Percutaneous Cervical Cordotomy and Subarachnoid Phenol Block Using Fluoroscopy in Pain Control of Costopleural Syndrome

Abstract

We examined the efficacy of percutaneous cervical cordotomy (PCC) and subarachnoid phenol block using fluoroscopy (SAPB-F) for control of chest and/or back pain from costopleural syndrome. The efficacy of each block was evaluated by changes in pain score (PS), analgesic dose and performance status 1 week after the block, as well as by the complications. Between 1980 and 1986, PCC was performed in 10 patients. SAPB-F was performed in 13 patients between 1987 and 1991. Pain was not well controlled by analgesics in any of these patients. For PCC the follow-up period was 94.7 +/- 71.1 days. PS (VAS, 0-10) reduced from 8.5 +/- 0.9 to 3.0 +/- 2.7. No analgesics were needed in 4 patients. Pain recurred in 1 patient. Hemiparesis occurred in 2 patients. General fatigue occurred in 6 patients. In 4 patients with these complications performance status deteriorated and did not recover during the follow-up period. For SAPB-F the follow-up period was 71.8 +/- 44.0 days. SAPB-F was designed to achieve selective phenol deposit at the targeted nerve root. PS decreased from 7.5 +/- 1.9 to 2.7 +/- 2.6. No analgesics were needed in 5 patients. Pain recurred in 3 patients. There were no complications and no changes in performance status. From this study we concluded that PCC is an effective method of pain control for costopleural syndrome, but a risk of serious complications is involved. SAPB-F is an effective and safe method and should be the first choice of nociceptive pathway block.
