RESUMO
INTRODUCTION: Venous thromboembolism (VTE) continues to be a major cause of morbidity in trauma. It is unclear whether the type of hemorrhage control procedure (i.e., splenectomy versus angioembolization) is associated with an increased risk of VTE. We hypothesize that hemodynamically stable patients undergoing angioembolization for blunt high-grade splenic injuries have lower rates of VTE compared to those undergoing splenectomy. METHODS: The American College of Surgeons Trauma Quality Program dataset from 2017 to 2019 was queried to identify all patients with American Association for the Surgery of Trauma grade 3-5 blunt splenic injuries. Outcomes including VTE rates were compared between those who were managed with splenectomy versus angioembolization. Propensity score matching (1:1) was performed adjusting for age, sex, initial vital signs, Injury Severity Score, and splenic injury grade. RESULTS: The analysis included 4698 matched patients (splenectomy [n = 2349] and angioembolization [n = 2349]). The median (interquartile range) age was 41 (27-58) years and 69% were male. Patients were well matched between groups. Angioembolization was associated with significantly lower VTE than splenectomy (2.2% versus 3.4%, P = 0.010) despite less use of VTE chemoprophylaxis (70% versus 80%, P < 0.001), as well as a relative delay in initiation of chemoprophylaxis (44 h versus 33 h, P < 0.001). Hospital and intensive care unit length of stay and mortality were also significantly lower in the angioembolization group. CONCLUSIONS: Angioembolization is associated with a significantly lower incidence of VTE than splenectomy. Thus, angioembolization should be considered for initial management of hemodynamically stable patients with high-grade blunt splenic injuries in whom laparotomy is not otherwise indicated.

INTRODUCTION: While nonoperative management has become widely accepted, whether nonoperative management of blunt splenic trauma is standardized across pediatric trauma centers and different racial groups warrants further investigation. Using the National Trauma Database, the purpose of this study was to quantify the differences in the management of pediatric splenic trauma across different pediatric trauma centers, with respect to injury severity, race, ethnicity, and insurance. METHODS: Patients under 20 y of age with blunt splenic trauma reported to the 2018 and 2019 National Trauma Data Bank were identified. Primary outcomes were splenectomy, embolization, transfusion, mortality, injury severity score (ISS), and length of hospital stay (LOS) and length of intensive care unit stay. Continuous data and categorical data were analyzed using ANOVA and Chi-squared test, respectively. Nearest 1:1 neighbor matching was performed between minority patients and White patients. P < 0.05 for all comparative analyses was considered statistically significant. RESULTS: Of the total cohort (n = 1919), 70.3% identified as White, while 21.6% identified as Black or Hispanic. The mortality rate was 0.3%. Among different race categories, the frequency of spleen embolization (P = 0.99), splenectomy (P = 0.99), blood transfusion (P = 1), and mortality (P = 1), were not significantly different. After controlling for ISS and age with propensity score matching, the mean hospital LOS remained significantly higher in minority patients, with a mean of 5.44 d compared to 4.72 d (P = 0.05). Mean length of intensive care unit stay was not significantly different after propensity matching, with a mean of 1.79 d and 1.56 spent in the ICU for minority and White patients respectively (P = 0.17). While propensity score matching preserved statistical significance, the ISS for the minority group remained 1.12 times higher than the ISS of the Caucasian group. There was no statistically significant difference among races with respect to different payment methods and insurance status, although Black and Hispanic patients were proportionally underinsured. CONCLUSIONS: While minority patients had a relatively higher number of operative interventions and longer hospital and ICU stays, after propensity score matching, mean ISS remained higher in the minority group. Our findings suggest that injury severity is likely to influence the difference in LOS between the two groups. Furthermore, our data highlight how nonoperative management is not standardized across pediatric trauma centers.

