To report on a case that demonstrates the use and current limits of abdominal aortic pressure sensor devices.
An 83-year-old, high-risk patient underwent endovascular aortic repair (EVAR) of an infrarenal aortic aneurysm (maximum aneurysm diameter: 6.5 cm) with implantation of a pressure sensor device. At the end of the procedure and on the first postoperative day, the sensor detected persistent high pressures in the aneurysm sac, indicating an endoleak that could not be visualized on the intraoperative completion angiography but was confirmed on duplex ultrasound. During repeated angiography (postoperative day 6), again no endoleak could be detected, this time corresponding with the sensor reading that was unfortunately not interrogated again before the reintervention.
Pressure sensor devices provide a useful, additional diagnostic tool in detecting and following endoleaks after EVAR and can help guide decisions regarding reinterventions.
报告一例展示腹主动脉压力传感器装置的使用及当前局限性的病例。
一名83岁的高危患者接受了肾下腹主动脉瘤（最大动脉瘤直径：6.5厘米）的血管腔内主动脉修复术（EVAR），并植入了压力传感器装置。在手术结束时及术后第一天，传感器检测到动脉瘤腔内持续存在高压，表明存在内漏，术中完成血管造影时未发现该内漏，但经双功超声证实。在术后第6天进行重复血管造影时，再次未检测到内漏，此时传感器读数与之相符，但遗憾的是在再次干预前未再次询问该读数。
压力传感器装置为检测和追踪EVAR术后的内漏提供了一种有用的辅助诊断工具，并有助于指导有关再次干预的决策。
