A. Open repair is indicated in young patients as an elective procedure, or in growing or large, symptomatic or ruptured aneurysms. It was the main surgical intervention used from the 1950s until other procedures developed.
For most operations, the surgeon tries to use as small an incision as reasonably possible, but that is not the case for open AAA surgery because there is an overriding concern. The aorta must be clamped off during the repair, and that denies blood to the entire abdomen and both legs; this can cause a whole range of complications
Recovery after open AAA surgery takes significant time. The minimums are a few days in intensive care, a week total time in hospital and a few months before full recovery.
Endovascular repair first became practical in the 1990s and although it is now an established alternative to open repair, its role is yet to be clearly defined. It is generally indicated in older, high-risk patients or patients unfit for open repair
