# Preductal Hemodynamic Redistribution in Preterm Infants with Patent Ductus Arteriosus

## TL;DR

This paper examines how an open blood vessel in preterm infants affects blood flow to the upper body.

## Contribution

It presents case reports highlighting abnormal blood flow patterns in preterm infants with patent ductus arteriosus.

## Key findings

- Three patients showed abnormal Doppler flow patterns in the brachiocephalic artery.
- The study emphasizes the need for further research on preductal hemodynamics in preterm infants with PDA.

## Abstract

A patent ductus arteriosus is a common entity in preterm infants. Literature is lacking regarding physiological effects on preductal circulation. This report describes 3 patients with abnormal flow Doppler pattern in brachiocephalic artery. Further research is warranted to better understand the impact of PDA on preductal circulation.
