In a few cases, endovascular treatment of cerebral aneurysms may be challenging due to difficulty in obtaining a proper working view. In this report of 6 cases, we described the advantage of using a distal intracranial catheter (DIC) to achieve better visualization of cerebral aneurysms hidden by a parent artery or its branches. Between September 2017 and January 2021, we treated 390 aneurysms with endovascular techniques. In 6 cases in which it was difficult to obtain a proper working view, the DIC was placed distally close to the aneurysm in order to remove the parent artery projection from the working view and obtain better visualization of the aneurysm. Clinical and procedural outcomes and complications were evaluated. The position of the DIC was above the internal carotid artery siphon in the 6 cases. All aneurysms were successfully embolized. Raymond-Roy class 1 occlusion was achieved in all 4 unruptured aneurysms, while the result was class 2 in the 2 ruptured aneurysms. Placement of the DIC was atraumatic without dissections or significant catheter-induced vasospasm in all patients. Transient dysphasia was seen in 2 cases and transient aphasia in 1. Using this technique, we have found it possible to better visualize the aneurysm sac or neck and thereby treat cases we otherwise would have considered untreatable.</p>","PeriodicalId":19140,"journal":{"name":"Neurointervention","volume":"16 3","pages":"267-274"},"PeriodicalIF":0.0,"publicationDate":"2021-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/e0/2b/neuroint-2021-00269.PMC8561035.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"39490086","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}

A systematic review with meta-analysis was performed using databases. The following descriptors were used for the search: \"SILK\", \"Flow Diverter\", \"Mortality\", and \"Prognosis\".

Therefore, screening for UIA must be tailored to specific populations in order to balance the prevalence and risk of UIA, cost-effectiveness of screening tests, and the availability of effective and safe treatment. Of these, estimating the prevalence and risk factor of UIA by epidemiological study is methodologically challenging, requiring an optimal cohort for prospective studies with a large amount of data. In the last issue, Kim and colleagues evaluated the prevalence (3.77%) and risk factors (female predominance and hypertension) of UIAs from healthy individuals who underwent brain magnetic resonance angiography using 3T magnetic resonance imaging as part of a routine health examination. There have been several other studies evaluating the prevalence and risk factors of UIA in the literature. The studies were variable with regards to the population studied, indication for imaging, and method of detection (Table 1). The reported prevalence of UIA in the literature ranged 1.8–8.8%, and was 3.2% according to combined results from a systematic review and meta-analyses, which was also similar to the result (3.77%) from Kim et al. In evaluating the risk factors of UIA, it was more common in women, older age, smokers, patients with hypertension, autosomal dominant polycystic kidney disease (ADPKD), or in individuals with family history of intracranial aneurysm of SAH. Consequently, Korean Clinical Practice Guidelines for UIA currently recommended that UIA should be screened according to the following three categories; 1) patients who have 2 or more first-degree relatives with an intracranial aneurysm; 2) patients with ADPKD; and 3) regular screening tests for new aneurysms for patients previously treated with aneurysmal SAH. Although the current guidelines do not support widespread screening for intracranial aneurysms in the general population, additional screening may be considered in patients with other genetic or medical conditions associated with intracranial aneurysms. Recently, according to the data from Korean National Health Insurance Service (NHIS), the number of treatments for UIA has increased because of the increased detection rate as well as increase in number of hospitals capable Correspondence to: Bum-soo Kim, MD Department of Radiology, Seoul St. Mary’s Hospital, College of Medicine, The Catholic University of Korea, 222 Banpo-daero, Seocho-gu, Seoul 06591, Korea Tel: +82-2-2258-9639 Fax: +82-2-599-6771 E-mail: bkim.neurorad@gmail.com","PeriodicalId":19140,"journal":{"name":"Neurointervention","volume":"16 3","pages":"201-203"},"PeriodicalIF":0.0,"publicationDate":"2021-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/8b/9d/neuroint-2021-00451.PMC8561037.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"39551049","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}
