|May 1, 1984
Summary
Real-time B-mode ultrasound accurately detects deep venous thrombosis in extremities. This noninvasive technique offers high sensitivity and specificity, complementing existing screening methods for vascular evaluation.
Area of Science:
- Vascular Ultrasound
- Diagnostic Imaging
- Medical Technology
Background:
- Real-time B-mode ultrasound uniquely provides direct anatomic visualization of vessels.
- While established for carotid arteries, its utility for deep venous evaluation is less explored.
Purpose of the Study:
- To assess the applicability and accuracy of high-resolution real-time B-mode ultrasound for deep venous evaluation.
- To present the technique and interpretive criteria for venous ultrasound.
Main Methods:
- High-resolution real-time B-mode ultrasound was used to examine 108 upper and 215 lower extremities over 12 months.
- Thirty of these extremities underwent confirmatory venography for validation.
Main Results:
- Ultrasound demonstrated 94% specificity and 100% sensitivity for detecting deep venous thrombosis compared to venography.
- The technique accurately predicted the age of detected thrombi in 93% of cases.
Conclusions:
- Real-time B-mode venous ultrasound is a highly accurate and clinically useful noninvasive method for deep venous thrombosis detection.
- This technique complements established physiologic screening tests for vascular assessment.
