Can PDA cause NEC?
The evidence behind a congenital persistent patent ductus arteriosis (PDA) as a cause for NEC is well established and has been confirmed by several prospective studies [101–103]. The left-to-right shunt that occurs in PDA results in the decreased velocity of mesenteric blood flow [104].

How does PDA cause IVH?
The association of IVH with PDA is unique and complex. Presence of a PDA has been implicated in the occurrence of IVH due to fluctuation in cerebral blood flow.
What are signs of NEC in babies?

- a swollen, red, or tender belly.
- trouble feeding.
- food staying in the stomach longer than expected.

What causes NEC in premature babies?

Can babies survive NEC?
Most babies who develop NEC recover fully and do not have further feeding problems. In some cases, the intestine is scarred, narrowed, or blocked. If so, more surgery might be needed. Malabsorption (when the intestine can’t absorb nutrients normally) can be a lasting problem from NEC.
