Abstract
Splenic artery embolization (SAE) has become a favored alternative to splenectomy, offering a less invasive intervention for injured spleens while preserving spleen function. However, our understanding of the role that hemodynamics plays during embolization remains limited. In this study, we utilized patient-specific computational fluid dynamics (CFD) simulations to study distal and proximal embolization strategies commonly used in SAE. Detailed 3D computer models were constructed considering the descending aorta, various major visceral arteries, and the iliac arteries. Subsequently, the blood flow and pressure associated with different coil placement locations in proximal embolization were studied considering the collateral vessels. Coil induced variations in pressure fields were quantified and compared to baseline. The coil induced flow stagnation was also quantified with particle residence time. Distal embolization was modeled with Lagrangian particle tracking and the effect of particle size, release location, and timing on embolization outcome was studied. Our findings highlight the crucial role of collateral vessels in maintaining blood supply to the spleen following proximal embolization. It was demonstrated that coil location can affect distal pressure and that strategic coil placement guided by patient-specific CFD simulations can further reduce this pressure as desired. Additionally, the results point to the critical roles that particle size, release timing, and location play in distal embolization. Our study provides an early attempt to use patient-specific computer modeling for optimizing embolization strategies and ultimately improving patient outcomes during SAE procedures.

Abstract
PURPOSE We described clinical outcomes for patients with blunt splenic injuries treated with transarterial embolization (TAE) based on their hemodynamic status. MATERIALS AND METHODS This is a retrospective two-center study of adult patients with splenic injuries who underwent emergency TAE between January 2011 and December 2022. Patients were divided into two groups; hemodynamically unstable (HDU) and hemodynamically stable (HDS) patients. HDU patients were defined as transient- or non-responders to fluid resuscitation and HDS as responders. When immediate laparotomy was not possible for HDU patients, angiography and embolization were performed. The primary outcome was the survival discharge rate. Rebleeding and splenectomy rate was also investigated. RESULTS Of 38 patients underwent emergency TAE for splenic trauma, 17 were HDU patients and 21 were HDS patients. The survival discharge rate was 88.2 % (15/17) in the HDU- and 100 % in HDS patients (p = 0.193). Rebleeding rate was 23.5 % (4/17) in HDU- and 5.0 % (1/21) in HDS patients (p = 0.15). Splenectomy was required for one HDU patient (5.9 %) for rebleeding. CONCLUSION The survival discharge rate of TAE for splenic trauma in HDU patients was acceptable with a low rate of splenectomy. Further comparative studies of TAE versus operative management in HDU patients are needed to prove the usefulness of TAE.

Abstract
We present a case of prophylactic endovascular embolization in a 51-year-old man with necrotizing pancreatitis (NP) before undergoing endoscopic necrosectomy (EN). Contrast-enhanced CT imaging revealed the presence of a walled-off necrosis (WON) surrounding the pancreas, with the splenic artery coursing through the cavity. The splenic artery was embolized using n-butyl-2-cyanoacrylate (NBCA) and coils to mitigate the risk of massive bleeding in EN. A newly developed polytetrafluoroethylene (PTFE)-coated microcatheter was used to inject NBCA, enabling embolization of a long segment of the splenic artery without adhering to the vessel wall. Coils were placed distal and proximal to the embolized segment to optimize control. Over 5 sessions of EN, no massive bleeding was encountered. This report demonstrates the benefits of utilizing PTFE-coated microcatheters for enhanced safety and maneuverability during embolization with NBCA. Furthermore, it highlights the importance of prophylactic embolization during EN for managing NP.

Abstract
OBJECTIVE The objective of this systematic review was to compare the effectiveness of prophylactic angioembolization with observation as primary management strategies for patients with high-grade (grades 3-5) blunt trauma splenic injury. INTRODUCTION The spleen is frequently injured in abdominal trauma. Historical management practices involved splenectomy, but more recent evidence suggests an increased risk of severe infections and sepsis associated with this approach. Accordingly, non-operative management strategies, including prophylactic splenic artery embolization and clinical observation, have gained prominence. This systematic review with meta-analysis directly compares angioembolization with clinical observation for high-grade splenic injuries only, aiming to provide clarity on this matter amid ongoing debates and variations in clinical practice. INCLUSION CRITERIA This review included adult patients aged 15 years or older with high-grade splenic injuries (grade 3-5) due to blunt trauma. Outcomes of interest include the need for further intervention (failure of management), mortality, complications, red blood cell transfusion requirements, hospital length of stay, and intensive care unit length of stay. METHODS A comprehensive search of PubMed, Embase, and CINAHL (EBSCOhost), was performed with no restrictions on language or publication date. Gray literature was searched, including trial registries and relevant conference proceedings. After deduplication, 2 reviewers independently assessed titles and abstracts, and, subsequently, full-text articles for eligibility. Methodological quality of the included studies was assessed using standardized instruments from JBI. Data was extracted using predefined templates, and statistical meta-analysis was performed, where possible, using a random effects model. Heterogeneity was assessed using statistical methods, and potential publication bias was tested with a funnel plot. The Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) approach was used to evaluate the certainty of evidence. RESULTS Sixteen studies were included in this review. Methodological quality assessment indicated some risk of bias in most studies, with concerns primarily related to differences in injury severity and potential confounding factors. Meta-analysis revealed that prophylactic angioembolization significantly reduced risk of management failure by 57% (OR 0.43, 95% CI 0.28-0.68, I2=53%, 15 studies) and decreased patient mortality by 37% (OR 0.63, 95% CI 0.43-0.93, I2=0%, 9 studies) compared with clinical observation alone. There was a 47% reduction in risk of complications associated with prophylactic embolization compared with clinical observation (OR 0.53, 95% CI 0.29-0.95, I2=0%, 4 studies). Some statistical heterogeneity was observed, with I2 ranging from 0% to 53%. No significant differences were observed between the 2 management strategies for red blood cell transfusion requirements and hospital length of stay. CONCLUSIONS The results of this study support the use of prophylactic embolization for high-grade blunt trauma splenic injuries, indicated by lower failure of management rates, reduced need for additional interventions, lower mortality, and fewer complications.

