[Classification of post-cordotomy dysesthesia].
Postcordotomy dysesthesia was classified from the clinical features of dysesthesia following percutaneous cervical cordotomy (PCC) in 66 patients. Dysesthesia occurred in 10 (15.2%) of 66 patients and was classified into three types. In the first type, dysesthesia occurred at the region where pain had been before PCC, and pain sensitivity had been lost due to PCC. This type of dysesthesia occurred in 6 patients. In this type, the peripheral nerve damage caused by tumor invasion was presumably the cause of dysesthesia. In the second type, dysesthesia occurred all over the region where pain sensitivity had been lost due to PCC. This type of dysesthesia occurred in 2 patients. The destruction of second order neurons of the nociceptive pathway by PCC was presumably the cause of this type of dysesthesia. In the third type, dysesthesia occurred at the region where pain had been before PCC and pain sensitivity had partially recovered. This type of dysesthesia occurred in 3 patients. The reduction of the effect of PCC was presumably the cause of this type of dysesthesia.
