Abstract
Purpose
This study was designed to evaluate the clinical success, complications, and transfusion requirements based on the location of and agents used for splenic artery embolization in patients with splenic trauma.
Methods
A retrospective study was performed of patients with splenic trauma who underwent angiography and embolization from September 2000 to January 2010 at a level I trauma center. Electronic medical records were reviewed for demographics, imaging data, technical aspects of the procedure, and clinical outcomes.
Results
Fifty patients were identified (34 men and 16 women), with an average age of 48 (range, 16–80) years. Extravasation was seen on initial angiography in 27 (54%) and was absent in 23 (46%). All 27 patients with extravasation were embolized, and 18 of 23 (78.2%) without extravasation were embolized empirically. Primary clinical success was similar (>75%) across all embolization locations, embolic agents, and grades of laceration treated. Of 45 patients treated, 9 patients (20%) were embolized in the main splenic artery, 34 (75.6%) in the splenic hilum, and 2 (4.4%) were embolized in both locations. Partial splenic infarctions developed in 47.3% treated in the splenic hilum compared with 12.5% treated in the main splenic artery. There were four (8.9%) mortalities: two occurred in patients with multiple critical injuries and two from nonbleeding etiologies.
Conclusions
Embolization of traumatic splenic artery injuries is safe and effective, regardless of the location of treatment. Embolization in splenic hilar branches may have a higher incidence of infarction. The grade of laceration and agents used for embolotherapy did not impact the outcomes.
