    A novel single-needle lumbar sympathectomy technique effectively treats ischemic foot pain. This minimally invasive procedure, guided by X-ray, improves blood flow and temperature, offering significant relief to patients.

    Area of Science:

    • Vascular Surgery
    • Interventional Radiology
    • Pain Management

    Background:

    • Ischemic foot pain significantly impacts patient quality of life.
    • Lumbar sympathectomy is a treatment option for peripheral artery disease.
    • Minimally invasive techniques are sought to improve procedural safety and efficacy.

    Purpose of the Study:

    • To describe and evaluate a single-needle lumbar sympathectomy technique.
    • To assess the safety and efficacy of this technique in patients with ischemic foot pain.
    • To compare the outcomes of single-needle versus two-needle sympathectomy.

    Main Methods:

    • A single-needle lumbar sympathectomy technique utilizing the 12th rib tip as a landmark.
    • Radiological screening for precise needle placement at the L3 vertebral body.

  • Visualization of radio-opaque phenol spread in the prevertebral plane.
  • Assessment of fore-foot temperature, lower leg blood flow, ankle pressure index, and venous oxygen tension.
  • Clinical follow-up for ischemic foot pain resolution.

    • Main Results:

    • Fore-foot temperatures increased by a mean of 3°C.
    • Lower leg blood flow doubled post-procedure.
    • Significant increases observed in ankle pressure index and foot venous oxygen tensions.
    • 70% of patients experienced resolution of ischemic foot pain at 1-month follow-up.
    • Outcomes were comparable to those achieved with a two-needle technique.

    Conclusions:

    • Single-needle lumbar sympathectomy under X-ray control is an effective neurolytic sympathectomy technique.
    • This approach offers comparable efficacy to traditional two-needle methods.
    • The technique provides significant physiological improvements and pain relief for ischemic foot conditions.
