[Own experience with the treatment of intracranial aneurysms using "Perneczky" - Zeppelin clips]

The basic design and the mechanism of clip application have not changed for many years. However in cases of aneurysms located deeply inside brain structure, in narrow spaces, multiple aneurysms or those which require applying of several clips the surgeon may have problems with visual control of the position of the clamping arms on the neck of aneurysm, nearby blood vessels and nerve structures. The above mentioned problems motivated prof. Axel Perneczky to construct a new model of clip with an applying and a removing holder whose mechanism is based on the principle of inverted--spring. Between February and August 1998 in the Neurosurgical Clinic in Katowice, 12 Perneczky's clips were applied in 9 patients. Intraoperative complications were not observed in any of the cases. In two cases of aneurysms located on the bifurcation of the basilar artery, application of two clips enabled precise intraoperative control of clip position.