INTRODUCTION: This study aims to compare the outcomes of splenic artery embolization (SAE) versus splenectomy in adult trauma patients with high-grade blunt splenic injuries. METHODS: This retrospective analysis of the American College of Surgeons Trauma Quality Improvement Program database (2017-2021) compared SAE versus splenectomy in adults with blunt high-grade splenic injuries (grade ≥ IV). Patients were stratified first by hemodynamic status then splenic injury grade. Outcomes included in-hospital mortality, intensive care unit length of stay (ICU-LOS), and transfusion requirements at four and 24 h from arrival. RESULTS: Three thousand one hundred nine hemodynamically stable patients were analyzed, with 2975 (95.7%) undergoing splenectomy and 134 (4.3%) with SAE. One thousand eight hundred sixty five patients had grade IV splenic injuries, and 1244 had grade V. Patients managed with SAE had 72% lower odds of in-hospital mortality (odds ratio [OR] 0.28; P = 0.002), significantly shorter ICU-LOS (7 versus 9 d, 95%, P = 0.028), and received a mean of 1606 mL less packed red blood cells at four h compared to those undergoing splenectomy. Patients with grade IV or V injuries both had significantly lower odds of mortality (IV: OR 0.153, P < 0.001; V: OR 0.365, P = 0.041) and were given less packed red blood cells within four h when treated with SAE (2056 mL versus 405 mL, P < 0.001). CONCLUSIONS: SAE may be a safer and more effective management approach for hemodynamically stable adult trauma patients with high-grade blunt splenic injuries, as demonstrated by its association with significantly lower rates of in-hospital mortality, shorter ICU-LOS, and lower transfusion requirements compared to splenectomy.

BACKGROUND: In the early 2000s, substantial variations were reported in the management of pediatric patients with blunt splenic injury (BSI). The purpose of this study was to assess the recent trends and disparities between different types of trauma centers. We hypothesized that there would be persistent disparities despite decreased trends in the rate of splenectomy. METHODS: This is a retrospective cohort study using the American College of Surgeons Trauma Quality Improvement Program database. We included patients (age ≤18 years) with high-grade BSI (Abbreviated Injury Scale 3-5) between 2014 and 2021. The patients were divided into three groups based on trauma center types (adult trauma centers [ATCs], mixed trauma centers [MTCs], and pediatric trauma centers [PTCs]). The primary outcome was the splenectomy rate. Logistic regression was performed to evaluate the association between trauma center types and clinical outcomes. Additionally, the trends in the rate of splenectomy at ATCs, MTCs, and PTCs were evaluated. RESULTS: A total of 6601 patients with high-grade BSI were included in the analysis. Overall splenectomy rates were 524 (17.5%), 448 (16.3%), and 32 (3.7%) in the ATC, MTC, and PTC groups, respectively. ATCs and MTCs had significantly higher splenectomy rates compared to PTCs (ATCs: OR = 5.72, 95%CI = 3.78-8.67, and p < 0.001 and MTCs: OR = 4.50, 95%CI = 2.97-6.81, and p < 0.001), while decreased trends in the splenectomy rates were observed in ATCs and MTCs (ATCs: OR = 0.92, 95%CI = 0.87-0.97, and p = 0.003 and MTCs: OR = 0.92, 95%CI = 0.87-0.98, and p = 0.013). CONCLUSIONS: This study suggested persistent disparities between different trauma center types in the management of children with high-grade BSI.

