Abstract
Patients with brain arteriovenous malformation (AVM) have a certain risk to bleed, and the goal of this study is to examine the
effect of radiological and clinical predictive characteristics of AVM hemorrhage using multidetector CT angiography (MDCT).
Material: this is a series of 57 patients with a mean age of 35.46 years, who were diagnosed at the Institute for Radiology and MRI,
while the same were hospitalized at the Clinic of Neurosurgery, Clinical Center of Serbia in the period from January 2008 to March
2016. For all patients, the diagnosis was made using MDCT angiography. Two groups of patients were observed. The first group
includes patients who were not initially presented by hemorrhage, while the second group was initially presented by hemorrhage.
Both groups were treated with medical therapy, or a combination of medical therapy with embolization / surgery / radiotherapy.
Results: Deep venous drainage (p <0.05), the combined arterial supply from different basins (p <0.05) with a length> 60mm, venous
dilation present in the drainage vein (p <0.01) and the angle of casting supply arteries in the nidus (p <0.01), carry a risk of repeated
bleeding. In the group of patients who had initial hemorrhage a mean value of the sized corner casting was 130o, while the group that
did not had initially bleeding mean value of the size of the measured angle was 103.81 with a standard deviation of 17.21 (p <0.01).
Conclusion: arterio-venous malformations with the deep venous drainage from the carotid and VB basin, the length of the feeding
arteries> 60mm, angle of casting feeding arteries in the nidus ≥ 130 ° and dilatation and / or venous aneurysm drainage vessel are
predictive model for clinical presenting by hemorrhage.
