Abstract
Interventional radiology (IVR) has increasingly been selected for traumatic hemorrhagic shock. N-butyl-2-cyanoacrylate (NBCA) is an effective measure for traumatic hemorrhage with coagulation abnormality due to the its property as a embolization material, independent of the patient’s individual clotting ability and the shorter embolization time.Two cases in which transcatheter arterial embolization (TAE) using NBCA was effective for traumatic hemorrhagic shock in patients with suspected coagulation abnormalities are reported. Case 1 was a man in his 70s who developed hemorrhagic shock following a pelvic fracture caused by a traffic injury. NBCA embolization of the right internal iliac artery was performed based on the results of the coagulation test and the possibility that oral administration of antiplatelet agents may increase the bleeding tendency. Case 2 was a woman in her 80s who developed hemorrhagic shock following a renal injury that was caused by a bruise on the right side of her abdomen. In addition, loss of the tamponade effect within the retroperitoneum was a concern due to the advanced age; therefore, NBCA embolization of the right renal artery was performed. In both cases, NBCA was effective. TAE using NBCA may be effective in cases at risk of fibrinolytic-type disseminated intravascular coagulation (DIC).
