Materials and Methods A retrospective chart review was performed of all percutaneous transhepatic biliary drains completed at our institution from 2009 to 2018. Chart review of complications and interventions was recorded. Chi-squared and Fisher’s exact tests were used to compare percutaneous transhepatic biliary drains performed in patients with liver transplants (n = 62) to those with native livers (n = 285). Results There was a statistically significant difference in the frequency of complications of percutaneous transhepatic biliary drains in patients with liver transplants (61%) compared with those with native livers (13%), χ2(1) = 9.59, p<0.01. There was a statistically significant increased frequency of worsening liver function, sepsis, bile leak, arterial and portal venous bleeds, and secondary complications in those with liver transplants. The median number of days until the complication occurred for those with liver transplants was nearly three times longer than those with native livers. The most common subsequent intervention for patients with liver transplants was placement of a new drain (53%), whereas those with native livers was drain upsize (70%). Conclusion Complications including vascular injury, sepsis, bile leak, and worsening liver function after percutaneous transhepatic biliary drains occurred more commonly in patients with liver transplants versus native livers.","PeriodicalId":32940,"journal":{"name":"The Arab Journal of Interventional Radiology","volume":"45 1","pages":"011 - 015"},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1055/s-0041-1730114","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"58141606","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}

Results Technical success was achieved in 97% (n = 36/37) and clinical success was achieved in 89% (33/37) of the procedures. One procedure failed recanalization of chronic total occlusion of the left subclavian vein, and the patient required fistula embolization due to severe arm swelling. Another procedure failed initially to recanalize long-segment occlusion involving the right subclavian vein/brachiocephalic vein and superior vena cava in a patient with a history of Hickman line and left-sided CIED. This was successfully recanalized and angioplastied on a subsequent session. No lead fracture or dislodgment was documented in any procedure. No procedure-related complication was documented within 2 weeks after the angioplasty. Six-month primary patency was achieved in 62% (23/37) of the procedures. Ten patients (66%) required an average of 1.4 reinterventions (range: 1–4 interventions) during the follow-up time with mean time to reintervention of 318 days (5–1,380 days).

Methods Eighty-six AVS procedures were performed in 81 patients between August 2013 and March 2020. A selectivity index was calculated for each case by dividing the measured left adrenal vein cortisol level by the peripheral vein cortisol level. Successful “target” left adrenal vein catheterization was confirmed in cases with a selectivity index of three or greater. Intraprocedural AVS fluoroscopic images were selected that demonstrated catheter position in the left adrenal vein. Lateral distance from the catheter tip in the left adrenal vein to the lateral margin of the left pedicle at the associated vertebral body level was measured. Results Mean patient age was 56.4 years (range: 19–80 years) and 48 (59.3%) patients were male. Target sampling in the left adrenal vein was confirmed in 82 (95.3%) cases. In 78 (95.1%) targeted cases, the catheter terminated less than 25 mm from the left lateral pedicle at a mean distance of 11.2 mm. The catheter was most frequently placed at the T12 and L1 vertebral body levels. Four (4.7%) cases demonstrated nontarget catheter positioning, two (50.0%) of these cases were within 25 mm. Conclusion The position of the left adrenal vein is generally located in a predictable position relative to bony landmarks. By utilizing these landmarks, positioning of the sampling catheter during AVS can be more reliable with the potential to avoid repeat procedures and delays in patient care.","PeriodicalId":32940,"journal":{"name":"The Arab Journal of Interventional Radiology","volume":"5 1","pages":"025 - 029"},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1055/s-0041-1730113","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42664313","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}

