在穿支瓣手术中，精确定位穿支的可靠方法是非常有价值的。在这项研究中，我们尝试使用三维计算机断层血管造影（CTA），一种新开发的应用程序和平板设备来定位穿孔器的位置。在小型猪身上进行了测试该装置的初步检查。我们使用了5头雌性迷你猪。术前经颈内静脉注射碘帕美（200ml），俯卧位行CTA血管造影。在检查之前，我们在迷你猪的背上放了圆形标记。为了评估准确性，我们比较了用光学位置测量装置获得的穿孔位置和用片剂装置获得的穿孔位置。此外，我们将穿孔器的位置与我们直接测量的平板导航装置进行了比较。我们用光学位置测量装置测量了12个穿孔孔。平均差异为10 mm（最小2 mm，最大20 mm）。我们用平板导航设备测量这些穿孔。平均差5.4 mm（最小0 mm，最大20 mm）。将穿支皮瓣安全抬高。使用我们的设备可以安全地提升穿支皮瓣，因为平均差值仅为10毫米，这对于导航穿支皮瓣是可以接受的。猪背呈三角形；因此，我们无法在对侧放置标记。因此，对于设备的临床应用，我们应该确定理想的标记位置。
A reliable method for precise perforator mapping can be extremely valuable in perforator flap surgery. In this study, we attempted to map perforator location using 3-dimensional computed tomography angiography (CTA), a newly developed application, and a tablet device. Preliminary examinations to test the device were conducted in mini-pigs. We used 5 female mini-pigs. Preoperative imaging of the vasculature was undertaken with CTA in the prone position, following Iopamidol (200 ml) injection via the internal jugular vein. Prior to the examination, we placed round markers on the backs of the mini-pigs. To assess accuracy, we compared the perforator positions acquired with an optical position measurement device with the perforator positions acquired with the tablet device. Furthermore, we compared the perforator positions with the tablet navigation device, which we measured directly. We measured 12 perforators with the optical position measurement device. The mean difference was 10 mm (minimum, 2 mm; maximum, 20 mm). We measured these perforators with the tablet navigation device. The mean difference was 5.4 mm (minimum, 0 mm; maximum, 20 mm). The perforator flaps were elevated safely. The perforator flaps could be elevated safely using our device, as the mean difference was only 10 mm, which is acceptable for navigating perforator flap operations. Pig backs are triangular in shape; therefore, we were unable to place markers on the contralateral side. Thus, for clinical applications of the device, we should determine the ideal marker locations.
