Abstract

Introduction: Dural arteriovenous fistula (DAVF) is an abnormal connection of vessels
in the tissues around the brain or spinal cord. Exact etiology of DAVF is not
known.They can cause multiple symptoms as per location and presents with
Haemorrhages. Diagnosis - Includes CT and MR,dynamic CTA, MRA or
DSA.Treatment ranges from conservative treatment to endovascular therapy, surgery,
and Radiation therapy.
Aim and Objectives: Tostudy aetiology,clinicaland radiologicalfeaturesandmanagement
ofDural Arterio-venousfistulae.
Methods: Total 33 patients of DAVF studied which divided in three groups as ncsDAVF
(18), csDAVF (8) and spinal DAVF (7) and were investigated and treated as per
radiological finding.
Results: Mean age of presentation of ncsDAVF is 44 years, csDAVF is 37 years and
spinal DAVF is 56 years. Male preponderance present in both. In intracranial DAVF, in
spinal DAVF, thoraco-lumbar region is the most common site. On angiographic follow
up of 11 Onyx treated patients, 10 patients were achieved complete cure (90.9%) in a
single session(9.09%).
Conclusion:In csDAVF, endovascular treatment has good results,In spinal DAVFalso
endovascular embolisation using Glue+ lipoidal solution. complete occlusion is seen.
