RESUMO

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.

RESUMO

BACKGROUND: Sinistral, or left-sided, portal hypertension (SPH) is a rare cause of upper gastrointestinal (GI) hemorrhage resulting from obstruction of the splenic vein. Venous drainage from the spleen via collaterals can result in venous hemorrhage into both the retroperitoneal and intra-abdominal spaces due to increased venous blood pressure in peripancreatic and gastroduodenal vasculature. SPH can occur secondary to pancreatitis with thrombosis of the splenic vein. Another possible cause is the surgical ligation of the splenic vein as part of pancreaticoduodenectomy (PD). Although splenectomy has been traditionally considered as the treatment of choice to relieve venous hypertension, individual concepts for each patient have to be developed. Considering the venous collateral drainage pathways, a comprehensive approach involving surgical, endoscopic, and interventional radiology interventions may be necessary to address the underlying cause of variceal bleeding. Among these approaches, splenic artery embolization (SAE) has demonstrated efficacy in mitigating the adverse effects associated with elevated venous outflow pressure. SUMMARY: This review summarizes key imaging findings in SPH patients after PD and highlights the potential of minimally invasive embolization for curative treatment of variceal hemorrhage. KEY MESSAGES: (i) SPH is a potential consequence after major pancreas surgery. (ii) Collateral flow can lead to life-threatening abdominal bleeding. (iii) Depending on the origin and localization of the bleeding, a dedicated management is required, frequently involving interventional radiology techniques.

RESUMO

BACKGROUND: Splenic sequestration crisis is a potentially fatal complication of sickle cell disease, mainly seen in young children. Only a few case series describe the acute splenic sequestration crisis in adults and its management, which primarily consists of supportive care and, in some cases, splenectomy. Splenic artery embolization has seldom been described in sickle cell disease. This is probably the first case in which an adult with sickle cell disease presented with an acute splenic sequestration crisis was managed successfully through splenic artery embolization. RESULTS: This 22-year-old female, a known case of sickle cell disease, presented with severe pain in the abdomen and low-grade intermittent fever for two days, secondary to an acute splenic sequestration crisis. The diagnosis of acute splenic sequestration was made based on clinical and blood parameters, ultrasonography, and computed tomography. Even with adequate supportive care and blood transfusions, the patient's condition worsened with a rapid fall in the hemoglobin and total platelet count. Considering splenectomy to be a high-risk procedure for this patient, a decision of rescue splenic artery embolization was taken, which was successful. CONCLUSION: Splenic artery embolization may be considered a lifesaving procedure in patients with acute splenic sequestration, where the risk of splenectomy can be high. Adequate post-procedure supportive care is vital for preventing complications.

RESUMO

OBJECTIVE: Aim: To evaluate the effectiveness of PSAE for secondary prevention of VB episodes in patients with chronic liver disease (CLD) and CSPH. PATIENTS AND METHODS: Materials and Methods: One hundred twenty patients (from 2008 to 2020) were submitted of PSAE as secondary prevention treatment. The results of the treatment of 27 patients between 2008 and 2012 (first period) were compared with those of 93 patients treated with PSAE since 2013 (second period), as procedure and management protocol were modificated. VB recurrence rate and mortality (related and non-related to bleeding episodes) were defined as study end-points in both groups at 12-months follow-up. RESULTS: Results: At 12-months follow-up, 11 (40,7 %) and 54 (58,1 %) patients in groups 1 and 2, respectively, were free from VBs (p=0,129). Overall mortality rate was significantly higher in group 1, as compared to group 2: 10 (37,0 %) versus 6 (6,4 %) patients, respectively (p<0,001), - due to higher frequency of fatal VB events (7 (26,0 %) vs. 3 (3,2 %) patients, respectively; p=0,001). CONCLUSION: Conclusions: PSAE is an effective treatment for secondary prevention of VB in patients with CLD and CSPS. The management protocol modification resulted in the decrease in overall mortality rate and mortality related to recurrent VB episodes.

