Differences between CS-DAVF and TCCF——to reveal and redefine CS-DAVF
摘要
In the past, the cavernous dural arteriovenous fistula was categorized as spontaneous cavernous carotid fistula [1] due to the lack of knowledge and limitation of imaging equipment. In the recent time, with the accumulation of knowledge of DAVF's etiology, mechanism, physiology, clinical symptoms and imaging data, the diagnostic methods and treatment have achieved novel understandings and progresses. In fact, it's a specific type of dural arteriovenous fistula---- cavernous dural arteriovenous fistula. The purpose of this paper is to tell the difference between cavernous dural arteriovenous fistula and traumatic carotid cavernous fistula, and to redefine cavernous dural arteriovenous fistula from the aspects of etiology, mechanism, pathology, clinical symptoms, DSA characteristic and therapy. DAVF is an independent disease. The Cavernous dural arteriovenous fistula can not be classified as spontaneous CCF any longer, but a specific type of DAVF--- cavernous DAVF.
