We performed a pilot study to identify the predictive value of catheter-based computed tomography angiography (C-CTA) and traditional CTA (T-CTA) in ALT perforator mapping for patients whose ALT perforators were difficult to identify.<\/jats:p><jats:p>\n            Methods\u2003Thirty-four consecutive T-CTA\/C-CTA-mapped ALT flaps were evaluated for extremity reconstruction. The perforator location, origin, and course were compared between T-CTA\/C-CTA imaging and intraoperative findings. The mapping efficiency of T-CTA and C-CTA was compared thoroughly.<\/jats:p><jats:p>\n            Results\u2003Among the 34 ALT thigh flaps, 117 (36) of the 130 perforators identified intraoperatively were visible on C-CTA (T-CTA) in a subgroup of Chinese limb trauma patients with limited activity. C-CTA showed a satisfactory efficiency in perforator mapping, which was much better than the efficiency of T-CTA. C-CTA also showed a much better sensitivity (90.00 vs. 27.69%), specificity (94.74 vs. 66.67%), and accuracy (91.07 vs. 36.69%), and a much lower false-positive (1.68 vs. 26.53%), and false-negative rate (10.00 vs. 72.31%). Moreover, C-CTA could accurately predict the origin and septocutaneous or intramuscular course in all identified perforators. All flaps were elevated successfully and survived.<\/jats:p><jats:p>\n            Conclusion\u2003C-CTA outperforms T-CTA in the preoperative perforator mapping of ALT flaps in a subgroup of Chinese limb trauma patients. C-CTA should be the method of choice for perforator mapping in patients whose ALT flaps are intended for extremity reconstruction.<\/jats:p>","DOI":"10.1055\/s-0038-1672129","type":"journal-article","created":{"date-parts":[[2018,10,2]],"date-time":"2018-10-02T18:45:57Z","timestamp":1538505957000},"page":"221-228","source":"Crossref","is-referenced-by-count":16,"title":["Catheter-Based Computed Tomography Angiography in Anterolateral Thigh Perforator Mapping of Chinese Patients"],"prefix":"10.1055","volume":"35","author":[{"given":"Zhongjie","family":"Wang","sequence":"first","affiliation":[{"name":"Department of Neurology, Central South University, Xiangya Hospital, Changsha, People's Republic of China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jiqiang","family":"He","sequence":"first","affiliation":[{"name":"Department of Hand and Microsurgery, Xiangya Hospital of Central South University, Changsha, People's Republic of China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Liming","family":"Qing","sequence":"first","affiliation":[{"name":"Department of Hand and Microsurgery, Xiangya Hospital of Central South University, Changsha, People's Republic of China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhengbing","family":"Zhou","sequence":"first","affiliation":[{"name":"Department of Hand and Microsurgery, Xiangya Hospital of Central South University, Changsha, People's Republic of China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Youming","family":"Zhang","sequence":"first","affiliation":[{"name":"Department of Radiology, Central South University, Xiangya Hospital, Changsha, People's Republic of China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhiming","family":"Zhu","sequence":"first","affiliation":[{"name":"Department of Radiology, Central South University, Xiangya Hospital, Changsha, People's Republic of China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chunhui","family":"Zhou","sequence":"first","affiliation":[{"name":"Department of Radiology, Central South University, Xiangya Hospital, Changsha, People's Republic of China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hui","family":"Xie","sequence":"first","affiliation":[{"name":"Department of Radiology, Central South University, Xiangya Hospital, Changsha, People's Republic of China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xuejun","family":"Li","sequence":"first","affiliation":[{"name":"Department of Neurology, Central South University, Xiangya Hospital, Changsha, People's Republic of China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chishing","family":"Zee","sequence":"first","affiliation":[{"name":"Department of Radiology, Keck Medical Center of USC, Los Angeles, California, United States"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bihong","family":"Chen","sequence":"first","affiliation":[{"name":"Department of Diagnostic Radiology, City of Hope National Medical Center, Duarte, California, United States"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiaoping","family":"Yi","sequence":"additional","affiliation":[{"name":"Department of Radiology, Central South University, Xiangya Hospital, Changsha, People's Republic of China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"194","published-online":{"date-parts":[[2018,10,2]]},"container-title":["Journal of Reconstructive Microsurgery"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/www.thieme-connect.de\/products\/ejournals\/pdf\/10.1055\/s-0038-1672129.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2019,3,1]],"date-time":"2019-03-01T19:04:49Z","timestamp":1551467089000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.thieme-connect.de\/DOI\/DOI?10.1055\/s-0038-1672129"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2018,10,2]]},"references-count":0,"journal-issue":{"issue":"03","published-online":{"date-parts":[[2019,3,1]]},"published-print":{"date-parts":[[2019,3]]}},"URL":"https:\/\/doi.org\/10.1055\/s-0038-1672129","relation":{},"ISSN":["0743-684X","1098-8947"],"issn-type":[{"value":"0743-684X","type":"print"},{"value":"1098-8947","type":"electronic"}],"subject":[],"published":{"date-parts":[[2018,10,2]]}}}
