Introduction:
Evaluate outcomes and radiation exposure across different splenic artery embolization (SAE) techniques for splenic injuries secondary to blunt trauma.
Methods:
This retrospective cohort study included patients 18 years of age or older who underwent SAE for splenic injury after blunt trauma from January 2011 to June 2019.
Results:
Sixty patients underwent angiography for splenic injury after blunt traumatic injury. Forty-four patients were embolized. Seventeen patients underwent proximal SAE, and 23 underwent distal SAE. Four patients had a combination of proximal and distal SAE. Eleven patients had subsequent major complications requiring splenectomy. There was no significant difference in major complication rate when comparing proximal SAE 29.4% versus distal SAE 21.7%. No significant difference was noted across the two groups with respect to age or grade of injury. There was a statistically significant difference (P = 0.004) in fluoroscopy time between the proximal 10.1 ± 4.2 min and distal group 17.8 ± 8.7 min. No statically significant difference was found in major complications when comparing coil versus gel foam embolization.
Conclusion:
Proximal SAE is associated with a significantly lower fluoroscopy time (P = 0.004). Complication rates are similar after proximal and distal SAE. No significant difference was found in major complication rates comparing coil versus gel foam embolization. Minor complications more commonly occurred after proximal embolization with gel-foam.
