BackgroundThe Japanese Registry of NeuroEndovascular Therapy 2 (JR-NET2) and 3 (JR-NET3) were nationwide surveys that evaluated clinical outcomes after neuroendovascular therapy in Japan. The aim of this study was to compare the prevalence and risk factors of complications of intracranial tumor embolization between JR-NET2 and JR-NET3.MethodsA total of 1018 and 1545 consecutive patients with intracranial tumors treated with embolization were enrolled in JR-NET2 and JR-NET3, respectively. The prevalence of complications in intracranial tumor embolization and related risk factors were compared between JR-NET2 and JR-NET3.ResultsThe prevalence of complications in JR-NET3 (3.69%) was significantly higher than that in JR-NET2 (1.48%) (p=0.002). The multivariate analysis in JR-NET2 showed that embolization for tumors other than meningioma was the only significant risk factor for complication (odds ratio [OR], 3.88; 95% confidence interval [CI], 1.13-12.10; p=0.032), and that in JR-NET3 revealed that embolization for feeders other than external carotid artery (ECA) (OR, 3.56; 95% CI, 2.03-6.25; p<0.001) and use of liquid materials (OR, 2.65; 95% CI, 1.50-4.68; p<0.001) were significant risks for complications. The frequency of embolization for feeders other than ECA in JR-NET3 (15.3%) was significantly higher than that in JR-NET2 (9.2%) (p<0.001). Also, there was a significant difference in the frequency of use of liquid materials between JR-NET2 (21.2%) and JR-NET3 (41.2%) (p<0.001).ConclusionsEmbolization for feeders other than ECA and use of liquid materials could increase the complication rate in intracranial tumor embolization.

脳動脈瘤に対する脳血管内コイリング治療後や開頭ネック・クリッピング手術後のネックやドームの解剖学的形態の描出に、Silent MRAとfast spin-echo(FSE)MR cisternography(MRC)の3D融合画像を新しく考案した。これまでのtime-of-flight(TOF)MRAでは、金属による磁化率アーチファクトやRF遮断効果の影響で、コイルやクリップ近傍のネック形態を描出することは困難であった。Silent MRAでは、金属による磁化率アーチファクトの影響を受け難く、コイリング治療後やクリッピング手術後のネックや母血管の形態が良好に描出された。また、FSE MRCでは、コイリング治療後のドームやネック部の形態、クリッピング処理されたネックの形態が詳細に描出された。Silent MRAとFSE MRC、それぞれの3D画像を重量描画する、Silent MRAとFSE MRCの3D融合画像を、コイリング治療後の15例、クリッピング手術後の19例に応用した結果、脳動脈瘤治療後のネック・ドームの画像評価に有用であった。本稿では、Silent MRAとFSE MRCの3D融合画像の作成技術と臨床応用につき報告する。(著者抄録)

当院でIC-PC AN(未破裂内頸動脈後交通動脈分岐部瘤)に対し初回塞栓術を行った42例を対象に、後交通動脈(Pcom A)の発達程度に基づきfetal type(F群)17例、adult type(A群)9例、hypoplastic type(H群)16例に分け、検討した。その結果、再発率はF群18%、A群11%、H群19%で、再治療率はF群6%、A群0%、H群13%であった。再発に関わる因子を検討すると、単変量解析では7mm以上の最大径と高難度瘤で有意差を認めたが、Pcom Aの有無では有意差を認められなかった。今回の検討から、Pcom Aが描出される症例でPcom Aの温存を重視してコイル塞栓術を行っても再発や再治療には影響しないことが判明した。

Visualization of Aneurysmal Neck and Dome after Coiling with 3D Multifusion Imaging of Silent MRA and FSE-MR Cisternography. International journal

T Satoh, T Hishikawa, M Hiramatsu, K Sugiu, I Date

AJNR. American journal of neuroradiology 40 ( 5 ) 802 - 807 2019.5

Language：English Publishing type：Research paper (scientific journal)

