Complications arising from splenic embolization after blunt splenic trauma

Background Nonoperative management (NOM) of splenic trauma is now the standard in stable trauma patients. Splenic artery embolization (SAE) is an increasingly used adjunct to NOM. We examined complications arising from SAE. Methods Patients admitted to a level I trauma center with splenic trauma over a 26-month period were identified. Management method, operative or nonoperative, was noted. SAE patients were analyzed in detail. Results There were 284 splenic trauma admissions. Ninety-three patients underwent operative management, and 191 received NOM. Fifteen patients (7.8%) underwent SAE. Embolization was proximal in 10, distal in 1, and combined in 4 patients. No NOM failures occurred. Major complications (27%) included splenic bleeding, splenic infarction, splenic abscess, and contrast-induced renal insufficiency. Minor complications of fever, pleural effusions, and coil migration occurred in 53% of patients. No relationship between SAE location and the presence of complications was noted. Conclusions SAE is an effective and safe procedure. Both major and minor complications can arise after SAE.
