RESUMO
After rapid development over the past few years,interventional neuroradiology has become an important branch of mini invasive neurosurgery,it brought new methods and approaches in the treatment of intracranial aneurysms,intracranial arteriovenous malformations,duramater arteriovenous fistula,ischemic cerebrovascular diseases and so on.Particularly,the technique has also made impressive headways in the embolization of intracranial wide necked aneurysms and development of new embolizing materials.To accelerate its development,more emphasis should to be put on the basic theories of interventional neuroradiology,and more efforts should be made to develop new techniques,new materials and new equipments in the area.Finally,doctors should be trained and the manipulation regulations and quality control system should be established.
