BackgroundAdhesive lumbar arachnoiditis is essentially an unknown, unreported, and unrecognised disease. It was better known at a time when oil-based dye was used for myelography. The factors causing this pathogenesis remain unknown. In addition, diagnosis is hard to achieve and frequently attained only by an exclusion process. Only in severe cases, using high-resolution MRI, is evidence for the diagnosis obtainable.Method/PatientsModern neuroendoscopic techniques allow diagnosis at a reasonable risk (comparable with lumbar tap) and enable us substantially to treat the pain. Taken together, this means a radical new method of treatment for adhesive arachnoiditis. The treatment of a 23-patient research group suffering from adhesive lumbar arachnoiditis is monitored and described.ResultsVarious endoscopic manoeuvres were carried out. Endoscopic reduction of adhesions and internal shunting for CSF flow between subarachnoidal and epidural space improved both the biomechanical abilities of rootlets and restoration of blocked CSF pathways. Its main result is the significant reduction of long-term pain registered by a visual analogue pain scale. No bad side effect other than temporary headache was found. No CSF leak syndrome was observed.DiscussionThe success of the method was directly influenced by the interventional procedure on the disturbed CSF circulation and its partial restoration (subarachnoepidurostomy). In cases of severe lumbar adhesive arachnoiditis, it was found very beneficial to implant special gravity-controlled valve systems for subarachnoid-peritoneal shunts.ConclusionAdhesive lumbar arachnoiditis is no longer a devastating diagnosis. Due to a novel endoscopic treatment of the local CSF disturbances that restores physiologic pathways, the chance exists for long-lasting improvement of the clinical condition.
