| Abstract | OBJECTIVE: Type I spinal arteriovenous lesions represent dorsal dural arteriovenous fistulae with no spinal artery involvement. We report an exception to this and propose dividing Type I lesions into dorsal and ventral categories. METHODS: A 51-year-old patient presented with a partial Brown-Sequard syndrome. An angiogram revealed a spinal arteriovenous fistula, most prominently being fed a radicular artery arising from the right vertebral artery with only ventral venous drainage. RESULTS: This feeder was selected and embolized with onyx, however residual fistula persisted and the patient subsequently underwent microsurgical disconnection. At six-month follow-up, patient motor deficits have resolved and difficulty with proprioception is improving. CONCLUSION: Type I dural arteriovenous fistulae are associated with dorsal venous drainage. Our case demonstrates an exception to this. Recognizing this exception was crucial, because it allowed for simple microsurgical disconnection. We propose that type I dural arteriovenous fistulae be subdivided into ventral and dorsal based on their drainage pattern. This differentiation is critical because lesions with ventral drainage have traditionally been classified as type IV. These lesions have a different treatment method given involvement of spinal arteries. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
