The Rex Shunt Procedure for Portal Hypertension

The Rex Shunt procedure is a relatively new treatment procedure for portal hypertension that has been performed on children with positive results.  According to what I have learned, there are now over 90+ children in North America who have had the operation.

The Rex Shunt procedure has primarily been performed at Children’s Memorial Hospital in Chicago, Illinois by Dr. Riccardo Superina.   (There maybe a few other places in the world where this procedure is being performed, but I was unable to glean that information at this time).  If you are aware of any other locations please feel free to post your comments below.

Dr. Superina explains the procedure in the video below …

What is the Rex Shunt Procedure?

On the Facebook blog I subscribe to,  a fellow member had asked Dr. Superina directly whether or not the procedure could be performed on adults, and this was his reply …

“There is no reason that it cannot be applied to adults, and we would be happy …to hear their cases if they wished to send case summaries along and recommend further investigation or action.”

If you wish to send a case summary to Dr. Superina his mailing address is:

Riccardo Superina, MD

2300 Children’s Plaza, Box 57

Chicago, IL 60614-3363

Considering my particular case, the verdict is still out as to whether doctors would even consider a procedure such as this, or for that matter any kind of operation due to my underlying clotting condition?   For you though, or possibly someone you know maybe this procedure is something worth pursuing?

I had the privilege yesterday of meeting (via the web) Shelly Hart whose daughter Aubree had the Rex Shunt procedure performed by Dr. Superina 2 1/2 years ago.  Shelly has granted me permission to post her blog and you may view it by clicking here: Please click on Aubree’s health updates to view her personal journey!  Thank you Shelly!

If you have a story to share regarding the Rex Shunt procedure or for that matter any other procedure your post is most welcome here!

Hi Clint

I discover your website now! Sorry for not having contributed earlier as your topic is one of my preferred one… I ll try to do better if I can in the future.

I found you had some difficulties in finding precise informations about a few facts, and for example MesoRex bypass in adults.

I like to confirm what has been suggested by some other: yes a mesoRex is feasible in adults…but with many more limitations compared to that in children (mostly depending on the cause of portal vein thrombosis in fact).

The first Mesorex procedure ever was performed in April 1990 in a child in Belgium, and the first Memorex in adult was done in 1995, also in Belgium. You can find references to these in medical journals as follow:

Since then, the procedure expanded very much within the pediatric age, But it has been not much used for adults for reasons I don’t want to expand now and here. Few cases I know having been done … are not reported in literature (for various reasons including that the case reports that were proposed were rejected by a series of “adult” journals, considering it is not relevant… including recently WJS).

There are many aspects that are very interesting to discuss about the MesoRex, or about what should be preferred if a Memorex can’t be done. Please keep your website going on, as this seems a place where really a good discussion can take place and helping people. I will come back later for discussing other if you think it is appropriate. Thank for your work.

good evening

Thank you so much for this valuable information! I hope this will answer more questions for people and ultimately give them hope that there is some options available.

Dear Amanda,

In order to know if your daughter is a good candidate for a Memorex bypass, try to answer the following questions.
This is a very “practical” approach and even if you don’t find how to answer, or if you do not have the right answers, please ask for complementary advice.
But if you can answer straight to the 4 questions, you may have a first idea about what are the possibilities.

1 – was your daughter born a term and rapidly went at home (A) or was she premature, or in distress, or other and transferred to a neonatal care where she was treated with positioning a catheter venous catheter in the umbilical vein (B)?
2- did she had a CT scan with angio performed showing that the superior mesenteric vein is patent and normal anatomically speaking (A) or if it is not completely normal (B)
3- did she had a US Doppler of the neck showing that both internal jugular vein are patent and similar in diameter (A) or are different in diameter (one is >35 % different or is thrombosed) (B)
4- did she undergo a retrograde venous portography (see showing the Rex is patent (independently of the diameter) or did she not, or is the Rex thrombosed (B)

Anybody getting 4 “A” is an optimal candidate for a Mesorex bypass, which would allow him to get back to a normal condition if performed early in life (> 95% in expert hands) or close to normal if performed at a later age.
Anybody getting one “B” could be a candidate but needs a special opinion
Anybody getting 2 “B” should be assessed and proposed surgery with care

Hope this helps

Again…this is valuable information. Thank you so much for taking the time to answer Amanda in such a precise way. Please feel free to post again! Clint
