Laboratory findings were as
follows: hemoglobin 6.7 g/dL; international normalized ratio (INR) 3.2; because he was on the oral anticoagulation LOXO-101 nmr therapy for aterial fibrillation with warfarin and asprin. Arterial blood gas analysis revealed acute respiratory failure with a pH value of 7.344, PaO2 of 61.5 torr, PaCO2 of 49.0 torr under 5 L/min of oxygen supplementation by face mask. His urinary bladder pressure equal to intraabdominal pressures (IAP) was 26 cmH2O. He became hemodynamically unstable with hypotension. Transfusion of fresh frozen plasma and packed red blood cells was followed by a fluid overload and vitamin K. And he was placed on ventilator. Ultrasonography detected a hemoperitoneum and liver laceration. Enhanced computed tomography (CT) showed that contrast material extravasation MLN2238 was in the hepatic hilum on arterial phase (Figure 1a), and an uncovered laceration extended over segments 1, 4 and 8 of the liver with massive hemoperitoneum (Figure 1b,c). There were associated several rib fractures in the right upper quadrant and mild right hemothorax. Finally, we diagnosed
as primary ACS. However, surgeons hesitated to perform laparotomy because of his hemorrhagic diathesis, therefore TAE was initially selected. The celiac artery was quickly cannulated with a 5-Fr shephered hook catheter (Clinical Supply Co. Ltd., Gifu, Japan). Digtal subtraction angiography (DSA) of the celiac artery demonstrated the perforated left hepatic arterial branch with exravasation (Figure 2a). The right hepatic artery was replaced on the superior mesenteric artery without extravasation. 2.0-Fr BI 6727 mw coaxial microcatheter (Progreat, Terumo Corp., Tokyo) was advanced nearby the bleeding point of the left hepatic arterial branch using a 0.014-in. microguidwire Lepirudin (Transend EX, Boston Scientific Corp., Watertown, MA, USA) (Figure 2b). Embolizaion was performed using mixtures of 0.1 mL of N-Butyl Cyanoacylate
(NBCA) and 0.5 mL of Lipiodol. After TAE, DSA did not demonstrate extravasation (Figure 2c,d) and the patient became hemodynamically stable. Under ultrasonographic guidance, we inserted a 10.2-Fr pigtail drainage catheter (Cook Inc., Bloomington, IN, USA) into the right paracolic gutter using Seldinger’s technique. At the same time, IAP measured with the pigtail catheter was 30 cmH2O. About 3.2 L of intra-abdominal blood was evacuated through the pigtail catheter for the next two hours. IAP dropped to 12 cmH2O. He was discharged from the hospital without any major complications on 32 days after TAE. Figure 1 A 71-year-old man was admitted to emergency unit for abdominal trauma due to traffic accident. (a) CT showed that contrast material extravasation was in the hepatic hilum on arterial phase (arrow), and (b) an uncovered laceration extended over segments 1, 4 and 8 of the liver with massive hemoperitoneum.
