[Radiofrequency-thermocoagulation in the treatment of trigeminal neuralgia: analysis of 100 cases].

A series of 100 patients suffering from trigeminal neuralgia treated by percutaneous radiofrequency thermocoagulation of the trigeminal ganglion is reported. The authors make some considerations about the basic principles of the thermocoagulation and comment a few important methods of treatment used prior to this new technique. The whole sequency of the surgical procedure is described and its results analysed. The final conclusion is that percutaneous radiofrequency thermocoagulation has become the treatment of choice for trigeminal neuralgia when the clinical treatment is not anymore effective or the side-effects of the drugs contraindicate its use.

An unusual case of multiple intracranial aneurysms.

A 49-year-old female patient with six intracranial aneurysms, all of which were treated successfully by direct surgery, is reported. She had a major subarachnoid haemorrhage 10 years ago. Because of difficulty in identifying the offending aneurysm she was not surgically treated at that time. The natural progression of intracranial aneurysms, the problem of identifying the lesion in a patient with multiple aneurysms, and an example of excellent recovery of visual function following surgical treatment are discussed.

Spontaneous spinal subdural haematoma during general anaesthesia.

Spontaneous spinal subdural haematoma causing acute spinal cord compression is a well recognized condition and often responds well to early surgical intervention. In the elderly, the haematoma usually occurs as a result of minor trauma or atherosclerosis with hypertension. We present in this report the history of a patient who became paraplegic during a general anaesthetic for an operation for removal of a ureteral calculus. Rupture of a spinal vascular malformation was found to be responsible for the subdural haematoma, which remained undiagnosed until surgical exploration.

Abscesses of the frontal lobe of the brain secondary to covert dental sepsis.

The bacterial species found in pus aspirated from brain abscesses in two patients were typical of those found in dental sepsis. Subsequently apical-root abscesses were demonstrated in the upper jaws of both patients. This evidence strongly suggests that these cerebral abscesses were secondary to dental sepsis which could have spread from the teeth to the frontal lobes by several possible antaomical pathways.

Scope of surgery for intracranial aneurysm in the elderly: a preliminary report.

Thirty-two elderly patients were reviewed six months to six years after intracranial surgery for subarachnoid haemorrhage. Out of 24 patients whose surgical outcome had been satisfactory, one had died from an unrelated illness and the remainder were well and leading normal lives. Eight patients had a poor outcome, which in some cases was due to factors other than age. In only three could a poor outcome be attributed to early surgery and advanced age. The results confirm that in at least three-quarters of patients aged 60-65 the risk of further haemorrhage can be removed by surgery without causing a major neurological deficit.

Unruptured intracranial aneurysms--an unusual source of epilepsy.

Six patients with epilepsy were found to have intracranial aneurysms, mainly in the middle cerebral territory. The mechanism of production of these presenting symptoms is considered to be a minor haemorrhage with localized destruction of brain, or calcification in the aneurysmal wall behaving as a hamartoma. In the differential diagnosis of factors causing epileptic attacks, an intracranial aneurysm should be considered, and its presence should be excluded by angiography before any blind surgical procedure for epilepsy is undertaken.

Radiofrequency thermocoagulation of Gasserian ganglion and its rootlets for trigeminal neuralgia.

Thirty-nine patients with trigeminal neuralgia, not controlled by medical treatment, were treated by radio-frequency thermocoagulation of the Gasserian ganglion and its posterior rootlets. Thirty-six received satisfactory pain relief. In 30 patients touch sensation in the treated territory was preserved. The corneal reflex was affected in only six patients, two of whom subsequently developed keratitis. There were no other complications apart from a minor unpleasant sensation in eight patients. By selectively destroying pain fibres this technique offers the scope of preserving touch sensation in the treated area. Moreover, the zone of analgesia can be restricted to the affected region by sensory mapping through electrode stimulation before thermocoagulation. Its simplicity, low morbidity, associated short hospital stay, and the increased ability to preserve touch sensation, especially of the cornea, seem to make it preferable to other forms of surgical management for trigeminal neuralgia.

An unusual case of chromophobe adenoma with conspicuous calcifications.

Abnormal calcification on skull films in the region of the sella turcica is not commonly found with chromophobe adenoma. A patient with such calcification in a verified chromophobe adenoma is presented. From the literature the incidence of calcification in these tumours is reviewed. The importance of considering a chromophobe adenoma in the differential diagnosis of parasellar calcification from the surgical point of view is mentioned.

Carotid-ophthalmic aneurysms.

Thirty-two cases of carotid-ophthalmic aneurysms are reviewed. As with intracranial aneurysms in other positions they present mainly with subarachnoid haemorrhage but, in spite of their close proximity to the optic nerve, visual involvement is infrequent. They are more common in women, more frequent on the left side, and more prone to multiplicity. In cases of multiple aneurysms a carotid-ophthalmic aneurysm is usually an incidental finding. Detailed angiographic studies employing various projections are required before treatment can be planned. Yet angiography does not always disclose some of the technical difficulties that may be encountered during surgery. Different methods of treating these aneurysms are discussed and suggestions for safe direct surgery made.

Use of epsilon aminocaproic acid (EACA) in the preoperative management of ruptured intracranial aneurysms.

The authors report their experience with the use of epsilon aminocaproic acid (EACA) in the preoperative management of a series of patients with ruptured intracranial aneurysms. A similar series of patients was taken as control. They found that EACA is of definite value in preventing recurrent hemorrhage in the preoperative period. The significance of antifibrinolytic therapy in ruptured intracranial aneurysms is discussed.

Cervical spinal interbody fusion with Kiel bone.

Experience with the use of the Kiel bone graft in anterior cervical interbody fusion in cervical spondylosis is reported. The survey reviews the results of operations on 73 disc spaces in 65 consecutive patients, from 2 to 5 years after the operation. We have failed to confirm that any bony fusion in the true sense occurs with Kiel bone in anterior cervical interbody fusion. However, the aims of the operations are achieved, namely removal of the disc and osteophyte, fixation of the spine to prevent compression of the neural tissues, distraction of the adjacent vertebral bodies providing increased room in the intervertebral foramina and stability of the spine.
