Thompson Test
Procedure
The Thompson test is a physical examination maneuver used to assess for the presence of deep vein thrombosis (DVT) in the calf.
How to Perform the Thompson Test
To perform the Thompson test, the patient lies supine on the examination table with their knees extended and their feet flat on the table. The examiner then squeezes the calf of the patient's leg.
If the patient experiences pain in the calf or behind the knee, the test is considered positive and suggests the presence of a DVT.
Interpretation
A positive Thompson test is highly suggestive of DVT, but it is not diagnostic. Further testing, such as an ultrasound, may be necessary to confirm the diagnosis.
Limitations
The Thompson test is not as sensitive as other tests for DVT, such as ultrasound. It may also be difficult to perform in patients who are obese or who have other conditions that make it difficult to squeeze their calf.
Conclusion
The Thompson test is a simple and easy-to-perform test that can help to identify patients who may have DVT. However, it is important to note that the test is not diagnostic and that further testing may be necessary to confirm the diagnosis.
