Honestly, though, when you're doing it "live"—which was my case since I didn't really feel the local anesthesia kick in properly—it hurts like hell, especially since there's so much muscle in that area, and then they have to slide the catheter through the vein... while it was traveling up toward my heart and wiggling around in there, it didn't exactly hurt, but man, it felt super weird.
Speaking from the perspective of someone who’s actually been through a coronary angiogram, you pretty much nailed the experience...
Just a few quick thoughts:
- These interventions are done percutaneously. Basically, they puncture the blood vessel and thread a guidewire through it, followed by a dilator, then the sheath, and then everything else goes through there. Usually, there's no scalpel cutting involved unless they need to slightly widen the puncture site to make it easier for the dilator or sheath to slide in.
- That vessel isn't a vein; it's an artery, which they use to go "upstream" through the aorta to reach the openings of the coronary arteries.
- You couldn't feel the wire passing through the aorta. Like you said, it was probably just that unsettling sensation of knowing something is crawling around inside your body...
- The local anesthesia probably wasn't applied well enough or in quite a high enough dose.
As for general anesthesia, that's really not standard practice for PTCA procedures.
