Data were retrieved and recorded in a structured spreadsheet including demographic details, symptoms and comorbidities, endovascular techniques employed and graft types, as well as treatment outcomes including 30-day mortality, 1-, 3-, and 5-year survival, aneurysm resolution percentage, and rates of re-intervention and complications.\u0000 Statistical Analysis Descriptive statistics summarized the demographic and clinical characteristics, presenting them as means for continuous variables and frequencies/percentages for categorical variables.\u0000 Results Of the 15 included patients, 73.3% (11/15) and 26.7% (4/15) were males and females, respectively, with a mean age of 64 years. Imaging revealed diverse anatomical involvement, with MAA in the descending thoracic (6/15), suprarenal and juxtarenal (5/15), infrarenal (3/15), and common iliac arteries (1/15). The 30-day mortality rate was 6.7% (1/15), while 1-, 3-, and 5-year survival rates from time of initial intervention were 57.1% (8/14), 38.5% (5/13), and 30.8% (4/13), respectively, with 1 case only just having undergone 1-month follow-up (performed in July 2023). The average mycotic aneurysm size was 47 mm (range: 19–80 mm), of which 33.3% (5/15) presented with rupture. The average sac size reduction following treatment was 31%, with 5/15 cases demonstrating complete resolution. Four cases required re-intervention due to persistent endoleak, sac re-expansion secondary to delayed endoleak, or stent occlusion. Persistent or recurrent graft infection was observed in 53.3% (8/15) of cases. Two cases required surgical re-intervention for stent occlusion.\u0000 Conclusion Our findings reinforce the role of endovascular interventions in MAA acute management, showcasing immediate survival benefits. Late complications and frequent re-interventions emphasize the importance of vigilant surveillance.","PeriodicalId":507357,"journal":{"name":"The Arab Journal of Interventional Radiology","volume":"130 24","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141656603","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}

In this regard, radiology plays a crucial role, acting as the eyes of physicians. In contrast, interventional radiology serves as its hands, acting as one of the most effective drug delivery systems. Among interventional radiology disciplines, arterial drug delivery through arteries holds paramount importance as organs primarily receive nourishment directly from them. Furthermore, regenerative medicine is a burgeoning field dedicated to repairing diverse body tissues without relying on pharmaceutical drugs. Stem cells, inherent in various parts of our bodies, are vital for tissue regeneration and reconstruction. Depending on the treatment approach, stem cells can be sourced from the patient's body (autologous) or another individual (allogeneic). There exist various types of stem cells across species, with regenerative properties observed in animals and even plants. However, targeted cell therapy is preferred over systematic injections throughout the body for better efficacy. This article aims to familiarize interventionalists with stem cells and provide them with a clear and helpful explanation of their functions, mechanisms of action, different sources, and other relevant aspects. This will help them select the most appropriate cells for their therapeutic purposes. By comprehensively understanding the significance of stem cells in interventional radiology, we can implement optimal methodologies to address diverse medical conditions efficiently.","PeriodicalId":507357,"journal":{"name":"The Arab Journal of Interventional Radiology","volume":"3 8","pages":"054 - 062"},"PeriodicalIF":0.0,"publicationDate":"2024-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141701023","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}

Stent diameter, technical success, clinical outcomes, and adverse events were assessed for both groups.\u0000 Results TIPS was created for the overdilation group (n = 35, 57 ± 11 years, 69% male; MELD: 14 ± 5) and control group (n = 35, 57 ± 11 years, 83% male; MELD: 14 ± 5). Overdilation to 12 mm adequately reduced PSG by more than 50% (55 vs. 65% in the control group, p = 0.11). The stent diameter was larger in the overdilation group on cross-sectional imaging (9.8 ± 0.2 vs. 9.5 ± 0.4 mm, p < 0.001), with an estimated 57% higher volume flow rate (p = 0.002). Patients were followed for a median of 11.3 months (range: 0.03–75) and 15.6 months (range: 0.03–106) in the overdilation and control groups, respectively. There was an equivalent rate of ascites resolution (56 vs. 63%, p = 0.68) and rebleeding (13 vs. 17%, p = 0.82) in the overdilation and control groups, with a similar risk of new-onset hepatic encephalopathy (41 vs. 33%, p = 0.51) and TIPS occlusion (11 vs. 9%, p = 0.69). Overdilation did not result in any instance of stent fracture.\u0000 Conclusion Overdilation of 10-mm Viatorr stents with 12 mm balloons may provide benefit by potentially reducing PSG further for patients initially having inadequate PSG reduction with short-term safety.","PeriodicalId":507357,"journal":{"name":"The Arab Journal of Interventional Radiology","volume":" 12","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140683760","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 questionnaire contained eight questions that were grouped into three sections: (1) whether IVC stents have been performed or not, (2) the number of IVC stent placements, and (3) the basic strategy of antithrombotic therapy for pre-, intra-, and post-IVC stent placement.\u0000 Results Of the 114 institutions, 38 responses (33%) were collected. Twenty-four of the 38 institutions (63%) had performed IVC stent placement during the study period. The mean number of IVC stent placements during the study period was 3.4 cases per institution. The most frequently selected antithrombotic therapeutic strategies pre-, intra-, and post-stenting were no antithrombotic therapy (62.5%), anticoagulation therapy (54.2%), and no antithrombotic therapy (41.7%).\u0000 Conclusion This study has revealed there is no consensus regarding antithrombotic therapy for IVC stent placement in Japan.

We describe the case of a 76-year-old female who presented with a left-sided renal artery aneurysm and 11 mm aneurysm neck. Renal arteriography of the superior pole branch was performed, lower pole was stented, and a retrievable stent was placed in the inferior branch for the purpose of stent-assisted coiling. Penumbra detachable coils were deposited through the stent struts to jail them in with successful embolization of the aneurysm. Endovascular treatment of wide-neck renal artery aneurysms has the potential to be a successful treatment alternative in patients where surgical intervention is contraindicated.

This narrative review delves into the potential applications of large language models (LLMs) in VIR, with a focus on Chat Generative Pre-Trained Transformer (ChatGPT) and similar models. LLMs, designed for natural language processing, exhibit promising capabilities in clinical decision-making, workflow optimization, education, and patient-centered care. The discussion highlights LLMs' ability to analyze extensive medical literature, aiding radiologists in making informed decisions. Moreover, their role in improving clinical workflow, automating report generation, and intelligent patient scheduling is explored. This article also examines LLMs' impact on VIR education, presenting them as valuable tools for trainees. Additionally, the integration of LLMs into patient education processes is examined, highlighting their potential to enhance patient-centered care through simplified and accurate medical information dissemination. Despite these potentials, this paper discusses challenges and ethical considerations, including AI over-reliance, potential misinformation, and biases. The scarcity of comprehensive VIR datasets and the need for ongoing monitoring and interdisciplinary collaboration are also emphasized. Advocating for a balanced approach, the combination of LLMs with computer vision AI models addresses the inherently visual nature of VIR. Overall, while the widespread implementation of LLMs in VIR may be premature, their potential to improve various aspects of the discipline is undeniable. Recognizing challenges and ethical considerations, fostering collaboration, and adhering to ethical standards are essential for unlocking the full potential of LLMs in VIR, ushering in a new era of healthcare delivery and innovation.","PeriodicalId":507357,"journal":{"name":"The Arab Journal of Interventional Radiology","volume":" 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140684331","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}