Abstract
Celiac axis stenosis (CAS) is one of the most prevalent splanchnic arterial pathologies. It seldom results in clinically severe ischemic bowel disease because of the rich collateral circulation from the superior mesenteric artery. Knowledge about the collaterals in celiac artery stenosis guides various interventional procedures. Here, we describe a case of a 19-year-old female with American Association for the Surgery of Trauma (AAST) grade IV splenic injury found to have CAS. Distal splenic artery embolisation was performed via the collateral pathway through the pancreaticoduodenal arcade.

Abstract
Splenic artery embolization plays an important role in the management of various medical and surgical conditions that are non-traumatic in etiology, in addition to its well-established and widely discussed role in managing splenic trauma. In nontraumatic emergencies of catastrophic bleeding originating from the spleen or splenic artery, splenic artery embolization can be effective in achieving hemostasis as a definitive management, temporary stabilizing measure, or preoperative optimization technique. In addition to emergency clinical conditions, splenic artery embolization can be performed electively as an alternative to splenectomy for managing patients with hypersplenism. Herein, we report 6 cases of splenic artery embolization performed at our center to highlight its various indications. This article aims to demonstrate the role of splenic artery embolization in different clinical scenarios and the considerations behind the techniques employed through illustrative cases.

Abstract
PURPOSE Retrospective review of splenic artery embolization (SAE) outcomes performed for blunt abdominal trauma. MATERIALS AND METHODS 11-year retrospective review at a large level-1 Canadian trauma centre. All patients who underwent SAE after blunt trauma were included. Technical success was defined as angiographic occlusion of the target vessel and clinical success was defined as successful non-operative management and splenic salvage on follow-up. RESULTS 138 patients were included of which 68.1% were male. The median age was 47 years (interquartile range (IQR) = 32.5 years). The most common mechanisms of injury were motor vehicle accidents (37.0%), mechanical falls (25.4%), and pedestrians hit by motor vehicles (10.9%). 70.3% of patients had American Association for the Surgery of Trauma (AAST) grade 4 injuries. Patients were treated with proximal SAE (n = 97), distal SAE (n = 23) or combined SAE (n = 18), and 68% were embolized with an Amplatzer plug. No significant differences were observed across all measures of hospitalization (Length of hospital stay: x2(2) = .358, P = .836; intensive care unit (ICU) stay: x2(2) = .390, P = .823; ICU stay post-procedure: x2(2) = 1.048, P = .592). Technical success and splenic salvage were achieved in 100% and 97.8% of patients, respectively. 7 patients (5%) had post-embolization complications and 7 patients (5%) died during hospital admission, but death was secondary to other injuries sustained in the trauma rather than complications related to splenic injury or its management. CONCLUSION We report that SAE as an adjunct to non-operative management of blunt splenic trauma can be performed safely and effectively with a high rate of clinical success.

Abstract
BACKGROUND True visceral artery aneurysms are potentially complex to treat but with advances in technology and increasing interventional radiology expertise over the past decade are now increasingly the domain of the interventional radiologist. BODY: The interventional approach is based on localization of the aneurysm and identification of the anatomical determinants to treat these lesions to prevent aneurysm rupture. Several different endovascular techniques are available and should be selected carefully, dependent on the aneurysm morphology. Standard endovascular treatment options include stent-graft placement and trans-arterial embolisation. Different strategies are divided into parent artery preservation and parent artery sacrifice techniques. Endovascular device innovations now include multilayer flow-diverting stents, double-layer micromesh stents, double-lumen balloons and microvascular plugs and are also associated with high rates of technical success. CONCLUSION Complex techniques such as stent-assisted coiling and balloon-remodeling techniques are useful techniques and require advanced embolisation skills and are further described.

Abstract
Amyloidosis is a term describing the extracellular deposit of fibrils composed of subunits of several different normal serum proteins in various tissues. Amyloid light chain (AL) amyloidosis contains fibrils that are composed of fragments of monoclonal light chains. Many different disorders and conditions can lead to spontaneous splenic rupture, including AL amyloidosis. We present a case of a 64-year-old woman with spontaneous splenic rupture and hemorrhage. A final diagnosis of systemic amyloidosis secondary to plasma cell myeloma was made with infiltrative cardiomyopathy and possible diastolic congestive heart failure exacerbation. We also provide a narrative review of all documented cases of splenic rupture associated with amyloidosis from the year 2000 until January 2023, along with the main clinical findings and management strategies.

