This method is a way to observe the aneurysm using the 2 dimensional (2D) DSA data based on the calculations of time to peak (TTP) and time duration (TD) of the contrast agent flow in the blood vessel in order to capture the aneurysm and visualize it using a color system based on a specific index.Results: In this study, the color changes of the DSA data that were processed using open source MATLAB software were found in 24 cases (88.9%) and only 3 cases (11.1%) did not show any color changes. Based on Spearman's correlation test, there was a significant correlation between the size of the high dome, dome-neck ratio, and the aspect ratio (p <0.01) on the color changes of data that were processed using DSA MATLAB software.Conclusion: The modification methods that capture color changes in different blood vessels are expected to be able to assist clinicians in the detection of intracranial aneurysms more quickly and precisely and are also highly dependent on the subjectivity of the observer; this method is a way to help neurosurgeons come up with new approaches for the management of aneurysms. Key Words: Intracranial aneurysm, DSA, MATLAB software, color changes","PeriodicalId":206128,"journal":{"name":"Indonesian Journal of Neurosurgery","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124406331","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}

Cacciotti","doi":"10.15562/IJN.V1I1.2","DOIUrl":"https://doi.org/10.15562/IJN.V1I1.2","url":null,"abstract":"AbstractOBJECT: Incidence of typical trigeminal neuralgia (TN) increases with age and neurologists and neurosurgeons frequently observe patients with this disorder at the age of 65 or more. Microvascular decompression (MVD) of the trigeminal root entry zone in posterior cranial fossa is the only etiological therapy for typical TN with the highest efficacy and durability of all treatments. This procedure is associated with possible risks (cerebellar hematoma, cranial nerve injury, stroke, and death) not seen with the alternative ablative procedures. Thus, the safety of MVD in the elderly remains non definitively demonstrated. This study was conducted to determine whether MVD is a safe and effective treatment in elderly patients with TN in comparison to younger patients.METHODS: In this retrospective study, 25 patients older than 65 (mean age 70.1 ± 3.7 years) and 32 aging <65 (mean age 51.1 ± 6.2 years) underwent MVD by key-hole retrosigmoid approach for Type 1 TN (typical) or Type 2a TN (typical chronicized) from November 2011 to November 2016. A 75 y-o patient had Type 2b TN (atypical) versus 3 nonelderly patients were excluded. Elderly and younger groups were compared in relation to outcome and complication data.RESULTS: At a mean follow-up 23.0 ± 5.5 months, 22 old patients (88%) reported a very good outcome without necessity of any medication for pain, versus 28 (87,5%) of the younger group. Twenty elderly patients with Type 1 TN were compared with 24 younger patients with Type 1 TN, and no significant difference in outcomes was found (p > 0.05). Five elderly patients with Type 2a TN were compared with 8 younger patients with Type 2a TN, and no significant difference in outcomes was noted (p > 0.05). There was one case of CSF leak and one case of cerebellar hematoma both in the younger cohort. Mortality was zero in both groups.CONCLUSIONS: On the basis of our experience and of the international literature, age itself seems not to represent a major contraindication against MVD for TN. Keywords: Elderly, Microvascular Decompression, Retrosigmoid approach, Trigeminal neuralgia, Tic douloureux","PeriodicalId":206128,"journal":{"name":"Indonesian Journal of Neurosurgery","volume":"4 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115683788","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}
