Patients who develop deep vein thrombosis (DVT) commonly have thromboembolic risk factors, such as cancer, trauma, major surgery, hospitalisation, immobilisation, pregnancy, or oral contraceptive use. However, many patients have no history of a provocation, and these patients are classified as having unprovoked or idiopathic DVT. In patients in the second group, a di­agnosis of venous thrombosis can be excluded by, careful history and examination, either because the clinical features clearly indicate the presence of another disorder (for ex­ample, arthritis, nerve compression, cellulitis) or the fea­tures are totally inconsistent with a diagnosis of deep vein thrombosis. ...

Studies have shown that symptoms and clinical signs in themselves are inaccurate for the diagnosis of DVT. Cancer (known or undiagnosed). Our strategy reduced the need for serial ultrasound testing and reduced the rate of false-negative or false-positive ultrasound studies. Lancet. J Vasc Interv Radiol. From experience, we hypothesised that this widely held view might be incorrect. The prevalence appears to be increasing, particularly because of an increased use of indwelling central venous catheters. The body has normal processes that balance between clotformation and clot breakdown. • Usually in the legs; partially or completely obstructs blood flow. 10. DVT has an annual incidence of about 1–2 per 1000 people. 8 (1) pp. 1997 Dec 20-27;350(9094):1795-8. • The most serious complication is pulmonary embolism.

Patients with symptomatic DVT can present with pain, swelling, tenderness along the distribution of the deep leg veins, erythema, or cyanosis. The clinical importance of DVT is influenced by unique factors such as cardiopulmonary reserve among mechanically ventilated patients.
