I apologize to comment on this discussion rather late...the aium e-community is wide!!.
Yes, Prof Gilani is very right: It is an established finding both from the researches published, and from my personal experience that that high resistance utero-placental flow (uterine artery) and high resistance feto-placental flow (umbilical artery) are associated with IUGR and poor outcome. The suboptimal flows are associated with pregnancy-induced hypertension (PIH), a background of PCOS, antiphospholipid syndrome syndrome and hypercoagualability conditions.
Recently a lady with severe PIH not only had diastolic notching of the umbilical artery, but REVERSED diastolic flow with marked IUGR and sub-optimal fetal biophysical profile.
I have a collection of archives on the doppler observations; interested colleagues may email me at firstname.lastname@example.org for sharing.
Talking of the umbilical cord, could someone please comment on the observation attached herewith. The obstetric details are self explanatory on the image. It appears to be a short, thick, ?semi-torsed umbilicus with whirlpool pattern in short axis, and exaggerated Wharton jelly The fetus was otherwise normal with congruent dates-biometry, and optimal biophysicals. The flow profile is unremarkable.
dear friends this topic by dr ibrahim is not getting attension--it is very important--for irreversible IUGR etc,please send details.
