"I’ve heard of people requiring open repair after EVAR complications was this your case also"

Yes. First Evar led to numb foot and unable to walk.
Second Evar was done 1 month later. Staphylococcus bacteria that remained for many months, even 5 different antibiotics was prescribed by 2 different hospitals.

2 months later full open AAA surgery.
Staphylococcus bacteria remained even after this.
Until 4th surgery 5 months later, at another top end private hospital, one of the best in the country.

I can understand your doctor suggest Evar because less intrusive, fewer complications, much shorter recovery time, cheaper for insurance or you.

Whatever procedure the patient/doctor agree to, the risk of complications will always be there.
Before first surgery I researched to find best hospital and surgeon in my part of the country. Still, I endured many complications.

My complications become more severe after AAA surgery:
● Blood clot.
● Erectile dysfunction (temporary)
● Ejaculation impossible (reach orgasm without any ejaculation) until this day.
● Still partly numb foot, (that required a fifth surgery of a different kind).

The blood clot pain was insane, compared to any other pain one experienced before. I knew right away what it was, and ambulance was called. Emergency surgery saved my life.

Today I still suffer pain, sometimes so severe that I'm sure I will go to hospital same day, and numb foot some days.
Still prescribed strong opioids that I wish to avoid.
My hospital bag are always by the entrance door.

When in doubt, go to another hospital for second opinion.

In my case I still wish I had chosen AAA first time, and saved myself for the 2 previous surgeries. But before any surgery, I wanted smaller scars and shorter recovery time.

From surgery #4, I find it difficult to fully recover, also mentally.
3 previous surgeries, I worked hard to regain balance, learn to walk again, eat all I could to gain weight again.
Since surgery #4 I am mentally and physically totally drained, and find recovery impossible. Limit the number of surgeries needed, when possible.

Whatever surgery one choose, this will change your life, more than you can imagine.
I sincerely hope you will be luckier than me.
