patients under the age of 18 years with arteriovenous shunts manifested by systemic or neurological manifestations will undergo endovascular embolization

Outcomes

Primary Outcome Measures

Independent clinical outcome changes
The changes in clinical condition of the patients will be assessed before and after treatment using modified Rankin scale, as the scale runs from 0-6, running from perfect health without symptoms to death. 0 - No symptoms. - No significant disability. Able to carry out all usual activities, despite some symptoms. - Slight disability. Able to look after own affairs without assistance, but unable to carry out all previous activities. - Moderate disability. Requires some help, but able to walk unassisted. - Moderately severe disability. Unable to attend to own bodily needs without assistance, and unable to walk unassisted. - Severe disability. Requires constant nursing care and attention, bedridden, incontinent. - Dead.

Secondary Outcome Measures

Radiological outcome:
CT angiography or MR angiography will be done to show complete or in complete occlusion of the AV shunt

5. Study Description

Brief Summary
Review the outcomes of the Endovascular management of pediatric intracranial arteriovenous shunts. Give an effective treatment for pediatric intracranial arteriovenous shunts and can detect the best method could be used and assess safety and efficacy of different endovascular techniques in treatment of different AV shunts. Improve the outcome of these patients and decease rate of recurrence and complications.
Detailed Description
Intracranial arteriovenous shunts (ICAVS) in young children are characterized by frequent high-flow fistulas. In association with high-flow fistulas and the physiological condition of the developing brain and heart, each ICAVS type tends to present at a certain age with unique symptoms. Vein of Galen aneurysmal malformation (VGAM) and dural sinus malformation with arteriovenous (AV) shunt tend to present in the neonate with high output cardiac failure. In infancy, VGAM, pial arteriovenous fistula (AVF) and infantile dural AVF (DAVF) tend to present with hydrodynamic disorder such as macrocephaly, ventriculomegaly, prominent facial veins, and developmental delay. Pial AVF, AV malformation, and infantile DAVF can present with focal neurological signs such as seizure or hemorrhage at older ages they are in the subpial space, as opposed to VGAM or DAVF, which are extrapial in location and tend to present with systemic symptoms . Endovascular treatment is currently the first choice of treatment for most pediatric ICAVS. The treatment goal should be defined on a patient-by-patient basis, according to the unique physiological condition of the child.
