Highlights |
• | Anterolateral cordotomy is effective for intractable cancer pain alleviation. |
• | Advancing technology allows accurate and safe targeting of the spinothalamic tract. |
• | There is a need to continue to promote and teach anterolateral cordotomy. |
Abstract |
Introduction |
Anterolateral cordotomy (AL-C) is a long-established treatment for alleviating intractable cancer pain. However, AL-C has progressively fallen into desuetude, leading to the risk of a definitive loss of expertise within neurosurgical teams. Our objective was therefore to provide an update on percutaneous and open AL-C, with special emphasis on contemporary operative technique.
Material and methods |
Patient selection, indications, outcomes and up-to-date operative technique are reviewed through illustrative cases, including intraoperative photographs and video.
Results |
Main indications are represented by unilateral, nociceptive pain refractory to best pharmacological treatment in patients with limited life expectancy. Percutaneous AL-C is performed under cooperative sedation at C1-C2 level. CT myelography guidance and intraoperative electrophysiology allow accurate targeting of the spinothalamic tract (STT). Thermocoagulation is performed at 80 °C for 60 s during a Mingazzini maneuver, in order to promptly detect the potential onset of a motor weakness. Open AL-C is performed under general anesthesia at T2-T3 level. The dentate ligament is suspended to gently rotate the spinal cord and expose the anterolateral column. Section of the STT is made with a micro scalpel blade at a depth of 4−5 mm, from the dentate ligament to the emergence of ventral rootlets. Success rate after AL-C is high and allows a marked reduction in antalgic drugs intake. Main limitations include failure in achieving long-standing pain relief and the new occurrence of spontaneous, mirror pain.
Conclusion |
AL-C is a safe and effective option for the management of opioid-resistant cancer pain, which should be part of the neurosurgeon’s armamentarium.
