Abstract

CASTRO GARCIA, J. et al. Analysis of deep inferior epigastric perforating vessels with 3D CT angiography, color Doppler ultrasonography and Doppler in diep flaps: preliminary results. Cir. plást. iberolatinoam. [online]. 2008, vol.34, n.3, pp.223-234. ISSN 1989-2055.

The aim of this report, is to validate the Angio-CT technique with three-dimentional reconstruction as a preoperative planning tool, after comparison with Doppler ultrasound and color- Duplex. Between january 2006 and march 2007, we studied 11 consecutive patients (13 DIEP) in whom a prospective comparative followed up was performed comparing, the findings observed using Doppler ultrasound, Colour-Duplex and Angio-CT with three-dimentional reconstruction. Surgical procedure findings were considered as the reference value. The evaluation procedure included the election of the most suitable perforator vessels, taking account of the location, caliber and anatomical relationships with the muscle. The Angio-CT with three-dimentional reconstruction showed 100% specificity (CI 95% 75.3-100), and very high positive predictive value. In this way, this technique could be considered as an excellent tool for preoperative evaluation of perforators flaps. Color-Duplex showed that in 46,1% of the patients (CI 95% 19,2-74%) the selected perforator matched with the intraoperatively selected. Using Doppler ultrasound only in 30,8% of the cases (IC 95% 9,1-61,4%) this result was observed. In this report, Angio-CT with three-dimentional reconstruction has revealed as a very high specificity technique, that allows a great account of important information, only comparable with anatomical dissection and ahead from Doppler ultrasound and color-Dupplex.
