Analysis of influencing factors of recrudescence after endovascular embolization of intracranial aneurysms
摘要
Abstract
Objectives To study the risk factors for influencing recrudescence after endovascular embolization of intracranial aneurysms and to establish a regression model to predict the risk of recrudescence in patients with specific intracranial aneurysm after endovascular embolization. Methods From May 2012 to May 2014,429 patients (a total of 441 aneurysms)with intracranial saccular aneurysm who met the inclusion criteria and treated with endovascular embolization at the Cerebrovascular Treatment Center, Changhai Hospital,the Second Military Medical University were analyzed retrospectively. Multiple aneurysms were calculated separately according to per aneurysm. The aneurysms were divided into either a recurrent group (n = 66)or an unrecurrent group (n = 375)according to whether they had recrudescence or not. The differences of 11 factors such as clinical features,treatment technology and materials,and aneurysm anatomy of both groups were compared. Logistic regression was used to analyze the risk factors for recrudescence after endovascular embolization of intracranial aneurysms,and its effectiveness of predicting recrudescence was evaluated. Results There were significant differences in the size of aneurysms (χ2 = 46. 352,P <0. 01),rupture or not (χ2 = 4. 198,P = 0. 040),using stents or not (χ2 = 9. 554,P = 0. 002),and results of immediate postoperative embolization (χ2 = 10. 397,P = 0. 003). The results of multivariate logistic regression analysis showed that non-stent-assisted embolization (OR,4. 076,95% CI 2. 147 -7. 736,P <0. 01),Raymond grade Ⅱ (OR,4. 222,95% CI 1. 537 -11. 579,P = 0. 005),Raymond grade Ⅲ (OR, 4. 467,95% CI 1. 600 -12. 470,P =0. 004),large aneurysms (> 10 -25 mm)(OR,4. 914,95% CI 2. 277 -10. 604,P < 0. 01),and giant aneurysms (> 25 mm)(OR,35. 743,95% CI 3. 511 -363. 837,P = 0. 003) were the risk factors for recrudescence after aneurysm embolization. The effective test results of the regression model in predicting recrudescence showed that the area under the curve of the recrudescence predicting model was 73. 5% . Raymond grade was 56. 6%,and the non -stent embolization was 60. 1%,and the size of aneurysms was 40. 3% . Z test was used to calculate the differences of recurrent scores and non-stent embolization,Raymond grade,the area under ROC curve of aneurysm size. The Z values were 2. 662, 3. 513,and 6. 308,respectively,and the P values were 0. 007,0. 004,and 0. 001,respectively. Conclusions Large or giant aneurysms,non - stent - assisted embolization,incomplete embolization immediately after procedure were associated with the recrudescence after endovascular embolization of intracranial aneurysms. The established regression model may reflect the size of the recurrent risk.关键词
