[Ab] Abstract:OBJECTIVE: Vessel wall magnetic resonance imaging (MRI) has been suggested as a potential in vivo method to detect inflammation of aneurysm wall and identify unruptured intracranial aneurysm (UIA) with high rupture risk. This study aims to investigate the correlation between aneurysm wall enhancement (AWE) on vessel wall MRI and rupture-related morphological parameters in patients with multiple UIAs. METHODS: Clinical data and VW-MRI images were reviewed in 14 patients with 30 multiple UIAs. The AWE was defined as enhancement of the aneurysm wall in post-contrast vessel wall images using the pre-contrast image as reference. Morphological parameters, including aneurysm size, aspect ratio (AR), size ratio (SR), bottleneck factor (BNF), height-to-width ratio (HW), nonsphericity index (NSI) and inflow angle (IFA) were measured using 3-dimensional rotation angiography. Univariate and multivariate analysis were performed to reveal the correlation between morphological parameters and the presence of AWE. RESULTS: Sixteen of the 30 multiple UIAs presented with AWE on vessel wall MRI images. UIAs with AWE were proven to have a significantly larger size (P=0.001), AR (P=0.047), SR (P=0.003), BNF (P=0.007) and NSI (P=0.007) in univariate analysis. Further multivariate logistic regression showed that aneurysm size [odds ratio (OR)=3.54; 95% confidence interval (CI)=1.10-11.35; P=0.033] and NSI (OR=3.53; 95% CI=1.06-11.80; P=0.040) were independently associated with the presence of AWE in multiple UIAs. CONCLUSION: The presence of AWE on vessel wall MRI was significantly correlated with conventional morphological rupture risk factors in patients with multiple UIAs, which might indicate AWE as a potential radiological predictor for UIAs with high rupture risk.

[Ab] Abstract:BACKGROUND AND PURPOSE: The WEB is an innovative flow disruption device for cerebral aneurysm embolization with rapidly expanding indications. Our purpose was to evaluate the diagnostic performance of CTA at 1-year follow-up of aneurysms treated with the WEB. MATERIALS AND METHODS: Between April 2014 and May 2016, the study prospectively included patients treated with the WEB at our institution, and followed up within 24hours by CTA and at 1 year by CTA, TOF MRA and DSA. The diagnostic quality of imaging data was assessed based on the confidence index, artifacts, and WEB shape depiction. The imaging diagnostic performance was assessed using 3 criteria at 1 year: aneurysm occlusion status and worsening, and WEB shape compression. Interobserver and intermodality agreement was determined by calculating κ values. RESULTS: The study ultimately included 16 patients (9 women, mean age 53 ± 7.6 years). CTA quality confidence was scored as 2/2, artifacts 0.4/2 and WEB shape depiction 1.9/2, superior to TOF MRA for the latter two criteria. Aneurysm occlusion was adequate in 93.7% of patients, with CTA showing excellent interobserver reproducibility and agreement with DSA on a 4-grade scale (κ = 1.00), while TOF MRA yielded good reproducibility (κ = 0.76) and agreement with DSA (κ = 0.69). CTA also identify aneurysm occlusion worsening (43.7%) and WEB compression (81.2%) in excellent agreement with DSA (κ = 0.85 and 1.00). CONCLUSIONS: CTA is a reproducible and reliable technique for the follow-up of aneurysms treated with the WEB device.

[Ti] Title:Clinical importance of the anterior choroidal artery: a review of the literature.

