Splenic Contusion and Rupture
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.
Treatment
Pre-Hospital
-
Transport all patients with suspected splenic injuries to hospital for further evaluation.
-
Assess vital signs, and perform complete physical examination.
-
Assess for other injuries, especially in a trauma setting.
-
Obtain medical history, if possible.
-
If the patient is unstable, place 2 large-bore IVs, and begin fluid resuscitation.
-
Call ahead to advise ED/trauma team of clinical situation.
ED Treatment
-
Assess hemodynamic stability of patient.
-
Thorough trauma assessment and workup
-
Begin resuscitation as indicated clinically.
-
Type and screen or type and crossmatch in case transfusion is required.
-
Trauma surgery consultation
Medication
Consider not giving pain medications until after ED/trauma team initial evaluation.
Additional Treatment
General Measures
-
Emergent surgical consult and evaluation for all unstable patients with known or suspected splenic injury for consideration of emergency exploratory surgery and possible splenectomy
-
Admission for observation and management for all known splenic injuries
-
ICU admission for more severe splenic injuries or as indicated clinically
-
American Pediatric Surgical Association (APSA) Guidelines in Children with Isolated Spleen Injury Guidelines 2000 [B]: Guidelines for 5 parameters in management (excludes grade V injuries and unstable patients) (3).

P.547 -
*Return to full-contact, competitive sports should be at the discretion of the individual pediatric trauma surgeon. The proposed guidelines for return to unrestricted activity include “normal” age-appropriate activities (Stylianos, APSA Trauma Committee, 2000).
Referral
-
Surgical consultation is indicated for all suspected splenic injuries.
-
Consider referral to trauma center or pediatric trauma center for evaluation and management of suspected or known splenic injuries.
Surgery/Other Procedures
-
Consider emergency exploratory surgery for possible splenectomy for all hemodynamically unstable patients with known or suspected splenic injury.
-
Consider surgery for patients with known splenic injury whose clinical course is worsening.
-
Splenic artery embolization is being used in some trauma centers in some select patients (4).
-
Laparoscopic surgery, if surgery is to be performed, in the nonemergent patient may be considered.
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.
Complications
-
Possible reinjury or worsening of injury if return to activity too soon or if further trauma is sustained prior to full recovery
-
Unknown whether radiologic healing actually equals or translates to full physiologic healing
-
Delayed splenic rupture is main complication after nonoperative management of splenic injury. Occurrence rates vary from <1% to 2% in children and adults.
-
Delayed splenic rupture, if it occurs, has a 5–15% mortality rate (compared with the 1% mortality rate with primary splenic rupture) (8).
