Five cases were treated with balloon remodeling for aneurysmal subarachnoid hemorrhage, 2 of which were additionally treated with angioplasty due to post-bleeding vasospasm. All patients had their aneurysm located on parent vessels with a diameter smaller than 2 mm. Complete occlusion was noted in all aneurysms, and the patients had no short-term complications attributed to the catheterization. Additionally, we confirm the previously reported smooth navigation of the balloon through vessels with tortuous anatomy without catheter-induced vasospasm. Based on our experience, the SMB can be a safe and efficient device for applying the balloon remodeling technique for distally located wide-neck aneurysms and distal balloon angioplasty.","PeriodicalId":19140,"journal":{"name":"Neurointervention","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86013412","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Materials and Methods The current study reviewed any aggravation history of myelopathy symptoms, including walking difficulty, after consuming taurine-rich foods among 133 consecutive patients with a SAVS from a prospective institutional database from June 2013 to February 2021. The type of taurine-rich foods, demographic data, arteriovenous shunt level, and follow-up periods were obtained. For the controlled taurine challenge test, Bacchus® (Dong-A Pharmaceutical, Seoul, Korea), a taurine-rich drink, was given to patients who fulfilled test criteria of recovered VCM (pain-sensory-motor-sphincter scale ≥2, improvement of spinal cord signal intensity on magnetic resonance imaging, and follow-up >6 months after SAVS treatment) to confirm the disappearance of such aggravation. Results Ten patients had an aggravation history related to food. Webfoot octopus, small octopus, squid, crab, scallop, and taurine-rich energy drink (Bacchus®) were related to such aggravation in patients with VCM. Aggravation appeared about 30 minutes after food intake followed by expressions such as ‘I could not walk and collapsed to the ground’ and usually lasted for about 3 hours, followed by a slow recovery after taking rest. Four patients who met the test criteria underwent the taurine challenge with Bacchus® and revealed no further symptom aggravation, suggesting that taurine did not affect patients after recovery from VCM. Conclusion The association between taurine-rich food and reversible symptom aggravation can appear in patients with VCM and disappear after VCM treatment. Aggravation of venous hypertension in the spinal cord is suggested as a mechanism but further elucidation is needed.","PeriodicalId":19140,"journal":{"name":"Neurointervention","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88801195","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The purpose of this study was to analyze the location of SCAD and its clinical and radiologic patterns in Korean patients. Materials and Methods Patients with SCAD who were evaluated between 2013 and 2018 at a tertiary center in Korea were reviewed. We classified and compared the morphological (aneurysm or steno-occlusion) and presenting (hemorrhage or infarction) patterns according to the lesion locations (anterior circulation [AC] vs. posterior circulation [PC]; intradural [ID] vs. extradural [ED]). Results A total of 166 patients were included in this study. The SCAD most commonly occurred in the PC-ID location (65.1%), followed by AC-ID (13.3%), AC-ED (13.3%), and PC-ED (8.4%). Aneurysm and steno-occlusion patterns were observed in 66.9% and 57.8% of the cases, respectively. The aneurysm pattern was significantly more common in the PC-ID location (78.7%) than in other locations. As for the presenting pattern, cerebral infarction was the most common pattern (39.8%), and intracranial hemorrhage was observed only in the ID location (7.2%). Conclusion In Korean patients, PC-ID, especially ID vertebral artery, was the most common location of SCAD, and most cases were accompanied by an aneurysm. It also suggested that these location trends differ by population or ethnicity.","PeriodicalId":19140,"journal":{"name":"Neurointervention","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77554271","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A stent retriever was deployed to the occluded ACA, and the Acom and proximal ACA segment were significantly straightened. Additionally, we attempted a blind exchange mini-pinning (BEMP) technique, but a subarachnoid hemorrhage (SAH) occurred. Bleeding was almost entirely absorbed 9 days after the procedure, but the SAH recurred at 20 days, and computed tomography angiography revealed a new pseudoaneurysm formation in the Acom.

Atypical ruptured aneurysms, such as blister or dissecting pseudoaneurysms, or those that are unusually distal in the middle cerebral artery (MCA) are challenging to treat with either open or endovascular options, though the pipeline embolization device (PED) has shown promise in multiple case series. We present a case of a ruptured dissecting pseudoaneurysm in the distal MCA (distal M3/proximal M4) prefrontal division in an healthy young patient (<60 years) successfully treated with a PED. The PED was chosen both as the only vessel sparing option in the young patient as well as for its potential as a vessel sacrifice tool if the pseudoaneurysm was felt to be incompletely treated, which in this case was not necessary—though would have leveraged the thrombogenicity of the device as a therapeutic advantage.","PeriodicalId":19140,"journal":{"name":"Neurointervention","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87333931","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The typical description of IIH is as follows: a rare condition of unknown cause, which causes increased intracranial pressure (ICP), and is characterized by symptoms related to increased ICP, especially in young obese females aged 25–45 years. Furthermore, they suggested that a reason for the recent increase in disease incidence in Western society was probably due to the rapid increase in the obese population. In our clinical experience, however, we seldom experience morbid obesity in IIH patients, the trend of which seems a little different from typical reports so far. Although we read a case report published in 2018 by Miyachi et al. with interest several years ago, we failed at the time to pay attention to the body habitus of 2 young Japanese female patients described in the report. One patient was a 27-year-old female (165 cm, 48 kg), and the other was a 17-yearold young female (163 cm, 54 kg). Their body-mass indices were 17.6 kg/m and 20.3 kg/m, respectively. The authors had already mentioned in the report that some other etiology of IIH apart from obesity must be present. This observation suggests the need for having an Asian perspective in the management of medically refractory IIH patients. Since the control of other risk factors of increased ICP is a prerequisite for the long-term durability of a stenting procedure, they emphasized the importance of persistent weight control and management of other risk factors, including obstructive sleep apnea. In reports from Western countries, the importance of weight control has been emphasized for the long-term durability of initially responsive dural sinus stenting. Even bariatric surgery is considered in a refractory situation. However, measures to be taken for Asian patients, who are not overweight or may essentially be underweight, are unclear. Although Miyachi et al. reported a good initial clinical response in both Asian patients, we believe they should follow up these 2 patients in the long term since dural sinus stenting is not a curative treatment for IIH. Since stenting of a collapsed sinus lumen only helps cut the vicious cycle of increased ICP, which is aggravated by secondary venous hypertension caused by extrinsic compression of the sinus, the risk of consecutive sinus lumen colCorrespondence to: Deok Hee Lee, MD, PhD Department of Radiology, Research Institute of Radiology, Asan Medical Center, University of Ulsan College of Medicine, 88 Olympic-ro 43-gil, Songpa-gu, Seoul 05505, Korea Tel: +82-2-3010-5944 Fax: +82-2-476-0090 E-mail: dhlee@amc.seoul.kr","PeriodicalId":19140,"journal":{"name":"Neurointervention","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/b4/7b/neuroint-2021-00507.PMC8891586.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"39907009","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
