SUMMARY
A Cerebral Arteriovenous Malformation is an abnormal connection between arteries and veins. In the healthy cases, the blood flows from arteries to veins through capillary bed. But patient having AVM, the capillary bed will be absent. The veins cannot handle the pressure of blood flowing from arteries to veins and it ruptures. The success of treatment by embolization in interventional Neuroradiolgy is highly dependent on the accuracy of the vessels visualization and quantification. In this paper, we have done simulation, quantification of tortuous vessels, which is a part of NIDUS using 3DRA for cerebral patients, so that the doctors can analyze and decide the mode of treatment.
