Abstract

Abstract: Objective:To investigate the applicative value of CT angiography in the clinical designing of vascularized iliac crest flap. Methods:From August 2014 to September 2015,12 patients with mandibular defects were treated with vascularized iliac crest flap. Preoperative CTA was conducted. Imaging workstation (Philips Medical System) was used to observe and measure the diameter of deep circumflex iliac artery (DCI) at the starting point,the angle between the starting segment of DCI and the line from one anterior superior iliac spine to the other,and the length from the starting point of DCI to anterior superior iliac spine. The body surface location of the starting point of DCI was determined according to the angle and the length,and then iliac crest flap harvesting was simulated. Results:The diameter of DCI at the starting point was (2.8±0.61) mm,the angle and the length were (55±1.7) degree and (65.1±1.24) mm, respectively.Iliac crest flap harvesting was simulated successfully according to the reconstructed image. Conclusion:CTA can accurately determine the anatomical location of DCI,and it can effectively guide the designing of the iliac crest flap.