BACKGROUND: The aim of this systematic review was to assess the estimated incidence of pseudoaneurysm (PSA) with follow-up computed tomography (CT) for adult splenic injury with nonoperative management (NOM). METHODS: A systematic literature search was conducted in MEDLINE, Central, CINAHL, Clinical Trials, and ICTRP databases between January 1, 2010, and December 31, 2023. Quality assessment was performed using the Risk of Bias in Non-randomized Studies of Exposures (ROBINS-E) tool. Adult splenic injury patients who were initially managed with NOM and followed-up by protocolized CT were included. The primary outcome was the incidence of delayed PSA. Secondary outcome measures were delayed angiography and delayed splenectomy. Subgroup analyses were performed between NOM patients without initial splenic angioembolization (SAE) and NOM patients with initial SAE. RESULTS: Twelve studies were enrolled, including 11 retrospective studies and one prospective study, with 1746 patients in total. The follow-up CT rate in the included patients was 94.9%. The estimated incidence of PSA was 14% (95% confidence interval (CI), 8%-21%). The estimated delayed angiography and delayed splenectomy incidence rates were 7% (95% CI, 4%-12%) and 2% (95% CI, 1%-6%), respectively. Subgroup analyses showed that the estimated PSA incidence was 12% in NOM patients without initial SAE (95% CI, 7%-20%) and was also 12% in NOM patients with SAE (95% CI, 5%-24%). CONCLUSIONS: The estimated incidence of delayed PSA after follow-up CT for adult splenic injury with NOM was 14%. The estimated incidence of PSA in NOM with initial SAE was similar to that in NOM without initial SAE.

BACKGROUND: Multi-detector contrast-enhanced abdominal computed tomography (CT) allows for the accurate detection and classification of traumatic splenic injuries, leading to improved patient management. Their effective use requires rapid study interpretation, which can be a challenge on busy emergency radiology services. A machine learning system has the potential to automate the process, potentially leading to a faster clinical response. This study aimed to create such a system. METHOD: Using the American Association for the Surgery of Trauma (AAST), spleen injuries were classified into 3 classes: normal, low-grade (AAST grade I-III) injuries, and high-grade (AAST grade IV and V) injuries. Employing a 2-stage machine learning strategy, spleens were initially segmented from input CT images and subsequently underwent classification via a 3D dense convolutional neural network (DenseNet). RESULTS: This single-centre retrospective study involved trauma protocol CT scans performed between January 1, 2005, and July 31, 2021, totaling 608 scans with splenic injuries and 608 without. Five board-certified fellowship-trained abdominal radiologists utilizing the AAST injury scoring scale established ground truth labels. The model achieved AUC values of 0.84, 0.69, and 0.90 for normal, low-grade injuries, and high-grade splenic injuries, respectively. CONCLUSIONS: Our findings demonstrate the feasibility of automating spleen injury detection using our method with potential applications in improving patient care through radiologist worklist prioritization and injury stratification. Future endeavours should concentrate on further enhancing and optimizing our approach and testing its use in a real-world clinical environment.

BACKGROUND: The objective of this study was to identify factors associated with the use of spleen-conserving surgeries, as well as patient outcomes, on a national scale. METHODS: This retrospective cohort study (2010-2015) included patients (age≥16 years) with splenic injury in the National Trauma Data Bank. Patients who received a total splenectomy or a spleen-conserving surgery were compared for demographics and clinical outcomes. RESULTS: During the study period, 18,425 received a total splenectomy and 1,825 received a spleen-conserving surgery. Total splenectomy was more likely to be performed for patients with age>65 (odds ratio [OR]: 0.63, p â< â0.001), systolic blood pressure<90 (OR: 0.63, p â< â0.001), heart rate>120 (OR: 0.83, p â= â0.007), and high-grade injuries (OR: 0.18, p â< â0.001). Penetrating trauma patients were more likely to undergo a spleen-conserving surgery (OR: 3.31, p â< â0.001). The use of spleen-conserving surgery was associated with a lower risk of pneumonia (OR: 0.79, p â= â0.009) and venous thromboembolism (OR: 0.72, p â= â0.006). CONCLUSIONS: Spleen-conserving surgeries may be considered for patients with penetrating trauma, age<65, hemodynamic stability, and low-grade injuries. Spleen-conserving surgeries have decreased risk of pneumonia and venous thromboembolism.

