Duplex scanning as an alternative to computer tomography with contrast enhancement for the control of complications after endovascular aneurysm repair

Abstract

EVAR (endovascular aneurism repair) is the preferred method for the surgical treatment of ananeurysm. The advantage of this type of surgical intervention is that a smaller number of postoperative complications will occur. The main diagnostic tasks for patients after EVAR are to determine the size of the aneurysmal sac, detection of an endoleak, detection of the endoprosthesis migration and the deformation of the stent graft itself. Conclusion: early detection of complications in the postoperative period remains the main problem for monitoring patients after EVAR. Duplex scanning is a safe, non-invasive and effective method of measuring the size of an aneurysmal sac and detecting possible complications after EVAR.
