Percutaneous transluminal angioplasty (dilatation) of carotid, vertebral, and innominate artery stenoses.

Over a period of 5 years, 51 stenoses of brachiocephalic arteries were successfully dilated, and one subclavian occlusion recanalized in 42 patients. Among 24 patients there were 21 stenoses of the internal carotid artery, two stenoses of the common carotid artery, two stenoses of the innominate artery, five stenoses at the origin of the vertebral artery, and four stenoses of the subclavian artery. There were 17 patients who had stenoses of the subclavian artery. In 12 cases several arteries were affected. In 9 patients multiple (2-3) stenoses in these supraaortic arteries were dilated. In 4 cases bilateral dilatation of internal carotid arteries was performed. There were transient, minor complications in 2 patients.

[Results of percutaneous transluminal dilatation of cerebral vascular stenoses].

The present paper is a review of 37 successful catheter dilatations of supra-aortic vascular stenoses. There were sixteen patients with a total of 21 stenoses of the internal carotid, vertebral artery or common carotid artery and sixteen patients with subclavian stenoses. Amongst the patients with stenoses of the cerebral vessels, there were ten with multiple lesions and six with a single stenosis. Three patients had successful dilatations of bilateral stenoses. The indications, technique, and complications of catheter dilatation of lesions of the cerebral vessels are described and discussed.

[111Indium-thrombocyte scintigraphy and percutaneous transluminal dilatation (angioplasty) of supra-aortic vascular stenoses. A new method for deciding therapy and for follow-up control].

Scintigraphy with 111indium-marked autologous platelets has been used during percutaneous transluminal dilatation of supra-aortic arterial stenoses; there were 14 successful dilatations and one attempted dilatation. The material consisted of nine stenoses of the internal carotid artery, two stenoses at the origin of the vertebral artery and four stenoses of the first part of the left subclavian artery. Deposition of thrombi could be demonstrated by scintigraphy, both before and after catheter dilatation. The value of this method for deciding on the type of treatment and for observing the course of percutaneous dilatation of cerebral vessels is discussed.

[Percutaneous transluminal dilatation (PTD) of descending stenoses of the vertebral artery].

38 stenoses of supra-aortic arteries were dilated with good success in 32 patients over a period of four years. They were 17 stenoses of the internal carotid artery, one of the common carotid artery, 16 of the subclavian artery, and four descending stenoses of the vertebral artery. Indication, method, and results of percutaneous transluminal dilatation of stenoses descending from the vertebral artery are described and discussed, with reference being made to case examples.

[Therapy of giant aneurysms in the region of the base of the skull].

The introduction of microsurgical techniques has given a new impetus to operative therapy of cerebral aneurysms. Method of choice is clip occlusion of the aneurysmal neck, but this goal cannot always be attained. Usually, fusiform shaped aneurysms and so-called giant aneurysms can only be treated by occlusing the feeding vessels. In such cases the preliminary extra-intracranial bypass provides optimal conditions for interrupting the main feeder. Special points of view regarding these rare aneurysms and their haemodynamic relationships to cerebral circulation are discussed. A therapeutical concept is proposed on the basis of three case reports.

[Angiographic diagnostics of extracerebral haematomas (author's transl)].

This paper deals with 492 patients suffering from cranio-cerebral injuries. Intracranial haematomas were assumed to exist. The angiographic findings were compared with operation reports and postmortem findings respectively. It could be stated that extracerebral haematomas were detected by angiography in a percentage of more than 95.

[Significance of angiographic diagnosis in soft tissue tumors of the extremities].

Diagnostic angiography was carried out in 50 soft tissue tumors--23 benign and 27 malignant--of the extremities. All of the malignant tumours could be diagnosed correctly. We obtained false positive results in 2 benign tumours and in 5 inflammatory processes. These cases showed several criteria of malignancy. Angiographic diagnosis is important for the definition of the place of excision for histological examination. Combined use of angiography and computed tomography seems to be the optimal diagnostic procedure in the pre-operative phase.

[Complications following cerebral angiography. Report on 4181 cerebral angiographies].

Complications of 4181 cerebral angiographies performed from 1973 to 1978 in 2365 patients were analysed. In 13,6% of the patients temporary complications could be observed. In 3,1% temporary neurologic-psychiatric complications occurred, most of them in patients of younger age and in the presence of diffuse cerebrovasuclar disease. There was a permanent damage in 0,21%.
