Clinical Significance and Treatment Strategies of Patent Ductus Arteriosus in Preterm Infants: An Evidence-Based Approach to Decision-Making

Soon Min Lee, Byong Sop Lee, Mi Young Han, Hyun Ho Kim, Teahyen Cha, et al.

Neonatal Med. 2026;33(1):4-17.

The pathophysiology of patent ductus arteriosus (PDA) is conventionally attributed to increased pulmonary blood flow and reduced systemic organ perfusion caused by left-to-right ductal shunting. Although PDA has been associated...

미숙아 동맥관개존증의 임상적 의미와 치료 전략: 대한신생아학회 권고문

이순민 , 이병섭 , 한미영 , 김현호 , 차태현 , et al.

Neonatal Med. 2026;33(1):18-29.

The pathophysiology of patent ductus arteriosus (PDA) is conventionally attributed to increased pulmonary blood flow and reduced systemic organ perfusion caused by left-to-right ductal shunting. Although PDA has been associated with major complications of prematurity and neurodevelopmental impairment, establishing direct causality remains challenging due to multiple confounders, including interactions among...

Real-World Outcomes of Treprostinil Treatment in Very-Low-Birth-Weight Infants with Pulmonary Hypertension: A Nationwide Cohort Study

Jieun Jeong, Haemin Kang, Ho Jung Choi, Sohee Oh, Jin A Lee

Neonatal Med. 2026;33(1):56-65.

Purpose: Treprostinil is used off-label for refractory pulmonary hypertension (PH) in very-low-birth-weight infants (VLBWI); however, real-world outcome data remain scarce. This study aimed to describe the clinical and long-term neurodevelopmental outcomes of treprostinil-treated VLBWI with PH. Methods: Data from 21,645 VLBWI in a nationwide, multicenter registry (Korean National Network) admitted between...

Language Outcomes in Moderate-to-Late Preterm Infants at 2 Years of Corrected Age

Sung Hee Lee, Ju Hyun Jin, Shin Won Yoon

Neonatal Med. 2026;33(1):66-73.

Purpose: Moderate-to-late preterm (MLPT) infants born at 32 to 35 weeks of gestation are often considered to be at low risk for developmental delays. However, emerging evidence suggests vulnerabilities in language development. This study aimed to evaluate language outcomes in MLPT infants at a corrected age of approximately 2 years. Methods:...

Hye Jin Park, Sang-Yoon Lee, Hyeong-Taek Woo, Ji Sook Kim

Neonatal Med. 2026;33(1):93-104.

Purpose: Posthemorrhagic ventricular dilatation (PHVD) is a significant complication of intraventricular hemorrhage (IVH) in neonates. This study aimed to evaluate the clinical characteristics, treatment course, and neurodevelopmental outcomes of neonates with PHVD after grades II–IV IVH. Methods: This retrospective single-center cohort study included neonates with grades II–IV IVH admitted between January...

Infants with Sacral Dimples: Clinical Outcomes and Usefulness of Ultrasonography

Sung Hee Lee, Ju Hyun Jin, Shin Won Yoon

Neonatal Med. 2026;33(1):105-111.

Purpose: Sacral dimples are common and occur in 1.8% to 7.2% of neonates. Most simple dimples are benign, and concerns have been raised about the routine use of spinal ultrasonography for all such cases. This study aimed to analyze the spinal ultrasound findings in neonates with sacral dimples and evaluate...
