Behrens, A. Modabber, C. Loberg, A. Herrler, A. Prescher, A. Ghassemi PurposeComputed tomographic angiography (CTA) is reported to give insight into patient-specific anatomy of the flap pedicle preoperatively. We compared information available from standard CTA (s-CTA) with that gained by modifying the conventional CTA technique (modified CTA [m-CTA]). Dissected cadavers served as the control group.Materials and MethodsWe evaluated 16 s-CTA scans (32 deep circumflex iliac arteries [DCIAs]) and 12 m-CTA scans (17 DCIAs) using 3-dimensional software (Vesalius; ps-medtech, Amsterdam, The Netherlands). We dissected 17 cadavers (n = 34) to serve as the control group. The positions of 4 landmarks (anterior superior iliac spine, origin of DCIA, origin of ascending branch, and crossing of horizontal branch and iliac crest) were defined in a 3-dimensional coordinate system.ResultsWe found significant differences concerning the distances from the origin of the DCIA to the femoral bifurcation (P .05) and the anterior superior iliac spine to the crossing point of the horizontal branch with the iliac crest (P .05) between CTA scans and cadaveric studies. The imaging quality of the m-CTA scans was shown to be more consistent than and superior to that of the s-CTA scans. The visible length of the DCIA was longer on m-CTA scans (mean, 134.32 mm) than on s-CTA scans (mean, 73.62 mm). We could evaluate the branching off of perforators and the relation of the pedicle to the surrounding bone and soft tissue in more detail on m-CTA scans. Standard CTA allowed the bilateral evaluation of the pedicle, whereas m-CTA allowed the evaluation of the injected side only.ConclusionsThe quality and quantity of information available from CTA could be improved by modifying the s-CTA examination by injection as close as possible to the target vessel. Standard CTA delivered information about both sides, whereas m-CTA may need an additional injection for contralateral-side imaging. - video upload powered by https://www.TunesToTube.com