Abstract
The spleen is the most commonly injured organ in blunt abdominal trauma. Its management depends on hemodynamic stability. According to the American Association for the Surgery of Trauma-Organ Injury Scale (AAST-OIS ≥ 3), stable patients with high-grade splenic injuries may benefit from preventive proximal splenic artery embolization (PPSAE). This ancillary study, using the SPLASH multicenter randomized prospective cohort, evaluated the feasibility, safety, and efficacy of PPSAE in patients with high-grade blunt splenic trauma without vascular anomaly on the initial CT scan. All patients included were over 18 years old, had high-grade splenic trauma (≥AAST-OIS 3 + hemoperitoneum) without vascular anomaly on the initial CT scan, received PPSAE, and had a CT scan at one month. Technical aspects, efficacy, and one-month splenic salvage were studied. Fifty-seven patients were reviewed. Technical efficacy was 94% with only four proximal embolization failures due to distal coil migration. Six patients (10.5%) underwent combined embolization (distal + proximal) due to active bleeding or focal arterial anomaly discovered during embolization. The mean procedure time was 56.5 min (SD = 38.1 min). Embolization was performed with an Amplatzer™ vascular plug in 28 patients (49.1%), a Penumbra occlusion device in 18 patients (31.6%), and microcoils in 11 patients (19.3%). There were two hematomas (3.5%) at the puncture site without clinical consequences. There were no rescue splenectomies. Two patients were re-embolized, one on Day 6 for an active leak and one on Day 30 for a secondary aneurysm. Primary clinical efficacy was, therefore, 96%. There were no splenic abscesses or pancreatic necroses. The splenic salvage rate on Day 30 was 94%, while only three patients (5.2%) had less than 50% vascularized splenic parenchyma. PPSAE is a rapid, efficient, and safe procedure that can prevent splenectomy in high-grade spleen trauma (AAST-OIS) ≥ 3 with high splenic salvage rates.

Therapeutic strategies for pseudoaneurysm following blunt liver and spleen injuries: A multicenter cohort study in the pediatric population. J Trauma Acute Care Surg 2023; 94:433-442.

Abstract
BACKGROUND Little guidance exists for the treatment of pseudoaneurysm (PA) following pediatric blunt liver and/or spleen injuries (BLSIs). We aimed to describe the incidence of delayed PA development and the subsequent clinical course of PA in pediatric BLSIs. METHODS This multicenter retrospective cohort study from Japan included pediatric patients (16 years and younger) who sustained BLSIs from 2008 to 2019. The cohort was divided into four groups based on hemostatic intervention within 48 hours of admission, namely, nonoperative management (NOM), NOM with interventional radiology (IR), operative management (OM), and combined IR/OM. Descriptive statistics were used to describe the incidence of delayed PA among the groups and to characterize the clinical course of any PAs. RESULTS A total of 1,407 children (median age, 9 years) from 83 institutions were included. The overall number (incidence) of cases of delayed PA formation was 80 (5.7%), and the number with delayed PA rupture was 16 cases (1.1%) in the entire cohort. Patients treated with NOM (1,056), NOM with IR (276), OM (53), and combined IR/OM (22) developed 43 (4.1%), 32 (12%), 2 (3.8%), and 3 (14%) delayed PAs, respectively. Among patients who developed any PAs, 39% of patients underwent prophylactic IR for unruptured PA, while 13% required emergency angioembolization for delayed PA rupture, with one ruptured case requiring total splenectomy. At least 45% of patients experienced spontaneous resolution of PA without any interventions. CONCLUSION Our results suggest that the risk of delayed PA still exists even after acute phase IR as an adjunct to NOM for BLSIs in children, indicating the necessity of a period of further observation. While endovascular interventions are usually successful for PA management, including rupture cases, given the high incidence of spontaneous resolution, the ideal management of PA remains to be investigated in future studies. LEVEL OF EVIDENCE Therapeutic/Care Management; Level IV.

Splenic Artery Embolization for Unstable Patients with Splenic Injury: A Retrospective Cohort Study. J Vasc Interv Radiol 2023; 34:86-93. [PMID: 36244633 DOI: 10.1016/j.jvir.2022.10.014] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/16/2022] [Revised: 08/26/2022] [Accepted: 10/05/2022] [Indexed: 11/06/2022] Open
Abstract
PURPOSE To compare the outcomes of splenic artery embolization (SAE) for acute splenic injury (ASI) between patients who are hemodynamically stable (HDS) and hemodynamically unstable (HDU). Nonoperative management with SAE has become an accepted practice for patients who are HDS with ASI; however, SAE for the treatment of patients who are HDU with ASI has not been well studied. MATERIALS AND METHODS A retrospective cohort study was performed, including 52 patients who were HDU and HDS who underwent SAE for ASI at a Level 1 trauma center. HDU was defined as the lowest recorded systolic blood pressure prior to intervention <90 mm Hg. Utilizing the American Association for Surgery of Trauma (AAST) splenic injury scale, AAST Grades 1-3 were defined as low grade, and Grades 4-5 were defined as high grade. The primary outcomes were survival at 30 days and the need for subsequent splenectomy. RESULTS Seventy-five percent (n = 39) of the patients were HDS, and 25% (n = 13) were HDU. The majority (69%) of patients who were HDU who underwent SAE did not require splenectomy, compared with 95% of patients who were HDS (P = .03). No significant difference in 30-day survival between patients who were HDU and HDS was noted. No major adverse events were recorded. There was no significant difference in 30-day patient survival or the rate of subsequent splenectomy between high-grade and low-grade splenic injuries. CONCLUSIONS In this retrospective cohort study, there was no statistically significant difference in the adverse events or 30-day post-SAE survival rates between patients who were HDS and HDU with ASI. The authors conclude that SAE can be a safe and effective treatment option for patients who are HDU with ASI, including high-grade splenic injury.

