Venous Doppler

This type of ultrasound detects

  • Superficial varicose veins
  • Clots in the deep veins
  • Blockages in the deep veins

Before the test:

Generally, you won’t need to follow any special instructions before your appointment to have a venous doppler test. You may want to wear loose, comfortable clothing that allows the technician performing the test can easily place a blood pressure cuff on your ankle and upper arm.

During the Test:

  1. The technician will put some gel onto the inside of one of your thighs to help the ultrasounds sensor slide around easily, the technician will place the sensor against your skin.
  2. Once the sensor is in place, an image appears on a video screen and the technician will move the sensor up and down along your leg—from the groin to the calf—to view the veins from different angles.
  3. The technician will press the sensor into your skin firmly every few inches to see if the veins change shape under pressure.
  4. These steps will be repeated on your other leg.
  5. As the machine measures the blood flowing through a vein, it makes a swishing noise in time with the rhythm of your heartbeat.

After the Test:

Venous testing should take 15-30 minutes, and there are no special precautions you’ll need to take following the test.

Risk to Patients:


Some patients may feel discomfort during the test.
