RESULTS: The IJVV was present in all cadavers just before its termination (60 IJVVs from 30 subjects). The valve was bicuspid in most cases (93%). The competence of 41 IJVVs was checked of which only three (7%) were found to be incompetent. All IJVVs in live subjects were found to be competent.
Valsalva maneuver. Valvular insufficiency was diagnosed when there was reflux for >0.8 seconds during the Valsalva maneuver.
Cece wrote:I agree, Fernando, what's being called valve insufficiency is the other type, where it's weak and allows backflow from the heart, not the CCSVI type, where it's fixed as an outflow obstruction.
But the cadavers aren't doing Valsalva
Can't do much without full articles, I'll see what I can do about getting them....
