IV-DSA as a screening study before conventional transarterial angiography

Twenty patients with hepatic mass underwent IV-DSA by Ioversol. IV-DSA revealed useful information about whether or not intra-arterial angiography could be peformed quickly and safely, because IV-DSA revealed beforehand the degree of arteriosclerotic change and presence of aneurysm of the abdominal aorta and pelvic artery. IV-DSA revealed the existence of complications due to transarterial angiography in the past. IV-DSA should be performed as a mapping study before conventional angiography in the future. Because IV-DSA was easily influenced by misregistration artifact due to bowel gas movement in the abdomen and pelvic portion, diagnosis should be made with care. There was no occurrence of early or delayed side effects due to the new nonionic contrast medium Ionversol. (author)
