Follow-up Study Of Endovascular Embolization Treated Intracranial Aneurysms

BackgroundInterventional therapy of intracranial aneurysm began in the early1970of the20th century. With the fast development of technology and new embolism materials, the endovascular treatment of intracranial aneurysms has become one of the important ways. As a minimally invasive means of treatment, it’s safety and long-term effects still need to be further confirmed. And the major risk factors affecting prognosis of cerebral aneurysm, particularly factors associated with aneurysm recurrence and rebleeding still need to be further proved.Object i vesRetrospectively collecting the clinical data, clinical follow-up data and angiographic data of endovascular embolized intracranial aneurysms cases. To summarize the endovascular embolization curative effect as safety, efficacy, and prognostic factors.MethodsBy intracranial aneurysms after Endovascular embolization in the treatment of clinical follow-up of patients, understanding after embolization in the treatment of clinical prognosis; And through the radiographic follow-up, understand after embolization in the evolution of the aneurysm imaging. Assess the gender, age, history of hypertension, in patients with aneurysms, such as position and size effect of factors on prognosis of aneurysm embolism, X2test were used to statistically analyse relationship of the prognosis and gender、age、hypertension aneurysm neck. And on aneurysms in patients with Traditional Chinese Medicine syndrome differentiation and prognostic analysis of relationships.Result The gender of the aneurysm patients, aneurysm embolization degree and the aneurysm site, neck have no statistically significant effect (P>0.05); And the age of onset, history of hypertension, aneurysms size, ruptured aneurysm or not, H-H classification and the operation time have significant influence on the prognosis (P<0.05); Embolism volume ratio is not the only factor affecting recurrence, aneurysm neck coverage may be important factors in determining whether the aneurysm recurrent. ConclusionsThe result of this follow up study shows:1.Age、hypertention、aneurysm size、neck size、rupture or not、H&H scale and time of operation may significantly influent the prognosis.2. Posterior circulation aneurysms medium and large size aneurysm had a higher recurrent rate.3. Traditional Chinese Medicine syndrome of Yin-Yang class certificate has no effect on prognosis evaluation.4. Effective aneurysm embolization needs intraaneurysmal stasis and good neck coverage of the embolic.
