Abstract
The purpose of this study was to analyze the impact of more selective use of admission angiography combined with protocolized nonoperative management for blunt splenic injury. This was a retrospective chart review of all patients with splenic injuries and Injury Severity Score < 20 managed by protocol and comparison with a prior matched group managed with admission angiography. Forty-three patients were managed under the protocol, with 22 patients treated with admission angiography and the remainder undergoing observation only. Nonoperative salvage was 100% in this group, with a length of stay of 3.3 days. The matched, nonprotocol group had a nonoperative salvage rate of 95%, with a length of stay of 6.8 days. Protocol-driven management of splenic injury using admission angiography selectively for higher grade splenic injuries led to a decreased length of stay, higher therapeutic yield, and decreased use of hospital resources without any increase in the failure rate of nonoperative management in a selected group of patients with isolated splenic injuries.
