[Clinical significance of encycling clips in neurosurgery]

It is reported how, in 5 cases of arterial haemorrhage, the ligature of an artery was avoided by the use of Heifetz encircling clips with teflon liner. Two of the five patients had aneurysms. The remaining 3 were suffering from brain tumours. Postoperative computer tomography together with neurological follow up examinations indicated, that in two cases there was no disturbance of cerebral circulation. With a carotid angiography it was possible to show that in the other three cases normal flow through the arteries was maintained, 2, 11 and 45 days after emplacement of the clip.
