Endoleaks after endovascular aortic aneurysm repair: Definition and treatment [Endovasküler aortik anevrizma tamiri sonrasi görülen kaçaklar (endoleak): Tanim ve tedavi]

Endoleak is a common phenomenon after endovascular aneurysm repair for abdominal or descending thoracic aortic aneurysms. Some types of endoleaks are totally innocuous that they have the potential of spontaneous recovery and therefore do not require intervention. However, some endoleaks might cause aortic rupture. Type 1 and type 3 endoleaks are technical failures of endovascular treatment that should be treated immediately first by endovascular means. Type 2, 4 and 5 endoleaks can be monitored for aneurysm growth with appropriate imaging techniques. Five different type of previously defined endoleaks will be reviewed and their appropriate treatment methodologies will be discussed in this manuscript.
