A technique of diathermy sclerosis of varicose veins.

Abstract: A technique of multiple site percutaneous diathermy ablation of saphenous tributaries in 98 limbs on 61 patients (females 42; males 19) is described, and the results are reported.

A bipolar coaxial microprobe for safe transvitreal diathermy.

Abstract: • We present a new 22-gauge transvitreal bipolar diathermy microprobe. With the use of the coaxial principle, the current flows only at the probe's end surfaces. Because of its small size and end-on coagulation effect, and when used in conjunction with a low-frequency diathermy unit, the probe can be used safely on vessels lying directly on the retinal surface and close to the optic nerve head. We report three cases to demonstrate the usefulness of this instrument.

Histopathologic evaluation of adhesive properties of early lesions in diathermy and cryopexy

Abstract: We examined the histopathologic appearance of both cryopexy and diathermy lesions, ten to 60 minutes after application in the rabbit retina. Both lesions showed immediate subretinal fluid accumulation. Thus we would not substantiate the speculation that a diathermy lesion might have greater immediate adhesive strength than a cryotherapy lesion. This explains the clinical experience that retina tends to slip with either modality when trying to treat giant retinal tears.

High-Frequency Electrosurgical Treatment of Tracheal Obstruction Using the Flexible Bronchofiberscope

Abstract: Endoscopic electrosurgery with high-frequency diathermy has been developed since 1970, and employed widely in the field of gastroenterology, especially for polypectomy. Since 1978, we have been applying this high-frequency diathermy technique through the flexible bronchofiberscope as palliative treatment of tracheall obstruction.

Bipolar Bimanual Diathermy

Abstract: To the Editor. —In an article in theArchives(1981;99:494-497), Parel et al alleged that bipolar bimanual diathermy was potentially unsafe. While no concerned clinician can fault a search for safety, I believe that the authors had no case report of damage caused by this method and had performed no animal experimentation either with bipolar bimanual diathermy, which they disagreed with, or the method that they recommended as being safer. They report only three cases with their method, which certainly does not prove that it is safer. The method of bipolar bimanual diathermy has been in use for six years worldwide by more than 300 clinicians of whom I am aware. I have used the method in more than 500 patients in a near 3,000-case series of pars plana vitrectomy. I have never experienced changes in the sclera or vacuoles in the lens that would be the early findings of

Histopathologic evaluation of adhesive properties of early lesions in diathermy and cryopexy.

Abstract: We examined the histopathologic appearance of both cryopexy and diathermy lesions, 10-60 min after application in the rabbit retina. Both lesions showed immediate subretinal exudation. Thus, we could not substantiate the speculation that a diathermy lesion might have greater immediate adhesive strength than a cryotherapy lesion. This explains the clinical experience that retina tends to slip with either modality when trying to treat giant retinal tears.

Microwaves in medicine

Abstract: Microwave techniques can be applied to diagnose malignancies such as cancerous tumours, cardiac condition, pulmonary oedema and thickening of arteries. Therapeutic applications involve heating of cancer tissues to lethal temperatures (hyperthermia) and heating of subcutaneous afflictions to enhance healing and to provide pain relief (diathermy) using microwave radiation
