Why the study?
Does clinical evaluation or ultrasound accurately diagnose deep vein thrombosis compared to ascending phlebography?
Does clinical evaluation or ultrasound accurately diagnose deep vein thrombosis compared to ascending phlebography?
Clinical evaluation and ultrasound have moderate sensitivity and specificity for DVT, but ascending phlebography remains necessary for certain diagnosis of major central thrombosis.
Moderate accuracy of clinical exam and ultrasound for DVT cautions against sole reliance; leaves open optimal noninvasive strategies versus phlebography.
The diagnostic precision of clinical evaluation and of ultrasound examination in the diagnosis of deep vein thrombosis was obtained by ascending phlebography. The diagnostic specificity and diagnostic sensitivity of clinical examination was 0.72 and 0.78 and with ultrasound 0.73 and 0.70. With no other examination than phlebography is it possible to demonstrate major central thrombosis in the leg with certainty.
