This sequel to Dr. Lawton's best-selling Seven Aneurysms focuses on microsurgical resection techniques for AVMs found in the lobes and deep regions of the brain. It categorizes the techniques into subtypes to simplify the broad spectrum of brain AVMs neurosurgeons may encounter. The book is organized into three sections: The Tenets, which establishes eight steps for AVM resection; The Seven Arteriovenous Malformations, which describes the anatomical terrain and surgical strategies for thirty-two AVM subtypes; and The Selection section, in which Dr. Lawton discusses what he believes to be the keys to successful AVM surgery: good patient selection and best application of multiple treatment modalities.