Abstract
We present the case of a female patient in her 40s who underwent a splenic artery aneurysm (SAA) repair following a previous laparoscopic sleeve gastrectomy (SG). We aim to discuss the management approach to SAAs and considerations in the setting of previous bariatric surgery.The patient consented to this case report. We include preoperative and postoperative radiological images and intraoperative images.While pseudoaneurysms following bariatric surgery have been reported, we present a case of a likely true SAA following SG. Our experience may assist others who come across similar cases in the future.

Abstract
Background Proximal splenic artery embolisation (PSAE) can be performed in stable patients with Association for the Surgery of Trauma (AAST) grade III-V splenic injury. PSAE reduces splenic perfusion but maintains viability of the spleen and pancreas via the collateral circulation. The hypothesized ideal location is between the dorsal pancreatic artery (DPA) and great pancreatic artery (GPA). This study compares the outcomes resulting from PSAE embolisation in different locations along the splenic artery. Materials and methods Retrospective review was performed of PSAE for blunt splenic trauma (2015–2020). Embolisation locations were divided into: Type I, proximal to DPA; Type II, DPA-GPA; Type III, distal to GPA. Fifty-eight patients underwent 59 PSAE: Type I (7); Type II (27); Type III (25). Data was collected on technical and clinical success, post-embolisation pancreatitis and splenic perfusion. Statistical significance was assessed using a chi-squared test. Results Technical success was achieved in 100% of cases. Clinical success was 100% for Type I/II embolisation and 88% for Type III: one patient underwent reintervention and two had splenectomies for ongoing instability. Clinical success was significantly higher in Type II embolisation compared to Type III (p = 0.02). No episodes of pancreatitis occurred post-embolisation. Where post-procedural imaging was obtained, splenic perfusion remained 100% in Type I and II embolisation and 94% in Type III. Splenic perfusion was significantly higher in the theorized ideal Type II group compared to Type I and III combined (p = 0.01). Conclusion The results support the proposed optimal embolisation location as being between the DPA and GPA.

Abstract
Background Upper gastrointestinal, non-variceal haemorrhage can be related to various etiologies, including peptic ulcer, neoplasm, gastritis, Dieulafoy lesions and other, rare underlying diseases. Here, we describe another, yet unreported etiology of gastric bleeding. Case presentation A 49-year-old man presented with melena; gastroscopy revealed blood in the stomach without active bleeding source. Computed tomography angiography demonstrated a cluster of enlarged gastrosplenic arterial collaterals in the gastric wall and coils in the splenic artery, related to an embolization procedure 30-years ago for splenic trauma. Definitive treatment included catheter-directed glue embolization of the left gastric artery and the enlarged gastrosplenic collaterals. The postinterventional course was uneventful and no recurrence of upper gastrointestinal bleeding was noted after 6 months of follow-up. Conclusions Upper gastrointestinal bleeding associated with eroded gastrosplenic collaterals, related to previous splenic artery embolization, can be successfully treated with glue-embolization.

Abstract
Babesiosis incidence in the United States has been increasing with an 11% rise between 2018 and 2019 based on the latest CDC annual summary, reaching its highest ever reported incidence. This primarily tick-borne disease is particularly prevalent in New England. Despite predominantly nonspecific and at times subtle symptoms, life-threatening complications do occur. One such complication is splenic rupture which has been suggested to be more common in younger and otherwise healthy individuals. This is a report on a successful splenic artery embolization in a 65-year-old male from upstate New York who, unlike most prior studies, showed splenic rupture after he was discharged with negative parasitemia and general improvement following several days of targeted antibiotic therapy. Increased incidence and various presentations of Babesiosis call for an attempt to promote clinical awareness for radiologists among other specialties.

Abstract
PURPOSE While interventional radiologists occupy a critical role in adult trauma management, the role of interventionalist in pediatric trauma continues to evolve. The indications for transarterial embolization (TAE) are significantly different in pediatric patients in whom non-operative management (NOM) has a much more prominent role than in adults. Contrast extravasation on imaging may not require acute surgical or interventional management as it would in an adult. There are also areas in which pediatric interventional radiology is increasingly useful such as pelvic TAE in failed management, or splenic embolization to treat bleeding without the loss of splenic function inherent to surgical splenectomy. The rapid evolution of techniques and devices in pediatric patients is also changing what interventions are possible in pediatric trauma management which necessitates frequent reassessment of the guidelines and interventional radiology's role in caring for these patients. CONCLUSION This review seeks to consolidate the recent literature to describe the evolving role of the interventional radiologist in pediatric trauma management.

Splenic artery embolization improves outcomes and decreases the length of stay in hemodynamically stable blunt splenic injuries - A level 1 Australian Trauma centre experience. Injury 2022; 53:1620-1626.

