PURPOSE: To study the technical and clinical outcome of urgent transcatheter arterial embolization (TAE) for post-operative arterial complications after pelvic or hip surgery, and to accumulate additional experience about the role of embolisation for these injuries.


METHODS: Patients receiving TAE procedure for arterial complications after pelvic or hip surgery were searched and enrolled. Retrieval was based on medical records between 1st September 2002 and 1st December 2014. Angiographic findings included active contrast agent extravasation, pseudoaneurysm formation, arteriovenous fistula, and other suspicious signs. Other suspicious signs were defined as sight coarse margin or distortion of vessels. Embolic agents consist of coils, gelatin sponge and polyvinyl alcohol. Technical success was defined as complete cessation of targeted artery through angiography, and clinical success as sustained cessation of symptoms.


RESULTS: A total of 22 patients (15 males, 19–76 years old) were enrolled. Prior to TAE, 12 patients developed to hemorrhagic shock and the remaining 10 patients had hemorrhage-related pain, hematoma, or anemia. Contrast agent extravasation occurred in 12 cases, pseudoaneurysm formation in 5 cases and other suspicious signs in 5 cases. The most injured vessels were internal iliac artery stem in 6 cases, inferior gluteal artery in 6 cases and superior gluteal artery in 6 cases. Multiple vascular lesions appeared in 5 cases. After TAE, technical success occurred in 22 patients, and clinical success in 21 patients (95.5%). A 36-year-old woman died of irreversible multiple organ failure and no other severe procedure-related complications were recored.


CONCLUSION: TAE is safe and effective for post-operative arterial complications after pelvic or hip surgery.
