Abstract:
Objective To evaluate aneurysm sac pressure monitoring during endovascular repair (EVAR)of abdominal aortic aneurysm. Methods From April 2006 to May 2007,12 patients with abdominal aorta aneurysm underwent endovascular aneurysm repair.The average max-diameter of the aneurysm WR8(5.83±0.95)cm.The sac pressure was monitored during the whole process of the operation.The correlation between the pressure and endoleaks and long-term outcomes was observed during follow-up.Results Before the stentgraft was delivered.sac pressure was equal to the systemic blood pressure in all the 12 cases.After the EVAR wag finished,the sac systolic pressure dropped by＞40% in 11 cases,among which sac blood pressure bropped by ≥50% in 7 cases.sac pressure did not change in 1 case.In all the 12 cases,pulse pressure diminished by＞30%,and＞75%in 6 cages.During the follow-up,there were no endoleaks and death.In 5 Cases.with sac systolic pressure drop＞50%,the max-diameter of the aneurysm decreased by 1.6～3.1 mm,while in one c88e,in which sac pressure had no change the postoperative maxdiameter of the aneurysm has increased by 3.2 nma. Conclusion Abdominal aorta aneurysm sac pressure monitoring during EVAR helps to predict the change of the sac pressure after EVAR,and to detect the endoleaks.