Abstract
BACKGROUND Splenic injuries are the most common visceral injury following blunt abdominal trauma. Increasingly, non-operative management (NOM) and the use of adjunctive splenic angioembolization (ASE) is favoured over operative management (OM) for the hemodynamically stable patient. However, clinical predictors for successful NOM, particularly the role of ASE as an adjunct, remain poorly defined. This study aims to evaluate the outcomes of patients undergoing ASE vs NOM. METHODS A retrospective clinical audit was performed of all patients admitted with blunt splenic injury (BSI) from January 2005 to January 2018 at the Royal Adelaide Hospital. The primary outcome was ASE or NOM failure rate. Secondary outcomes were grade of splenic injury, Injury Severity Score (ISS), length of hospital stay (LOS), and delayed OM or re-angioembolization rates. RESULTS Of 208 patients with BSI, 60 (29%) underwent OM, 54 (26%) ASE, and 94 (45%) NOM only. Patients were predominantly male 165 (79%), with a median age of 33 (IQR 24-51) years. The median ISS was 29 (20-38). There was no difference in the overall success rates for each modality of primary management (48 (89%) ASE vs 77 (82%) NOM, p = 0.374), though patients managed with ASE were older (38 vs 30 years, p = 0.029), had higher grade of splenic injury (grade ≥ IV 42 (78%) vs 8 (8.5%), p<0.001), with increased rates of haemo-peritoneum (46 (85%) vs 51 (54%), p<0.001) and contrast blush (42 (78%) vs 2 (2%), p<0.001). However, for grade III splenic injury, patients managed with ASE had a trend towards better outcome with no failures when compared to the NOM group (0 (0%) vs 8 (35%), p = 0.070) with a significant reduction in LOS (7.2 vs 10.8 days, p = 0.042). Furthermore, the ASE group overall had a significantly shorter LOS compared to the NOM group (10.0 vs 16.0 days, p<0.001). CONCLUSION ASE as an adjunct to NOM significantly reduces the length of stay in BSI patients and is most successful in managing AAST grade III injuries.

Abstract
Splenic artery pseudoaneurysm (PSA) is a contained vascular wall lesion associated with a high mortality rate, generally related to pancreatitis, trauma, malignancy, iatrogenic injury, and segmental arterial mediolysis. Computed tomography angiography allows us to visualize the vascular anatomy, differentiate a PSA from an aneurysm, and provide adequate information for endovascular/surgical treatment. The present review reports on the main state-of-the-art splenic artery PSA diagnosis, differentiating between the pros and cons of the imaging methods and about the endovascular treatment.

Abstract
Introduction: Evaluate outcomes and radiation exposure across different splenic artery embolization (SAE) techniques for splenic injuries secondary to blunt trauma. Methods: This retrospective cohort study included patients 18 years of age or older who underwent SAE for splenic injury after blunt trauma from January 2011 to June 2019. Results: Sixty patients underwent angiography for splenic injury after blunt traumatic injury. Forty-four patients were embolized. Seventeen patients underwent proximal SAE, and 23 underwent distal SAE. Four patients had a combination of proximal and distal SAE. Eleven patients had subsequent major complications requiring splenectomy. There was no significant difference in major complication rate when comparing proximal SAE 29.4% versus distal SAE 21.7%. No significant difference was noted across the two groups with respect to age or grade of injury. There was a statistically significant difference (P = 0.004) in fluoroscopy time between the proximal 10.1 ± 4.2 min and distal group 17.8 ± 8.7 min. No statically significant difference was found in major complications when comparing coil versus gel foam embolization. Conclusion: Proximal SAE is associated with a significantly lower fluoroscopy time (P = 0.004). Complication rates are similar after proximal and distal SAE. No significant difference was found in major complication rates comparing coil versus gel foam embolization. Minor complications more commonly occurred after proximal embolization with gel-foam.

Abstract
PURPOSE Splenic artery pseudoaneurysms (PSA) are relatively rare but associated with high mortality/morbidity when presenting acutely. Embolization has emerged as the treatment of choice. We aim to evaluate the outcomes of embolization for the treatment of splenic artery PSAs. METHODS From 2007 to 2019, all patients that underwent embolization for splenic artery PSAs were included in this IRB-approved review. Evaluated outcomes included complications, morbidity/mortality rates, and 30-day white blood cell count. Student t-tests were performed to compare laboratory values before and after embolization. 5-year survival rates were estimated using Kaplan Meier methodology. RESULTS A retrospective analysis of 24 patients (14 males, mean age 51 ± 19 years) who underwent splenic artery PSA embolization was performed. Fifteen PSA embolizations were performed in an emergent setting. There was technical success in 23/24 patients. Etiologies included trauma (10), pancreatitis (9), post-surgical (3), and malignancy (2). Post-embolization patients had a mean length of stay of 19 days and within 30 days, 9 patients developed leukocytosis (median of 14,800/μl). The 5-year survival rate of these patients was 89% [95% CI 75% - 100%]. Post-procedure, 4 patients developed grade 2 complications. Grade 3 complications were observed in 5 patients. One (4.2%) splenic abscess was identified. Of the 19 patients with follow-up imaging, 14 patients had splenic infarcts (5 infarcts were >50% of splenic volume). CONCLUSIONS Splenic artery PSAs are encountered in the emergent setting and are most frequently secondary to trauma or pancreatitis. Embolization can be life-saving in these critically ill patients.

