Three-dimensional spiral computed tomographic angiography: An alternative imaging modality for the abdominal aorta and its branches

摘要: Abstract Purpose:  We sought to apply a new technique of computed tomographic angiography (CTA) the preoperative and postoperative assessment abdominal aorta its branches. Methods:  After peripheral intravenous contrast injection, patient is continuously advanced through spiral CT scanner, while maintaining 30-second breath-hold. Thirty-five patients with aortic, renal, visceral arterial disease have undergone CTA. Results:  Diagnostic three-dimensional images were obtained in aortic aneurysms ( n = 9), dissections 4), mesenteric artery stenoses 4). The has also been used assess vessels after operative reconstruction or endovascular intervention 18 patients. These preliminary studies correlated well conventional arteriographic findings. In aneurysmal both lumen mural thrombus associated renal are visualized. true false channels perfusion source clearly shown; patency stent placement confirmed. CTA relatively noninvasive can be completed less time than radiation exposure. Conclusions:  This initial experience suggests that may valuable alternative arteriography evaluation (J VASC SURG 1993;18:656-65.)