[Ab] Abstract:The anterior choroidal artery (AChA) is a critical artery in brain physiology and function. The AChA is involved in many diseases, including aneurysm, brain infarct, Moyamoya disease (MMD), brain tumor, arteriovenous malformation (AVM), etc. The AChA is vulnerable to damage during the treatment of these diseases and is thus a very important vessel. However, a comprehensive systematic review of the importance of the AChA is currently lacking. In this study, we used the PUBMED database to perform a literature review of the AChA to increase our understanding of its role in neurophysiology. Although the AChA is a small thin artery, it supplies an extremely important region of the brain. The AChA consists of cisternal and plexal segments, and the point of entry into the choroidal plexus is known as the plexal point. During treatment for aneurysms, tumors, AVM or AVF, the AChA cisternal segments should be preserved as a pathway to prevent the infarction of the AChA target region in the brain. In MMD, a dilated AChA provides collateral flow for posterior circulation. In brain infarcts, rapid treatment is necessary to prevent brain damage. In Parkinson disease (PD), the role of the AChA is unclear. In trauma, the AChA can tear and result in intracranial hematoma. In addition, both chronic and non-chronic branch vessel occlusions in the AChA are clinically silent and should not deter aneurysm treatment with flow diversion. Based on the data available, the AChA is a highly essential vessel.

[Ab] Abstract:BACKGROUND: Optical coherence tomography (OCT) is a high-resolution, intra-vascular diagnostic technique widely used for the characterization of vascular pathologies and optimization of stent implantation during percutaneous coronary intervention. OCT was used to investigate the in vivo vascular response to a new phosphorylcholine surface modified flow diverter (sPED). METHODS: In an in vivo rabbit aneurysmal model, we used two different types of flow diverters (classic Pipeline - cPED; and sPED) with or without dual antiplatelet therapy (four groups, n=10 per group). OCT cross-sectional area measurements were compared with histology in all animals. Neointimal hyperplasia (NIH) ratio was compared between OCT and histology at five different levels for each stent. The severity of NIH was also compared between the different stents, antiplatelet protocols, and vessel locations. RESULTS: OCT was used to calculate in-stent hyperplasia in 227 different locations corresponding to histology sections. OCT measurement strongly correlated with gold standard histology (r =0.83; slope=0.988; P<0.0001). sPED had significantly less in-stent NIH than non-treated flow diverters (mean percent of lumen reduction 5.7% for sPED versus 8.9% for cPED; P<0.0001). The NIH ratio was slightly higher with dual antiplatelet therapy (DAPT) (NIH ratio=7.9% with DAPT versus 6.8% without DAPT; P<0.05). Complete and near complete occlusion rates of the aneurysms were not different with the cPED or sPED. CONCLUSION: OCT is a promising technique for immediate and long-term evaluation of flow diverter stent treatments. In an animal model, phosphorylcholine surface modified flow diverters induces less NIH after stent implant without reducing aneurysm occlusion rates.

[Ab] Abstract:BACKGROUND: Intracranial aneurysms more often occur in the same arterial territory within families. Several aneurysm locations are associated with specific circle of Willis variations. We investigated whether the same circle of Willis variations are more likely to occur in first-degree relatives than in unrelated individuals. METHODS: We assessed four circle of Willis variations (classical, A1-asymmetry, incomplete posterior communicating artery and fetal circulation) in two independent groups of families with familial aneurysms and ≥2 first-degree relatives with circle of Willis imaging on MRA/CTA. In each (index) family we determined the proportion of first-degree relatives with the same circle of Willis variation as the proband and compared it to the proportion of first-degree relatives of a randomly selected unrelated (comparison) family who had the same circle of Willis variation as the index family's proband. Concordance in index families and comparison families was compared with a conditional logistic events/trials model. The analysis was simulated 1001 times; we report the median concordances, odds ratios (ORs), and 95% confidence intervals (95%CI). The groups were analysed separately and together by meta-analysis. RESULTS: We found a higher overall concordance in circle of Willis configuration in index families than in comparison families (meta-analysis, 244 families: OR 2.2, 95%CI 1.6-3.0) mostly attributable to a higher concordance in incomplete posterior communicating artery (meta-analysis: OR 2.8, 95%CI 1.8-4.3). No association was found for the other three circle of Willis variations. CONCLUSIONS: In two independent groups of families with familial aneurysms, the incomplete PcomA variation occurred more often within than between families suggesting heritability of this circle of Willis variation. Further studies should investigate genetic variants associated with circle of Willis formation.

