Project description:Interventional radiologists are playing an increasingly important role in pediatric urologic intervention, working closely with the pediatric urologist. Interventional radiologists are frequently asked to establish percutaneous access to the renal collecting system prior to nephrolithotomy. Additionally, procedures such as percutaneous nephrostomy, ureteral stent placement and exchange, and renal parenchymal biopsy are frequently encountered requests. This article will review these common procedures and highlight techniques and pathology that are unique to the pediatric population.

Project description:PURPOSE:Integrated interventional radiology (IR) residencies recently underwent their second year in the match, the first year of which involved only a limited number of programs. Now that students can choose to enter IR directly, student perceptions of IR vs diagnostic radiology (DR) are of paramount importance. METHODS:We surveyed first- through fourth-year medical students and radiology residents regarding interest in IR vs DR. RESULTS:Students considering a radiological career expressed more interest in IR than DR. Conversely, residents expressed more interest in DR. CONCLUSIONS:Medical student advisors and IR programs should continue to anticipate a high number of applications for integrated IR positions.

Project description:BackgroundHealthcare is a highly polluting industry and attention to the need for making this sector more sustainable is growing. The interventional radiology (IR) department is a relatively unique department in the hospital because of its synergetic use of both imaging equipment and medical instruments. As a result, the interventional radiology department causes a significant environmental burden in terms of energy usage, waste and water pollution. The aim of this study was to explore the current state of sustainability within IR by conducting a survey and interviews among IR specialists in the Netherlands.ResultsThe main findings of this study were that there is a high awareness for the need of sustainability within IR, but that there is still limited action. Previous studies point towards the various opportunities in the field of energy, waste and water pollution, yet our study unveils these opportunities are often not implemented because of (1) sustainability not being a priority, (2) a dependency on employees, and (3) factors that simply cannot be changed by an individual IR department or hospital. Generally, our study indicates that there is a willingness to become more sustainable, but that the current system involves a wide range barriers that hinder true change. Furthermore, it seems that no one is currently taking the lead and a leading role from higher management, government, healthcare authorities or professional societies is lacking.ConclusionsDespite the hurdles found in our study, IR departments can implement several improvements. An important factor is that sustainability should not lead to lower convenience for employees, which can be ensured by a sufficiently designed waste infrastructure and behavioral nudges. Furthermore, there lies an opportunity in more collaboration between IR departments in knowledge sharing and open innovation.

Project description:Venous thromboembolism (VTE) is an illness that has a potentially life-threatening condition that affects a large percentage of the global population. VTE with pulmonary embolism (PE) is the third leading cause of death after myocardial infarction and stroke. In the first three months after an acute PE, there is an estimated 15% mortality among submassive PE, and 68% mortality in massive PE. Current guidelines suggest fibrinolytic therapy regarding the clinical severity, however some studies suggest a more aggressive treatment approach. This review will summarize the available endovascular treatments and the different techniques with its indications and outcomes.

Project description:Purpose To determine the prevalence of and risk factors for needlesticks in interventional radiology physicians, as well as the attitudes, behaviors, and conditions that promote or interfere with reporting of these injuries. Materials and Methods A total of 3889 interventional radiologists from academic and private practice in the United States were surveyed by emailing all interventional radiologist members of the Society of Interventional Radiology, including attending-level physicians and trainees (April-August 2016). The institutional review board waived the need for consent. Questions inquired about the nature, frequency, and type of needlestick and sharps injuries and whether and to whom these incidents were reported. Stepwise regression was used to determine variables predicting whether injuries were reported. Results In total, 908 (23%) interventional radiologists completed at least a portion of the survey. Eight hundred fourteen (91%) of 895 respondents reported a prior needlestick injury, 583 (35%) of 895 reported at least one injury while treating an HIV-positive patient, and 626 (71%) of 884 reported prior training regarding needlestick injury. There was, on average, one needlestick for every 5 years of practice. Most needlestick or sharps injuries were self inflicted (711 [87%] of 817) and involved a hollow-bore device (464 [56%] of 824). Only 566 (66%) of 850 injuries were reported. The most common reasons for not reporting included perceived lack of utility of reporting (79 [28%] of 282), perceived low risk for injury (56 [20%] of 282), noncontaminated needle (53 [19%] of 282), too-lengthy reporting process (37 [13%] of 282), and associated stigma (23 [8%] of 282). Only 156 (25%) of 624 respondents informed their significant other. Stepwise regression assessing variables affecting the likelihood of reporting showed that male sex (P = .009), low-risk patient (P < .0001), self injury (P = .010), trainee status (P < .0001), and the total number of prior injuries (P = .019) were independent predictors of not reporting. Conclusion Needlestick injuries are ubiquitous among interventional radiologists and are often not reported. © RSNA, 2017 Online supplemental material is available for this article.

