RESUMEN
Objective To investigate the clinical application value of selective arterial embolization in the treatment of iatrogenic hemorrhage.Methods 32 cases with iatrogenic hemorrhage were retrospectively analyzed.The location and feature of bleeding were identified by selective percutaneous artery angioraphy,and then super-selective interventional embolization were performed.The embolic agents inclued gelfoam medical line,steel coils or polyvinyl alcohol (PVA)particles.Results In 32 patients,26 cases with active bleeding signs were found by angiography,they mainly presented contrast medium overflow,6 cases with pseudo-aneurysms,1 case with ar-teriovenous fistula.All patients underwent interventional embolization successfully.Only 1 case underwent twice procedure because of rehaemorrhagia on the 8 days after embolization.Follow-up for a month after arterial embolization,25 cases had no severe compli-cations,1 case died by multiple organ failure.In 6 negative cases,3 cases died by hemorrhagic shock,3 cases stopped hemorrhage after medical treatment.Conclusion Selective angiography is a safe and effective measure for the treatment of iatrogenic hemor-rhage.
