ObjectiveTo observe the prognosis in patients with posterior communicating artery aneurysm treated with endovascular embolization, and to explore the risk factors affecting its prognosis. MethodsThe clinical data of 60 patients with posterior communicating artery aneurysm were retrospectively analyzed, and all underwent endovascular embolization. The embolization effect and prognosis were observed, and the risk factors affecting prognosis were analyzed in patients. ResultsThe Raymond classification instantly after embolization was as follows: total embolization in 36 cases, nearly total embolization in 18 cases, and partial embolization in 6 cases. Forty-two cases achieved favorable prognosis and 18 cases had poor prognosis. There were statistically significant differences in aneurysm diameter, operation timing, preoperative Hunt-Hess classification, presence of postoperative cerebral infarction between the two groups (all P＜0.05). Multivariate logistic regression analysis revealed that large aneurysm diameter, operation timing more than 14 days, high Hunt-Hess classification before operation, and postoperative cerebral infarction were the independent risk factors affecting prognosis in patients with posterior communicating artery aneurysm (all P＜0.05). ConclusionPatients with posterior communicating artery aneurysm treated with endovascular embolization achieves a preferable prognosis; in addition, attention should be paid to the effects of the factors on prognosis in patients, such as large aneurysm diameter, operation timing more than 14 days, high Hunt-Hess classification before operation, and postoperative cerebral infarction.
