A 40-year-old man presents after a high-speed motor vehicle accident. CT abdomen shows a grade IV splenic laceration (laceration >3 cm depth involving hilar vessels; devascularization >25% of spleen) with active extravasation. BP is 110/70 mmHg after 1L fluid resuscitation. The MOST appropriate management per WSES 2020 guidelines for hemodynamically stable grade IV blunt splenic injury in adults is:
- A Emergency splenectomy to prevent delayed rupture
- B Conservative management with observation in ICU, no angiography
- C Angioembolization (proximal or selective) as the first-line intervention ✓
- D Damage control surgery with splenic packing
Explanation
WSES 2020 guidelines for blunt splenic injury in hemodynamically stable patients recommend non-operative management (NOM) for grades I-V when patients are hemodynamically stable. For grade IV (high injury grade with active extravasation), angioembolization is the key adjunct to NOM — it significantly reduces failure rates from ~25% to ~5-10% for high-grade injuries. Proximal embolization reduces overall splenic perfusion pressure; selective embolization targets specific bleeding vessels. Surgery (splenectomy) is reserved for hemodynamic instability despite resuscitation or NOM failure. Observation alone without angioembolization for grade IV with active extravasation is inadequate.
