Emergent interventional embolization for concealed hemorrhage of small artery injury in patients with pelvic fracture / 中国介入影像与治疗学

ABSTRACT

Objective :To explore the clinical value of emergent interventional embolization in treatment of concealed hemorrhage of small artery injury in patients with pelvic fracture. Methods Clinical data of 14 patients with concealed hemorrhage of small artery injury caused by pelvic fracture were retrospectively analyzed. All patients underwent emergent interventional embolization with gelatin sponge particles and micro-coils. Results There was no obvious contrast staining or accumulation in 14 patients. In the delayed phase, a total of 34 small arteries with slight staining were found. Obvious contrast media spillover signs were found with superselective catheterization. The hemostasis was successful after interventional embolization. Two patients died of hemorrhagic shock, severe acidosis and multiple organ failure after treatment. Conclusion: Superselective interventional embolization is an effective hemostatic measure for concealed hemorrhage of small artery injury in patients with pelvic fracture. Delayed phase angiography can improve the detection rate of small artery injury.