BACKGROUND: Non-operative management of splenic injuries has significantly increased in the last decade with an increased emphasis on splenic preservation. This shift was assisted by increased availability of angioembolization, however, potential geographical variability in access exists in Aotearoa New Zealand (AoNZ). The aim of this study was to assess the management of splenic injury across AoNZ. METHOD: Five-year retrospective study of all patients admitted to AoNZ hospitals with blunt major trauma and a splenic injury. Patients were identified using the National Trauma Registry and cross-referenced with the National Minimum Data Set to determine their management. The primary outcome was the non-operative rate. RESULTS: Seven hundred seventy-three patients were included. Four hundred sixty-nine presented to a tertiary major trauma hospital and 304 to a secondary major trauma hospital. A difference was found in the rate of non-operative management between tertiary and secondary hospitals (P = 0.019). The rate of non-operative management was similar in mild (P = 0.814) and moderate (P = 0.825) injuries, however, significantly higher in severe injuries in tertiary hospitals (P = 0.009). No difference in mortality rate was found. CONCLUSION: This study found a difference in the management of splenic injuries between tertiary and secondary major trauma hospitals; predominantly due to a higher rate of operative management in patients with severe injuries at secondary hospitals. Despite this, no difference in mortality rate was found between tertiary and secondary hospitals.
RESUMO
Transcatheter arterial embolization (TAE) has increasingly replaced surgery for treating solid organ injuries, including the spleen, due to its minimally invasive approach. Studies show only a 3% splenectomy rate after TAE, despite a 10% incidence of missed vascular injuries in the American Association for the Surgery of Trauma (AAST) grade III splenic injuries on initial computed tomography (CT) scans. However, there's a lack of high-quality studies recommending specific CT follow-up intervals after non-operative management (NOM) of splenic injuries or guidelines for initiating treatment in cases of pseudoaneurysms or arteriovenous fistulas (AVFs). Here, we discuss the case of a 44-year-old man who presented with a splenic injury due to a motor vehicle accident. The splenic injury was AAST-spleen grade III, but because there was no evidence of extravascular leakage or AVF formation, NOM was selected. CT on the fifth day showed a pseudoaneurysm and an AVF, for which TAE was performed on the seventh day, preserving most of the parenchyma of the spleen with no complications. The indications for NOM as a treatment strategy for splenic injury are expanding, but since the 2018 revision of the AAST grading, the grade changes depending on the presence or absence of vascular injury, but in some cases, it is difficult to determine the presence or absence of active bleeding by CT findings. In fact, it has been reported that more than 25% of vascular lesions do not show up on CT, although CT has good sensitivity in detecting active bleeding, and the rate of NOM failure is higher in AAST grade III and above, so early angiography is likely to be useful. Splenic AVF may present with few symptoms in the early stages but may present with extrahepatic portal hypertension in the late stages, and patients may present to the hospital with symptoms such as abdominal pain and diarrhea. TAE is often the treatment of choice in traumatic cases, and the extent of embolization is important in the balance between preserving splenic function and completing treatment. The shift towards conservative management of splenic trauma may increase the occurrence of splenic AVFs. Transcatheter coil embolization of segmental branches has been effective in treating posttraumatic splenic AVFs, preserving splenic immune function and reducing risks linked to surgery and splenectomy.
RESUMO
Splenic rupture in haemodynamically unstable patients has traditionally been managed with splenectomy. This case report discusses the successful management of atraumatic splenic rupture, a rare but life-threatening complication of Epstein-Barr virus (EBV) infection, in a hemodynamically unstable patient. The patient, diagnosed with infectious mononucleosis (IM) secondary to EBV, presented with severe abdominal pain and a syncopal episode. Imaging revealed an American Association for the Surgery of Trauma (AAST) grade III splenic injury, which was subsequently upgraded to a grade IV injury on repeat imaging. The patient's condition deteriorated even with initial resuscitation, leading to splenic angioembolization. The procedure was successful and the patient was discharged after 5 days. This case highlights the efficacy of splenic artery embolization (SAE) in haemodynamically unstable patients with atraumatic splenic rupture, particularly in centers with interventional radiology resources, offering an alternative to splenectomy and its associated complications.
