This report concerns the outcome of 36 operations for spinal adhesive arachnoiditis (SAA) performed at Kyoto University Hospital since 1956; the follow-up period ranged from 1 to 25 years (average, 4 years 8 months). The original procedure involved intradural neurolysis after extradural decompression, but more recently microlysis was performed. The percentage of cases in which good results were obtained by nonmicroscopic lysis and microlysis was only 54.8%, however, when microlysis was followed by spondylodesis, the ratio increased to 80%, clearly showing the benefits of this new procedure. The authors therefore emphasize the value of spondylodesis following microlysis for symptomatic SAA.

UI	MeSH Term	Description	Entries
D007796	Laminectomy	A surgical procedure that entails removing all (laminectomy) or part (laminotomy) of selected vertebral lamina to relieve pressure on the SPINAL CORD and/or SPINAL NERVE ROOTS. Vertebral lamina is the thin flattened posterior wall of vertebral arch that forms the vertebral foramen through which pass the spinal cord and nerve roots.	Laminotomy,Laminectomies,Laminotomies

D000328	Adult	A person having attained full growth or maturity. Adults are of 19 through 44 years of age. For a person between 19 and 24 years of age, YOUNG ADULT is available.	Adults
D001100	Arachnoiditis	Acute or chronic inflammation of the arachnoid membrane of the meninges most often involving the spinal cord or base of the brain. This term generally refers to a persistent inflammatory process characterized by thickening of the ARACHNOID membrane and dural adhesions. Associated conditions include prior surgery, infections, trauma, SUBARACHNOID HEMORRHAGE, and chemical irritation. Clinical features vary with the site of inflammation, but include cranial neuropathies, radiculopathies, and myelopathies.

D013118	Spinal Cord Diseases	Pathologic conditions which feature SPINAL CORD damage or dysfunction, including disorders involving the meninges and perimeningeal spaces surrounding the spinal cord. Traumatic injuries, vascular diseases, infections, and inflammatory/autoimmune processes may affect the spinal cord.

D013123	Spinal Fusion	Operative immobilization or ankylosis of two or more vertebrae by fusion of the vertebral bodies with a short bone graft or often with diskectomy or laminectomy.
