UPDATE: On Tuesday, Jaxx was walking again, with the help of his dad. Pete Denny sent News 2 a home video of Jaxx back in action.
Reidsville, NC -- After three weeks in Children's Hospital of Philadelphia, Jaxx Denny is finally home.
The Reidsville miracle baby had complications after surgery to expand the rods in his back and rib cage.
Doctors told Pete and Tammy Denny that Jaxx's August 28, 2012 surgery was a success.
However, the right side of his heart became enlarged. Doctors said it was working too hard to pump blood to his right lung and throughout his body.
Doctors diagnosed Jaxx with pulmonary hypertension, a condition that neither the Dennys nor doctors were aware Jaxx had.
After surgery, doctors had to put Jaxx on a ventilator. At one point, they told Pete and Tammy Denny that Jaxx's condition was critical.
Thanks to lots of prayers, Jaxx's condition began to improve slowly.
On Monday, he was discharged from the hospital.
Jaxx arrived home to his big brother and sister anxiously waiting for him.
"We didn't know if we would bring him home," said Jaxx's Mom, Tammy Denny.
Denny said the last three weeks have been overwhelming.
"When they tell you your kid might go into cardiac arrest, you find out real quick who you trust. We're just thanking God that he just pulled him right through and look at him! Proof is in the pudding," said Pete Denny. "God is good."
This was only the first expansion surgery for little Jaxx.
The 15-month-old was born without a kidney, without six ribs on his right side, and a spine shaped like an "S".
Back in May, doctors operated on Jaxx. They were able to rebuild his ribcage and straighten his spine using four metal rods.
Since then, he's made remarkable progress. Jaxx has been able to sit up and even stand up on his own.
About every four months, the doctors have to expand his rods to grow with him.
Jaxx has another expansion surgery scheduled for January. However, a whole team of surgeons is prepared to make sure he has no more complications.