RESUMO
Background: Grade (III-V) blunt splenic injuries (BSI) in hemodynamically stable patients represent clinical challenges for successful non-operative management (NOM). In 2014, Our institution proposed a treatment protocol requiring splenic angiography and embolization for stable, intermediate, and high-grade BSI. It also included a follow-up CT scan for grade III BSI. We sought to assess the success rate of NOM in treating intermediate and high-grade BSI, following a standardized treatment protocol at a level 1 trauma center. Methods: An observational retrospective study was conducted. Data of patients with BSI from June 2011 to September 2019 were reviewed using the Qatar National Trauma Registry. Patients' demographics, CT scan and angiographic findings, grade of splenic injuries, and outcomes were analyzed. The pre- and post-implementation of treatment protocol periods were compared. Results: During the study period, a total of 552 hemodynamically stable patients with BSI were admitted, of which 240 had BSI with grade III to V. Eighty-one patients (33.8%) were admitted in the pre-protocol implementation period and 159 (66.2%) in the post-protocol implementation period. The NOM rate increased from 50.6% in the pre-protocol group to 65.6% in the post-protocol group (p = 0.02). In addition, failure of the conservative treatment did not significantly differ in the two periods, while the requirement for blood transfusion dropped from 64.2% to 45.9% (p = 0.007). The frequency of CT scan follow-up (55.3% vs. 16.3%, p = 0.001) and splenic arterial embolization (32.7% vs. 2.5%, p = 0.001) in NOM patients increased significantly in the post-protocol group compared to the pre-protocol group. Overall mortality was similar between the two periods. However, hospital and ICU length of stay and ventilatory days were higher in the post-protocol group. Conclusions: NOM is an effective and safe treatment option for grade III-V BSI patients. Using standardized treatment guidelines for intermediate-to high-grade splenic injuries could increase the success rate for NOM and limit unnecessary laparotomy. Moreover, angioembolization is a crucial adjunct to NOM that could improve the success rate.
RESUMO
Background: Iatrogenic splenic injury (ISI) is a recognized complication in radical gastrectomy that may result in incidental splenectomy (IS). However, the predictors of such events remain largely unknown. Methods: Medical records of the patients who underwent radical gastrectomy at our institution between January 2015 and December 2022 were retrospectively reviewed. Potential predictors of ISI and IS were collected and analyzed by multivariate logistic regression. Results were reported as an odds ratio (OR) with 95% confidence intervals (CI). Results: A total of 2916 patients were included, of whom 211 patients (7.2%) suffered from ISI and 75 patients (2.6%) underwent IS. Multivariate analysis demonstrated that BMI≥25 (OR: 3.198 (2.356-4.326), p<0.001), total gastrectomy (OR: 2.201 (1.601-3.025), p<0.001), and the existence of "criminal fold" (OR: 13.899 (2.824-251.597), p=0.011) were independent predictive risk factors for ISI; whereas laparoscopic surgical approach (OR: 0.048 (0.007-0.172), p<0.001) was a protective factor for ISI. Moreover, the existence of "criminal fold" (OR: 15.745 (3.106-288.470), p=0.008) and BMI≥25 (OR: 2.498 (1.002-6.046), p=0.044) were identified as independent risk factors of ISI under laparoscopic gastrectomy. There was no association between sex, age, previous abdominal surgery, neoadjuvant therapy, outlet obstruction, tumor stage, nodal stage, and total lymph node retrieved and ISI. Conclusions: BMI≥25 and total gastrectomy can predict high risk of ISI during radical gastrectomy. Laparoscopic surgery is superior to open gastrectomy in lowing the risk of ISI.
