Noninvasive intrasac pressure measurement and the influence of type 2 and type 3 endoleaks in an animal model of abdominal aortic aneurysm.

摘要: The objective of this study was to noninvasively detect pressure changes within an excluded aneurysm sac in animal model abdominal aortic (AAA) and the influence type 2 3 endoleaks. A porcine AAA that allows for creation endoleaks used. miniaturized monitoring device (3 x 9 1.5 mm; Remon Medical Technologies, Caesarea, Israel) implanted surgically created sac. is ultrasound-based system measurements a noninvasive, transcutaneous fashion. In addition, catheter-based pressures were taken aorta directly Noninvasive fashion between initial operation time sacrifice, when endoleak (2 weeks). median mean arterial 66 mm Hg (range 55-120 Hg; N = 8). noninvasive with 48 39-90 8) almost identical measurements. could be measured as early postprocedure day 1. Two animals had follow-up suggested closure during observation period. With endoleak, catheter waveform changed from flatline trace higher-pressure pulsatile (median 54 range 46-81 8), reproducing waveform. This first study, our knowledge, demonstrates efficacy identifying technology holds great promise patients identification after EVAR may allow change current strategy.