[Ab] Abstract:PURPOSE: Contrast-induced acute kidney injury (CI-AKI) is associated with poor outcomes after percutaneous coronary intervention. However, CI-AKI has rarely been evaluated within the neurovascular field. The aim of this study was to investigate the incidence and clinical implication of CI-AKI after coil embolization in patients with an aneurysmal subarachnoid hemorrhage (aSAH). MATERIALS AND METHODS: Between January 2005 and March 2016, 192 patients who underwent coil embolization were enrolled in this study. CI-AKI was defined as an increase from baseline serum creatinine concentration of >25% or >0.5 mg/dL within 72 hours after coil embolization. A poor clinical outcome was defined as a score of ≥3 on the modified Rankin Scale at one-year post-treatment. RESULTS: A total of 16 patients (8.3%) died as a result of medical problems within one year. CI-AKI was identified in 14 patients (7.3%). Prominent risk factors for one-year mortality included CI-AKI [odds ratio (OR): 16.856; 95% confidence interval (CI): 3.437-82.664] and an initial Glasgow Coma Scale (GCS) score ≤8 (OR: 5.565; 95% CI: 1.703-18.184). A poor clinical outcome was associated with old age (≥65 years) (OR: 7.921; 95% CI: 2.977-21.076), CI-AKI (OR: 11.281; 95% CI: 2.138-59.525), an initial GCS score ≤8 (OR 31.02; 95% CI, 10.669-90.187), and a ruptured aneurysm (p=0.016, OR: 4.278) in posterior circulation. CONCLUSION: CI-AKI seems to be an independent predictor of the overall outcomes of aSAH after endovascular treatment.

[Ab] Abstract:The Pipeline embolization device (PED), a type of flow diverter, has become an appealing alternative treatment option for large or giant and wide-necked intracranial aneurysms. Carotid cavernous fistula (CCF) resulting from delayed aneurysmal rupture is a rare complication of PED placement with unknown pathophysiology. Here, we describe a case of CCF resulting from aneurysmal rupture following PED placement, and present the details of treatment by transvenous coil embolization. An 81-year-old woman was referred to our hospital for treatment of an 18.0 × 10.3 mm intracranial aneurysm located in the cavernous segment of the left internal carotid artery, noted during an examination of her diplopia. Endovascular treatment was conducted by positioning a single PED (4.75 × 25 mm) across the neck of the aneurysm. The postoperative course was uneventful, and the patient was discharged 8 days post procedure. On post-procedure day 10, her left oculomotor nerve palsy had worsened and she had developed left abducens nerve palsy, left exophthalmos, and left chemosis. Angiography demonstrated left direct CCF because of rupture of the aneurysm that had been treated with PED. Transvenous coil embolization was performed on post-procedure day 11 to treat the CCF, and complete resolution of the CCF and significant thrombus formation within the aneurysm sac were confirmed 11 days after the second procedure. Our angiographic results suggest that the aneurysmal rupture was caused by aneurysmal volume expansion associated with PED-induced thrombosis. Transvenous coil embolization for the treatment of CCF following PED placement constitutes a new challenge.

[Ti] Title:Accuracy of detecting enlargement of aneurysms using different MRI modalities and measurement protocols.