RESUMO
Background: Cardiopulmonary resuscitation is essential for cardiopulmonary arrest, but complications from chest compressions warrant monitoring. Although rib and sternal fractures are common, abdominal injuries are rare, and splenic injuries are much rarer. Case Presentation: A 74-year-old man was admitted to the emergency room with a hemorrhagic duodenal ulcer. During hospitalization, the patient went into cardiopulmonary arrest due to hemorrhagic shock. Spontaneous circulation returned after 7 min of cardiopulmonary resuscitation. He underwent transcatheter arterial embolization to stop the bleeding from the duodenal ulcer. The next day, a close examination of the patient's progressive anemia revealed splenic injury; transcatheter arterial embolization was performed to save his life. Conclusion: It is important to consider the complication of splenic injury in patients with cardiopulmonary arrest who have undergone appropriate cardiopulmonary resuscitation. A possible mechanism-especially in patients with a full stomach-is the squeezing of the spleen by the diaphragm, abdominal wall, and stomach.
RESUMO
BACKGROUND: The revised American Association for the Surgery of Trauma (AAST) organ injury scale (OIS) for splenic injury incorporates radiologic features but the implications of this are unknown. We hypothesized that the revised AAST-OIS would better predict outcomes. METHODS: Patients with a blunt splenic injury admitted to a Level I trauma center were reviewed from 2016 to 2021. Sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) for splenectomy were calculated for high-grade injuries (AAST-OIS grades IV-V) using both schemas. RESULTS: Of the 852 patients analyzed, 48.5% were observed, 24.6% were embolized, and the remaining underwent operative intervention. The median AAST-OIS increased from II to III (p â< â0.01). Sensitivity (38.0% vs. 73.7%) and NPV (80.9% vs. 88.2%) for splenectomy increased for high-grade injuries but specificity (93.5% vs 70.1%) and PPV (67.5% vs 46.7%) decreased. CONCLUSION: The revised AAST-OIS better predicted splenic salvage but is less accurate at predicting need for splenectomy.
RESUMO
Splenic injury is an extremely rare complication of endoscopic retrograde cholangiopancreatography (ERCP). There are only 34 cases reported in the literature up to now. Based on a case of a 72-year-old man, who after ERCP due to choledocholithiasis developed a large perisplenic and subcapsular hematoma, we carried out an extensive review of all cases of ERCP-induced splenic injury found in the literature. We searched PubMed/Medline and Google Scholar till 15 April 2023, for published case reports and series using the following terms: splenic injury after ERCP, ERCP-induced splenic injury, and post-ERCP splenic trauma. The case reports included were in English, Spanish, and German literature. We attempt to discuss the possible clinical image, the available diagnostic methods, the potential treatment alternatives, and predisposing factors related to this entity. Furthermore, a theory of a possible mechanism of this injury is discussed and supported schematically. The ERCP-induced splenic injury is rare and a high index of suspicion is needed for diagnosis. Therefore, we present two diagnostic algorithms, which according to our opinion may assist the evaluation of this complication and lead to early accurate diagnosis and appropriate management. Collectively, our findings support that although ERCP-induced splenic injury is an unexpected/unusual complication of ERCP, following the proper steps can be timely diagnosed and treated.
RESUMO
Correction of coagulation is a crucial aspect of trauma care. While there are reports highlighting the effectiveness of fibrinogen concentrate in severe trauma cases with coagulopathic complications, literature on its use in pediatric cases remains limited. This paper discusses the case of a 5-year-old male presenting with a splenic injury and associated coagulopathy. We administered fibrinogen concentrate to enhance his coagulability prior to performing transcatheter arterial embolization utilizing gelatin sponges, aiming for optimal hemostasis. Post-administration, the patient's fibrinogen levels improved significantly, leading to successful hemostasis and a positive clinical outcome.
