摘要:

A series of 93 consecutive patients whose myelograms were reported as showing arachnoiditis were studied, and correlations between the radiographic appearance and the clinical and surgical findings were tabulated. All but 1 patient had had either lumbar disc surgery and/or Pantopaque myelography. The study led to a classification of such roentgenogram changes which revealed that the majority of patients studied did not have the usual adhesive arachnoiditis, but the picture they projected was more commonly due to spinal stenosis, extraarachnoid dye injection, extradural scar, etc. Only 1 patient of the 93 presented the classic severely disabling paraparesis, intractable pain, and loss of bowel and bladder functions commonly ascribed to adhesive arachnoiditis. The presence of such myelographic changes need not deter necessary surgery for co-existing disc pathology, nerve root entrapment, or spinal stenosis. In only a small percentage of these patients could the symptoms be attributed to the arachnoiditis changes seen in the myelogram

摘要:

Late sequelae (adhesive arachnoiditis) have been reported following myelography with the oily contrast medium (Pantopaque) and with the ionic water-soluble contrast media methiodal sodium (Abrodil, Conturex, Kontrast U) meglumine iothalamate (Conray Meglumine) and meglumine iocarmate (Bis-Conray, Dimer-X). Adhesive arachnoiditis has not yet been reported after the use of the nonionic watersoluble contrast medium metrizamide (Amipaque). Thus, this is considered the contrast medium of choice for lumbar myelography. Using the recommended dose of 10 ml with an iodine concentration of 170 mg/ml for this examination, adhesive arachnoiditis is unlikely to occur. Increased osmolality of spinal fluid after injection of contrast medium is related to increased frequency of arachnoiditis.

摘要:

Myelography was performed on 80 monkeys to study postmyelographic arachnoiditis. Metrizamide myelography caused arachnoiditis when high concentrations were used, but not with the usual clinical concentrations. Arachnoiditis resulted after myelography with meglumine iocarmate; however, the risk of arachnoiditis was reduced by diluting the contrast medium. Prophylactic intrathecal methylprednisolone was not effective in preventing arachnoiditis. Blood in the cerebrospinal fluid did not affect the degree of arachnoiditis.

摘要:

In lumbar myelography, early side effects occur in about half the patients examined with modern water-soluble contrast media. At myelography with Amipaque (metrizamide) these reactions are usually minor, and serious adverse reactions are rare. In our own series of 650 consecutive lumbar myelographies with Amipaque there were no serious adverse effects. Minor adverse reactions occurred in 56% of the patients. Transient electroencephalogram (EEG) changes were seen in 14% of the patients, with only 5 patients showing paroxysmal spike activity. Adhesive arachnoiditis following lumbar myelography occurs significantly less often with Amipaque than with any other contrast medium. The properties of Amipaque provide excellent possibilities for detailed studies of all parts of the spinal subarachnoid space, and the medium constitutes a new and interesting aid for these investigations.

摘要:

Arachnoiditis ossificans is uncommon and has been reported to occur in areas surrounding the brain stem, the spinal cord, and the cauda equina. Predisposing etiologic factors include vascular anomalies, spinal anesthetics, and meningitis. This report adds a case of arachnoiditis ossificans about the cauda equina occurring after septic complications following laminectomy. Surgical excision of the ossific tissue resulted in clinical improvement.

摘要:

Chronic lumbar radiculopathy following spinal surgery is reported, in which 7 of 25 patients reviewed developed a postoperative syndrome immediately after their original surgery. Later, sometimes years later, all 7 patients developed severe chronic spinal arachnoiditis. This syndrome was characterized by transient violent spasms in the legs, muscle cramps, increased radicular pain, and often fever and chills. The recognition of this syndrome and a proposed method of treatment is discussed.
