Letter REPLY Re: “Endovascular Treatment of a Symptomatic Thoracoabdominal Aortic Aneurysm by Chimney and Periscope Techniques for Total Visceral and Renal Artery Revascularization”
We appreciated the comments about the saccular pseudoaneurysm originating from the fusiform abdominal aneurysm in the Letter to the Editor from Canyigit et al. . We agree with the comment of Canyigit et al.  that this kind of pathology is extremely rare and that penetrating atherosclerotic ulcer is the most likely underlying mechanism of its formation . Contrast-enhanced multidetector computed tomography (MDCT) has become the technique of choice to evaluate aortic disease for its specificity, sensibility, and availability .
To our knowledge, the total number of described saccular pseudoaneurysms originating from the fusiform abdominal aneurysm has increased to six cases in total [1, 3, 4]. In our previous paper, we have not emphasized this pathological aspect, because the focus of the case report was on revascularization . However, on MDCT follow-up after endovascular treatment the pseudoaneurysmatic sac showed a considerable reduction in volume .
