Preface

The operative treatment of vascular malformations using microsurgical techniques began in Zurich in January 1967. During the next 20 years, 414 patients with AVM of the brain and 71 with spinal AVM have been treated surgically. In the same time period 86 patients with cerebral AVM were discharged from our department without operation: In 40 cases the AVMs were operable but the patients refused surgery; in 24 cases the risk of neurological deficits delayed the decision for operative intervention until a later time; in 22 cases (22/500 = 4.4%) the lesion was deemed inoperable.

The present volumes III A–III B are intended to relate and analyze our experience gained in the evaluation of 414 operated and 86 nonoperated patients with intracranial AVMs, to review what has been accomplished before and since the advent of microsurgical techniques and to identify the problems remaining in the treatment of these often difficult lesions. Other operated intracranial vascular lesions such as cavernomas (22 cases) and venous angiomas (5 cases) of the brain are also covered briefly. Interventional neuroradiological and surgical procedures for the treatment of cranial dural, spinal dural and medullary AVMs, and of carotid-cavernous fistulae are not included and will form separate subsequent monographs.

The third volume, part A, contains:

History, embryology, pathological considerations, hemodynamics, Doppler-techniques, neuroradiology, neurosurgical anatomy, microcirculation, anatomy of the calcarine sulcus.

The third volume, part B, contains:

General operative techniques, the specific treatment and results of surgery for AVMs of specific locations like convexial (frontal, temporal, insular, parietal, occipital and cerebellar) and deep central (limbic system, corpus callosum, striocapsulothalamic, meso-diencephalic, vein of Galen, splenial, plexal, pontine), special and general statistics regarding morbidity and mortality, complications, the follow-up of nonoperated cases, and a chapter concerning the cavernous and venous angiomas and finally a chapter on neuroanesthesia technique, as utilized in Zurich.
