Method: Search for relevant studies on PubMed/Medline until November 7, 2023, and further screen the bibliographies of relevant studies to ensure comprehensive search. According to the PRISMA guidelines, manuscripts were selected to provide local hemodynamic information on AVM arterial feeders and drainage veins. Result: A total of 13 studies were included in the final analysis. The diameter of the supplying artery (y = 0.002x + 2.24, R2 = 0.99) and flow velocity (y = 0.09x + 54.55, R2 = 0.92) had a positive linear relationship with cerebral blood flow. The pressure difference through the small AVM nidus was higher than that in the large AVM, with values of (y = -12.23x + 101.39, R2 = 0.96). There was a negative linear correlation between the sessions of AVM embolization and blood flow (1 session: y = -150.7x + 564.97, R2 = 0.98 and 4 sessions: y = -118.81x + 750.07, R2 = 0.99). There was a positive linear relationship between the increase in arterial pressure, peri-AVM parenchymal perfusion, and the percentage of occlusion in the medium-sized AVMs. However, this correlation was a nonlinear relationship between elevated arterial pressure, peri-AVM parenchymal perfusion, and the percentage of large AVM occlusion. Conclusion: The hemodynamic changes of AVM (in the feeding arteries, compartments of AVM, and draining veins) follow a linear relationship. The impact of embolization on hemodynamics in medium and small AVMs follows a linear relationship. The impact of embolization of large AVMs on hemodynamics follows a nonlinear relationship.","PeriodicalId":47358,"journal":{"name":"Neuroradiology Journal","volume":" ","pages":"19714009241303056"},"PeriodicalIF":1.3,"publicationDate":"2024-11-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11590089/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142717455","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}

Clinically, it is characterized by congenital blindness and progressive sensorineural hearing loss during adolescence. We present images of a 3 year old child with ND and normal hearing demonstrating bilateral cochlear enhancement on brain MRI, a finding which has not been previously reported. ND mouse models show progressive degeneration of the endolymph-producing stria vascularis (SV); we hypothesize that these changes allow gadolinium leakage into the endolymph. Our images indicate that cochlear enhancement precedes changes in hearing and suggest that temporal bone/internal auditory canal MR imaging should be considered in the evaluation of ND. Future studies are needed to characterize the temporal evolution of this cochlear enhancement and how it corresponds with hearing loss. Mouse models suggest that it may be a transient phenomenon and diminish as the SV degenerates further. As ND gene therapy trials approach clinical use, cochlear enhancement could aid candidate selection and provide insight into treatment effect.","PeriodicalId":47358,"journal":{"name":"Neuroradiology Journal","volume":" ","pages":"19714009241303096"},"PeriodicalIF":1.3,"publicationDate":"2024-11-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11586931/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142711512","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}

One potential concern during stenting is impairment of venous outflow in the Labbé vein, which usually drains in close proximity to the culprit transverse sinus stenosis. Methods: We propose a technique which can counteract venous outflow impairment, consisting of temporary balloon protection of the Labbé vein during stent deployment. Results: We illustrate the use of this technique in a case of IIH with intrinsic dural sinus stenosis induced by a large arachnoid granulation situated close to the insertion of the Labbé vein. The stent was deployed under temporary balloon inflation in order to deflect the arachnoid granulation away from the vein ostium. Conclusions: In selected cases of intrinsic stenosis, temporary balloon protection can be used to avoid Labbé vein flow impairment during venous sinus stenting.","PeriodicalId":47358,"journal":{"name":"Neuroradiology Journal","volume":" ","pages":"19714009241303148"},"PeriodicalIF":1.3,"publicationDate":"2024-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11584999/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142692940","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}

In this study, we aimed to introduce our coaxial balloon technique using a balloon-guiding catheter (BCG), angioplasty catheter, and aspiration catheter sequentially to prevent thrombus migration to a new vascular territory. We used this technique for six patients with CTO. Technical success with good revascularization of the CTO was achieved in all six patients (100%) without neurological complications, including one and five cases of modified Thrombolysis in Cerebral Infarction 2b and 3, respectively. The median duration of the procedure was 61 (interquartile range, 52-90) min. The mean National Institutes of Health Stroke Scale score at discharge was 3.5 (2-8), with favorable clinical outcomes at 90 days for three of six patients (50%). The coaxial balloon technique for CTO is safe and effective for revascularization in patients with acute ischemic stroke. Thrombectomy before proximal stenting was associated with shorter reperfusion times and better clinical outcomes. Therefore, this approach is recommended for tandem occlusions requiring stent angioplasty.","PeriodicalId":47358,"journal":{"name":"Neuroradiology Journal","volume":" ","pages":"19714009241303137"},"PeriodicalIF":1.3,"publicationDate":"2024-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11584997/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142693098","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}

In last years, several observational studies have suggested noninferiority or superiority of A Direct Aspiration first-Pass Technique (ADAPT) technique to achieve better reperfusion in comparison to stent retriever. While ASA/AHA 2018 guidelines recommend that patients with AIS should receive Mechanical Thrombectomy with a stent retriever, last European Stroke Organization guidelines report no evidence that stent retriever compared with contact aspiration could improve reperfusion rate. ADAPT is based on aspiration alone as the primary mechanism of thrombectomy and, if initially unsuccessful, then incorporating adjunctive alternatives. ADAPT improvement is also related to last generation of aspiration catheters. The purpose of this review is to report ADAPT principles, technique, efficacy, and safety as first-line treatment for acute ischemic stroke with the latest generation of reperfusion devices.","PeriodicalId":47358,"journal":{"name":"Neuroradiology Journal","volume":" ","pages":"19714009241303063"},"PeriodicalIF":1.3,"publicationDate":"2024-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11577322/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142677308","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}
