Abstract

Endovascular treatment of Intracranial aneurysms (IAs) is associated with less invasiveness and lower morbidity compared with microsurgical clipping. Aim: to assess incidence of recanalization after endovascular management of intracranial aneurysms by at least 6 months follow-up as well as to assess the need for re-embolization. Methods: The study included 89 patients presenting with intracranial aneurysms whether ruptured or unruptured referred to the interventional neuroradiology unit for endovascular treatment. All procedures performed at Nasser institute hospitals on a monoplane angiography system (Philips Allura FD imaging system). All patients were treated by endovascular embolization between 2017 and 2020 with follow up angiography to the following management protocol. Results: In our study 5 cases from 89 cases developed procedure related complication (5.6%) in the form of: 1 case developed intraprocedural rupture (1.1%), 4 cases developed thromboembolic complications. (4.5%). Six months at least follow up control conventional angiography was done to assess recanalization and the need for re-embolization was reported. Follow up period ranged from 7 to 14 months with mean of 10.75 ± 1.89 months. During the follow up period 21 (24%) patients had recanalization after the endovascular management. During the follow up period none of the recanalized aneurysms presented with rebleeding after treatment. Recanalization was observed in 25 % of ruptured aneurysms and 17 % of unruptured aneurysms. Recanalization was observed in 22% of small aneurysms, and aneurysms and 37% of large aneurysms. Recanalization was observed in 18% of aneurysms with favourable SNR, and in 30 % of aneurysms with unfavourable SNR. Conclusion: there were a higher incidence of recurrence in ruptured aneurysms, , aneurysms more than 10 mm, and wide neck aneurysm, however it was not statistically significant. That may be attributed to small number of cases and the short period of the study. Our study also showed that there was no influence of using the remodeling techniques in on the recurrence of the endovascularly treated aneurysms this also may be due to small number of cases treated with remodeling technique in our study. In our study some risk factors affecting the recanalization such as the location of the aneurysm could not be assessed due to small number of cases in some locations
