Recurrence of pituitary adenomas after transcranial operation.

A series of 289 pituitary adenomas operated upon transcranially have been assessed for the frequency of recurrence. Ten patients died in the postoperative period, and nine patients have been lost to follow up. Follow up data is therefore available in a series of 270 cases for a period extending up to 30 years after the initial operation.

Syringomyelia and its surgical treatment--an analysis of 75 patients.

A consecutive series of 75 patients with syringomyelia is presented, all of whom were treated by cranio-vertebral operations. Attention is drawn to the difficulty in assessing the results of treatment but 56 stabilised or showed modest improvement after surgery. Occluding the central canal appeared to have no greater influence on the progression of the disease than did simple decompression and did have a higher incidence of complications.

Clinical features, investigation and treatment of post-traumatic syringomyelia.

Thirteen patients who sustained spinal cord trauma causing persisting disability, developed new symptoms, the chief one of which was severe pain unrelieved by analgesics. The clinical diagnosis of post traumatic syringomyelia was confirmed in each case by means of myelography, as well as endomyelography in seven patients. In every case exploration of the spinal cord syrinx was performed.

Angiomas of the spinal cord: review of the pathogenesis, clinical features, and results of surgery.

Twenty-four patients with angiomas of the thoraco-lumbo-sacral region of the spinal cord, which characteristically occur in elderly men and are situated on the dorsum of the cord, were subjected to surgery after diagnosis by selective arteriography. It is suggested that in this variety of angioma the operation produced its effect by eliminating the raised pressure in the venous and capillary vessels within the spinal cord. There was no evidence of an arterial "steal.
