Percutaneous insertion of the spinal end of a cysto-peritoneal shunt as definitive treatment to relieve cord compression from a spinal arachnoid cyst

A case of myelopathy with both intradural and extradural spinal arachnoid cysts is reported treated by cysto-peritoneal shunt, the spinal end of which was inserted percutaneously under fluoroscopic control. The site of drainage was determined by findings at computed myelography. The case illustrates the value of the latter in demonstrating the pathological bio-mechanics producing myelopathy in this condition. (orig.)
