Deep venous thrombosis: predictive value of signs and symptoms
Insights
Certain clinical factors strongly correlate with deep venous thrombosis (DVT). Identifying these risk factors aids in diagnosing and treating DVT effectively.
Area of Science:
- Medical diagnostics
- Vascular medicine
- Clinical epidemiology
Background:
- Deep venous thrombosis (DVT) is a significant clinical concern.
- Accurate diagnosis of DVT is crucial for effective patient management.
- Predictive clinical factors for DVT require further elucidation.
Purpose of the Study:
- To retrospectively evaluate the relationship between clinical findings and deep venous thrombosis (DVT).
- To identify specific signs, symptoms, and patient history elements correlated with DVT.
- To assess the utility of receiver operating characteristic (ROC) curves in DVT prediction.
Main Methods:
- Retrospective analysis of 154 patients undergoing contrast phlebography for DVT evaluation.
- Assessment of clinical history, signs, symptoms, and laboratory/radiographic results.
- Construction of receiver operating characteristic (ROC) curves to evaluate predictive value.
Main Results:
- Malignancy, recent blood transfusions, surgery, heart failure, immobility, and infection showed strong correlations with acute thrombophlebitis.
- ROC curves demonstrated the additive value of certain clinical factors in predicting DVT.
- A selectable cutoff point using ROC curves can guide diagnostic and treatment decisions.
Conclusions:
- Specific clinical factors are highly predictive of deep venous thrombosis (DVT).
- ROC curve analysis provides a quantitative method to aid in DVT diagnosis and management decisions.
- This study offers a framework for optimizing DVT evaluation pathways.
Abstract:
The clinical history, signs, symptoms, and laboratory and radiographic results of 154 consecutive patients who had contrast phlebography for evaluation of deep venous thrombosis were evaluated retrospectively to determine their relationship to deep venous thrombosis. Malignancy, history of recent blood transfusions, recent surgery, congestive heart failure, immobility, and infection exhibited the strongest correlation with acute thrombophlebitis. Receiver operating characteristic curves were constructed to demonstrate the additive value of certain signs and symptoms in predicting the development of or protection from deep venous thrombosis. With these curves, a cutoff point can be selected for this population that will aid in determining which patients should undergo further diagnosis and/or treatment in the evaluation of deep venous thrombosis.