Abstract
Introduction Splenic artery embolization (SAE) has been shown to be safe and effective for non-operative management of patients with splenic trauma while preserving splenic function. A variety of coils, plugs, particles and liquid embolics have all been used. NBCA (n-butyl cyanoacrylate) is used less frequently than other modalities but is effective. Methods A retrospective review of all patients who underwent SAE with NBCA for blunt abdominal trauma at a single tertiary medical center over a six-year period. Results Out of 123 SAE patients, 7 utilized NBCA; 6 patients had intraparenchymal splenic artery pseudoaneurysms, 2 had intraparenchymal arteriovenous fistulas, and 5 had active extravasation from the spleen on CT imaging. There was 100% technical success rate. There were no acute post-op complications or complications at 30-day and 90-day follow up. One patient died 2 days following SAE secondary to worsening subdural hematoma unrelated to SAE. Conclusions NBCA is safe and effective in treating patients with splenic injury particularly in patients with high grade splenic injury demonstrating extensive intraparenchymal vascular injury and/or intraprocedural extravasation in distal locations.

Abstract
The spleen is a commonly injured organ in blunt abdominal trauma. Splenic preservation, however, is important for immune function and prevention of overwhelming infection from encapsulated organisms. Splenic artery embolization (SAE) for high-grade splenic injury has, therefore, increasingly become an important component of non-operative management (NOM). SAE decreases the blood pressure to the spleen to allow healing, but preserves splenic perfusion via robust collateral pathways. SAE can be performed proximally in the main splenic artery, more distally in specific injured branches, or a combination of both proximal and distal embolization. No definitive evidence from available data supports benefits of one strategy over the other. Particles, coils and vascular plugs are the major embolic agents used. Incorporation of SAE in the management of blunt splenic trauma has significantly improved success rates of NOM and spleen salvage. Failure rates generally increase with higher injury severity grades; however, current management results in overall spleen salvage rates of over 85%. Complication rates are low, and primarily consist of rebleeding, parenchymal infarction or abscess. Splenic immune function is felt to be preserved after embolization with no guidelines for prophylactic vaccination against encapsulated bacteria; however, a complete understanding of post-embolization immune changes remains an area in need of further investigation. This review describes the history of SAE from its inception to its current role and indications in the management of splenic trauma. The endovascular approach, technical details, and outcomes are described with relevant examples. SAE is has become an important part of a multidisciplinary strategy for management of complex trauma patients.

Abstract
Importance Splenic arterial embolization (SAE) improves the rate of spleen rescue, yet the advantage of prophylactic SAE (pSAE) compared with surveillance and then embolization only if necessary (SURV) for patients at high risk of spleen rupture remains controversial. Objective To determine whether the 1-month spleen salvage rate is better after pSAE or SURV. Design, Setting, and Participants In this randomized clinical trial conducted between February 6, 2014, and September 1, 2017, at 16 institutions in France, 133 patients with splenic trauma at high risk of rupture were randomized to undergo pSAE or SURV. All analyses were performed on a per-protocol basis, as well as an intention-to-treat analysis for specific events. Interventions Prophylactic SAE, preferably using an arterial approach via the femoral artery, or SURV. Main Outcomes and Measures The primary end point was an intact spleen or a spleen with at least 50% vascularized parenchyma detected on an arterial computed tomography scan at 1 month after trauma, assessed by senior radiologists masked to the treatment group. Secondary end points included splenectomy and pseudoaneurysm, secondary SAE after inclusion, complications, length of hospital stay, quality-of-life score, and length of time off work or studies during the 6-month follow-up. Results A total of 140 patients were randomized, and 133 (105 men [78.9%]; median age, 30 years [interquartile range, 23-47 years]) were retained in the study. For the primary end point, data from 117 patients (57 who underwent pSAE and 60 who underwent SURV) could be analyzed. The number of patients with at least a 50% viable spleen detected on a computed tomography scan at month 1 was not significantly different between the pSAE and SURV groups (56 of 57 [98.2%] vs 56 of 60 [93.3%]; difference, 4.9%; 95% CI, -2.4% to 12.1%; P = .37). By the day 5 visit, there were significantly fewer splenic pseudoaneurysms among patients in the pSAE group than in the SURV group (1 of 65 [1.5%] vs 8 of 65 [12.3%]; difference, -10.8%; 95% CI, -19.3% to -2.1%; P = .03), significantly fewer secondary embolizations among patients in the pSAE group than in the SURV group (1 of 65 [1.5%] vs 19 of 65 [29.2%]; difference, -27.7%; 95% CI, -41.0% to -15.9%; P < .001), and no difference in the overall complication rate between the pSAE and SURV groups (19 of 65 [29.2%] vs 27 of 65 [41.5%]; difference, -12.3%; 95% CI, -28.3% to 4.4%; P = .14). Between the day 5 and month 1 visits, the overall complication rate was not significantly different between the pSAE and SURV groups (11 of 59 [18.6%] vs 12 of 63 [19.0%]; difference, -0.4%; 95% CI, -14.4% to 13.6%; P = .96). The median length of hospitalization was significantly shorter for patients in the pSAE group than for those in the SURV group (9 days [interquartile range, 6-14 days] vs 13 days [interquartile range, 9-17 days]; P = .002). Conclusions and Relevance Among patients with splenic trauma at high risk of rupture, the 1-month spleen salvage rate was not statistically different between patients undergoing pSAE compared with those receiving SURV. In view of the high proportion of patients in the SURV group needing SAE, both strategies appear defendable. Trial Registration ClinicalTrials.gov Identifier: NCT02021396.