Thorough knowledge of detailed prostatic artery (PA) anatomy is essential. Aims The aim of this study was to provide a pictorial review of PA anatomy and prevalence of related anatomical variants, in addition to other anatomical and radiation dose considerations. Settings and Design Case series and review of literature. Materials and Methods We performed PAE for 210 patients from November 2015 to November 2020 under local anesthesia only. Anatomy, procedure duration, fluoroscopy time, radiation dose, technical success, and complications were analyzed. Statistical Analysis Used Descriptive statistics were analyzed using Microsoft Excel software. Results A total of 210 patients (420 sides) were analyzed. Double arterial supply on the same side was noted in 12 patients (5.7%). In 10 patients (4.7%), only a unilateral PA was identified. In two patients (0.9%), no PA could be identified. Frequencies of PA origins were calculated. Penile, rectal, and vesical anastomoses were identified with 79 (18.8%), 54 (12.9%), and 41 (9.8%) of PAs, respectively. Median skin radiation dose, procedure time, and fluoroscopy time were 505 mGy, 73 and 38 minutes, respectively. Complications occurred in nine patients (4.3%), none of them was major. Conclusions Knowledge of PA anatomy is essential when treating BPH by PAE for optimum results. There is no enough evidence to support routine use of preoperative computed tomography angiography and intraoperative cone-beam computed tomography as means of improving safety or efficacy.","PeriodicalId":32940,"journal":{"name":"The Arab Journal of Interventional Radiology","volume":"5 1","pages":"003 - 010"},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1055/s-0041-1729134","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45354061","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}

This study sought to compare the incidence of new vertebral fractures in patients treated by vertebroplasty with that of those managed conservatively, while also assessing the potential risk factors contributing to the occurrence of these fractures. Materials and Methods The details of a total of 121 eligible subjects with radiologically proven osteoporotic vertebral fractures were retrieved from our archive between January 2010 and September 2019 and divided, based on the treatment method, into percutaneous vertebroplasty (PVP) (n = 60) and nonsurgical treatment (n = 61). The included subjects’ clinical data, demographic profiles, and imaging findings on plain radiography, CT, and MRI scans performed at baseline and within 24 months following treatment were reviewed and documented. Results The difference in the incidence of new fractures was statistically significant (p = 0.001), with rates of 70% (n = 32) in the vertebroplasty group and 30% (n = 14) in the conservatively treated cases reported at a median follow-up time point of approximately 4 months. The presence of liver disease (p = 0.037), a history of transplantation (p = 0.003), the use of steroids (p = 0.023), a low-bone mineral density (BMD) score (p = 0.023), and a higher number of fractures on baseline imaging (p = 0.013) were associated with a greater risk of subsequent vertebral fractures. Conclusions The incidence of acute fractures after PVP is higher than that among patients treated conservatively. Decision-making regarding the adoption of this intervention should take into consideration the risk factors leading to a greater risk of subsequent vertebral fractures, such as a higher number of fractures at baseline imaging, low-BMD score, patient comorbidities, and steroid use.","PeriodicalId":32940,"journal":{"name":"The Arab Journal of Interventional Radiology","volume":"9 9-10","pages":"035 - 040"},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1055/s-0041-1731603","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41309492","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}

Foundation doctors in the UK, however, are a neglected group, with little being done engage these doctors who are at a crucial juncture in their training. Objectives: The objective of the study is to assess Foundation Year 1 (FY1) doctors' understanding of and exposure to IR. Methods: FY1s from two teaching hospitals in the UK at the end of their first year of Foundation training were invited to take part in an 18-question survey, including 14 single-best-answer (SBA) questions. The questions examined knowledge of IR and other specialties. The SBAs were scored out 14 and the Student's t-test was used to compare IR and non-IR scores. Results: Questionnaires were given to 72 FY1 doctors and 52 (72.2%) were completed. The median score was 9/14 (64.3%) [4.5/14–12/14]. Questions relating to coronary intervention and neurosurgery scored best (96.2% and 94.3%, respectively). The mean score for IR-related questions was significantly lower than that for non-IR questions (51.5% vs. 81.1%, respectively, P < 0.0001). Participants who referred patients to IR at least once per month scored higher than those who rarely referred (60.5% vs. 47.2%, respectively, P < 0.0084). Nearly 83.0% of participants expressed a desire to gain more exposure to IR. Conclusion: Although Foundation doctors have some understanding of IR, reflecting some exposure to the specialty, this remains deficient when compared with their knowledge of other specialties. This may be improved by the introduction of IR specific teaching during the Foundation program.","PeriodicalId":32940,"journal":{"name":"The Arab Journal of Interventional Radiology","volume":"4 1","pages":"096 - 101"},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44986250","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}
