OBJECTIVE
This work aimed to investigate the correlation between body mass index (BMI) and computed tomography angiography (CTA) in the vascular positioning of anterolateral thigh perforator flap (ALT) and to discuss the influence of CTA on the vascular positioning of the ALT by taking BMI as a variable.
METHODS
A total of 117 patients who admitted to our hospital (Wuxi Ninth People's Hospital) from January 2017 to May 2019, hospitalized due to limb injury and needed ALT transplantation were collected in this work. According to the BMI, the patients were divided into group A (BMI < 18.5) with 18 cases, group B (18.5 ≤ BMI < 24) with 56 cases, and group C (BMI ≥ 24) with 43 cases. CTA was used to locate the perforator vessels in anterolateral thigh (ALT) flap of the three groups. All surgical and CTA data were collected.
RESULTS
There was a significant positive correlation between BMI and CTA positioning (P < 0.05).
CONCLUSION
The larger the BMI, the more accurate the CTA positioning. When the BMI was not less than 18.5, CTA positioning should be the most accurate.
目的
本研究旨在探讨体重指数（BMI）与大腿前外侧穿支皮瓣（ALT）血管定位中计算机断层血管造影（CTA）之间的相关性，并以BMI为变量探讨CTA对ALT血管定位的影响。
方法
本研究收集了2017年1月至2019年5月在我院（无锡市第九人民医院）住院、因肢体损伤需要进行ALT移植的117例患者。根据BMI将患者分为A组（BMI<18.5）18例、B组（18.5≤BMI<24）56例、C组（BMI≥24）43例。采用CTA对三组患者大腿前外侧（ALT）皮瓣的穿支血管进行定位。收集所有手术及CTA数据。
结果
BMI与CTA定位之间存在显著正相关（P<0.05）。
结论
BMI越大，CTA定位越准确。当BMI不小于18.5时，CTA定位应最为准确。
