Lower Limb DVT

Written referral by GP or Consultants

Patient Identification

The examining radiologist must check the identity of the patient immediately prior to the scan.

Venous ultrasound is the standard imaging test for patients suspected of having acute deep venous thrombosis (DVT). The scan will enable the radiologist to scan and assess the deep veins of the leg to see whether there is a clot or not.

No preparation is needed.

Clean tidy room, ultrasound gel and gloves.

Patient lying supine on couch. Common location for DVT is behind the knee, but a clot can form in any of the deep blood vessels. Ultrasound gel will be rubbed across a wide area of your leg. The gel is safe and painless. It forms a bond between the skin and the probe, making it easier for the sound waves to reach the blood vessels under the skin.

The patient is covered with couch roll, ultrasound gel is placed on patients affected limb such that the entire limb can be scanned. Patient is told that he may hear some noise and that pressure may also be applied to leg to compress the veins. The scan takes about 15-20 minutes. The probe is cleaned and disinfected after the scan and before reuse.

The patient is told the scan is finished and given tissues to clean themselves and then helped down from the table. No other special aftercare is needed.

Scan findings are communicated with the patient and the report will be faxed to the GP the next working day.
