Abstract

Background: The incidences of thromboembolism (TE) in neonates were reported to be around 0.51 per 10,000 live births per year for overall TE and 24 per 10,000 NICU admissions per year. As the incidences of TE in children and adults are lower in Asian populations, the incidences, risk factors, and outcomes of neonatal TE may be different to those reports from other countries.

Objectives: To determine the incidences, risk factors, and outcomes of neonatal TE in a tertiary care hospital in Thailand.

Materials and methods: A retrospective study between the years 1998 and 2015.

Results: From a total of 2463 neonatal admissions, 28 patients were diagnosed with TE. The female/male ratio was 1:1.2. The breakdown of diagnoses of neonatal TE were arterial ischemic stroke (AIS; 36%), arterial TE (ATE; 29%), deep vein thrombosis (DVT; 14%), cerebral venous sinus thrombosis (CVST; 11%), renal vein thrombosis (RVT; 3%), and purpura fulminans (2%). Underlying diseases were identified 57.1% of patients. The most common thrombophilic risk factor was protein C (PC) deficiency (14.3%). The overall mortality rate was 14.3%.

Conclusion: The most common TE was AIS. PC deficiency was the most prevalent inherited risk factor, especially in neonates without precipitating factors.

Keywords: Neonate; outcome; protein C deficiency; risk factors; thromboembolism.
