Secondary intervention following endovascular repair of abdominal aortic aneurysm: A single centre experience

Abstract

Technical failure rates were significantly higher in our earlier experience. Open repair, which was a feature of our early experience, has been avoided over the final 3 years. Instead, endoluminal techniques were used without further morbidity or mortality. Aneurysm rupture has not so far been experienced in this experience.

Surgical corrections of endovascular aneurysms: Repair complications

“…Endovascular correction or conversion is determined to be the method of choice for most EVAR complications repair 7,9,[11][12][13][14][15] . The concept of having a "tool-box" con- .…”

“…Surgical repair is thus indicated where endovascular repair is impossible or where it has failed 16 . Some reports present more frequently surgical procedures (as the technically easier option) used for complications solution early in their EVAR experience in contrast to later periods 9 . We preferred endovascular correction or conversion procedures, which, when indicated were mostly successful [23][24][25][26] .…”

“…Most elective re-interventions are due to endoleak. The majority of acute re-interventions are required due to stentgraft thrombosis with acute limb ischaemia 7,9,11,[14][15] . Our experience with EVAR complications requiring intervention is comparable with other presented reports.…”

“…The unplanned procedures are those, which deal with immediate EVAR complications. Secondary procedures are performed to solve complications during the subsequent operation as early (within the first 30 days from EVAR) or late (after 30 days) and the indication can be acute or elective 9,11,17 .…”

“…Fortunately, most EVAR specific complications related to the aneurysm and the stentgraft (such as endoleaks, stentgraft migration, kinking, stenosis or occlusion) are usually successfully solved to facilitate or preserve the stentgraft function or passage and to achieve acceptable primary technical and longterm clinical success. This complications solution involving endovascular or surgical procedures, such as corrections and conversions, is reported in 10-34 % of cases 1,[6][7][8][9][10][11][12] . Well accepted by patients and technically mostly successful endovascular procedures are the methods of choice for most solutions to EVAR complications [13][14][15] .…”
