Abstract

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.

体重指数与计算机断层血管造影在股前外侧皮瓣移植血管定位中的相关性。

目的:探讨身体质量指数(BMI)与计算机断层血管造影(CTA)在股前外侧穿支皮瓣(ALT)血管定位中的相关性，并以BMI为变量探讨CTA对ALT血管定位的影响。方法:收集我院(无锡市第九人民医院)2017年1月至2019年5月因肢体损伤住院并需要进行ALT移植的患者117例。根据BMI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定位三组股骨前外侧(ALT)皮瓣的穿支血管。收集所有手术和CTA数据。结果:BMI与CTA定位有显著正相关(P < 0.05)。结论:BMI越大，CTA定位越准确。当BMI不小于18.5时，CTA定位最准确。
