Ultrasound watch could save legs after artery surgery
NCT ID NCT06702306
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether adding regular ultrasound scans to standard check-ups helps people who had keyhole surgery for blocked leg arteries. About 70 adults with chronic limb threatening ischaemia will be split into two groups: one gets usual clinic visits, the other gets extra ultrasound scans at 1, 6, and 12 months. The goal is to see if the scans are practical and if they lead to earlier treatment for new blockages.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Adults (18y+) who have had successful lower limb endovascular therapy (angioplasty, stenting, atherectomy, lithotripsy, drug eluting balloon or stent, or combination of above) for chronic limb threatening ischaemia (ischaemic rest pain, ulceration or gangrene with arterial imaging confirming peripheral arterial disease). Technical success is defined as \<30% residual stenosis in the treated segments and patient leaving hospital without a major (above ankle) amputation on study leg * Procedures within the last 3 weeks * Interventions to iliac, femoral, tibial, and pedal vessels alone or in combination * Endarterectomy or cutdown is permissible * Able to give informed consent Exclusion Criteria: * Surgical bypass or endarterectomy alone undertaken * Patient unfit for or does not want any future revascularisation * Need for major amputation due to gas gangrene, severe Charcot deformity, extensive tissue loss with unstable foot, severe pedal disease on angiography or patient request * Patient unwilling or cannot attend further surveillance * Interventions for claudication or acute limb ischaemia or trauma * Patients unable to take any form of antiplatelet therapy (aspirin or clopidogrel) * Prior leg endovascular therapy at same anatomical location in study leg (within 1 year) * Currently taking part in research that may impact on the results, design, or scientific value of this study or other studies that the potential participant may be taking part in.
