Abstract
Background Endovascular embolization techniques are nowadays well established in the management of acute arterial bleedings. However, the education and training of the next generation of interventionalists are still based on the traditional apprenticeship model, where the trainee learns and practices directly at the patient, which potentially affects the patient’s safety. The objective of this study was to design and develop a standardized endovascular simulation concept for the training of acute bleeding embolizations, based on real-life cases. Results An adaptable and cost-effective endovascular simulator was developed using an in-house 3D print laboratory. All thoracic and abdominal acute bleeding embolizations over more than a year with appropriate pre-interventional computed tomography scans were included to manufacture 3D printed vascular models. A peristaltic pump was used to generate pulsatile flow curves. Forty embolization cases were engaged in this study, and 27 cases were fully reproduced in the simulation setting (69.23%). The simulation success was significantly lower in pulmonary embolizations (p = 0.031) and significantly higher in soft tissue (p = 0.032) and coil embolizations (p = 0.045). The overall simulation success was 7.8 out of 10 available points. Conclusions Using stereolithography 3D printing in a standardized simulation concept, endovascular embolization techniques for treating acute internal hemorrhages in the chest and abdomen can be simulated and trained based on the patient-specific anatomy in a majority of the cases and at a broad spectrum of different causes.

Abstract
Trauma accounts for a third of the deaths in Western countries, exceeded only by cardiovascular disease and cancer. The high risk of massive bleeding, which depends not only on the type of fractures, but also on the severity of any associated parenchymal injuries, makes pelvic fractures one of the most life-threatening skeletal injuries, with a high mortality rate. Therefore, pelvic trauma represents an important condition to correctly and early recognize, manage, and treat. For this reason, a multidisciplinary approach involving trauma surgeons, orthopedic surgeons, emergency room physicians and interventional radiologists is needed to promptly manage the resuscitation of pelvic trauma patients and ensure the best outcomes, both in terms of time and costs. Over the years, the role of interventional radiology in the management of patient bleeding due to pelvic trauma has been increasing. However, the current guidelines on the management of these patients do not adequately reflect or address the varied nature of injuries faced by the interventional radiologist. In fact, in the therapeutic algorithm of these patients, after the word “ANGIO”, there are no reports on the different possibilities that an interventional radiologist has to face during the procedure. Furthermore, variations exist in the techniques and materials for performing angioembolization in bleeding patients with pelvic trauma. Due to these differences, the outcomes differ among different published series. This article has the aim to review the recent literature on optimal imaging assessment and management of pelvic trauma, defining the role of the interventional radiologist within the multidisciplinary team, suggesting the introduction of common and unequivocal terminology in every step of the angiographic procedure. Moreover, according to these suggestions, the present paper tries to expand the previously drafted algorithm exploring the role of the interventional radiologist in pelvic trauma, especially given the multidisciplinary setting.

Do we really need the arterial phase on CT in pelvic trauma patients? Emerg Radiol 2020; 28:37-46.

Abstract
PURPOSE To evaluate whether an arterial phase scan improves the diagnostic performance of computed tomography to identify pelvic trauma patients who received angiographic intervention on demand of the trauma surgeon. METHODS This retrospective single-center study was performed at an academic Scandinavian trauma center with approximately 2000 trauma admissions annually. Pelvic trauma patients with arterial and portal venous phase CT from 2009 to 2015 were included. The patients were identified from the institutional trauma registry. Images were interpreted by two radiologists with more than 10 years of trauma radiology experience. Positive findings for extravasation on portal venous phase alone or on both arterial and portal venous phase were compared, with angiographic intervention as clinical outcome. RESULTS One hundred fifty-seven patients (54 females, 103 males) with a median age of 45 years were enrolled. Sixteen patients received angiographic intervention. Positive CT findings on portal venous phase only had a sensitivity and specificity of 62% and 86%, vs. 56% and 93% for simultaneous findings on arterial and portal venous phase. Specificity was significantly higher for positive findings in both phases compared with portal venous phase only. Applying a threshold > 0.9 cm of extravasation diameter to portal venous phase only resulted in sensitivity and specificity identical to those of both phases. CONCLUSION Arterial phase scan in addition to portal venous phase scan did not improve patient selection for angiography. Portal venous phase extravasation size alone may be used as an imaging-based biomarker of the need for angiographic intervention.