RESUMO

BACKGROUND: This study aimed to evaluate the management of blunt splenic injury (BSI) and highlight the role of splenic artery embolization (SAE). METHODS: We conducted a retrospective review of all patients with BSI over 15 years. Splenic injuries were graded by the 2018 revision of the American Association for the Surgery of Trauma-Organ Injury Scale (AAST-OIS). Our hospital provide 24/7 in-house surgeries and 24/7 in-house interventional radiology facility. Patients with BSI who arrived hypotensive and were refractory to resuscitation required surgery and patients with vascular injury on abdominal computed tomography were considered for SAE. RESULTS: In total, 680 patients with BSI, the number of patients who underwent nonoperative management with observation (NOM-obs), SAE, and surgery was 294, 234, and 152, respectively. The number of SAEs increased from 4 (8.3%) in 2001 to 23 (60.5%) in 2015 (p < 0.0001); conversely, the number of surgeries decreased from 21 (43.8%) in 2001 to 4 (10.5%) in 2015 (p = 0.001). The spleen-related mortality rate of NOM-obs, SAEs, and surgery was 0%, 0.4%, and 7.2%, respectively. In the SAE subgroup, according to the 2018 AAST-OIS, 234 patients were classified as grade II, n = 3; III, n = 21; IV, n = 111; and V, n = 99, respectively.; and compared with 1994 AST-OIS, 150 patients received a higher grade and the total number of grade IV and V injuries ranged from 96 (41.0%) to 210 (89.7%) (p < 0.0001). On angiography, 202 patients who demonstrated vascular injury and 187 achieved hemostasis after SAE with a 92.6% success rate. Six of the 15 patients failed to SAE preserved the spleen after second embolization with a 95.5% salvage rate. CONCLUSIONS: Our data confirm the superiority of the 2018 AAST-OIS and support the role of SAE in changing the trend of management of BSI.

RESUMO

BACKGROUND: To compare the outcomes of blunt splenic injuries (BSI) managed with proximal (P) versus distal (D) versus combined (C) splenic artery embolization (SAE). METHODS: This retrospective study included patients with BSI who demonstrated vascular injuries on angiograms and were managed with SAE between 2001 and 2015. The success rate and major complications (Clavien-Dindo classification ≥ III) were compared between the P, D, and C embolizations. RESULTS: In total, 202 patients were enrolled (P, n = 64, 31.7%; D, n = 84, 41.6%; C, n = 54, 26.7%). The median injury severity score was 25. The median times from injury to SAE were 8.3, 7.0, and 6.6 h for the P, D, and C embolization, respectively. The overall haemostasis success rates were 92.6%, 93.8%, 88.1%, and 98.1% in the P, D, and C embolizations, respectively, with no significant difference (p = 0.079). Additionally, the outcomes were not significantly different between the different types of vascular injuries on angiograms or the materials used in the location of embolization. Splenic abscess occurred in six patients (P, n = 0; D, n = 5; C, n = 1), although it occurred more commonly in those who underwent D embolization with no significant difference (p = 0.092). CONCLUSIONS: The success rate and major complications of SAE were not significantly different regardless of the location of embolization. The different types of vascular injuries on angiograms and agents used in different embolization locations also did not affect the outcomes.

RESUMO

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.

RESUMO

BACKGROUND: Sinistral portal hypertension (SPH) is a rare clinical syndrome. The purpose of this study was to assess the clinical outcomes and safety of splenic artery embolization (SAE) in the treatment of SPH. METHODS: This retrospective study included 39 SPH patients who underwent SAE treatment between August 2009 and May 2021. The cases had esophageal, gastric, or ectopic varices detected by endoscopy or enhanced CT, with symptoms or signs of upper gastrointestinal (GI) bleeding and/or postprandial fullness. Clinical symptom improvement rate, complications, and symptomatic recurrence rate were observed and analyzed after treatment. RESULTS: All the procedures were performed successfully. Of all patients, 17 received the 2-step complete SAE procedure, 19 received only the first step of the 2-step protocol (i.e., partial splenic embolization [PSE] procedure), and the remaining three received the 1-step complete SAE procedure. After the procedures, the symptoms completely disappeared in all patients, and the main complications were post-embolization syndromes, with 27 patients (69.2%) developing a low-grade fever, 24 (61.5%) developing abdominal pain and 4 (10.3%) developing nausea or mild vomiting. During the prolonged follow-up, varicose veins were gradually reduced as detected by enhanced CT; liver function parameters and platelet count remained in the normal range. Only one patient who underwent PSE treatment developed upper GI rebleeding 7 months after the procedure. CONCLUSION: Two-step complete SAE is a safe and feasible procedure for the treatment of symptomatic SPH.

