Abstract

The newly revised 2018 Organ Injury Scale (OIS) has a similar format to the previous American Association for Surgery and Trauma (AAST) Emergency General Surgery Grading System, dividing the criteria for grading solid organ damage into three groups; imaging, operation, and pathology. The most significant alteration in the OIS system 2018 revision is the incorporation of multidetector CT (MDCT) findings of vascular injury including pseudoaneurysm and arteriovenous fistula. Similar to the previous OIS, the highest of the three criteria is assigned the final grade. In addition, if multiple grade I or II injuries are present, one grade is advanced for multiple injuries up to grade III. This pictorial essay demonstrates the MDCT findings of solid organ injury grades based on the 2018 OIS system.

2018년에 새롭게 개정된 장기 손상척도는 이전 미국외상수술협회의 응급수술분류체계와 유사한 형식을 가지며, 고형장기 손상의 등급을 지정하는 기준을 영상(imaging), 수술(operative), 병리(pathologic) 세 가지 세트로 나누어 분류하였다. 2018년 개정에서 가장 중요한 변화는 거짓동맥류와 동정맥 누공을 포함한 혈관 손상의 다중검출CT (multidetector CT; 이하 MDCT) 소견을 정의하여 장기 손상척도에 통합한 것이다. 이전 장기 손상척도와 동일하게 세 가지 기준 중에 가장 높은 등급이 최종 등급이 된다. 또한 한 장기 내에 여러 개의 1등급 또는 2등급 소견이 있으면, 다발성 손상에 대해 3등급의 부여가 가능하다. 본 임상화보에서는 2018년 개정된 미국외상수술협회 장기 손상척도의 MDCT 소견을 소개하고자 한다.
