Tracheal stenosis treatment(Nightmare Problem without any diagnosis or cure) Female age 30
My wife 30 years old was diagnosed with tracheal stenosis two years ago. She had balloon dilation couple of times, and later doctor used laser to cut off the growth. Biopsy showed this as a scar tissue
We had relief for some time as my wife can breath again but after couple of weeks she again started to have tracheal stenosis. The tissue is growing again, then the doctors kept a stent in her trachea for a month. Tissue went back again and she has good clearance for breathing. After almost 9 months after stent treatment we went for checkup last week and the tissue is already starting to block my wife airway with only 40 to 50% airway clearance(first image from last week doctor visit, second image was the one from the very first finding)
Did anyone here has experience with this problem? or did anyone you know worked on this problem
Please advise any doctors or hospital. We live in India, and we also have residence in Germany.
Your suggestions and guidance is very helpful to us, our lives are totally impacted due to this problem and my wife is totally depressed and no doctor is able to help us. We almost exhausted our savings and sold properties to find a treatment for us but so far no hope. Please help with any information you are aware of
