Promising Leg-Saving balloon study halted early
NCT ID NCT05755412
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested a special balloon that uses sound waves (shockwaves) to crack open hard calcium blockages in the leg arteries of people with critical limb ischemia, a condition where poor blood flow can lead to pain, wounds, or even amputation. The goal was to see if the balloon was safe and effective at restoring blood flow and preventing the need for repeat procedures. However, the study was stopped early and only enrolled 9 people, so the results are very limited.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Age ≥18 years * Patient has signed an approved informed consent form * Patient with Critical Limb Ischaemia, Rutherford category 4 (ischaemic rest pain), 5(minor tissue loss) or 6 (major tissue loss) * Patient with Stenotic (\>50% luminal loss) or occluded infrapopliteal artery, including the tibiofibular trunk, the anterior tibial artery, the posterior tibial artery and the peroneal artery * The vascular lesion length will be no longer than 150 mm. * Patient with no significant disease at the inflow: common iliac, external iliac, superficial femoral and popliteal artery on the ipsilateral side prior to enrollment, and patient with no significant disease at the outflow - runoff to ankle level: plantar for posterior tibial, pedal for anterior tibial, anterior and posterior perforant branches for peroneal vessels or previous successful revascularization of the disease segments (inflow-outflow) * Live expectancy \> 1 year. * Presence at least ≥1 filling pedal vessel on the target limb. Exclusion Criteria: * Subject pregnant or planning to become pregnant during the study * Subject no able to perform the follow up or other factors making clinical follow-up difficult * Acute or Subacute limb ischaemia which requires thrombolysis as first treatment modality or previous thrombolytic therapy in the last 48-72 hours. * Known allergy to concomitant medication, antiplatelet anti-coagulant or thrombolytic medication * Poor inflow due to ipsilateral stenoses or occlusions of the iliac or femoropopliteal arteries * Significant stenoses (\> 50%) distal to the target lesion that might require revascularization or impede run-off * Desert foot condition. No Patent foot main arteries * Subject enrolled in another investigational study that has not reached its primary endpoint