[Ab] Abstract:OBJECTIVE Aneurysm growth is considered predictive of future rupture of intracranial aneurysms. However, how accurately neuroradiologists can reliably detect incremental aneurysm growth using clinical MRI is still unknown. The purpose of this study was to assess the agreement rate of detecting aneurysm enlargement employing generally used MRI modalities. METHODS Three silicone flow phantom models, each with 8 aneurysms of various sizes at different sites, were used in this study. The aneurysm models were identical except for an incremental increase in the sizes of the 8 aneurysms, which ranged from 0.4 mm to 2 mm. The phantoms were imaged on 1.5-T and 3-T MRI units with both time-of-flight (TOF) and contrast-enhanced MR angiography. Three independent expert neuroradiologists measured the aneurysms in a blinded manner using different measurement approaches. The individual and agreement detection rates of aneurysm enlargement among the 3 experts were calculated. RESULTS The mean detection rate of any increase in any aneurysmal dimension was 95.7%. The detection rates of the 3 observers (observers A, B, and C) were 98.0%, 96.6%, and 92.7%, respectively (p = 0.22). The detection rates of each MRI modality were 91.3% using 1.5-T TOF, 97.2% using 1.5-T with Gd, 95.8% using 3.0-T TOF, and 97.2% using 3.0-T with Gd (p = 0.31). On the other hand, the mean detection rate for aneurysm enlargement was 54.8%. Specifically, the detection rates of observers A, B, and C were 49.0%, 46.1%, and 66.7%, respectively (p = 0.009). As the incremental enlargement value increased, the detection rate for aneurysm enlargement increased. The use of 1.5-T Gd improved the detection rate for small incremental enlargement (e.g., 0.4-1 mm) of the aneurysm (p = 0.04). The location of the aneurysm also affected the detection rate for aneurysm enlargement (p < 0.0001). CONCLUSIONS The detection rate and interobserver agreement were very high for aneurysm enlargement of 0.4-2 mm. The detection rate for at least 1 increase in any aneurysm dimension did not depend on the choice of MRI modality or measurement protocol. Use of Gd improved the accuracy of measurement. Aneurysm location may influence the accuracy of detecting enlargement.

[Ab] Abstract:PURPOSE: We performed computational fluid dynamics (CFD) for patients with and without paraclinoid internal carotid artery (ICA) aneurysms to evaluate the distribution of vascular biomarkers at the aneurysm initiation sites of the paraclinoid ICA. METHODS: This study included 35 patients who were followed up for aneurysms using 3D time of flight (TOF) magnetic resonance angiography (MRA) and 3D cine phase-contrast MR imaging. Fifteen affected ICAs were included in group A with the 15 unaffected contralateral ICAs in group B. Thirty-three out of 40 paraclinoid ICAs free of aneurysms and arteriosclerotic lesions were included in group C. We deleted the aneurysms in group A based on the 3D TOF MRA dataset. We performed CFD based on MR data set and obtained wall shear stress (WSS), its derivatives, and streamlines. We qualitatively evaluated their distributions at and near the intracranial aneurysm initiation site among three groups. We also calculated and compared the normalized highest (nh-) WSS and nh-spatial WSS gradient (SWSSG) around the paraclinoid ICA among three groups. RESULTS: High WSS and SWSSG distribution were observed at and near the aneurysm initiation site in group A. High WSS and SWSSG were also observed at similar locations in group B and group C. However, nh-WSS and nh-SWSSG were significantly higher in group A than in group C, and nh-SWSSG was significantly higher in group A than in group B. CONCLUSION: Our findings indicated that nh-WSS and nh-SWSSG were good biomarkers for aneurysm initiation in the paraclinoid ICA.

[Ab] Abstract:To analyze the incidence of intracranial unruptured aneurysms in patients with internal carotid artery (ICA) stenosis (≥30%), the characteristics of aneurysms and risk factors in patients with ICA stenosis and intracranial aneurysm. Clinical data of patients receiving digital subtraction angiography (DSA) at Peking University Third Hospital between January 2012 and June 2015 were retrospectively reviewed to identify patients with ICA stenosis and unruptured intracranial aneurysm. Among 247 patients with ICA stenosis, 16 patients (6.5%) with intracranial unruptured aneurysms were found including 7 females and 9 males with age from 47 to 83 years old. The severity of ICA stenosis in aneurysm group was (85.3±13.2)%, whereas it was (77.7±17.9)% in non-aneurysm group. The incidence of aneurysms in male patients with ICA stenosis was 4.5%(9/202), and 15.6%(7/45) in female patients ( 0.05). The incidence of aneurysms in patients with only in cervical segment (C1 segment) of ICA was 4.4%(10/226), whereas that of other segment was 28.6%(6/21) ( 0.05). Logistic multivariate regression analysis showed that gender and stenosis location were independent risk factors of aneurysms in patients with ICA stenosis. In patients with ICA stenosis, the incidence of aneurysm is much higher than that in general population. Intracranial aneurysms are more likely to occur in women and patients with ICA stenosis other than C1 segment.
