전산화단층촬영에서 자동주입기에 의한 방사선 조영제의 혈관외유출(140mL)이 우측 손등의 IV 카테터 부위에서 발생하였다. 혈관외유출은 부종 및 괴사를 동반하였고, 구획증후군으로 발전하였다. 혈관외유출 부위를 MDCT로 스캔하여, 3D 재구성 영상인 MPR, MIP, volume rendering으로 재구성하였다. 이러한 3D 재구성 영상은 조영제의 혈관외유출 부위를 침범 정도를 정확하게 확인하여 환자 예방의 필요성 및 사후 조치에 적절한 치료 및 수술 계획에 유용하게 이용될 수 있다.
Radiographic contrast medium may cause tissue injury by extravasation during intravenous automated injection during CT examination. A large - volume extravasation (140 mL) occurred in an adult during contrast-enhanced CT The patient had a swelling and injury on the dorsum right hand of intravenous catheter region. The extravasation injury site was determined by CT scanning. The extavasation compartment syndrome case was examined using four separate display techniques. These 3D MDCT findings might help to determine the best course of treatment for patient with contrast extravasation. 3D image reconstructions provide accurate views of high-resolution and soft-tissue imaging. This paper introduces extravasation with the radiography and 3D MDCT findings.