Project description:The kidney is the third most common abdominal organ to be injured in trauma, following the spleen and liver, respectively. Several classification systems convey the severity of injury to kidneys, ureter, bladder, and urethra. The most commonly used classification scheme is the American Association for the Surgery of Trauma (AAST) classification of blunt renal injuries, which grades renal injury according the size of laceration and its proximity to the renal hilum. Ureteral injury is graded according to its extent relative to the circumference of the ureter and the extent of associated devascularization. Bladder injury is graded according to its location relative to the peritoneum. Urethral injury is graded according to the extent of damage to surrounding anatomic structures. Although these classification schema may not be always used in common parlance, they do help delineate most important features of urologic tract injury that impact patient management and interventions.

Project description:OBJECTIVES:To assess awareness and knowledge of Interventional Radiology (IR) in a large population of medical students in 2019. METHODS:An anonymous survey was distributed electronically to 9546 medical students from first to sixth year at three European medical schools. The survey contained 14 questions, including two general questions on diagnostic radiology (DR) and artificial intelligence (AI), and 11 on IR. Responses were analyzed for all students and compared between preclinical (PCs) (first to third year) and clinical phase (Cs) (fourth to sixth year) of medical school. Of 9546 students, 1459 students (15.3%) answered the survey. RESULTS:On DR questions, 34.8% answered that AI is a threat for radiologists (PCs: 246/725 (33.9%); Cs: 248/734 (36%)) and 91.1% thought that radiology has a future (PCs: 668/725 (92.1%); Cs: 657/734 (89.5%)). On IR questions, 80.8% (1179/1459) students had already heard of IR; 75.7% (1104/1459) stated that their knowledge of IR wasn't as good as the other specialties and 80% would like more lectures on IR. Finally, 24.2% (353/1459) indicated an interest in a career in IR with a majority of women in preclinical phase, but this trend reverses in clinical phase. CONCLUSIONS:Development of new technology supporting advances in artificial intelligence will likely continue to change the landscape of radiology; however, medical students remain confident in the need for specialty-trained human physicians in the future of radiology as a clinical practice. A large majority of medical students would like more information about IR in their medical curriculum; almost a quarter of students would be interested in a career in IR.

Project description:ObjectiveTo characterize use of uterine tamponade and interventional radiology procedures.MethodsThis retrospective study analyzed uterine tamponade and interventional radiology procedures in a large administrative database. The primary outcomes were temporal trends in these procedures 1) during deliveries, 2) by hospital volume, and 3) before hysterectomy for uterine atony or delayed postpartum hemorrhage. Three 3-year periods were analyzed: 2006-2008, 2009-2011, and 2012-2014. Risk of morbidity in the setting of hysterectomy with uterine tamponade and interventional radiology procedures as the primary exposures was additionally analyzed in adjusted models.ResultsThe study included 5,383,486 deliveries, which involved 6,675 uterine tamponade procedures, 1,199 interventional radiology procedures, and 1,937 hysterectomies. Interventional radiology procedures increased from 16.4 to 25.7 per 100,000 delivery hospitalizations from 2006-2008 to 2012-2014 (P<.01), and uterine tamponade increased from 86.3 to 158.1 (P<.01). Interventional radiology procedures use was highest (45.0/100,000 deliveries, 95% CI 41.0-48.9) in the highest and lowest (8.9/100,000, 95% CI 7.1-10.7) in the lowest volume quintile. Uterine tamponade procedures were most common in the fourth (209.8/100,000, 95% CI 201.1-218.5) and lowest in the third quintile (59.8/100,000, 95% CI 55.1-64.4). Interventional radiology procedures occurred before 3.3% of hysterectomies from 2006 to 2008 compared with 6.3% from 2012 to 2014 (P<.05), and uterine tamponade procedures increased from 3.6% to 20.1% (P<.01). Adjusted risks for morbidity in the setting of uterine tamponade and interventional radiology before hysterectomy were significantly higher (adjusted risk ratio [aRR] 1.63, 95% CI 1.47-1.81 and aRR 1.75 95% CI 1.51-2.03, respectively) compared with when these procedures were not performed.ConclusionThis analysis found that uterine tamponade and interventional radiology procedures became increasingly common over the study period, are used across obstetric volume settings, and in the setting of hysterectomy may be associated with increased risk of morbidity, although this relationship is not necessarily causal.

Project description:Contrast-induced nephropathy (CIN) is a widely recognized and clinically significant problem in patients undergoing an increasing number of minimally invasive procedures that require contrast administration. Contrast-induced nephropathy is the third most common cause of hospital-acquired renal failure and has significant prognostic implications on patient outcomes. Interventional practitioners are faced with challenging decisions regarding prophylaxis and patient management. The major risk factor for developing CIN is preexisting renal dysfunction, particularly in association with diabetes. Patients are considered to be at risk when estimated glomerular filtration rate (eGFR) or estimated creatinine clearance (eC(Cr)) is less than 60. The cornerstone of prevention of CIN is appropriate risk stratification, intravenous hydration with normal saline or sodium bicarbonate, appropriate withholding of nephrotoxic medications, use of low or iso-osmolar contrast media, and various intraprocedural methods for iodinated contrast dose reduction. Although N-acetylcysteine administration is popular, it remains unproven. Practitioners must be familiar with prevention strategies and diagnosis of CIN to minimize its clinical impact.
