Mr X, 69 years old, has been suffering from hyperalgesic sciatica for 6 months.
The various examinations carried out are not conclusive: the MRI does not find any clear signs of compression at the level of the lumbar canal.
This sciatica, despite the morphine treatment, prevents M X from sleeping for more than an hour at a stretch.
The examination finds hypoesthesia (decreased sensitivity) or even anesthesia (absence of sensitivity) in the sciatic area (red zone).
However, this described deficit only affects the lower part of the leg and rises upwards when the pain intensity increases. The interrogation of M X finds a history of laser surgery of varicose veins three months previously. Careful examination of Mr X found a small depigmented area on the outer upper part of his leg (green area). Examination of this area resulted in electric shocks.
The test treatment of this area leads to a complete disappearance of the pain and a return of the sensitivity of the leg. During infiltration, the existence of a zone of fibrosis 1.5 cm deep under the depigmented zone is noted.
Responsibility for the fibrosis of the vein that was burned by the laser is very likely.
