Do we need variable pressure shunts?

We describe our experience using a variable pressure cerebrospinal fluid shunting system, over a period of 5 years. These valves appear to be reliable and have the advantage of allowing pressure setting adjustments to be made in the out-patient clinic. An analysis of the cost-effectiveness of this system, allowing for materials, theatre time and hospital stay, suggests that over pounds 21,000 was saved, by avoiding shunt revision procedures, over this period.

Untoward clinical effects after stereotactic radiosurgery for intracranial arteriovenous malformations.

Stereotactic radiosurgery has become one of the most acceptable means of treating deep-seated intracranial arteriovenous malformations, as well as being a useful adjunct in a number of other pathologies. One hundred and sixty patients are discussed, having follow-up of at least 2 years. Radionecrosis occurred in six patients and haemorrhage in the latent period prior to thrombo-obliteration in a further six. Successful thrombo-obliteration was ultimately achieved in 76% of patients. As a bonus, epilepsy was improved in 29 of 48 patients presenting with seizures and worsened transiently in only three of these.

Intraoperative ultrasound-guided biopsy of intracranial lesions: comparison with freehand biopsy.

Achieving the required accuracy during such relatively straightforward procedures as tumour biopsy or abscess aspiration remains a challenge especially for the more junior neurosurgeon. A study comparing freehand biopsy with ultrasound-guided biopsy is presented. The use of intraoperative ultrasound increases the accuracy at the expense of a slightly longer operating time. Diagnostic tissue was always obtained using this technique.

The value of intraoperative ultrasound in neurosurgery.

Intraoperative ultrasound is not a technique which has been widely accepted by neurosurgeons in this country, not least because bulky probes and machines become more of a hindrance than an asset in theatre. The development of new smaller probes, including ones small enough to visualize the brain through a conventional burr-hole has rekindled interest in this subject. Its use for guidance in tumour biopsy, cyst aspiration and catheter placement, as well as volume estimations and determining the completeness of tumour resection, are outlined. The ability to recognize peri-operative haemorrhage is demonstrated.

Gas gangrene occurring soon after compound depressed skull fracture.

Two cases of Clostridium perfringens infection occurring less than 24 hours after compound depressed skull fracture are reported. The infection was principally intracranial in the first and extracranial in the second; both required surgical debridement and antibiotic treatment. Attention is drawn to the rapidity with which a potentially life-threatening infection can develop in civilian head injury and to the implications for acute management of patients with compound depressed fractures.
