Advances in endovascular treatment for intracranial aneurysms
The occurrence of craniocerebral aneurysm is mainly due to the outward cystic swelling of the intracranial artery wall under the influence of hemodynamics.Rupture of intracranial aneurysm is a main cause of subarachnoid hemorrhage,second only to ischemic cerebrovascular embolism and hemorrhagic cerebrovascular accidents caused by hypertension,and is one of the common diseases in cerebrovascular neurosurgery.The disease tends to occur in middle-aged and elderly people between 40 and 70 years old,and the onset is sudden,disabling,with a high fatality rate,often bringing serious economic burden to the society and the family.Foreign scholars have been constantly carrying out further researches on the treatment of the disease.Serbinenko first proposed the endovascular treatment of aneurysms in the 1970s,but it was limited by the high requirements and lack of interventionary materials.It was not until the 1990s that Guido Guglielmi invented the detachable spring coil,which made a breakthrough in the treatment of intracranial aneurysms.With thecontinuous progress of modern science and technology,endovascular intervention materials and technologies have also undergone earth-shaking changes,and people have gradually understood the superiority of minimally invasive intervention in the treatment of endovascular diseases.This article mainly reviews the development of interventional materials and techniques for intracranial aneurysms.
