Spontaneous resolution of a fetal dural sinus thrombosis: one case report and review of the literatures

Jinsong Gao et al. Int J Fertil Steril. 2012 Jan.

Abstract

Fetal dural sinus thrombosis is a rare finding. Most cases have been terminated without long-term follow-ups. Recently some reports have indicated the potentially favorable evolution of fetal dural sinus thrombosis. Most of the fetuses showing symptoms have been delivered with normal neurologic outcome. We report a case of fetal dural sinus thrombosis. Serial ultrasound and magnetic resonance images (MRI) showed the shrinkage of the thrombosis which indicated good prognosis. No physical or neurological abnormality was observed at 8-months follow-up. Conservative treatment is appropriate to prenatally diagnosed dural sinus thrombosis with favorable prognostic factors. Serial MRI or ultrasound should be taken every 1-2 months to monitor the thrombosis development and fetal well-beings.
