  3. Radiation to left Shoulder (Kehr Sign) or right Shoulder
  4. Nausea
  5. Vomiting
  • Signs

  2. Left upper quadrant tenderness
  3. Abdominal guarding and Rebound Tenderness
  4. Hemoperitoneum findings (delayed presentation)
    1. Periumbilical Ecchymosis (Cullen Sign)
    2. Flank Eccymosis (Turner Sign)
  • Imaging
  1. Fast Scan
  2. CT Abdomen and Pelvis with IV Contrast
  • Precautions
  1. Splenic capsule may contain intial Hemorrhage
    1. Contributes to delayed diagnosis
  • Grading
  • AAST CT Grade for Splenic Injury
  1. Precautions
    1. May not accurately correlate with surgical findings
    2. Does not consistently predict the need for surgical intervention
  2. Grade 1
    1. Subcapsular hematoma <10% surface area OR
    2. Splenic Laceration <1 cm depth into parenchyma
  3. Grade 2
    1. Subcapsular hematoma 10-50% surface area OR
    2. Splenic Laceration 1-3 cm depth into parenchyma (not involving trabecular vessels)
  4. Grade 3
    1. Subcapsular hematoma >50% surface area or expanding OR
    2. Ruptured subcapsular or parenchymal hematoma OR
    3. Intraparenchymal hematoma >5 cm or expanding OR
    4. Splenic Laceration >3 cm depth into parenchyma OR
    5. Trabecular vessel involvement
  5. Grade 4
    1. Splenic Laceration involving segmental or hilar vessels with >25% splenic devascularization
  6. Grade 5
    1. Shattered Spleen OR
    2. Hilar vessel injury with complete splenic devascularization

  • Management
  • Surgery
  1. Indications: Emergent Surgery (to identify and control intraperioneal Hemorrhage)
    1. Hemodynamically unstable Trauma patient AND
    2. Positive FAST Scan or DPL
  2. Indications: Other findings despite hemodynamic stability
    1. High grade Splenic Injury (Grade 4 and especially Grade 5)
    2. Age over 55 years old
    3. Other serious comorbid injuries or illness and unlikely to tolerate Hypotension
    4. Generalized peritonitis
    5. Evidence for other intraabdominal injuries
    6. Refusal of Blood Products in the presence of severe Anemia (e.g. Jehovah Witness)
    7. Unreliable patient for serial abdominal examinations (e.g. Altered Level of Consciousness)
  3. Indications: Other findings that may be amenable to splenic embolization as an alternative instead of surgery
    1. Large volume hemoperitoneum
    2. Active radiocontrast extravasation
  • Management
  • Splenic Embolization
  1. Contraindications
    1. Hemodyanmic instability
    2. Surgical indications as above
  2. Indications
    1. Abdominal CT with contrast extravasation or blush
    2. Intraparenchymal pseudoaneurysm
    3. Large volume hemoperitoneum
  3. Protocol
    1. Intervention Radiology cannulates and embolizes via the Celiac Artery
      1. Access via brachial or femoral artery to the abdominal aorta
    2. Continue with nonoperative observation as below
  • Management
  • Nonoperative
  1. Contraindications
    1. Close medical and nursing monitoring not available
    2. Urgent or emergent surgical or embolization not available
    3. Hemodynamic instability
    4. Surgical interventions above
  2. Protocol
    1. Admit to Intensive Care unit (or other highly monitored hospital setting)
    2. Serial Hemoglobin every 6 hours for the first 24 hours
    3. Nothing by mouth for the first 24 hours
      1. May then eat when emergent surgery is unlikely
      2. Must first demonstrate stable Vital Signs and serial Hemoglobins
    4. Consider repeat Abdominal CT imaging
      1. Hemoglobin decrease (via trend or significant drop)
      2. Increased Abdominal Pain or left Shoulder Pain
      3. Fever
      4. Unreliable abdominal examination (e.g. Altered Level of Consciousness)
      5. Consider at 24-48 hours if high grade Splenic Injury (Grade 3 or higher)
    5. Indications for surgical intervention
      1. Continued Hemoglobin decrease or need for repeated Blood Transfusion
      2. Hemodynamic instability (e.g. Hypotension, persistent Sinus Tachycardia)
      3. Repeat imaging indicates further intervention
  3. Safety
    1. Initial non-operative management in stable patients with Grade 4-5 splenic Lacerations appears safe

  • Management
  • Follow-up
  1. See Asplenia
  2. Return to Play (Sports)
    1. Activity restriction for 3 months after injury
    2. Light Aerobic Activity allowed during recovery period
  3. Spleen expected to heal over 2 to 2.5 months
  4. Repeat imaging indications (not routinely performed)
    1. Recurrent left upper quadrant pain
    2. Referred Shoulder Pain
    3. Early satiety
