Effect of Lumbar Sympathetic Ganglion Neurolysis in Complex Regional Pain Syndrome Patients: Permanent or Temporary
분당 서울대학교 의과대학 마취통증의학 교실
Background:
Lumbar sympathetic ganglion neurolysis (LSGN)has been known to have a longer effect period than lumbar sympathetic ganglion block (LSGB)), but no previous studies have reported on the actual effect period of LSGN. The aims of this study were to analyze the change in IRT(infrared thermographic imaging) over time in patients with complex regional pain syndrome (CRPS) who performed LSGN.
Methods:
We performed 2 times of diagnostic LSGB and decided to perform LSGN if the patient had a transient decrease in VAS score of more than 50% compared to baseline. IRTs of pre-LSGN (Tpre), post-LSGN (Tpost), 2 weeks (T2w), 1 (T1m) and 3 months (T3m) following procedure were analyzed by independent physician. The change of temperature in 2 regions; maximal pain site and plantar surface, with time were checked. The net changes in 2 regions were calculated (Tpost -Tpre = ΔT1, T2w -Tpost = ΔT2, T1m- T2w = ΔT3, T3m- T1m = ΔT4)
Results:
Twenty-five patients with type 1 or 2 of CRPS were enrolled and twenty patients were included in the final analysis. Data from 25 patients were analyzed (Table 1). The change of temperature in maximal pain site and plantar region of patients were showed in Fig. 1. Also, the mean net changes of 2 regions (maximal pain site and plantar region) between pre-LSGN and 3 months following procedure were presented in Fig. 2 We observed a significant increase of temperature at all time points compared to before LSGN. However, the elevated temperature was not maintained at three months as immediately after LSGN
Conclusions:
The temperature of maximal pain site and plantar surface in all patients increased after LSGN.
