Any medical experts out there have a suggestion on what relatively routine surgery would be the most plausible candidate for a single knife slip to result in death to the patient?

I'm talking a serious slip--think "surgeon has a seizure" kind of thing.

This would be some procedure that brings the scalpel close to the aorta or carotid, maybe, where one very bad slip at just the wrong time could sever an artery and cause bleeding that could plausibly kill the patient on the operating table. And the more presumed "safe" the procedure the better--not talking "removing a brain tumor" or "reconstructing the aorta" kind of thing, which would already be very dangerous, high-mortality affairs. Rather, a 50 year old man goes in for a routine, non-emergency surgery and never makes it out.
