| Abstract: |
Dural sinus malformations (DSMs) are rare congenital vascular diseases characterized by a giant venous pouch with or without arteriovenous shunts. We present a neonatal case of DSM that was diagnosed prenatally and treated via endovascular intervention in the early postnatal period. The patient presented with a large DSM involving the torcular Herophilion prenatal magnetic resonance imaging (MRI). Enlargement of the head circumference and respiratory failure rapidly progressed after birth. On the 5th day after birth, the neonate underwent endovascular occlusion via the umbilical artery. The arteriovenous shunt was occluded, and the reflux from the enlarged venous pouch to the dural sinus was decreased. No additional procedure other than ventriculoperitoneal shunting was required. The neonate's development slowly caught up to normal parameters. Follow-up MRI demonstrated the successful development of the venous drainage system. DSMs are characterized by an abnormally dilated dural sinus, which can block the venous return and ultimately increase intracranial pressure and cerebral ischemia. Long-term follow-up indicates that an abnormally developed dural sinus can be reconstructed by appropriate and timely treatment. [ABSTRACT FROM AUTHOR] |
