My wife just got off a long flight and her calf is super swollen with bulging blue veins. She says it aches intensely. Her primary doctor can not fit her in today. What can we do right now? — Page 6

Diagnostic tests, such as an ultrasound, are commonly used to visualize the blood flow in the veins and confirm the presence of a clot. Blood tests may also be conducted to measure D-dimer levels, a substance released when a blood clot breaks up, which can support the diagnosis.

8. The Role of Ultrasound, Blood Tests, and Imaging in Diagnosis

Ultrasound imaging is the primary diagnostic tool for identifying DVT in the leg. It uses sound waves to create images of the blood flow in the veins and can detect blockages caused by clots.

Blood tests, particularly those measuring D-dimer levels, can indicate the presence of an abnormal blood clotting process. In some cases, additional imaging tests such as CT or MRI scans may be utilized for further evaluation, especially if there’s concern for a pulmonary embolism.

9. Treatment Options If It Is a Blood Clot—and Why Speed Matters

If a blood clot is confirmed, treatment typically involves anticoagulant medications, which help prevent the clot from growing and reduce the risk of new clots forming. In some cases, clot-dissolving medications or mechanical interventions might be necessary.
