    BACKGROUND: Resuscitative endovascular balloon occlusion of the aorta (REBOA) is increasingly employed in patients with hemorrhagic shock and cardiovascular collapse; however, its impact on mortality remains controversial. Differences in geographic regions and patient populations may influence clinical outcomes. METHODS: We conducted a systematic review and meta-analysis of observational studies comparing mortality between patients receiving REBOA and those managed without REBOA. Pooled odds ratios (ORs) and 95% confidence intervals (CIs) were calculated using random-effects models. Subgroup analyses were performed according to propensity score (PS) matching, trauma versus non-trauma populations, and geographic regions. RESULTS: A total of 10 studies involving 18,611 patients were included. Overall, REBOA was not associated with a significant reduction in mortality compared with non-REBOA (pooled OR = 0.52, 95% CI: 0.19-1.39, p = 0.19). In PS-matched studies, the pooled OR was 0.82 (95% CI: 0.34-1.98, p = 0.66), whereas in non-PS-matched studies it was 0.40 (95% CI: 0.12-1.26, p = 0.12). Geographic analyses revealed no significant mortality benefit in either Western studies (OR = 0.47, 95% CI: 0.12-1.89; p = 0.29) or non-Western studies (OR = 0.60, 95% CI: 0.11-3.38; p = 0.56). No survival benefit was observed among trauma patients (OR = 0.57, 95% CI: 0.20-1.61; p = 0.29), whereas a significant reduction in mortality was observed in non-trauma patients (OR = 0.21, 95% CI: 0.05-0.88; p = 0.03). CONCLUSIONS: In this systematic review and meta-analysis, REBOA was not associated with a significant reduction in mortality in the overall population or in trauma patients. However, in a single small non-trauma study (n = 53), REBOA was associated with significantly reduced mortality; this finding is exploratory and requires confirmation in larger prospective studies. These findings suggest that the clinical benefit of REBOA may depend on patient population and underlying etiology of hemorrhage.

    IntroductionBlunt trauma to the external iliac artery (EIA) is rare but potentially fatal. Endovascular stent-graft placement is used to control hemorrhage and restore limb perfusion. However, the safety profile and potential complications associated with stent-graft treatment are not well documented. We report a case of EIA injury following blunt trauma complicated by stent-graft deployment into a false lumen, successfully managed with an endovascular rescue technique.Case ReportAn 88-year-old man sustained blunt pelvic trauma with active extravasation from the left EIA. Initially, a covered stent-graft was deployed, which inadvertently caused arterial occlusion due to placement within a false lumen. A rescue procedure was performed using an endovascular approach, where a guidewire was advanced through the perigraft space and snared to establish a pull-through technique. Over this, a second stent-graft was deployed within the perigraft space, restoring flow through the true lumen. Follow-up computed tomography images confirmed successful recanalization and persistent exclusion of the false lumen.ConclusionThis case highlights the potential for stent-graft misplacement in EIA trauma and the importance of ensuring access to the true lumen. Accessing the perigraft space and placing an additional stent-graft represents a new therapeutic approach to achieve recanalization in similar complex vascular injuries.

    An 87-year-old woman was hospitalized for liver abscesses and cholangitis due to common bile duct stones. She developed worsening anemia and abdominal pain. Contrast-enhanced computed tomography revealed an intrahepatic pseudoaneurysm and an arteriovenous fistula between the hepatic arteries and inferior vena cava. The initial endovascular treatment was transarterial embolization. The pseudoaneurysm was embolized with an N-butyl-2-cyanoacrylate mixture, and the inflow arteries of the arteriovenous fistula were embolized with microcoils. However, the residual perfusion of the arteriovenous fistula remained. A second endovascular treatment was performed using the transarterial and transvenous approaches. The inflow arteries were embolized using microcoils and gelatin sponges and the dominant outflow vein was embolized using microcoils, resulting in the disappearance of the perfusion in the arteriovenous fistula.

    In this report, we present a case of gastrointestinal bleeding due to splenic artery rupture, which required repeated transcatheter arterial embolization (TAE) within a short period of time. A 75-year-old man with pancreatic carcinoma was transported to our hospital with active hematemesis and vital signs consistent with shock. Contrast-enhanced computed tomography images showed a pancreatic tumor that had caused a pseudoaneurysm of the splenic artery to rupture. The pseudoaneurysm was embolized using only an N-butyl-2-cyanoacrylate (NBCA) and lipiodol mixture. However, hematemesis with signs of shock recurred 13 h later, and angiography showed rebleeding from the origin of the splenic artery. The splenic artery was subsequently embolized using an NBCA and lipiodol mixture. Repeated TAE finally controlled the hemorrhage; however, asymptomatic splenic infarction and hepatic infarction occurred due to nontarget embolization.

    Pelvic fractures are common in cases of blunt trauma, which is strongly associated with mortality. Transcatheter arterial embolization is a fundamental treatment strategy for fatal arterial injuries caused by blunt pelvic trauma. However, vascular injuries due to blunt pelvic trauma can show various imaging findings other than arterial hemorrhage. We present a pictorial review of common and uncommon vascular injuries, including active arterial bleeding, pseudoaneurysm, arteriovenous fistula, arterial occlusion, vasospasm, and active venous bleeding. Knowledge of these vascular injuries can help clinicians select the appropriate therapeutic strategy and thus save lives.

