Spiral-CT Angiographie vor endovaskulärer Versorgung bei Patienten mit rupturiertem aortoiliakalem Aneurysma
2013
Background: To evaluate spiral computed tomography (SCT) angiography for assessment of feasibility of endovascular aneurysm repair (EVAR) in patients with ruptured aortoiliac aneurysm (AAA). Patients and methods: 24 patients (mean age 74 years; range, 69 to 82 years) with suspicion of ruptured AAA and stable hemodynamics were preoperatively examined by using a SCT scanner in the emergency room. SCT angiography was performed from the suprarenal aorta to the femoral bifurcation after a fixed injection delay time of 30 seconds. After that a venous phase SCT scan, beginning at the last image position and ending at the upper thoracic aperture, was performed. Results: The mean acquisition time of the SCT scan was 80 seconds (range 70 to 100 seconds), the mean overall procedure time, including image reconstruction, 5 minutes (range, 4 to 6 minutes). 2D images were directly evaluated during CT data acquisition, and 3D image reconstructions within 10 minutes (range, 8 to 11 minutes) after the SCT scan.