RESUMO

Long-term complications after the Fontan procedure are important concerns for patients with pediatric and adult congenital heart disease. Although thrombocytopenia due to portal hypertension and hypersplenism is a well-known complication of the Fontan circulation, few studies have reported on its management. Herein we describe a young adult Fontan patient with thrombocytopenia and a splenic artery aneurysm caused by conduit stenosis. The patient required conduit replacement due to high venous pressure. We performed partial splenic artery embolization (PSE) and embolization of the aneurysm preoperatively to reduce the risk of bleeding, resulting in successful subsequent cardiac surgery. Preoperative evaluation of the splenic artery aneurysm was informative, and PSE was a safe and effective treatment option for thrombocytopenia to avoid bleeding during open-heart surgery in this patient.

RESUMO

OBJECTIVE: To analyze the results of diagnosis and treatment of true splenic artery aneurysms. MATERIAL AND METHODS: We analyzed the results of diagnosis and treatment of 27 patients with true splenic artery aneurysm. All ones underwent surgical treatment at the Botkin Municipal Clinical Hospital between 2017 and 2021. Splenic artery aneurysm >1 cm was an indication for surgical treatment. Surgical option depended on aneurysm location. Laparoscopic splenectomy and aneurysmectomy were performed in 4 cases (14.8%), 5 (18.5%) patients underwent endovascular intervention, laparoscopic clipping was performed in 18 (66.7%) cases. Methods of surgical treatment, general and specific postoperative complications according to the Clavien-Dindo and ISGPS classifications were analyzed. RESULTS: Laparoscopic clipping was accompanied by fewer general and specific postoperative complications. Specific complications after laparoscopic splenectomy occurred in 2 patients (BL according to the ISGPS 2016 classification). There was one case of acute pancreatitis after endovascular interventions. In long-term postoperative period, aneurysm recanalization after endovascular intervention was observed in 1 case. CONCLUSION: Surgical treatment of splenic artery aneurysms requires a differentiated approach based on topographic and anatomical assessment of aneurysm relative to the arterial vessel.

RESUMO

BACKGROUND: Minimally invasive splenectomy (MIS) is increasingly favored for the treatment of benign and malignant diseases of the spleen over open access approaches. While many studies cite the superiority of MIS in terms of decreased morbidity and length of stay over a traditional open approach, the comparative effectiveness of specific technical and peri-operative approaches to MIS is unclear. OBJECTIVE: To develop evidence-based guidelines that support clinicians, patients, and others in decisions on the peri-operative performance of MIS. METHODS: A guidelines committee panel of the Society of American Gastrointestinal and Endoscopic Surgeons (SAGES) including methodologists used the Grading of Recommendations Assessment, Development and Evaluation approach to grade the certainty of evidence and formulate recommendations. RESULTS: Informed by a systematic review of the evidence, the panel agreed on eight recommendations for the peri-operative performance of MIS for adults and children in elective situations addressing six key questions. CONCLUSIONS: Conditional recommendations were made in favor of lateral positioning for non-hematologic disease, intra-operative platelet administration for patients with idiopathic thrombocytopenic purpura instead of preoperative administration, and the use of mechanical devices to control the splenic hilum. Further, a conditional recommendation was made against routine intra-operative drain placement.

