In Reply to: Case 1199_03 -- Anatomical Variations in Uterine Artery posted by Editor on November 02, 1999 at 10:45:33:
I have seen anatomic variants in about 1% of patients overall. So far there have been 4 patterns:
Complete absence of 1 UA (UA branches replaced to the varian A) - I've seen 8 cases out of >580
Complete absence of both UAs (all flow from the ovarians) - I've seen 2 cases out of >580
Replacement of some branches of the UA to the ovarian - I've seen 2 cases out of >580
Absence of a main UA trunk with multiple UAs arising independently from the Ant Div of the IIA - This is probably the rarest. I have never seen a case personally.
There also are cases of collateral flow from the Ovarian (see my comments on case #2 this month).
This will be reported in the December issue of MITAT.
