Splenic Contusion and Rupture
Eugene Hong
Basics
Description
  • Splenic injury spectrum includes contusion, hematoma, laceration, and rupture.
  • Not uncommon in contact and collision sports or with falls during activities, including football, hockey, lacrosse, biking, skiing, horseback riding, and motorsports.
Epidemiology
  • Most common abdominal organ injury in sports (1)
  • May represent up to 50% of all sports-related abdominal organ injuries
  • 1.5 million adults are admitted to hospitals each year in the U.S. following an injury; ∼2.6% will have a blunt splenic injury (2).
Risk Factors
  • Recent or distant history of trauma that may have caused a prior splenic injury that did not completely resolve (see “Delayed splenic rupture” in “Complications” section below)
  • Overlying rib fracture
  • Recent infectious mononucleosis infection resulting in splenomegaly
Etiology
Trauma mechanism resulting in direct or indirect force on the spleen
Commonly Associated Conditions
  • Liver injury
  • Rib injury
  • Kidney injury
Diagnosis
History
  • Symptoms of hypovolemia: Dizziness, light-headedness, syncope, palpitations, shortness of breath
  • Abdominal pain: May be localized to left upper quadrant
  • Left shoulder pain: Referred via the left phrenic nerve from intraabdominal diaphragmatic irritation (Kerr sign)
  • Pain elsewhere also should raise suspicion for concurrent injuries elsewhere, eg, liver, rib, kidney.
Physical Exam
  • Vital signs including orthostatics: Serial measurements; assess for stability; relative tachycardia may be an early sign.
  • Abdominal tenderness
  • Abdominal rebound or guarding, consistent with peritoneal irritation from bleeding
  • Decreased or absent bowel sounds
  • Avoid palpating spleen aggressively or deeply.
  • Decreased breath sounds
  • Rib tenderness, crepitus, or deformity
  • Costovertebral angle tenderness
  • Skin discoloration in the periumbilical area (Cullen sign) or flank (Turner sign) may take 24 hr to appear; both signs are consistent with intra-abdominal bleeding.
Diagnostic Tests & Interpretation
Lab
  • CBC
  • Type and screen or type and crossmatch in the event that a transfusion is needed.
  • Serum electrolytes
  • Consider serial hemoglobin/hematocrits as indicated clinically.
Imaging
  • Consider abdominal CT scan if splenic injury suspected.
  • US may not be as sensitive as CT scan in determining severity in splenic injury.
  • Imaging results will help to assess for the presence and severity of splenic injury.
  • Severity grading will help to guide management by the American Pediatric Surgical Association (APSA) Guidelines 2000.
  • American Association for the Surgery of Trauma Splenic Injury Scale (revised 1994):
    • Grade I:
      • Hematoma, subcapsular: <10% surface area
      • Laceration, capsular tear: <1 cm parenchymal depth
    • Grade II:
      • Hematoma, subcapsular: 10–50% surface area, intraparenchymal, <5 cm diameter
      • Laceration, capsular tear: 1–3 cm parenchymal depth; does not involve trabecular vessel
    • Grade III:
      • Hematoma, subcapsular: >50% surface area or expanding; ruptured subcapsular or parenchymal hematoma; intraparenchymal hematoma >5 cm or expanding
      • Laceration: >3 cm parenchymal depth or involving trabecular vessels
    • Grade IV: Laceration: Involving segmental or hilar vessels producing major devascularization (>25% of spleen)
    • Grade V:
      • Laceration: Completely shattered spleen
      • Vascular: Hilar vascular injury that devascularizes spleen
  • Advance 1 grade for multiple injuries up to grade III.
Ongoing Care
  • If splenectomy is performed, patient will need pneumococcal [A], meningococcal [B], and Haemophilus influenzae (Hib) [B] vaccines; give at or after 14 days for emergency splenectomy, and consider boosters every 5 yrs (5). Also, CDC recommends annual influenza vaccination in the asplenic population.
  • Need for follow-up imaging is controversial in the clinically improving patient with a nonoperatively managed isolated splenic injury. In pediatric patients engaged in normal age-appropriate activities, follow-up imaging may not be needed after isolated splenic injury (6)[C]. Further research studies may be required to determine if serial imaging is needed, and when, before acceptable return to contact and collision sports.
  • If indicated clinically, consider follow-up or serial imaging with abdominal CT scan in any age group.
  • Nonoperative management of stable isolated splenic injuries is appropriate in the majority of patients.
  • 95–99% of pediatric patients with stable isolated splenic injury grades I–IV can be managed nonoperatively (7).
  • 70–90% of adult patients with stable isolated splenic injuries can be managed nonoperatively.
  • Prior recommendation for return to play was 3 mos, in part based on studies looking at radiographic healing in splenic injuries.
  • For return to play in pediatric patients, see APSA Guidelines 2000 in “Treatment” section above.
  • There are no return-to-play guidelines similar to the APSA Guidelines for the adult population; it may be reasonable to use APSA Guidelines in this population as well.
  • As noted in the APSA Guidelines, return to play for full-contact and collision sports should be based on the individual clinical case and in discussion with the treating physician.
Codes
ICD9
