Abstract
Summary The use of endovascular therapy (EVT) in the management of cerebral AVMs has taken a big step forward in the last decade especially after introducing the new non-adhesive polymer ethylene vinyl alcohol (EVOH) for the AVMs’ nidal obliteration and the use of the detachable tip microcatheter making the procedure easier and safer. In this study, we reviewed the angiographic anatomy of the cerebral AVM including the geometric classification of feeding arteries, the angioarchitecture of the nidus, and the angioarchitecture of the lesion’s venous compartment. Following this; classification, grading systems, and clinical presentation of cerebral AVMs were clearly and thoroughly reviewed. Moreover, radiological investigations of cerebral AVMs were discussed revealing all their pros and cons in the process of diagnosing the disease. The study also discussed management modalities of cerebral AVMs including conservative management, endovascular embolization, microsurgical resection, and stereotactic radiosurgery with their pros and cons stressing mainly on the endovascular embolization and its role in treating cerebral AVMs in the pediatric population. The study was conducted on 20 patients. The majority of them were males ranging from 2-18 years with a mean age of 10.6. No patient in this study had a family history of cerebral AVMs. 18 patients in the study were presented with intracranial hemorrhage while 2 patients only were presented with intractable seizures that
