You fail to realize that Ciswoman don't have testicles as Pre-op Transwoman do.
That has no bearing on the risk of DVT whatsoever. Studies in men with testicles (with advanced cancer) treated with estradiol, with high levels, through patches, showed that the risk of DVT did not increase and actually decreased.
QuoteI think you added one too many zeros there also. I think those levels would kill someone. Looks like a typo...
No, it wasn't a typo. My estradiol levels are 1,000-4,000 pg/ml since 2014. I'm under the supervision of 4 doctors. My blood test results come back normal. I'm healthy. My blood pressure measured this morning was 120/77.
Pregnant women have levels between 1,000-40,000, sometimes up to 75,000 pg/ml. The risk of DVT during pregnancy is 0.1%, of pulmonary embolism, 0.01%.
http://www.ilexmedical.com/files/PDF/Estradiol_ARC.pdf"Normal estradiol levels are lowest at menses and into the early follicular phase (25-75 pg/mL) and then rise in the late follicular phase to a peak of 200-600 pg/mL just before the LH surge, which is normally followed immediately by ovulation. As LH peaks, estradiol begins to decrease before rising again during the luteal phase (100-300 pg/mL)."
"
If conception occurs, estradiol levels continue to rise, reaching levels of 1,000-5,000 pg/mL during the first trimester, 5,000-15,000 pg/mL during second trimester, and 10,000-40,000 pg/mL during third trimester. 6-8"

3226 +/- 393 pg/ml after 3 months and to
2552 +/- 254 pg/ml after 6 months, respectively, in group A. Bone density increased by 15.3 +/- 3.6% within the first 3 months to a total of 18.8 +/- 3.9% after 6 months, respectively. Two patients we have controlled for two years, maintained this increase. In group B estradiol increased from 27.8 +/- 6.5 pg/ml to
3028 +/- 728 after 3 and to
2491 +/- 684 pg/ml after 6 months. Bone density in this group increased by 11.8 +/- 1.9% within 3 and to a total of 18.2 +/- 2.8% after 6 months."
Authors of this study reported minimal side-effects and good tolerability.

QuoteYou can't compare Cis-Gender Woman to Pre-Op Transwoman. With testicles still producing testosterone it COULD have a different effect going off of Hormones.
Studies in cismen with testicles, as noted above, have shown that the impact on coagulation (i.e. negligible) of high levels of estradiol (mean levels 500-600 pg/ml, up to around 1,000 pg/ml) to be similar to ciswomen, when bio-identical estradiol is taken non-orally. There are studies in transwomen too that show that despite high doses of bio-identical estradiol, taken by patches or injections, there were barely any thromboembolic complications (occurrence less than 1%).
I'm addressing the issue of stopping HRT due to the risk of DVT, not the effect that stopping hormones will have on DVT. I think you misunderstood my point.
QuoteWhen a Transwoman stops all Hormones, Estradiol Levels drop and Testosterone once again takes over if Pre-Op.
What I'm saying is that it doesn't appear necessary to stop bio-identical estradiol, especially if taken non-orally, in doses typically prescribed to us, due to risk of DVT. There is no evidence supporting it. Please note that I AM NOT A DOCTOR. Consult with your doctors and share these studies with them if you wish. I'm stating my own opinion based on the data I have thus far come across. Some doctors may agree, some may disagree. As always, follow your doctor's advice.
I did not stop estrogen prior to gallbladder surgery or any of my flights.
Andrologia. 2014 Sep;46(7):791-5."it may be prudent to discontinue hormone treatment at least 2 weeks before sex reassignment surgery (SRS) or other elective surgery,
although this is not supported by evidence. After surgery the VTE risk decreases slowly over weeks (Sweetland et al., 2009), and resuming hormone treatment postoperatively after 3–4 weeks seems a reasonable approach
although, again, not supported by evidence"
