Why is it a high failure rate for tubal ligations performed during a c section?

Excellent ?: Because the tubes are more vascular and even though most docs cut tie and burn them they have more a chance ( even though they shoudn't to recannulate), so in my patients even though I have never had a tubal failure at the time of csection, I have them come back after their 6 week post aprtum check up and they can have a 5 minute office tubal by adiana or essure which is easy to do.