RESUMO

BACKGROUND: Thrombotic complications following splenectomy have been documented. However, there has been sparse literature regarding thrombotic complications following splenic artery embolization (SAE).The objective of this study was to determine changes in coagulation and fibrinolysis and assess the thrombotic risk after SAE in patients with blunt splenic injury (BSI). METHODS: This study included 38 BSI patients who were hemodynamically stable on admission. SAE was performed if the splenic injury was classed as grade III or greater and had no requirement of immediate surgery. Platelet (PLT), fibrinogen (FIB), D-dimers (D-D), fibrinogen/fibrin degradation products (FDP), antithrombin III (AT III), prothrombin time (PT), activated partial thromboplastin time (APTT), thrombin time (TT), hemoglobin (Hb), and hematocrit (Hct) were measured before SAE procedures and then 1d, 3d, and 7d after SAE. RESULTS: The technical success rate of SAE and the splenic salvage rate were 100%. There was no mortality. Compared with pre-SAE values, the levels of PLT, FIB, D-D, and FDP increased significantly at 3 days and 7 days after SAE (p < 0.05). However, AT III, PT, APTT, TT, Hb, and Hct showed no statistically significant difference at 1d, 3d, and 7d after SAE (p > 0.05). CONCLUSION: Alterations in PLT and hemostatic parameters might contribute to the increased risk of thrombotic complications in BSI patients undergoing SAE. Thromboembolism following SAE should be considered and thrombotic prophylaxis should be recommended.

RESUMO

Myelofibrosis (MF) is a chronic myeloproliferative neoplasm which can lead to massive splenomegaly secondary to extramedullary hematopoiesis. Patients frequently exhibit debilitating symptoms including pain and early satiety, in addition to cellular sequestration causing severe cytopenias. JAK 1/2 inhibitors, such as ruxolitinib and fedratinib, are the mainstay of therapy and produce significant and durable reductions in spleen volume. However, many patients are not eligible for JAK 2 inhibitor therapy or become refractory to treatment over time. Novel therapies are in development that can reduce the degree of splenomegaly for some of these patients. However, splenectomy, splenic irradiation, and partial splenic artery embolization remain valuable therapeutic options in select patients. In this review, we will discuss currently available pharmacologic therapies and describe promising drugs currently in development. We will also delve into the efficacy and safety concerns of splenectomy, splenic irradiation, and partial splenic artery embolization. Finally, we will propose a treatment algorithm to help guide clinicians in the management of symptomatic splenomegaly in patients with MF.

RESUMO

OBJECTIVE: The purpose of this prospective study is to evaluate the efficiency of perioperative spleen embolization prior to laparoscopic splenectomy indicated for hypersplenism. METHODS: We conducted a prospective study exploring a technique combining ultra-selective perioperative embolization and splenectomy. Between January 2008 and March 2013, 16 splenectomies were performed in children suffering from hypersplenism due to varying hematologic diseases. Spleen embolization was performed by an interventional radiologist in the operating room (OR) just before splenectomy and during the same general anesthesia. Ages varied from 3 to 17 years. Spleen volume was measured by preoperative ultrasound. One patient underwent a laparotomy because of suspected adhesions due to previous surgery. All other operations were performed laparoscopically. RESULTS: One complication arose from embolization: a perforation of the splenic artery. After immediately placing a platinum coil proximal to the perforation, the splenectomy was carried out as usual. Fourteen children (87.5 %) had splenomegaly, of which eight (50 %) had massive splenomegaly. There were no deaths, no conversions to laparotomy, no reoperations and none of these patients had to be transfused. CONCLUSIONS: Perioperative spleen embolization performed in the OR by an interventional radiologist makes laparoscopic splenectomy a safer procedure. We propose a preoperative method for spleen measurement that is adapted to children: simple and massive splenomegaly is defined through patient body weight and a preoperative ultrasound. We conclude that spleen size is no more a limiting factor for laparoscopic splenectomy in children.

RESUMO

Background and aims: Partial splenic artery embolization (PSAE) is an alternative treatment modality for managing hypersplenism secondary to portal hypertension. We are presenting a case series of patients with portal hypertension who underwent PSAE for symptomatic hypersplenism. Methods: We included patients with portal hypertension who underwent PSAE from January 2022 to December 2022. Patients' characteristics and procedure related complications were noted. Data were analyzed for improvement in the hematological parameters. Results: A total of 11 (7 women, median age 34 [18-56] years) patients were included. Three patients were cirrhotic (hepatitis B-2, metabolic dysfunction-associated steatotic liver disease -1) and 8 were non-cirrhotic (extra-hepatic portal vein obstruction-5, Non cirrhotic portal fibrosis-3). Splenic artery aneurysm was concomitantly present in 5 cases. Technical success was achieved in all cases. Post embolization, hemoglobin, white blood cells and platelet counts improved at 4 weeks, 12 weeks and 24 weeks along with symptomatic improvement. All patients had post-embolization syndrome. One patient developed transient ascites and secondary bacterial peritonitis which was managed conservatively. One patient died due to splenic abscess and septicemia. Conclusion: Although, hematological parameters and symptoms improve post procedure, PSAE is associated with major complications and should be performed judiciously in selected cases only.

