Intracranial Aneurysms and Vascular Malformations: Diagnosis and Therapy. A Long-Term Study at a Central Hospital. Part I: 1972-1997. The Time before Endovascular Intervention, Microneurosurgery and Radiotherapy.

The first part of our study describes the treatment of our patients with intracranial vascular malformations (aneurysms/AVMF - arteriovenous malformations) in a region of about 500,000 inhabitants. The second part will compare currrent treatment and the changes in treatment (microsurgery, endovascular interventional techniques, etc.) also in relation to topography and demography.
