Thread occlusion but not electrocoagulation of the middle cerebral artery causes hypothalamic damage with subsequent hyperthermia.

Moderate changes in body temperature can influence the outcome of cerebral ischemic insults and the effect of drugs. Body temperature was measured continuously for 24 hours in rats subjected to permanent occlusion of the middle cerebral artery (MCA) by either coagulation or thread insertion, and the results correlated with the histology of the hypothalamus. The body temperature did not change after MCA occlusion by coagulation and the hypothalamus was intact in all rats. In contrast, the body temperature rapidly increased from about 38 degrees C to more than 39.5 degrees C after MCA occlusion using intraluminal thread, and hyperthermia continued for at least 6 hours in all rats. Histological evaluation revealed neuronal damage in the preoptic area of the hypothalamus in all rats undergoing thread occlusion. Long duration hyperthermia must be prevented after permanent MCA occlusion when the intraluminal thread occlusion model is used in chronic experiments.

Tubal sterilization. With special reference to electrocoagulation through the laparoscope.

In the past 5 years 1 168 tubal sterilizations have been performed. One thousand and twelve of these were performed by dividing the tube by diathermy through the laparoscope. Since the first cases, and with increasing experience, complications have been infrequent, at the most a slight bleeding from the mesosalpinx. So far we have had ten failures, probably due to lack of experience. In every failure it was found at re-examination that the tube had not been divided-at least at one side. The method is quick and simple. The patient suffers little inconvenience, has a very small scar and is in hospital only a short time. It has been used in post-partum cases, but is not suitable for patients who have had several abdominal operations.

A comparison of effects of bipolar and monopolar electrocoagulation in brain.

Controlled bipolar and monopolar coagulation lesions were generated in the cerebral cortex of cats. Higher output powers were associated with larger lesions, while the lesion size was independent of the mode of coagulation. When cortical vessels were mobilized and coagulated for hemostasis, bipolar mode was associated with more rapid coagulation and less damage to the underlying brain. Higher output powers were not associated with larger lesions, probably because coagulation was more rapid. The neural damage resulting from radiofrequency current appears to be of thermal origin, and the blood-brain barrier dysfunction is a more sensitive measure of this damage than the stainable cellular changes.

Percutaneous electrocoagulation of the trigeminal nerve using CT guidance. Technical note.

Computerized tomography guidance can be used during placement of an electrode for the ablation of the trigeminal nerve or gasserian ganglion. A combination of a scout view and axial images through the skull base provides adequate visualization of the needle and foramen ovale. This method is recommended in patients who cannot be properly positioned for fluoroscopy or when there is poor visualization of the foramen on conventional radiographs.

Treatment of Morton's neuroma using percutaneous electrocoagulation.

A new modality for treating Morton's neuroma was introduced and performed by the authors, using a nerve lesion generator. Seventy-nine lesions were evaluated by obtaining the patients' responses to three questions. By rating their symptoms on a 0-5 scale both before and after the neurectomy, the patients showed a 56% reduction in symptoms. With a gone-improved-same-worse rating, the patients responded with 25%, 46%, 24%, and 5% in each respective category. The overall assessment of the procedure by the patients yielded 68% pleased and 32% not pleased. An average of 4 hr was missed from work following the neurectomy, and only 20% of the patients required mild analgesics.

[Bipolar electrocoagulation of red spider veins and telangiectasis of the face].

The development of a patented bipolar "coagulation fork", applied in combination with a customized microprocessor-controlled high-frequency unit, constitutes a break-through in the treatment of very small varicose veins of less than 0.5 mm in diameter, commonly described as spider veins, that cannot be removed through sclerotherapy. The technique is quite simple and does not require any kind of anesthesia. It is also best suited to treat teleangiectases on the face. Follow-up treatment is not required.
