Private DVT Ultrasound Scan in London
A swollen, painful or hot calf shouldn't be a waiting game. Doppler ultrasound of the deep veins — the definitive first-line DVT test — with the answer explained at your scan, and a same-day NHS handover if a clot is found. £179, self-referral.
Why might I need a DVT scan?
The people we see are a real mix: the classic swollen calf after a long-haul flight, post-operative patients whose leg has changed during recovery, people on long periods of immobility or with clotting risk factors — and, just as often, highly anxious individuals who have Googled their symptoms and need the question answered properly rather than left to spiral. All are legitimate reasons to scan: a deep vein thrombosis is common, treatable, and dangerous mainly when ignored. Our guides to calf swelling and leg pain after flying cover the symptom side in depth.
What does a DVT ultrasound involve?
A Doppler examination of the deep veins from groin to calf: each vein segment is visualised, gently compressed — a healthy vein squashes flat; a clotted one resists — and its flow assessed with colour and spectral Doppler. Both compression and flow tell the story, and where useful the other leg is compared. The examination takes around 30 minutes, needs no preparation, and you watch the screen throughout with everything explained as we go.
What happens if we find a clot — the same day
If a deep vein thrombosis is confirmed, the protocol is immediate: we write a fast-tracked, urgent clinical report and arrange a same-day transfer to your local NHS Ambulatory Care unit or A&E to commence anticoagulants. You leave with the report in hand, the pathway already moving, and no ambiguity about what happens next. A positive DVT scan is never an email that waits until tomorrow — it is a conversation, a phone call, and a plan, before you leave the building.
Understanding your results and next steps
Clear veins: genuine reassurance, documented — and if symptoms persist, your report notes the likelier culprits (a Baker's cyst, a muscle tear, superficial phlebitis) and the sensible next step, because ruling out the dangerous thing is only half the job. Superficial clot (phlebitis): explained honestly — usually less dangerous but sometimes needing treatment and follow-up, stated clearly for your GP. Deep vein thrombosis: the same-day pathway above. Every outcome ends with you knowing exactly where you stand — the principle behind all our follow-up care.
You have sudden breathlessness, chest pain, coughing blood, or feel faint alongside a swollen leg. These can signal a pulmonary embolism — a clot that has travelled to the lungs — and that is a 999 emergency, not an ultrasound appointment.
