The study includes a series of 39 patients with AVM of the brain that are not subjected to any method of treatment, except for the symptomatic treatment who were hospitalized and diagnosed AVM at the Institute of Neurosurgery, Clinical Center, in the period 2005-2011. Results: The structure of the patients was measured by gender are male. Average age of the respondents was 27.4 ? 7.6 years. With the average length of the follow-up of 4.8 years, new hemorrhage occurred in 24 patients (58 episodes). Predictor (p<0.01), factors for bleeding include: arterial supply from the VB and ACA basin and multiple arterial supply. Conclusion: The analysis of our series may be proposed for following model of the natural course of AVM : After initiall haemorrhage there is annual risk of rehemorrhage of 3.33%. Bleeding events were significantly more common in medium-sized AVM (2.5 - 5 cm), localized in elocvent area of the brain with combined type of venous drainage, arterial supply from the vertebrobasilar artery, anterior cerebral artery basin or combined arterial supply.

Introduction. Intracranial aneurysms are very rare in the pediatric population . Very rarely they are accompanied by subarachnoid hemorrhage (SAH). As in the adults they are most often discovered after their rupture. Case report. We report the case of a child 14 months old at the time of rupture of the aneurysm , which led to intraventricular hemorrhage and accompanied by left side body weakness. After diagnosis - digital subtraction angiography (DSA) aneurysm on the posterior chorioid artery was verified. Consultatory there was no decision for surgical treatment. The child is now 6 years old, there is a discrete left side pyramidal deficit , control DSA - finding stationary. Conclusion: Despite the development of modern diagnosis of intracranial aneurysms their treatment is still a big challenge. Child?s brain has great recovery potential, which encourages aggressive therapy for these disorders and provide good results. In younger patients with ruptured aneurysms and vascular anomalies associated with neurological deficit, where surgical treatment or endovascular procedures associated with the high risk of complications, conservative treatment is indicated.

Multidetector computed tomographic angiography (MDCTA) is a non-invasive, highly sophisticated and readily available diagnostic method nowadays gained primacy in the algorithm of the blood vessels of the brain. MDCTA showed the highest sensitivity and specificity for early detection of ruptured intracranial aneurysms. Saccular aneurysm geometry (shape and size), anatomic localization, and patient-dependent factors individually and together determine the risk of rupture of the aneurysm. Unruptured aneurysms in anterior communicating artery showed twice the possibility of rupture than other intracranial aneurysms. Clinical history ACoA aneurysms after rupture is particularly difficult. This justifies the efforts to determine the real risk of these aneurysms when SAH was not found on the native scan endocranium. It is here that the diagnostic value and usefulness of MDCTA examination increases significantly and its true dimension.

Introduction. We report a series of 30 patients with spontaneous intraventricular hemorrhage (IVH) and hydrocephalus, in which is placed subcutaneous (Omaya) tank at the University Children?s Hospital in Belgrade from March 2006 to March 2011. Results. Predictors of poor outcome in treatment in getting Omaya reservoirs are low birth weight (t=2.560, p=0.016), low Apgar score (t=3.059, p=0.005), an extended number of days on mechanical ventilation (Z=4,404 , p< 0.001), the presence of peripartal asphyxia (X2=9.977, p=0.002) and cardio-respiratory arrest (X2=12.804 , p< 0.001). Conclusion. The outcome of treatment of hydrocephalus caused by spontaneous intraventricular hemorrhage in premature infants is worst in perinatology. There is no consensus on the diagnosis and treatment of posthemorrhage hydrocephalus, our results suggest that the main prediction factor is preoperative condition of the child.

In tro duc tion: The ob jec tive of this study was to dem on strate the pre dic tive value and the presence of di ag nos tic comorbidity and perioperative fac tors in the out come of shunt sur gery for hydro ceph a lus. Meth ods : We ret ro spec tively an a lyzed a se ries of 32 pa tients who un der went sur gery for NTH on Neurosurgical Ser vice KBC Zemun in the 2006-2012 pe riod year. Di ag nos tic fac tors were an alyzed: clin i cal signs (gait dis tur bance, cog ni tive def icits and in con ti nence), Ev ans' in dex and lum bar punc ture. Perioperative comorbidity fac tors an a lyzed were: ar te rial hy per ten sion, di a be tes mellitus, and cerebrovascular in sult. Re sults: Of the to tal of 32 op er ated pa tients had gait dis tur bance, cog ni tive def i cits 24 and 23 uri nary incon ti nence. Im prov ing gait dis tur bance had 20, 13 had cog ni tive def i cits and 11 uri nary in con ti nence. Im prove ment of gait dis tur bance was sig nif i cantly differ ent (p<0.05) than the other two im prove clin i cal signs. Of the fac tors of perioperative comorbidities , hy per ten sion was the most com mon 24, with di a be tes mellitus showed a sta tis ti cally sig nif i cant pre dic tor of un fa vor able out come (p = 0.029). Con clu sions: gait dis tur bance proved to be the most com mon di ag nos tic NTH fac tor and the fac tor that has the best prog no sis in pa tients op er ated for NTH , while DM is the most com mon fac tor of perioperative comorbidities .
