No Placebo-Only Group

Summary

This trial will study how ultrasound and microbubble contrast agents can accelerate healing of severe non-healing ulcers caused by PAD. It will measure tissue perfusion changes in the affected limb & wound.

Who is the study for?
This trial is for people with severe non-healing ulcers due to Peripheral Arterial Disease (PAD), specifically those who have not seen any improvement in the past 3 months. Participants must have a confirmed PAD diagnosis and be classified as having Critical Limb Ischemia. Those with major illnesses affecting the limb, pregnant or breastfeeding women, allergies to ultrasound contrast agents or PEG, unstable blood pressure, or upcoming amputation are excluded.
What is being tested?
The study tests if using ultrasound to shake microbubble contrast agents can help heal severe ulcers caused by poor blood flow in PAD patients. It looks at whether this treatment speeds up healing and improves blood flow in the affected limb compared to usual care without these ultrasound effects.
What are the potential side effects?
Potential side effects may include discomfort from the ultrasound procedure itself and possible allergic reactions to the microbubble contrast agent used during therapy.
