Duplex scanning in the assessment of deep venous incompetence

J Vasc Surg. 1986 Sep;4(3):237-42.


A noninvasive method to evaluate deep venous incompetence by duplex scanning is presented. For this test, it was decided to have the patient standing so as to make the test less dependent on the need for patient cooperation and to allow gravity to produce reflux. Results were validated against ambulatory venous pressure measurements. The method described had a sensitivity of 84% and specificity of 88%. Duplex scanning is a useful screening test for detecting the presence and site of incompetence in patients with deep venous disease.