RESUMO

Venous stasis ulcers are nonhealing lesions due to venous hypertension secondary to valvular dysfunction or deep venous outflow obstruction. We describe a case of a 71-year-old male with a history of polycythemia vera, secondary myelofibrosis, and massive splenomegaly up to 38 cm who presented with chronic, perimalleolar venous stasis ulcers and pain on the left lower extremity. CT showed significant compression of the left common iliac vein due to mass effect from the spleen. He was managed medically while being evaluated for partial splenic artery embolization but expired due to other chronic conditions before any intervention could be performed. Partial splenic artery embolization may be considered as a treatment option for patients with symptomatic iliac vein compression due to massive splenomegaly secondary to myelofibrosis, as long as extramedullary hematopoiesis is not compromised.

RESUMO

OBJECTIVE: This systematic review aims to elucidate the diagnostic capabilities of imaging techniques in identifying Non-Occlusive Hepatic Artery Hypoperfusion Syndrome (NOHAH) and to evaluate the efficacy and outcomes of splenic artery embolization (SAE), including the choice and placement of embolic agents. MATERIALS AND METHODS: A comprehensive literature search was conducted using PubMed, CINAHL, and Scopus databases, adhering to PRISMA guidelines. Fifteen studies encompassing 240 patients treated with embolization (using coils or Amplatzer Vascular Plugs (AVP)) were analyzed. Key metrics assessed included patient demographics, embolization techniques, embolic agents, technical success, radiologic findings pre- and post-embolization, and complication rates. RESULTS: Among the 240 patients studied, 177 (73.8%) were reported by gender, with a majority being male (127/177, 71.7%). Doppler ultrasonography (DUS) emerged as the primary initial screening tool in 80% of studies. The hepatic arterial resistive index (RI) was a critical parameter, with mean values significantly decreasing from 0.84 pre-embolization to 0.70 post-embolization (p < 0.001). All cases confirmed technical success via digital subtraction angiography, revealing delayed hepatic arterial filling without stenosis or thrombosis. Coils were the predominant embolic agent, used in 80.8% of patients, followed by AVP in 16.3%. The overall mortality rate was 4.58%, with 29 major and 3 minor complications noted. Notably, proximal placement of coils in the splenic artery was associated with lower mortality rates compared to distal placement and showed comparable complication rates to AVPs. CONCLUSION: DUS is a reliable screening modality for NOHAH, with post-SAE assessments showing significant improvements. The choice and location of embolization significantly impact patient outcomes, with proximal placement of coils emerging as a preferable strategy due to lower mortality rates and comparable complication profiles to alternative methods.

RESUMO

BACKGROUND: Splenic rupture associated with Behçet's syndrome (BS) is extremely rare, and there is no consensus on its management. In this case report, a patient with BS-associated splenic rupture was successfully treated with splenic artery embolization (SAE) and had a good prognosis after the intervention. CASE SUMMARY: The patient was admitted for pain in the left upper abdominal quadrant. He was diagnosed with splenic rupture. Multiple oral and genital aphthous ulcers were observed, and acne scars were found on his back. He had a 2-year history of BS diagnosis, with symptoms of oral and genital ulcers. At that time, he was treated with oral corticosteroids for 1 month, but the symptoms did not alleviate. He underwent SAE to treat the rupture. On the first day after SAE, the patient reported a complete resolution of abdominal pain and was discharged 5 d later. Three months after the intervention, a computed tomography examination showed that the splenic hematoma had formed a stable cystic effusion, suggesting a good prognosis. CONCLUSION: SAE might be a good choice for BS-associated splenic rupture based on good surgical practice and material selection.
