Summary

In endoscopic spinal nerve root decompression surgery, the intraoperative nerve exploration is time-consuming and critical. According to statistics, the incidence of nerve root injury under spinal endoscope is 1.8-2.5%. Damage to nerve roots may lead to postoperative sensory retardation and motor weakness, thereby impairing the physical function of patients. A real-time auxiliary intraoperative nerve identification technology is necessary.

In this prospective, open-label, randomized, parallel controlled trial, 40 patients who undergo endoscopic spinal surgery are included. Subjects are randomly divided into control group and low, medium and high Indocyanine green(ICG) preoperative administration experimental group. Standard endoscopic spinal surgery is performed in the control group. Patients in the experimental group received an intravenous injection of ICG before surgery, and a standard endoscopic spinal surgery is performed with the use of a fluoroscopic endoscopic surgical imaging system to assist the surgeon in identifying and protecting the nerve roots.

The main objectives of this experiment are (i) to explore the safety and feasibility of ICG fluorescence imaging to assist in nerve root identification during endoscopic spinal surgery and (ii) the effectiveness of this technique for endoscopic search for nerve roots. The secondary objective is to explore the optimal ICG dosing regimen.
