Neonatal arterial thrombosis: an arcane COVID sequelae.

We describe a case of a term neonate with a swollen right arm and weakened pulses, diagnosed with arterial thromboembolism in the right axillary and brachial arteries. Treatment involved heparin, followed by enoxaparin, resulting in significant improvement. Maternal SARS-CoV-2 infection during pregnancy was considered as a potential factor, supported by the newborn's reactive COVID antibodies. The authors hypothesise a potential correlation between neonatal thrombosis and maternal SARS-CoV-2 infection during pregnancy. It is important to note that this association remains speculative and warrants further investigation for validation. The case underscores the importance of recognising and managing neonatal arterial thrombosis, especially in the context of maternal illness. We discuss the case in detail and review current knowledge on this condition.
