A 28-year-old man presents to the emergency department following a motor vehicle collision with left-sided rib fractures and left flank contusion. FAST examination reveals the structure marked **A** (hypoechoic subcapsular splenic hematoma) on the splenorenal view. The patient is hemodynamically stable with normal vital signs and no peritoneal signs. CT with IV contrast confirms AAST Grade II splenic injury without contrast extravasation or pseudoaneurysm. What is the most appropriate management strategy for this patient?
A. Non-operative management with admission to ICU/HDU, bed rest, serial vital signs, and hematocrit monitoring
B. Observation in the outpatient clinic with follow-up ultrasound in 1 week
C. Urgent splenic artery angioembolization
D. Immediate laparotomy with splenectomy
Explanation
Why Non-operative management with admission to ICU/HDU, bed rest, serial vital signs, and hematocrit monitoring is right
The clinical anchor states that hemodynamically stable patients with AAST Grade I–III splenic injuries without contrast extravasation or pseudoaneurysm are candidates for non-operative management (NOM). This patient meets all criteria: stable hemodynamics, Grade II injury (subcapsular hematoma 10–50%), and no imaging signs of vascular injury. The structure marked A (hypoechoic subcapsular hematoma) is the hallmark of Grade I–II injury, which carries a high success rate for NOM when managed with ICU/HDU admission, bed rest, NPO status initially, serial vital signs, and transfusion as needed. This approach preserves splenic function and avoids post-splenectomy immunocompromise.
Why each distractor is wrong
Immediate laparotomy with splenectomy: Reserved for hemodynamic instability unresponsive to resuscitation, peritonitis, or failure of NOM. This stable Grade II patient has no indication for operative intervention.
Urgent splenic artery angioembolization: Indicated only for contrast extravasation (blush), pseudoaneurysm, Grade IV–V injuries in stable patients, or declining hematocrit despite resuscitation. This patient has no contrast blush and Grade II injury.
Observation in the outpatient clinic with follow-up ultrasound in 1 week: Grade II splenic injury requires ICU/HDU admission for continuous monitoring, not outpatient observation. Risk of delayed hemorrhage necessitates inpatient surveillance.
