If failure to repair a cut artery is a concern with endoscopic AN removal, then how come endoscopic versions of the following surgeries are mainstream:
1) other brain tumors, like pituitary, for ex.
2) abdominal surgeries, like appendectomy, gall bladder removal, hysterectomy, exploratory surgery, etc
3) heart surgery ( no cutting through the ribs, shorter surgery and recovery times)
4) AN surgeries around the world
They must also be concerned with the same thing.
When I was researching endoscopic surgery for my AN regrowth in 2007, I realized that this argument has no value and the issue of nicking a blood vessel is present in ALL endoscopic surgeries and, therefore, has been dealt with already. Just like any surgery, endoscopy can be done poorly, carelessly and simply not work out. It has to do more with the surgeon and his technique and attitude than the method itself.
