[Repetitive syncopale loss of consciousness by properly functioning pacemaker. Ophthalmodynamographic, ophthalmodynamometric, and cerebral-scinitigraphic investigations (author's transl)].

In spite of an intact pacemaker function, 3.8% of 444 patients with an implanted cardiac pacemaker taking part in a regular follow-up program had repetitive syncopes. The investigation thereafter, whether or not these attacks were symptoms of occlusive vascular disease of the carotid arteries, included a thorough physical and angiological examination, ophthalmodynamometry (ODM), ophthalmodynamography (ODG), and radionuclide angiography.

[Carotico-cavernosus fistula after subclavia-carotis interna bypass (author's transl)].

A case of occlusion of the right common carotid artery combined with stenosis of the left common carotid artery is reported. Immediately after surgery a carotico-cavernosus fistula was observed on the right side. The clinical picture and the therapeutical problems are discussed; 4 X-ray and 2 fundus photographs are presented.
