Introduction Brain arteriovenous malformations (AVMs) are considered to be congenital, usually solitary anomalies of the central nervous system. The first descriptions of vascular malformations date from BC to the year [...]
Patients with brain arteriovenous malformation (AVM) have a certain risk to bleed, and the goal of this study was to examine the effect of radiological and clinical predictive characteristics of AVM hemorrhage using multidetector computed tomographic (MDCT) angiography. The study included a series of 57 patients, mean age 35.46 years, who were diagnosed during their hospitalization at Clinical Department of Neurosurgery, Clinical Center of Serbia, in the period from January 2008 to March 2016. In all patients, the diagnosis was made using MDCT angiography. Two groups of patients were observed. The first group included patients who did not initially present with hemorrhage, while the second group initially presented with hemorrhage. Both groups were treated with medical therapy or a combination of medical therapy with embolization/surgery/radiotherapy. Deep venous drainage (p60 mm, venous dilatation present in the drainage vein (p60 mm, the angle of the casting feeding arteries in the nidus [greater than or equal to]130[degrees] and dilatation and/or venous aneurysm of drainage vessel are predictive for clinical presenting by hemorrhage.
