Another milestone, another gracious day given - surgical guarded success

I am seated by Bryce’s side, now late at night.  Myself, alone.  My beautiful bride is back in our taxing room with River and two other of our kids.  I hope she sleeps.  I doubt it frankly.  

To be honest, she, and myself less, suffered more from this last take-from-home surprise than all the previous jolts in our journey.  We left so full, free, high even from our early release …. From the truly remarkable strength of our little men.  These little fighters who must know they are already so loved, so wanted, so doted over, that they must know each of their community and familial loves first hand.  They will fight through to see us all through it seems.  For every response to a terrible situation has been astounding. Yes, abnormal even.  Take the latest with our Bryce.  We came up following a BP cuff read and confirming echo which read the difference in blood pressure from his arm to his leg at 50 points.  His leg pulse was almost indiscernible.  So he was transferred under medical protection.  When we arrived, I led the EMS through the streets of Cincy and the process of entry in the emergency wing and we were direct admitted to the room beside the one he inhabited after his birth.  That night, the difference read the same.  Things were dicey. How long could his body tolerate such paltry blood supply to the lower portion before his kidneys started shutting down and his legs changing color?  Then the next day, things seemed to level out.  The difference as read by cuff declined to 25, which shoved our case from operate now to operate very soon.  So stable was our boy, so normal his GI functions that we were transferred Saturday to the floor, out of the CICU.  Here in this spacious room on level six of the A building, his brother can actually sleep at the foot of his crib with him and our kids have unlimited access to their brother.  That makes it infinitely easier on us. 

We had our meetings today, though not with Dr. Morales, the chief of cardiovascular surgery who will perform the operation.  In our consult with Dr. Cnota, from team of cardiologists, we learned a good bit more.  He claims that in Dr. Michelfelder’s 22+ years of experience in pediatric and fetal cardiology, he had never seen a coarchtation occur in a TTTS twin.  They have had a few valve anomalies such as Bryce’s dysplastic tricuspid that manifest unresolved after the TTTS laser correction, but never a case connecting to coarchtation.  Furthermore, it is very rare for a coarchation to occur in two different places around the aortic arch.  Nonetheless, it appears that the narrowing in his aortic arch has caused pressure to increase in his lungs because the left ventricle is overworking to service the impeded lower organs thus increasing pressure at or above the heart to hypertensic levels.  This increase in pressure has applied heightened pressure once again against the left ventricle (which pumps blood to the lungs) causing the level or tricuspid regurgitation to increase to levels measured just after delivery when resistance in the lungs was greatest.  This is not alarming, and should most likely resolve after the coarchation is removed, but the tricuspid continues to leak vigorously either way.  So now, fast forward to the day of surgery.

Dr. Morales paid us a visit around 8 am to discuss his approach.  Evidently, the team meeting yesterday had many attending and was a rather lively debate with many attending cardiologists as well as the surgeons.  The meeting adjourned and the plan was to open his chest, put Bryce on by-pass, and perform the arch advancement with possible elective tackling of the dysplastic tricuspid repair.  However, Dr. Morales spent the evening weighing all the input he had received and simply came to tell us that he was going in, putting Bryce on by-pass and was going to fix what needed to be fixed the best way to fix it.  He had not set agenda on how to pull that off.  Furthermore, he had already determined NOT to address the tricuspid issue, primarily for two reasons.  One, if he attempts a repair, he circumvents the bodies opportunity to possibly resolve the issue over time, on its own.  A natural repair is always a preferred repair.  And thought the leak is not likely to ever stop short of intervention, it is possible it could slow to the point that medication could sufficiently treat it.  The other has to do with the physiology of the valve material at this early age.  Evidently, reshaping a valve this early is far less likely to produce the desired outcome because of how supple the material is.  However, over the next 6 months or so, the flesh in the valve alters and evolves and success in a repair effort becomes much more probable.  So, he thought the risks of going back in were much less than the potential loss of either preventing natural repair or insuring a greater chance of success in the repair at a later date, as in, between his 8th and 12th month of life.  He was going to look at the valve with an internal echo, but felt somewhat convicted to heed the counsel of the cardiologists and resist the temptation to intervene so early. 

Fast-forward once again to post-op consult at 5 pm.   Bryce was taken from my arms outside the OR at 9 AM, so this was an all day affair.  Morales said the procedure was very complicated.  It was, in his words, difficult to perform for several reasons.  One, the coarchtation was limited to one place, however, there had been substantial thickening in the wall of the aortic arch over a large segment, essentially the entire arch.  Because of this, it made not sense to perform the arch advancement where the descending portion is attached frontally just above the heart and the descending line is cut off and sewn into a basket.  This because there would still be the problem of the thickened wall and narrowed passage to the ascending arteries, but also because his descending line was not plastic enough to relocate to that extent.  So, he had to filet a long section of the arch and graft a patch over this portion composed of Bryce’s own pericardium that roughly doubled the size of the aorta in this area.  The flesh of the artery will grow over the patch in time.  The other complicating factor was the placement of the laryngeal nerve, which had essentially braided itself, abnormally, around the aorta.  This nerve had to be moved to complete the reconstruction of the arch.  In doing so, it had to be stretched.  That stretch may have damaged the nerve with possible side effects of poor utilization of the vocal cords for noise making and difficulty swallowing liquid without choking.  He seemed genuinely concerned about these possible side effects from the procedure but was not certain it would occur.  Furthermore, it is something that can resolve in 2 to 3 months so long as the nerve was not inalterably damaged. 

Finally, the team here is somewhat confounded by this case.  They have no idea what would have caused the second coarchtation, again in an atypical location and disassociated from the ductus.  They also have no idea what would have caused the aortic line to thicken as it had.  Because of the nature of the repair, we are very unlikely to have issues again with any of the troubled area which was repaired, however, it remains a concern to Nicole and I that if this anomalous narrowing and thickening could have occurred as it had, in various places as it did, that it might happen again with another portion of the aorta or another artery elsewhere in the body.  Because it was apparent that there was problematic tissue in this specific area, they believe there is greater likelihood it is an isolated incident.  But we will not know till time has proven so. 

Our petition for our youngest son is as follows: 
1)   That there would be no damage to the nerve and consequent complications associated with it.
2)   That this would in fact proof to be an isolated incident attributable in part to defective tissue.
3)   That extensive inflation would not occur where sutures were made or new flesh was attached because Bryce does not seem to tolerate foreign intervention in his vessels well.
4)   That the tricuspid leak would wane to the point where it is medically manageable and a reconstructive surgery will not be required, at least until well into adulthood. 
5)   Finally, that his recovery would clip along at an acceptable rate, that he will take to eating once again, breathing normally on his own, and that we might be discharged within 7-10 days. 


Please forgive me at this point for drawing to a close at the end of a rather dry presentation of medical data.  I haven’t the mental or emotional reserves to offer any personal reflection.  I cannot say we are dramatically relieved.  We are not high fiving.  We do not feel in the clear.  We have never really been in the clear and every time we think the end of the tunnel might be approaching, the light turns out to be a train.  So we walk in faith, one step, one day at a time.  Doing what we can to make the most of our days, the most of our relationships, the most of our struggle even, and doggedly clinging to a complete trust in a plan we cannot know.  Too much celebration would be ill-advised.  Too much foreboding would amount to self-pity.  So we pleasantly trust our way through the unknown.  And THANK YOU each and every one of you that has said a prayer, spared a compassionate word or thought, given support, and cared about our family.  We are deeply grateful.
