Embolotherapy of Persistent Endoleaks after Endovascular Repair of Abdominal Aortic Aneurysm with the Ancure-Endovascular Technologies Endograft System☆

摘要: Purpose Endoleak is a potential complication after endovascular repair of abdominal aortic aneurysm (AAA). It may result in continued growth the and potentially rupture. The authors present their experience with embolotherapy patients persistent perigraft flow treated Ancure-Endovascular Technologies endograft system. Materials Methods Between February 1996 August 1998, 54 underwent successful AAA use Ancure All operative angiography discharge computed tomography (CT). Follow-up included CT at 6, 12, 24 months, was also performed 3 months if an endoleak on CT. Persistent defined as still 6-month Seven 21 initial endoleaks persisted 6 months. Six returned for embolization space outflow vessels including lumbar arteries inferior mesenteric artery (IMA). Results Five six had leaks from proximal ( n = 1) or distal attachment sites 4) system into and/or IMA; one leak caused by retrograde IMA flow. nine procedures only minor complication. showed complete resolution decrease size sac all patients. Conclusions Although commonly seen initially system, occurred 13% study. most arises graft site combined patent such arteries. can be effectively safely embolized combination coil vessels. Such intervention resulted sac.