Abstract
INTRODUCTION To compare the outcomes of proximal (pSAE) versus distal (dSAE) splenic artery embolisation for management of focal distal arterial splenic injuries secondary to blunt splenic trauma. METHOD Ethical approval was granted by the hospital research and ethics committee, Project 389/19. All patients who underwent splenic artery embolisation secondary to blunt abdominal trauma from 1 January 2009 to 1 January 2019 were reviewed. Patients with a tandem embolisation (both proximal and distal embolisations) or those with no acute vascular injury on angiography were excluded. Patient demographics, injury type/ AAST grade (2018 classification), technique of embolisation and outcomes were collected. Complications and splenectomy rates up to 30 days were recorded. RESULTS 136 out of 232 patients had an embolisation performed for a distal vascular injury including active arterial bleeding, pseudoaneurysm or arteriovenous fistula. Mean age was 41 (range 16-84). Mean AAST grade was 4 (range 3-5). Mean Injury Severity Score was 22. pSAE was performed in 79.4% (n = 108) and dSAE in 20.6% (n = 28). Major complications occurred in 12 patients (pSAE n = 12, 11.1%; dSAE n = 0, P > 0.05); 6 pSAE required splenectomy (n = 6, 5.6%). There was no significant difference in outcomes between the two groups or when based on AAST grading. CONCLUSION No significant difference was observed between proximal and distal embolisation techniques for blunt trauma patients with a distal vascular injury in terms of technical and clinical success.

A pilot randomized controlled trial of endovascular coils and vascular plugs for proximal splenic artery embolization in high-grade splenic trauma. Abdom Radiol (NY) 2021; 46:2823-2832.

Abstract
PURPOSE To evaluate the feasibility of enrolling patients in a randomized controlled trial (RCT) comparing endovascular coils (EC) and vascular plugs (VP) for proximal splenic artery embolization (pSAE) in high-grade splenic trauma, and to collect data to inform the design of a larger clinical effectiveness trial. METHODS Single-center, prospective, RCT of patients with Grade III-V splenic injuries selected for nonoperative management. Patients were randomized to pSAE with EC or VP. The main outcome was feasibility. We also evaluated technical success, time to stasis, complications, mortality, and splenectomy rates, by estimating rates and 95% confidence intervals. RESULTS 46 of 50 eligible patients were enrolled (92%, 95% CI 90-100%). Overall, splenic salvage was 98% (45/46; 95% CI 94-100%). Primary technical success was observed in 22 EC patients (96%; 95% CI 87-100%) and 20 VP patients (87%; 95% CI 73-100%). Bayesian analysis suggests a > 80% probability that primary technical success is higher for EC. Two complications (one major and one minor) occurred in the EC group (9%; CI 0-20%) and one major complication occurred in the VP group (4%; CI 0-13%). CONCLUSIONS Randomized comparisons of endovascular devices used for pSAE after trauma are feasible. pSAE using either EC or VP results in excellent rates of splenic salvage in trauma patients with high-grade splenic injuries. These high rates of splenic salvage and low rates of complications make their use as a primary outcome in a future trial problematic. Consideration should be given to technical parameters as a primary outcome for future trials.

Abstract
INTRODUCTION Splenic injury is common in blunt trauma. We sought to evaluate the injury characteristics and outcomes of BSI admitted over a 10-y period to an academic trauma center. METHODS A retrospective review of adult blunt splenic injury patients admitted between January 2009 and September 2018. RESULTS The 423 patients meeting inclusion criteria were divided by management: Observational (OBS, n = 261), splenic surgery (n = 114 including 4 splenorrhaphy patients), SAE (n = 43), and multiple treatment modalities (3 had SAE followed by surgery and 2 OBS patients underwent splenic surgery at readmission). The most common mechanism of injury was motor vehicle collision (47.8%). The median ISS (OBS 17, SAE 22, Surgery 34) and spleen AIS (OBS 2, SAE 3, Surgery 4) were significantly different. Complication rates (OBS 21.8%, SAE 9.3%, Surgery 45.6%) rates were significantly different, but mortality (OBS 7.3%, SAE 2.3%, Surgery 13.2%), discharge to home and readmission rates were not. Additional abdominal injuries were identified in 26.3% of the surgery group and 2.7% of OBS group. SAE rate increased from 3.0% to 28%; median spleen AIS remained 2-3. Thirty-five patients expired; 28 had severe head, chest, and/or extremity injuries (AIS ≥4). CONCLUSION SAE rates increased over time. Splenorrhaphy rates were low. SAE was associated with relatively low rates of mortality and complications in appropriately selected patients.

