CT-ANGIOGRAPHY OF ABDOMINAL AORTIC-ANEURYSMS AFTER TRANSFEMORAL ENDOVASCULAR ANEURYSM MANAGEMENT

Objective: To evaluate short-term effect of transfemoral Endovascular Aneurysm Management (TEAM) on aortic diameters and volumes after aneur ysm exclusion, using CT-angiography. Design: Analysis of preoperative, 1 week postoperative and 6 months postoperative CT measurements. Sett ing: University Hospital. Materials: Nine patients treated with an end ovascular tube prosthesis. Chief outcome measures: True cross-sectiona l diameters of the aorta and the aneurysm, volume of the infrarenal ao rtic lumen, of the thrombus and of the iliac arteries and length of th e aorta and of the endovascular prosthesis. Main results: CT-angiograp hy detected shrinkage of the aneurysm in seven patients. Aneurysm grow th was observed in one patient with persistent pow outside the graft a nd in one patient with fully thrombosed aneurysm sac. In the two patie nts with increasing thrombus volume, the volume of the aortic lumen de creased. Conclusion: Although successful aneurysm exclusion can be con firmed by maximum aneurysm diameter measurement, changes in aortic lum en volume and thrombus volume may be more appropriate to discriminate successful from failed exclusion.