RESUMO
PURPOSE: This study aimed to elucidate the treatment approach for blunt splenic injuries concurrently involving the aorta. We hypothesized that non-operative management failure rates would be higher in such cases, necessitating increased hemorrhage control surgeries. METHODS: Data from the Trauma Quality Improvement Program spanning 2017 to 2019 were utilized. All patients with blunt splenic trauma were considered for inclusion. We conducted comparisons between blunt splenic trauma patients with and without thoracic or abdominal aortic injuries to identify any potential disparities in treatment. RESULTS: Among the 32,051 patients with blunt splenic injuries during the study period, 752 (2.3%) sustained concurrent aortic injuries. Following 2:1 propensity score matching, it was determined that the presence of aortic injuries did not significantly affect the utilization of splenic transarterial angioembolization (TAE) (7.2% vs. 8.7%, p = 0.243) or the necessity for splenectomy or splenorrhaphy (15.3% vs. 15.7%, p = 0.853). Moreover, aortic injuries were not a significant factor contributing to TAE failure, regardless of the location or severity of the injury. Patients with simultaneous splenic and aortic injuries required more red blood cell transfusion within first 4 hours (0 ml [0, 900] vs. 0 ml [0, 650], p = 0.001) and exhibited a higher mortality rate (10.6% vs. 7.9%, p = 0.038). CONCLUSION: This study demonstrated that patients with concurrent aortic and splenic injuries presented with more severe conditions, higher mortality rates, and extended hospital stays. The presence of aortic injuries did not substantially influence the utilization of TAE or the necessity for splenectomy or splenorrhaphy. Patients of this type can be managed in accordance with current treatment guidelines. Nonetheless, given their less favorable prognosis, they necessitate prompt and proactive intervention.

BACKGROUND: Over recent decades, splenic angioembolization (SAE) as an adjunct to non-operative management (NOM) has emerged as a prominent intervention for patients with blunt splenic injuries (BSI). SAE improves patient outcomes, salvages the spleen, and averts complications associated with splenectomy. This systematic review aimed to evaluate the failure rate and complications related to SAE in patients with BSI. METHODS: A systematic literature search (PubMed, SCOPUS, and Cochrane Library) focused on studies detailing splenic angioembolization in blunt trauma cases. Articles that fulfilled the predetermined inclusion criteria were included. This review examined the indications, outcomes, failure rate, and complications of SAE. RESULTS: Among 599 identified articles, 33 met the inclusion criteria. These comprised 29 retrospective studies, three prospective studies, and one randomized control trial. The analysis encompassed 25,521 patients admitted with BSI and 3,835 patients who underwent SAE. The overall failure rate of SAE was 5.3 %. Major complications predominantly were rebleeding (4.8 %), infarction (4.6 %), and abscess formation (4 %). Minor complications were fever (18.4 %), pleural effusion (13.1 %), and coil migration (3.9 %). Other complications included splenic atrophy, splenic cyst, hematoma, and access site complications such as splenic/femoral dissection. Overall, post embolization mortality was 0.08 %. CONCLUSION: SAE is a valuable adjunct in managing BSI, with a low failure rate. However, this treatment modality is not without the risk of potentially serious complications.
RESUMO
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.
RESUMO
BACKGROUND: The prone lateral approach to lumbar spine surgery is known to have a multitude of potential complications, including damage to neurovascular structures, surrounding viscera, and intra-abdominal structures near the surgical site. However, iatrogenic injury to the spleen following prone lateral lumbar discectomy and arthrodesis as a potential complication has not yet been described in the literature. OBSERVATIONS: The authors present the case of a 71-year-old female with a history of L3-S1 laminectomy and L3-5 arthrodesis who underwent a prone lateral discectomy of L2-3 with arthrodesis of the endplates for chronic lower-back pain. On postoperative day 1, the patient developed hypotension unresponsive to pressor medications, significant abdominal pain, and anemia requiring 2 transfusions. Bedside ultrasound revealed free fluid in the abdomen. She then underwent an exploratory laparotomy for splenic injury. LESSONS: Although rare, splenic rupture should be considered as part of the differential diagnosis for patients with hemodynamic instability after lateral surgical approaches to the lumbar spine. Any patient with evidence of hypotension, anemia, and/or abdominal pain following lumbar surgery should be evaluated for splenic injury with an abdominal computed tomography scan and considered for surgical intervention. https://thejns.org/doi/10.3171/CASE23639.
