Question: Why is 1/2 of my muscle missing after PDA surgery

 D3AN - Thu Jan 22, 2009 5:33 am

Hi Doctors, I underwent surgery for patent ductus arteriosus as a premature baby. I'm 22 now and half of my pectoral muscle has always been missing where the incision was made. I'm just curious why 1/2 of my muscle is missing. Was it simply not sutured back together? Thanks for any help

User avatar Hello -

My best guess is that during the surgery, when the muscle was separated, due to the location of the incision and the small scale of you as a premature infant, some of the muscle tissue was simply lost outright or to wasting during the healing process. There is such a huge difference not only in scale but in development between adults and less-than-full-term babies that it would be rather surprising if this hadn't happened.

I hope this answers your question adequately. Good luck to you.

Something else to think about would be if the nerve that innervates that particular muscle was severed during surgery. That could lead to the atrophy of that muscle group.
