Thermovision-controlled lumbar sympathetic blockade in chronic limb-threatening ischemia treatment

Chronic limb-threatening ischemia (CLTI), the end-stage of lower extremity artery disease (LEAD), occurs with growing prevalence around the globe and is associated with increased healthcare costs. CLTI is defined by the presence of LEAD in combination with rest pain, gangrene, or lower limb ulceration lasting more than two weeks. Despite unclear results of abdominal surgical lumbar sympathectomy, novel interventional minimally invasive fluoroscopy-guided procedures seem to be promising. A prospective interventional study will be conducted, primarily targeting patients afflicted by critical limb ischemia, with the incorporation of thermal vision control and tissue oxygen monitoring.

Inclusion Criteria:

• Chronic limb-threatening ischemia-Patients with chronic leg pain for at least 6 months with intensity (VAS >=5)
• those who (only if a signature was obtainable), or whose legal guardian,fully understood the clinical trial -details and signed the informed consent form

Exclusion Criteria:

• Chronic Venous Insufficiency
• women with positive a pregnancy tests before the trial or who planned to become pregnant within the following 3 years
• other patients viewed as inappropriate by the staff
• disagreement with participation in the study