BACKGROUND AND PURPOSE: Our aim was to visualize the precise configuration of the aneurysmal neck and dome with/without remnants combined with a coiled dome after coiling treatment for cerebral aneurysms. We developed 3D multifusion imaging of silent MRA and FSE-MR cisternography. MATERIALS AND METHODS: We examined 12 patients with 3D multifusion imaging by composing 3D images reconstructed from TOF-MRA, silent MRA, and FSE-MR cisternography. The influence of magnetic susceptibility artifacts caused by metal materials affecting the configuration of the aneurysmal complex with coiling was assessed in a single 3D image. RESULTS: In all cases, TOF-MRA failed to depict the aneurysmal neck complex precisely due to metal artifacts, whereas silent MRA delineated the neck and parent arteries at the coiled regions without serious metal artifacts. FSE-MR cisternography depicted the shape of the coiled aneurysmal dome and parent artery complex together with the brain parenchyma. With the 3D multifusion images of silent MRA and FSE-MR cisternography, the morphologic status of the coiled neck and parent arteries was clearly visualized with the shape of the dome in a single 3D image. CONCLUSIONS: Silent MRA is a non-contrast-enhanced form of MRA. It depicts the coiled neck complex without serious metal artifacts. FSE-MR cisternography can delineate the shape of the coiled dome. In this small feasibility study, 3D multifusion imaging of silent MRA and FSE-MR cisternography allowed good visualization of key features of coiled aneurysms. This technique may be useful in the follow-up of coiled aneurysms.

Previous randomized clinical trials have revealed significant benefit of the endovascular thrombectomy for the patients with acute ischemic stroke. In this short communication, I would like to introduce the history of endovascular treatment for acute ischemic stroke in Japan, and give a positive message to the neurologists who might contribute to the treatment for acute ischemic stroke.

Embolization for intracranial tumor is performed as a standard endovascular treatment. A retrospective, multicenter, observational study was conducted to clarify the nature, frequency, and risk factors of complications in intracranial tumor embolization. Patients were derived from the Japanese Registry of NeuroEndovascular Therapy (JR-NET3) using data taken from January 2010 through December 2014 in Japan. A total of 40,169 patients were enrolled in JR-NET3, of which, 1,545 patients (3.85%) with intracranial tumors underwent embolization. The primary end point was the proportion of patients with a modified Rankin scale (mRS) score of 0-2 (independency) at 30 days after embolization. The secondary end point was the occurrence of complications related to the procedures. The risk factors of the development of complications were analyzed. The proportion of patients with mRS scores <= 2 at 30 days after procedure was 89.5%. Complications occurred in 57 of the 1544 patients (3.7%). Multivariate analysis showed that target vessels other than external carotid artery (ECA) (OR, 3.56; 95% CI, 2.03-6.25; P < 0.001) and use of liquid material (OR, 2.65; 95% CI, 1.50-4.68; P < 0.001) were significantly associated with the development of complications. In JR-NET3, the primary end point was 89.5%, and the procedure-related complication rate was 3.7%. Embolization from other than ECA was significant risk factor of the complications. In addition, increasing usage of liquid embolic material worsened the risk of complications.

OBJECTIVECerebral hyperperfusion syndrome (CHS) is a serious complication after carotid artery stenting (CAS). Staged angioplasty (SAP)-i.e., angioplasty followed by delayed CAS-has been reported as a potential CHS-avoiding procedure. The purpose of this study was to clarify the effectiveness of SAP in avoiding CHS after carotid revascularization for patients at high risk for this complication.METHODSThe authors retrospectively studied cases involving patients at high risk for CHS from 44 Japanese centers who were scheduled for SAP, regular CAS, angioplasty, or staged procedures other than SAP between October 2007 and March 2014. They investigated the rate of CHS in the population scheduled for SAP or regular CAS, and for safety analysis, the composite rate of transient ischemic attack (TIA) and ischemic stroke in the population eventually receiving SAP or regular CAS.RESULTSData from a total of 525 patients (532 lesions, mean age 72.5 ± 7.5 years, 74 women ) were analyzed. Scheduled procedures included SAP for 113 lesions and regular CAS for 419 lesions. The rate of CHS was lower in the SAP group than in the regular CAS group (4.4% vs 10.5%, p = 0.047). Multivariate analysis showed that SAP was negatively related to CHS (OR 0.315; 95% CI 0.120-0.828). In the population eventually receiving SAP (102 lesions) or regular CAS (428 lesions), the composite rate of TIA and ischemic stroke was comparable between the SAP group and the regular CAS group (9.8% vs 9.3%).CONCLUSIONSSAP may be an effective and safe carotid revascularization procedure to avoid CHS.