    OBJECTIVE: The objective of this study was to determine the association between arterial embolisation (AE) for pelvic fractures and death. METHODS: The study had a retrospective design, using data from a nationwide population based prospective registry of trauma patients in Japan. This propensity score matched study included all adult patients from the registry with pelvic fractures between January 2004 and December 2018. The primary outcome was hospital death. Secondary outcomes included 28 day survival and length of hospital stay (LOS) in days. Multivariable logistic regression analyses were performed to control confounding variables, including patient, clinical, and hospital related variables; concomitant trauma; severe trauma; and haemodynamic instability. A conditional logistic regression analysis was performed to assess the association between treatment of pelvic fracture with AE and hospital mortality rate. RESULTS: Among 17 670 eligible patients with pelvic fractures, 2 379 (13.5%) underwent AE (AE group) and 1 512 (8.6%) died in the hospital. After one to one propensity matching with 2 138 patients from each group (AE and non-AE), the hospital mortality rate was significantly lower in the AE group than in the non-AE group (15.0% vs. 18.1%; p = .007). The AE group had significantly lower mortality (odds ratio; 95% confidence interval [CI] 0.60; 0.43 - 0.84; p = .003) and a significantly higher 28 day mean survival rate than the non-AE group (0.89; 95% CI 0.87 - 0.90 vs. 0.86; 0.85 - 0.88; p = .003), although there was no significant difference in the LOS (48 days vs. 46 days; p = .11). CONCLUSION: This propensity score matched analysis showed an association between AE for pelvic fractures and lower hospital mortality rates. The findings in this large nationwide cohort study provide strong evidence for the benefit of embolisation for patients with pelvic fractures.

    BACKGROUND: Extravasation on contrast-enhanced computed tomography (CECT) is a helpful indicator of the need for transcatheter arterial embolization (TAE) for pelvic fractures. However, previous reports were inconsistent on cases in which angiography is necessary, even though there is no extravasation on computed tomography. This study aimed to describe and analyze the contradictory findings in cases where extravasation is observed on angiography but not on CECT, to contribute to improved management of patients with pelvic fractures. METHODS: This was a retrospective single-center study. Patients with pelvic fractures who underwent CECT and TAE between 2014 and 2020 were included. We classified the patients into three groups: CECT and angiography with extravasation (CT+Angio+), CECT with no extravasation and angiography with extravasation (CT-Angio+), and CECT with extravasation and angiography without extravasation (CT+Angio-). RESULTS: A total of 113 patients were included in the study: the CT+Angio+ group had 54 patients, CT-Angio+ group, 47; and CT+Angio- group, 12. The CT-Angio+ group had a significantly longer time from arrival to CECT than the CT+Angio+ group (27 minutes vs. 23 minutes, p < 0.05). The CT-Angio+ group had significantly more blood transfusions (fresh frozen plasma, platelets) within 24 hours than the CT+Angio- group did (p < 0.05), and ventilator management days (p < 0.05) and intensive care unit stays (p < 0.05) were significantly longer. CONCLUSION: There was no significant difference in outcomes among the three groups. There was no difference in severity, transfusion volume, or mortality in patients with pelvic fractures needing TAE, classified as CT-Angio+, compared with that of CT+Angio+ patients. Even in the absence of extravasation in the pelvic region on CECT, angiography or TAE may still be necessary. LEVEL OF EVIDENCE: Therapeutic/Care Management, Level IV.

    Endoscopic ultrasonography has become a routine procedure in clinical practice and is widely accepted as a safe procedure. Previous studies have reported that severe bleeding rarely occurs even when performing fine-needle aspiration biopsy. Severe hemorrhage following non-interventional endoscopic ultrasonography has never been reported. We herein report a case of hemorrhagic shock due to hemoperitoneum caused by a ruptured right gastroepiploic artery consequent to a diagnostic endoscopic ultrasonography. The patient was administered two antithrombotic agents. An extensive diagnostic workup contributed to the correct diagnosis, which led to a successful treatment by transcatheter arterial embolization. Endoscopists should be aware of this rare, but potentially fatal, adverse event of endoscopic ultrasonography.

    Resuscitative endovascular balloon occlusion of the aorta (REBOA) is performed in patients with hemorrhagic shock who develop massive subdiaphragmatic bleeding. This procedure enables rapid and less invasive aortic blockade compared to resuscitative thoracotomy and aortic cross-clamp procedures. However, the REBOA procedure is often blindly performed in the emergency department without fluoroscopy, and the appropriateness of the procedure may be evaluated on computed tomography (CT) after REBOA. Therefore, radiologists should be familiar with the imaging features of REBOA. We present a pictorial review of the radiological findings of REBOA along with a description of the procedure, its complications, and pitfalls.

    This retrospective study included 65 patients who underwent multidetector computed tomography (MDCT) carotid angiography; 28 patients were &lt;70 years old (group 1), and 37 were ≥70 years old (group 2). Each low-attenuation (&lt;30 Hounsfield units [HU]) plaque volume (LPV) and total uncalcified plaque volume ([TUPV] ≤150 HU) were semiautomatically measured on each aortic arch and internal carotid artery (ICA) curved planar reformations (CPR), using MDCT angiographic data. Correlation coefficients were employed to assess the impact of each plaque volume on various factors including ICA stenosis. The correlations (r &gt; 0.5) were observed between aortic LPV and each ICA stenosis ratio and &gt;30% stenosis in group 1, between aortic TUPV and male gender in group 1, and between ICA-TUPV and each aortic TUPV or the largest plaque thickness in group 2. Marginal correlations were observed between hyperlipidemia and aortic LPV and ICA-TUPV in group 1. There was no association between cerebral infarction and the aortic and ICA plaques. Both the aortic arch and ICA plaque volumes can be measured clinically. The increasing aortic LPV may be a significant factor associated with the development of ICA stenosis in patients younger than 70 years old.
