Bleeding from cerebral arteriovenous malformations as part of their natural history.

The case records of 191 patients with a cerebral arteriovenous malformation (AVM) were reviewed to determine bleeding characteristics of these lesions. Possible influences of age, sex, the location and size of the AVM, type of initial hemorrhage, and condition of the patients were analyzed. Of these 191 patients, 102 had a single hemorrhage, 32 had a recurrent hemorrhage, and 57 never bled. The follow-up period for patients with an unruptured AVM was a mean of 4.8 years and a maximum of 31 years; for those with a ruptured AVM, the mean was 2 years, and the maximum 37 years. Size of the AVM was significantly related to the risk of first hemorrhage. The average yearly risk for first hemorrhage was between 2% and 3%. Bleeding occurred most frequently in the 11- to 35-year-old age group. The risk of rebleeding increased with advancing age. Among 93 patients followed after their AVM had ruptured, the risk of rebleeding was 6% in 1 year. After the first year, the average rebleeding rate was about 2% per year up to 20 years.

Arachnoid cysts in children.

Twenty-seven cases of intracranial arachnoid cysts in children aged 1 to 16 years have been studied with attention to diagnosis, pathologic findings, and surgical treatment. In nine patients, the cyst was located in the posterior fossa. In eight patients, there were other CNS or other organ system abnormalities. No specific symptom complex can be ascribed to arachnoid cysts in that the clinical manifestations are the result of their size and location, secondary complications, and remote effects. This is illustrated in the ten cases reported.

Spinal cord abscess: a review.

The literature on abscesses in the spinal cord has been reviewed. A total of 54 cases was reported. A digest is made of information on the subject including the diagnosis, pathology, treatment and the results to be expected. The best results have been achieved by operation plus antibiotic therapy. It is essential that the abscess be drained after aspiration. A case of ours showing the salient features and management of a subacute cervical spinal cord abscess is also reported.

Hypothalamic tumors in children. Their diagnosis and management.

17 intrinsic hypothalamic tumors in infancy and childhood occurring between 1963 and 1973 were analyzed in detail because of the consistent mode of approach to diagnosis, therapy and follow-up care. Careful examination of the symptom-time sequence and location provided anatomical-clinical correlations and was even suggestive of the probable histologic type of lesion present. The postoperative and long-term management problems have led to significant conclusions. The best results were obtained with those patients who underwent craniotomy and biopsy, followed by irradiation therapy.
