To evaluate the feasibility of transauricular arterial access and compare the procedure time needed for hepatic artery angiography via transfemoral versus transauricular arterial access in a rabbit model.
This study was approved by the research animal care and use committee. Twenty rabbits were divided into transfemoral (n = 10) and transauricular access groups (n = 10). The procedure consisted of shaving the hair, obtaining intraarterial access, performing hepatic artery angiography, and repairing the access site. A Mann-Whitney U test was used to compare the two groups in terms of the total procedure time and the time needed for each step.
Hepatic artery angiography was technically feasible in all animals in both groups. The time required for shaving was 55 seconds ± 9.9 in the transfemoral access group; shaving was unnecessary in the transauricular access group. The times needed to obtain intraarterial access, perform hepatic artery angiography, repair the access site, and perform the entire procedure in the transfemoral and transauricular access groups were as follows: 503.3 s ± 211.8 and 97 s ± 83.3 (P < .001), 229.6 s ± 90 and 310.7 s ± 211 (P = .705), 305.5 s ± 80.6 and 90 s ± 0 (P < .001), and 1,038 s ± 265.9 and 497.7 s ± 256.9 (P = 0.001), respectively.
Hepatic artery angiography is technically feasible via transauricular arterial access. The major advantages of transauricular arterial access versus transfemoral arterial access include a procedure time reduced by the omission of shaving and surgical cutdown.
评估经耳动脉入路的可行性，并比较兔模型中经股动脉与经耳动脉入路行肝动脉造影的所需程序时间。
本研究获得了实验动物护理和使用委员会的批准。20 只兔子分为经股动脉入路组（n = 10）和经耳动脉入路组（n = 10）。该程序包括剃毛、获得动脉内入路、进行肝动脉造影和修复入路部位。采用 Mann-Whitney U 检验比较两组的总程序时间和每个步骤所需的时间。
两组动物的肝动脉造影均技术上可行。经股动脉入路组剃毛时间为 55 秒±9.9 秒；经耳动脉入路组无需剃毛。经股动脉和经耳动脉入路组获得动脉内入路、进行肝动脉造影、修复入路部位和完成整个程序所需的时间分别为：503.3 s±211.8 和 97 s±83.3（P<0.001）、229.6 s±90 和 310.7 s±211（P=0.705）、305.5 s±80.6 和 90 s±0（P<0.001）和 1,038 s±265.9 和 497.7 s±256.9（P=0.001）。
经耳动脉入路行肝动脉造影在技术上是可行的。与经股动脉入路相比，经耳动脉入路的主要优势在于省略了剃毛和手术切开，从而缩短了程序时间。