Abstract
Background Massive bleeding is a major preventable cause of early death in trauma. It often requires surgical and/or endovascular intervention. We aimed to describe the utilization of angioembolization in patients with abdominal and pelvic traumatic bleeding at a level 1 trauma center. Methods We conducted a retrospective analysis for all trauma patients who underwent angioembolization post-traumatic bleeding between January 2012 and April 2018. Patients’ data and details of injuries, angiography procedures and outcomes were extracted from the Qatar national trauma registry. Results A total of 175 trauma patients underwent angioembolization during the study period (103 for solid organ injury, 51 for pelvic injury and 21 for other injuries). The majority were young males. The main cause of injury was blunt trauma in 95.4% of the patients. The most common indication of angioembolization was evident active bleeding on the initial CT scan (contrast pool or blushes). Blood transfusion was needed in two-third of patients. The hepatic injury cases had higher ISS, higher shock index and more blood transfusion. Absorbable particles (Gelfoam) were the most commonly used embolic material. The overall technical and clinical success rate was 93.7% and 95%, respectively, with low rebleeding and complication rates. The hospital and ICU length of stay were 13 and 6 days, respectively. The median injury to intervention time was 320 min while hospital arrival to intervention time was 274 min. The median follow-up time was 215 days. The overall cohort mortality was 15%. Conclusion Angioembolization is an effective intervention to stop bleeding and support nonoperative management for both solid organ injuries and pelvic trauma. It has a high success rate with a careful selection and proper implementation.

Abstract
Iatrogenic splenic injury is a rare complication of all abdominal surgeries. Despite the procedure's overall safety, colonoscopy is now the procedure most frequently associated with iatrogenic splenic injury. A 58-year-old male with a past medical history of hypertension, lung cancer in remission, colon polyps, and severe scoliosis presented for grade three splenic laceration two days following a routine colonoscopy. He had no recent history of injury or other inciting events that could have led to traumatic injury. Non-operative management included splenic artery embolization and transfusion of one unit of packed red blood cells, after which he improved in the hospital and was discharged home in stable condition. This case postulates the possible influence of his severe scoliosis, and thus altered abdominal viscera anatomy, on his iatrogenic splenic injury, as well as the potential importance of investigating scoliosis as a risk factor for difficult colonoscopy or even iatrogenic splenic injury during colonoscopy.

Abstract
BACKGROUND As an adjunct to non-operative management, splenic artery embolization (SAE) has been increasingly utilized throughout the world and is now the standard of care for hemodynamically stable patients. This study aimed to retrospectively assess the rate of splenic salvage and complications after SAE for blunt trauma at a level 1 trauma center using the 2018 update to the AAST criteria, and further sub-stratify the role of angiography in AAST grade III injuries with significant hemoperitoneum. All patients between 1 January 2009 and 1 January 2019 who underwent blunt trauma and proceeded to embolization were included. Data was collected concerning initial injury grade, location of embolization, type of embolic material used, complications, and need for subsequent splenectomy. Technical success was defined as successful angiographic occlusion of the target artery at the conclusion of embolization. Clinical success was defined as splenic salvage at discharge. Vascular lesions were characterized including those with active bleeding, pseudoaneurysm, and arterio-venous fistula. RESULTS Two hundred thirty-two patients were included in the study. Treatments were performed at a median of 0 days (range 0-28 days) and the median AAST grade was IV (range III-V). Technical success was achieved in all patients. There were 13 complications (5.6%) consisting of re-bleed (9, 3.9%), infarction (3, 1.3%), and access site haematoma (1, 0.43%). Clinical success was achieved in 97% of patients with 7 patients requiring splenectomy after SAE (3.0%) at a median time of 4 days (range 0-17 days). Angiography in patients with grade III injuries identified 18 occult vascular injuries not identified at initial CT (p < 0.0001). CONCLUSIONS The SPLEEN-IN study shows that treatment of intermediate-high grade blunt force traumatic splenic injuries using SAE resulted in a low rate of complication and splenic salvage in 97% of patients, providing a safe and effective treatment in stable patients. In addition, angiography of grade III injuries identified occult vascular lesions and may warrant treatment of select patients in this cohort. LEVEL OF EVIDENCE Level 3.

Abstract
The spleen is a commonly injured organ and the splenic vasculature is also susceptible to inflammation and trauma, often resulting in aneurysm formation. Splenic artery aneurysms carry a high risk of rupture and are associated with high mortality and morbidity. Due to the advances in endovascular techniques and devices, endovascular management of splenic vascular pathologies is now considered a first-line strategy. Endovascular embolisation and advance techniques including balloon- or stent-assisted coil embolisation enables minimally invasive management option while preserving splenic function.

Abstract
Good knowledge of the various approaches of embolization of peripheral bleedings and different embolic materials available is of paramount importance for successful and safe embolization. We review and illustrate the main endovascular and percutaneous techniques used for embolization, along with the characteristics of the different embolic materials, and the potential complications.

Abstract
Persistent eating of non-nutritive, nonfood substances (Pica) is seen in children and adult patients with psychiatric problems. Ingestion of multiple metallic FBs with resultant bezoar formation is rare. While many FBs are passed without complication, mucosal injury, bleeding, obstruction or perforation can occur in some cases. Endoscopic FB removal is performed in 20% of patients following FB ingestion. Generally, these are safe procedures, and very effective in extracting ingested FBs. We report, a 25-year-old male patient with a metal ingestion predominant Pica, requiring multiple prior extraction procedures (including open gastrostomy). He developed a splenic artery pseudoaneurysm following his latest endoscopic FB removal, that was successfully treated with transarterial coil embolization. The unique circumstances leading to this rare complication and its successful endovascular management make this case worthy of report.
