INTRODUCTION
This case series describes a point of care ultrasound (POCUS) artifact involving the abdominal aorta of four standardized patients. The purpose of this case series is to highlight this artifact and maneuvers to discern pathology from normal.
METHODS
Permission was obtained for each case described in this series. POCUS images of the abdominal aorta in both sagittal and transverse were obtained in these four cases. The findings were reviewed and compared.
DISCUSSION
All four standardized patients were otherwise healthy, thin and female. The artifact was consistently a linear, hyperechoic structure within the lumen of the abdominal aorta in the sagittal plane.
CONCLUSION
In each of these cases, the artifact disappeared on rotation of the probe from the sagittal plane to the transverse plane. Knowledge of this POCUS artifact and maneuvers to avoid it are important in both clinical and educational settings.
引言
本病例系列描述了四名标准化患者腹主动脉出现的床旁超声（POCUS）伪像。本病例系列的目的是突出这种伪像以及辨别病理情况与正常情况的操作方法。
方法
本系列中描述的每个病例均已获得许可。在这四个病例中获取了腹主动脉矢状面和横断面的POCUS图像。对检查结果进行了回顾和比较。
讨论
所有四名标准化患者均身体健康、体型消瘦且为女性。该伪像在矢状面始终表现为腹主动脉管腔内的线性高回声结构。
结论
在这些病例中，当探头从矢状面旋转到横断面时，伪像均消失。了解这种POCUS伪像及其避免方法在临床和教学环境中均很重要。
