2011;11 (3): 276-81. The Splenic laceration grading calculator provides the injury grade which is then used alongside with the severity of other injuries in planning the intraoperative management and whether there is need for a transfusion protocol to be put in place as well. The spleen is an extremely vascular organ and consequently splenic rupture can lead to large intraperitoneal haemorrhage, rapidly leading to fatal haemorrhagic shock.. Whilst protected by the ribcage (Fig. Adult trauma surgeons have learned from their pediatric counterparts that non- operative management is possible even with higher grade injuries; interventional radiology has increased successes with non-operative approaches. Congenital cleft spleen with CT scan appearance of high-grade splenic laceration after blunt abdominal trauma The Journal of Emergency Medicine, Vol. 8. The most commonly used injury classification is the American Association for the Surgery of Trauma (AAST) grading scale, which demarcates 5 grades of splenic injury (grades I-V) with a higher number indicating worse severity. Though there is little evidence yet in the literature to substantiate many of the recommendations in institutional protocols, success with NOM requires firm clinical guidelines. The most accepted grading scale for splenic injury was established by the American Association for the Surgery of Trauma in 1987 and revised in 1997 (FIGURE 1). In the unstable patient, the sonographic exam (FAST) has proven an excellent tool to evaluate the presence or absence of intra-abdominal fluid and has largely replaced diagnostic peritoneal aspiration (DPA). d) How long should anticoagulation be interrupted? It is our institutional practice to admit all injuries grade III or above to the intensive care unit. At present, they are classified according to the anatomy of the injury. Patients who sustain an The period of observation is debatable and the clinical condition and progress of the patient should play a role in deciding duration. The optimal treatment strategy, however, should keep into consideration the hemodynamic status, the anatomic derangement, and the associated injuries. AAST Grade 5 Splenic Injury: 1. 2012;18 (1): 60-7.

If the vessel injury is within 2 cm of the organ parenchyma, refer to specific organ injury scale. This case-based approach to emergency medicine is a unique and underutilized teaching strategy, written for emergency room residents and nurses. Grade 3 to 4 in this case). Thus, the management of splenic trauma should be ultimately multidisciplinary and based on the physiology of the patient, the anatomy of the injury, and the associated lesions. In the adult population, the numbers are substantially lower, with 60% of all splenic injuries managed non-operatively, with a failure rate of about 10%. Finally, children are simply injured in a different fashion than are adults. Found insideThis text unifies this body of knowledge into an educational resource capturing the core competencies required of an emergency radiologist. According to Marmery, the splenic lesion is classified from Grade 1 to Grade 3, and the grade increases according to the depth of the laceration [14, 27]. We certainly recognize the importance of the spleen in the pediatric population where NOM has been a longtime norm and overwhelming post-splenectomy sepsis (OPSI) is more problematic. Peitzman AB, Heil B, Rivera L, et al. Injury is an increasingly significant health problem throughout the world, accounting for 16 per cent of the global burden of disease. 7. Note: Advance one grade for multiple splenic injuries up to grade 3. Increase one grade for multiple grade III or IV injuries involving > 50% vessel circumference. J Chir (Paris) 2008; 145:561-7.

Case 11: grade III with day 5 delayed traumatic pseudoaneurysm, Case 13: grade IV with delayed pseudoaneurysms, inhomogeneous splenic enhancement (zebra or psychedelic spleen), sclerosing angiomatoid nodular transformation (SANT), extramedullary hematopoiesis in the spleen, inflammatory myofibroblastic tumor of the spleen, fresh blood is usually characterized as echoes free, absence of free fluid does not rule out splenic injury, disruption to the splenic echotexture indicating laceration or hypoechoic regions representing hematoma may be present, lacerations appear as linear or branching hypodensities (geographic pattern), subcapsular hematomas can be seen as low-density fluid adjacent to the spleen that distorts the splenic architecture, active hemorrhage appears as a high-density (80-95 HU) material due to the extravasation of contrast media that increases in size on delayed imaging, splenic clefts may be mistaken for a laceration, these are due to persistent lobulation of the spleen after development, in contrast to a laceration, a cleft is usually smooth with a rounded edge and are not associated with an adjacent subcapsular hematoma or perisplenic fluid. Splenic hilum is preserved. Found insideEmergency Cross-sectional Radiology is a practical aide-memoire for emergency medicine physicians, surgeons, acute care physicians and radiologists in everyday reporting or emergency on-call environments. Much consideration is needed in cases of trauma in elderly patients as they may initially present with few findings due to altered physiology as a result of medications such as beta blockers. Splenic injury is classified based on CT findings according to the American Association for the Surgery of Trauma (AAST) Organ Injury Scale. Case 10: grade III with day 5 delayed traumatic pseudoaneurysm, sclerosing angiomatoid nodular transformation (SANT), extramedullary hematopoiesis in the spleen, inflammatory myofibroblastic tumor of the spleen, ruptured subcapsular or intraparenchymal hematoma ≥5 cm, any injury in the presence of a splenic vascular injury* or active bleeding confined within splenic capsule, parenchymal laceration involving segmental or hilar vessels producing >25% devascularisation, any injury in the presence of splenic vascular injury* with active bleeding extending beyond the spleen into the peritoneum, advance one grade for multiple injuries, each up to grade III, "vascular injury" (i.e. This resulted in a 97% splenic salvage rate in 341 patients over a 2 year study period. later) phase.