Abstract
Minimally invasive transcatheter embolization is a common nonsurgical procedure in interventional radiology used for the deliberate occlusion of blood vessels for the treatment of diseased or injured vasculature. A wide variety of embolic agents including metallic coils, calibrated microspheres, and liquids are available for clinical practice. Additionally, advances in biomaterials, such as shape-memory foams, biodegradable polymers, and in situ gelling solutions have led to the development of novel preclinical embolic agents. The aim here is to provide a comprehensive overview of current and emerging technologies in endovascular embolization with respect to devices, materials, mechanisms, and design guidelines. Limitations and challenges in embolic materials are also discussed to promote advancement in the field.

Variability in pelvic packing practices for hemodynamically unstable pelvic fractures at US level 1 trauma centers. Patient Saf Surg 2019; 13:3. [PMID: 30675184 PMCID: PMC6334446 DOI: 10.1186/s13037-019-0183-7] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/28/2018] [Accepted: 01/07/2019] [Indexed: 12/13/2022] Open
Abstract
BACKGROUND Mortality from hemodynamically unstable pelvic fractures remains high. Guidelines offer varying care approaches including the use of pelvic packing (PP), which was recently adopted for potential control of bleeding for this condition. However, the implementation of PP is uncertain as the debate on the optimal resuscitation strategy, angioembolization or PP continues. The study was designed to assess current practices among level 1 trauma centers in the US in regard to PP treatment for hemodynamically unstable pelvic fractures. METHODS A cross-sectional survey was created to assess when to apply PP, application approach, and the respondent's anecdotal perception on safety and effectiveness. Trauma Medical Directors at 158 US level 1 trauma centers were sent biweekly email invitations for 3 months. Participants were allowed to skip questions for any reason. The study hypothesis was that PP practices vary by US census bureau region, annual trauma admissions, and length of time in years since each trauma center received their respective level 1 trauma center designation. RESULTS Twenty-five percent (40/158) of trauma medical directors participated and 75% (118/158) of the trauma medical directors did not participate. Of those who took the survey, 36/40 (90%) completed the survey and 4/40 (10%) partially completed the survey. Only 36 trauma medical directors responded on their perception of safety and effectiveness; 72% (26/36) of participants perceived PP as safe, whereas only a third (12/36) of participants perceived PP as effective. There were 25 trauma medical directors who provided the sequence of treatment modalities utilized at their level 1 trauma center, 76% (19/25) of participants reported that PP is utilized as the third or fourth priority. None of the participating level 1 trauma centers reported a preference towards utilization of PP as the first priority treatment. Half of the participants reported a preference towards applying PP only as a last resort to control hemorrhage. Northeastern and Western level 1 trauma centers were significantly more likely than Midwestern and Southern level 1 trauma centers to have reported application of PP to all hemodynamically unstable patients (p = 0.05). Midwestern, Southern, and Western level 1 trauma centers were significantly more likely to have perceived PP as safe than Northeastern level 1 trauma centers (p = 0.04). All low-volume and 38% high-volume level 1 trauma centers perceived PP to increase infection risks, (p = 0.03). We observed no association between the length of time each trauma center was designated a level 1 trauma center, and all participant responses. CONCLUSION Controversy and varying anecdotal perception regarding safety and effectiveness of PP prevails among trauma medical directors at level 1 trauma centers in the US.

Abstract
PURPOSE To assess the reliability of a prototype automated supplying artery tracking software (ASATS) using multidetector-row CT (MDCT) images in emergent TAE. MATERIALS AND METHODS Consecutive 53 patients underwent 57 sessions of emergent TAE during 7 months. Twenty-one cases were excluded due to a lack of CT data (n = 12) or negative angiographic findings (n = 9). Remaining 34 sessions of TAE and MDCT images in 32 patients (mean age 62.9 years; age range 37-92 years) were enrolled. ASATS was retrospectively conducted for the identification of supplying arteries which were confirmed with angiography (automated method). Manual modification was added as needed (semi-automated method). Two observers independently reviewed the MDCT images to detect supplying arteries (manual method). Detectability of supplying artery and time to analysis were compared among the automated, semi-automated, and manual methods by both observers. RESULTS A total of 64 bleeding sites were demonstrated on angiography. The detectability was 28 (43.8%) for automated method, 53 (82.8%) for semi-automated method, 55 (85.9%) for observer 1, and 58 (90.6%) for observer 2. Detectability of semi-automated method was significantly better than of automated method (P = 0.000) and comparable with manual method by both observers (P = 0.193 and 0.081). Average time to analysis was 185.4 s for automated method, 297.2 s for semi-automated method, 186.2 s for observer 1, and 243.7 s for observer 2. CONCLUSION ASATS has a sufficient ability to identify supplying arteries of bleeding by adding manual modification as needed and can be used for emergent TAE.
