Overview

Supports noninvasive DVT diagnosis by ultrasonography; confirms high accuracy in this cohort but leaves open generalizability and prospective validation.

Structured PICO

Does real-time ultrasonography accurately diagnose deep venous thrombosis of the leg compared to venography in patients with suspected DVT?

P
Population
121 consecutive patients with a clinical diagnosis of deep venous thrombosis of the leg
I
Intervention
Real-time ultrasonography evaluating the common femoral vein and popliteal vein for intraluminal echoes, compressibility, and response to Valsalva maneuver
C
Comparator
Venography
O
Outcome
Diagnostic accuracy (sensitivity and specificity) of ultrasonography findings for deep venous thrombosissurrogate

Vein compressibility assessed by real-time ultrasonography is a highly accurate method for diagnosing deep venous thrombosis, achieving 96% sensitivity and 97% specificity.
