But what I'm referring to here with Dr. Paduch, however, is what he's calling a more exact and precise method to treat venous leak with ligation surgery. Ligation surgery has a checkered past of providing some sort of improvement for the first 6 months or so, but then reverting to pre-surgery levels of venous leak within a year. Dr. Paduch claims that his 3D Dynamic MRA is able to pinpoint which veins specifically should be ligated, leading to a higher success rate that sustains for longer (but it seems like there isn't much data yet to substantiate this claim).
Anyway, I thought it was interesting that the 3D Dynamic MRA is able to more precisely pinpoint vascular irregularities and figured I'd see if anyone else has thoughts on this.
Hi Passerarf, I have given venous leakage a great deal of thought, and found a number of interesting studies that shed a new light on why it happens.
Read my post here to save repeating it all.
viewtopic.php?f=3&t=14596#p128888I feel the surgeon would have to remove the offending veins that are either directly under the tunica albuginea or the faulty emissary veins that pass through the tunica for this approach to be really viable. These are the veins that get compressed, which severely limits outflow. The more compression of these veins by the corpus cavernosum the better the restriction. This all depends on two things:
The ability of smooth muscle in the corpus cavernosum to work effectively and its quantity, plus the structural integrity of the trabeculae.
The ability of the tunica albuginea to perform its function of creating a seal.
What happens with the veins after that point is IMO not going to fix the issue for long. Yes, it may help to lessen the “rate” of outflow, but there will still be “a leak” as there must still be a route for the blood to escape via some of these veins. Therefore if the leak is still at the critical areas as I mentioned above the blood will still escape.
As the issue with the smooth muscle or the tunica albuginea worsens and research shows it does, as each decade of life passes, the leak will continue to worsen, and the mitigated effect of the surgery will wane. This is most likely why vein ligation is not very successful or does not work for long.
As your condition looks to be congenital, (as we have spoken about this before privately) you may have some abnormal “venous shunts” that leave the corpus cavernosum feeding directly into the veins just on the outside of the tunica albuginea (TT). Essentially these could be deformed emissary veins that allow too much blood to pass through the TT. If the doctor you have mentioned, has a method by which he can very accurately find such veins and remove them, there then IMO could be a chance that such surgery could be successful. The ligation surgery I have seen in studies, does not seem to be anywhere near this accurate. If your issue is to do with a faulty congenital mechanism of the corpus cavernosum to be able to expand sufficiently, such as some form of hypertonic cavernous smooth muscle as we have discussed in detail privately, I think the surgery would not help a great deal.
It will be very interesting to see how you respond to the phentolamine mesylate tablets.
