Added value of three-dimensional digital subtraction angiography, using dual-volume reconstruction technique, in post-treatment follow-up of cerebral aneurysms

Abstract

Abstract Background To assess the added value of the dual-volume technique when used with the routine single-volume 3D DSA in the follow-up of endovascularly treated aneurysms. Results Seventeen patients (10 females and 7 males) who underwent coiling of their cerebral aneurysms were assessed by 3D DSA using single- and dual-volume techniques. Recanalization of the aneurysm was depicted in 10 cases on the dual-volume technique, only 4 of which were detected on the single-volume 3D DSA technique. Thus, the use of the dual-volume technique upgraded our management plan from follow-up to re-treatment in 6 cases (35%) Conclusion The dual-volume technique of 3D DSA is superior to the single-volume technique in visualization of the endovascular devices distinctly, resulting in better evaluation of the aneurysm recanalization and its relation to the parent vessel and occluding device.
