Abstracts of the Seventh Annual Stonwin Medical

s of the Seventh Annual Stonwin Medical Conference-Endovascular lnterventional Neuroradiology Sponsored by the Harry Winston Research Foundation, Inc., Held at Stonwin, Scarsdale, NY, July 10-12, 1989 The concept of the Stonwin Medical Conference originated with Harry Winston and his wife, Edna. Their support of medical and scientific technological development was well recognized. These efforts were continued by their sons Ronald and Bruce through the formation of the Harry Winston Research Foundation, Inc. A collaboration with the Department of Neurosurgery of the New York Neurological Institute under the directorship of Bennett M. Stein, provided a firm academic atmosphere. In this setting, the first conference was held July 14-15, 1983. It was an immediate success. Subsequently , guests from Europe, the Soviet Union, Japan, and the People's Republic of China contributed enormously to the subjects under discussion. In 1986, an agreement was signed to promote scientific and medical collaboration between the N. N. Burdenko Neurosurgical Institute under the directorship of A. N. Konovalov, the Department of Neurosurgery of the New York Neurological Institute, and the Harry Winston Research Foundation. An exchange program for students and fellows in neurosurgery began in the spring of 1988 and is expected to continue without interruption. This year's topic-Endovascular lnterventional Radiology-was proposed by Professor Konovalov. The group assembled for the conference included the majority of experts engaged in challenging the frontiers of interventional radiology. We were proud to have Juan M. Taveras as our guest of honor and moderator. The conference and its discussions were unprecedented in demonstrating the success and validity of this newest technology and brought to the forefront the problems that must be faced and overcome to ensure future development in this field . Brief abstracts of the talks are presented here. A complete text with detailed discussions and illustrations will be published by Plenum Press in 1990. lnterventional neuroradiology. Taveras JM (Massachusetts General Hospital, Harvard Medical School, Boston, MA 02114). Neurologic surgery is a relatively young subspecialty of general surgery. Aside from emergency evacuations of epidural and subdural hematomas, which go back to ancient history, no attempts to remove lesions such as neoplasms of the brain and spinal cord were publicized until 1879 and 1884, for the brain , and 1887, for the spinal cord . This led many general surgeons, as many as 500, to publish Codirectors Robert N. N. Holtzman Downstate Medical Center, State University of New York
