Transforaminal periradicular infiltration guided by CT for unilateral sciatica--an outcome study.

Area of Science:

• Neurosurgery
• Pain Management
• Radiology

Background:

• Sciatica, characterized by leg and back pain, often requires targeted treatment.
• Transforaminal periradicular infiltration is a recognized method for evaluating and treating lumbosacral pain.

Purpose of the Study:

• To evaluate the efficacy and safety of computed tomography (CT)-guided transforaminal periradicular infiltration for unilateral sciatica.
• To assess pain reduction and improvement in the straight leg-raising test (SLRT) post-procedure.

Main Methods:

• 143 patients with unilateral sciatica underwent CT-guided transforaminal periradicular infiltration using local corticosteroids and anesthetics.
• Needle placement and medication spread were visualized using computed tomography.
• Patient outcomes, including pain levels and SLRT results, were monitored post-procedure.

Main Results:

• Successful needle puncture was achieved in all 143 patients.
• 140 patients experienced recovery from leg and back pain and showed improved SLRT results.
• Only minor complications were observed; no major complications or mortality occurred.

Conclusions:

• CT-guided transforaminal periradicular infiltration is a safe and precise method for treating sciatica.
• The technique allows accurate needle positioning and visualization of medication spread in the periradicular space.
• This minimally invasive approach offers significant pain relief and functional improvement for sciatica patients.
