Intra-Sac Pressure Measurement of Abdominal Aortic Aneurysm to Reveal The Characters of All Types of Endoleak / 中国普外基础与临床杂志

ABSTRACT

0 but was obviously lower than P_ sys in no endoleak. P_ sac approached P_ sys in type Ⅰ and type Ⅳ endoleaks. Some researches showed that P_ sac in type Ⅱ endoleak was higher than that in no endoleak and even approached P_ sys , however the other researches showed that P_ sac in type Ⅱ endoleak was lower than that in no endoleak. Conclusion Postoperative P_ sac dropping greatly eliminated the risk of aneurysm rupture, which symbolized the success of endovascular therapy. Even if the type Ⅰ endoleak of small size might lead to obvious elevation of P_ sac , which necessitates management. The impairment and management tactics of type Ⅱ endoleak remained equivocal, which required further study.
