Lumbar sympathectomy: a single needle technique

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.
