Background: The objective of our project was to identify a late recanalization predictor in ruptured intracranial aneurysms treated with coil embolization. This goal was achieved by means of a statistical analysis followed by a computational fluid dynamics (CFD) with porous media modelling approach. Porous media CFD simulated the hemodynamics within the aneurysmal dome after coiling. Methods: Firstly, a retrospective single center analysis of 66 aneurysmal subarachnoid hemorrhage patients was conducted. The authors assessed morphometric parameters, packing density, first coil volume packing density (1st VPD) and recanalization rate on digital subtraction angiograms (DSA). The effectiveness of initial endovascular treatment was visually determined using the modified Raymond–Roy classification directly after the embolization and in a 6- and 12-month follow-up DSA. In the next step, a comparison between porous media CFD analyses and our statistical results was performed. A geometry used during numerical simulations based on a patient-specific anatomy, where the aneurysm dome was modelled as a separate, porous domain. To evaluate hemodynamic changes, CFD was utilized for a control case (without any porosity) and for a wide range of porosities that resembled 1–30% of VPD. Numerical analyses were performed in Ansys CFX solver. Results: A multivariate analysis showed that 1st VPD affected the late recanalization rate (p < 0.001). Its value was significantly greater in all patients without recanalization (p < 0.001). Receiver operating characteristic curves governed by the univariate analysis showed that the model for late recanalization prediction based on 1st VPD (AUC 0.94 (95%CI: 0.86–1.00) is the most important predictor of late recanalization (p < 0.001). A cut-off point of 10.56% (sensitivity—0.722; specificity—0.979) was confirmed as optimal in a computational fluid dynamics analysis. The CFD results indicate that pressure at the aneurysm wall and residual flow volume (blood volume with mean fluid velocity > 0.01 m/s) within the aneurysmal dome tended to asymptotically decrease when VPD exceeded 10%. Conclusions: High 1st VPD decreases the late recanalization rate in ruptured intracranial aneurysms treated with coil embolization (according to our statistical results > 10.56%). We present an easy intraoperatively calculable predictor which has the potential to be used in clinical practice as a tip to improve clinical outcomes.

Abstract OBJECTIVE To compare the risk of shunt-dependent hydrocephalus after treatment of ruptured intracranial aneurysms by clipping versus coiling. METHODS We analyzed 596 patients prospectively added to our database from July of 1999 to November of 2005 concerning the risk of shunt dependency after clipping versus coiling. Factors analyzed included age; sex; Hunt and Hess grade; Fisher grade; acute hydrocephalus; intraventricular hemorrhage; angiographic vasospasm; and number, size, and location of aneurysms. In addition, a meta-analysis of available data from the literature was performed identifying four studies with quantitative data on the frequency of clip, coil, and shunt dependency. RESULTS The institutional series revealed Hunt and Hess grade, Fisher grade, acute hydrocephalus, intraventricular hemorrhage, and angiographic vasospasm as significant (P &lt; 0.05) risk factors for shunt dependency after a univariate analysis. In a multivariate logistic regression analysis, we isolated intraventricular hemorrhage, acute hydrocephalus, and angiographic vasospasm as independent, significant risk factors for shunt dependency. The meta-analysis, including the current data, revealed a significantly higher risk for shunt dependency after coiling than after clipping (P = 0.01). CONCLUSION Clipping of a ruptured aneurysm may be associated with a lower risk for developing shunt dependency, possibly by clot removal. This might influence long-term outcome and surgical decision making.

Abstract INTRODUCTION ISAT demonstrated that coiling is effective for aneurysm treatment in subarachnoid hemorrhage (SAH); however, complete occlusion of wide-necked aneurysms frequently requires adjuvants relatively contraindicated in SAH. As such, a limited “dome occlusive” strategy is often pursued in the setting of SAH. We report a single institution series of coiling of acutely ruptured aneurysms followed by delayed flow diversion for definitive, curative occlusion. METHODS A prospectively collected IRB-approved database was screened for patients with aneurysmal SAH who were initially treated by coil embolization followed by planned flow diversion at a single academic medical institution. Peri-procedural outcomes, complications, and angiographic follow-up were analyzed. RESULTS >50 patients underwent both acute coiling followed by delayed, planned flow diversion. Average aneurysm size on initial presentation was 9.5 mm. Common aneurysm locations included Pcomm (36%), Acomm (30%), MCA (10%), ACA (10%), and vertebral (5%). Dome occlusion was achieved in all cases following initial coiling. Second-stage implantation of a flow diverting stent was achieved in 49/50 cases (98%). Follow-up angiography was available for 33/50 patients (66%), with mean follow-up of 11 months. 27 patients (82%) had complete angiographic occlusion at last follow up. All patients with residual filling at follow-up still had dome occlusion. There were no mortalities (0%). Major complication rate for stage I coiling was 2% (1 patient with intra-procedural aneurysm re-rupture causing increase in a previous ICH). Major complication rate for stage 2 flow diversion was 2% (1 patient with ischemic stroke following noncompliance with dual antiplatelet regimen). Minor complications occurred in 2 additional patients (4%) with transient neurological deficits. CONCLUSION Staged endovascular treatment of ruptured intracranial aneurysms with acute dome-occlusive coil embolization followed by delayed flow diversion is a safe and effective treatment strategy.

OBJECT Intraprocedural rerupture (IPR) of intracranial aneurysms during coil embolization is associated with significant periprocedural disability and death. However, whether this morbidity and mortality are secondary to an increased risk of vasospasm and hydrocephalus is unknown. The authors undertook this study to determine the in-hospital and long-term neurological outcomes for patients with aneurysmal subarachnoid hemorrhage (SAH) treated with coil embolization who suffer aneurysm rerupture during treatment. METHODS The records of 156 patients admitted with SAH from previously untreated, ruptured, intracranial aneurysms and treated with endovascular coiling between January 2007 and January 2014 were retrospectively reviewed. Twelve patients (7.7%) experienced IPR during coil embolization. RESULTS Compared with the cohort of patients with uncomplicated coil embolization procedures, patients with aneurysm rerupture were more likely to require external ventricular drain (EVD) placement (91.7% vs 58.3%, p = 0.02) and postprocedural EVD placement (36.4% vs 7.1%, p = 0.01), to undergo permanent ventriculoperitoneal shunt placement (50.0% vs 18.8%, p = 0.02), to develop symptomatic vasospasm (50.0% vs 18.1%, p = 0.02), and to have longer lengths of hospital stay (median 21.5 days vs 15.0 days, p = 0.04). Admission Hunt and Hess, modified Fisher, and Barrow Neurological Institute grades did not differ between the 2 cohorts, nor did long-term functional neurological outcomes as assessed by the modified Rankin Scale. CONCLUSIONS Intraprocedural rerupture during coil embolization for ruptured intracranial aneurysms is associated with an increased risk of symptomatic vasospasm and need for temporary and permanent cerebrospinal fluid diversion for hydrocephalus.
