressure, Pulse and Respiratory rate may all be within normal range.
* [[Ascites]] (suggestive of [[Budd Chiari syndrome]], that is [[hepatic vein thrombosis]])
==Extremities==
* [[Hepatomegaly]] (suggestive of [[Budd Chiari syndrome]], that is hepatic vein thrombosis)
Physical examination may reveal
*Palpable cord (reflecting a thrombosed vein)  
*Calf or thigh pain
*Unilateral edema or swelling with a difference in calf diameters, warmth, tenderness and erythema.
*Superficial venous dilation.


==Test==
===Heart===
*[[Homan's test]]: is said to be present when passive dorsiflexion of the ankle by the examiner elicits sharp pain in the calf.. A '''positive Homans''' sign does not positively diagnose DVT (poor positive predictive value), and a '''negative Homans''' sign does not rule out the DVT diagnosis (poor negative predictive value).
Among patients with [[DVT]] complicated by [[PE]], the following might be present:
*Pratt's sign: Squeezing of posterior calf elicits pain
* [[Cardiac murmur]]
However, these [[medical sign]]s do not perform well and are not included in [[clinical prediction rule]]s that combine best findings in order to diagnose DVT.<ref name="pmid16403932">{{cite journal| author=Wells PS, Owen C, Doucette S, Fergusson D, Tran H| title=Does this patient have deep vein thrombosis? | journal=JAMA | year= 2006 | volume= 295 | issue= 2 | pages= 199-207 | pmid=16403932 | doi=10.1001/jama.295.2.199 | pmc= | url=http://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=16403932  }}  [http://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=16813372 Review in: ACP J Club. 2006 Jul-Aug;145(1):24] [http://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=17213132 Review in: Evid Based Med. 2006 Aug;11(4):119] </ref>

Overview

The physical examination may be completely normal in patients with DVT. A high degree of suspicion is necessary for early identification of venous thrombosis, as sometimes these patients are admitted with a different complaint and a thorough physical exam gives a clue to the diagnosis. The typical symptoms of DVT include unilateral calf or thigh tenderness, swelling, and/or erythema. Since DVT can be complicated by pulmonary embolism (PE), the physical exam should include assessment of the signs of PE, such as tachypnea and tachycardia among others.