Chief of the Department of Trauma, Critical Care, and Acute Care Surgery, Penn State Milton S. Hershey Medical Center, The amount of hemoperitoneum (HP) can also be useful to determine the approach to the patient with an injured spleen. CONCLUSION: The best individual predictor of successful observation in patients with blunt splenic injury was the CT-based grading system. In the unstable patient, the algorithm utilizes Focused Assessment with Sonography for Trauma (FAST) and Diagnostic Peritoneal Aspiration (DPA) to determine the presence of intra-abdominal blood and, ultimately, the need for operative intervention. We also have a greater understand of transfusion,the adverse consequences of transfusion, and the morbidity associated with stored blood products. If the spleen has sustained only minimal damage there are several options for splenic salvage. Published in association with the American Society of Emergency Radiology, the medical reference book is designed to help experienced radiologists, residents, or emergency medicine practitioners accurately address problematic conditions and ...

Radiographics. 1), the majority of cases of splenic injury are secondary to abdominal trauma - particularly blunt trauma. On the contrary, the Memphis group in their study of 558 patients with blunt splenic injury demonstrated that HP alone was not independently predictive of the need for operative intervention and should not be a contraindication for NOM.4. The question of where to admit should be based on injury grade. We also describe the technique of splenectomy and its complications. This book offers a comprehensive review on the last development in the management and the treatment of acute and life-threatening conditions. 4. It is particularly vulnerable to trauma of the left lower thorax. Siriratsivawong and colleagues concluded that mortality was high regardless of failure of NOM, but significant increases in hospital stay and ICU LOS were found in those patients over 55 years of age.

What explains the divergent experience of NOM in pediatric and adult populations? If severely damaged, it is removed after securing its blood supply with careful attention to avoiding injury to the tail of the pancreas. In this study, most of the clinical parameters that were used as variables for treatment decision making typically were available when patients with blunt splenic injury were admitted, and the CT grading scale score was significantly (P < .0001) better than all clinical parameters except the abdominal abbreviated injury scale score to help determine the most effective treatment. These include partial splenectomy or a mesh wrapped repair. Shankar S, Rowe S.

Splenic salvage is once again considered appropriate, reinforced by the pediatric experience with successful non-operative management (NOM), an understanding of the intact spleen’s vital role in healthy immune function, and the use of more detailed diagnostic modalities to further delineate the extent of injury. To evaluate the efficacy of this procedure, we graded splenic injury based upon the extent of splenic repair in 77 patients with blunt abdominal trauma. In addition, we have learned much concerning the inflammatory cascade, which - if unchecked - can cause undue morbidity and mortality. .

Special consideration is in order for injured pregnant women with viable preterm fetuses who would not tolerate the stress of NOM failure. b) How long should the observation period last? The other complications of splenectomy include bleeding, infection, pancreatic fistula, thrombosis, thrombocytosis, and death. 4. Consider for Grade IV or V injury in children or adults if no significant hemoperitoneum is present. Rapid resuscitation techniques are applied to the unstable patient while simultaneously attempting to rapidly identify the source of hemorrhage. 1—36-year-old man with active splenic bleeding who was admitted after motor vehicle collision. J Trauma 1998; 45:692-7; discussion 697-9. The right lobe is injured slightly more frequently than the left. In the past, 40-50% of injured spleens required operative intervention, most likely due to confusion regarding splenic function, as well as about diagnosis in the pre-CT era. Pancreatic fistula (PF) can be an early or late complication of splenectomy and lead to local infection, pseudocyst formation, and sepsis. In the abdomen, an injured spleen is the most frequent cause of major bleeding. 25, No. There is one nuance that people frequently don't appreciate: multiple injuries can increase the grade. 1. 3. Twelve of the 68 patients with a grade III injury (18%), four of the 25 with a grade IV injury (16%), and two of the three with a grade V injury had contained vascular injuries . A diagnostic peritoneal lavage, while not ideal, may be used to evaluate the presence of internal bleeding a person who is hemodynamically unstable. The spleen is the most commonly injured organ in blunt abdominal trauma. Protocols should address several key questions: Where should the patient be admitted (based on grade level). colonoscopy). 6.

There are five grades of splenic injury (Fig. There are probably insufficient data about the success of this strategy for Grade V injuries. Each year in the United States approximately 1.5 million adults suffer blunt injury with almost 40 000 suffering a splenic injury.1 Based on recent studies, as well as data from the American College of Surgeons National Trauma Data Bank, 10% to 15% of patients admitted with blunt splenic injury will undergo an urgent splenectomy within six hours of admission, primarily due to . Splenectomy is historically the treatment of choice. 2004;59 (4): 342-8. Certain grade I injuries may not require admission and observation, but always while taking into account that CT is notorious for underestimating injury.

NOM was ultimately successful for 80.1% of patients with a small amount of blood versus only 27.4% with a large HP.3 Gonzales and associates reported the failure of NOM based on the quantity of HP to be 10%, 22%, and 48% for small, moderate, and large amounts of fluid, respectively.7 Similar conclusions were drawn by Sharma and colleagues in their patient populations with large HP. iatrogenic). The most accepted grading scale for splenic injury was established by the American Association for the Surgery of Trauma in 1987 and revised in 1997 (FIGURE 1). 3. Active contrast extravasation should prompt either coil embolization by interventional radiology, or operative intervention, depending on institutional resources and continued patient stability. Hassan R, Abd Aziz A, Md Ralib AR et-al. Non-operative management of blunt splenic injury is appropriate in hemodynamically stable patients without evidence of peritonitis. The use of follow-up imaging is controversial, and there is no general consensus on the utility of repeat CT scans.
