“…[6][7][8][9] In addition, the high cost associated with the procedure limits its availability in some hospitals. [6][7][8][9] Tsukino et al reported that all the points identified with the CDU for the anterolateral thigh perforator coincided with the actual perforators and there were no misidentifications or missed arteries. Their concordance rate was 100%.…”

“…15 Recently, for planning and designing of the various perforator flaps, the CDU has been the most commonly used method of preoperative perforator mapping, providing predictive information regarding the blood-flow characteristics of the cutaneous perforators. [6][7][8][9] The CDU is noninvasive and effective for evaluating the location, number, depth and course of cutaneous perforators, although the disadvantage is that it requires the experienced examiner and the learning curve to be skilled at detecting the perforators.

Purpose: The second dorsal metacarpal (SDMC) perforator flap has been widely used for the soft tissue reconstruction of the hand. However, it is difficult to identify the depth and branches of the perforators of the second dorsal metacarpal artery (SDMA) using only handheld acoustic Doppler flowmetry (HADF), which is the most common method. The purpose of this study was to compare the results of examination by color Doppler ultrasonography (CDU) with those of HADF and to evaluate the efficacy of CDU for detection of the perforators to be used in the design of the SDMC flap. Methods: Twenty-two healthy volunteers (42 hands) were examined using both CDU and HADF. All locations identified as the perforators of the SDMA by the two examinations were mapped respectively. Results: The total perforator arteries detected with CDU in all hands were 111 branches, 49 branches of which could not be identified with HADF. The average number of perforators of the SDMA per hand found with CDU was 2.8 branches, while that for HADF was only 1.8 branches. The detection rates of the cutaneous perforators of the SDMA by CDU were 100% in the proximal onethird of the second metacarpal and 95% in the distal one-fourth of the second metacarpal. Conclusion: This study demonstrated the superiority of CDU compared with HADF for detection of the perforators of the SDMA. The CDU examination could easily identify the locations of the cutaneous perforators and help in the useful assessment of vascularity for the SDMC flap.
