Provided By

Direct access vascular studies service for ambulatory patients with suspected acute deep vein thrombosis (DVT) at Royal Free London (RFL).

If the patient is found to have an acute DVT, they will be sent to A&E or haematology for a same-day follow-up.

The results are emailed to the practice by the secure email address supplied on the request form. Should the patient not be found to have acute DVT, the GP retains responsibility for follow-up. 

Eligibility Criteria

Inclusions

Exclusions
