When acute arterial bleeding was encountered, the speedy hemostasis with the selective catheterization is usually requested.
Aortography is sometimes effective to detect the hemorrhage but not always good for catheter treatment strategy because
of the overlapping of the artery responsible to hemorrhage with the other non-responsible artery and the organs. If selective
catheterization were conducted to the untargeted artery, repeated arteriography using voluminous contrast medium would be
necessary, leading to time taking. Instead of aortography, a hemorrhage-responsible arteriogram created by 64-multidetector row
CT during aortography (CTAo) can play roles of hemorrhage mapping and catheter navigation. Of the seventy one cases with
the suspicious acute arterial bleeding, CTAo depicted hemorrhage in 61 cases and each hemorrhage-responsible arteriogram
contributed to navigate the catheterization, leading to the successful embolization. As advantages, CTAo depicted the arteries
responsible to hemoptysis not only from the bronchial arteries but also from the other systemic arteries such as internal thoracic
artery, lateral thoracic artery, inferior phrenic artery, and so on, at one time scanning. Further CTAo was especially useful for
acute arterial bleeding in the pancreatic arcade area supplied from both of celiac artery and superior mesenteric artery. In case
of the pelvic hemorrhage, CTAo could identify an artery responsible to hemorrhage from overlapped visceral arteries branched
from internal iliac arteries. In conclusion, a hemorrhage-responsible arteriogram created by 64 MDCT immediately before
catheterization was useful to create catheter treatment strategy for acute arterial bleeding.
