I was a forceps delivery. I'm curious. Any others delivered with the help of forceps?
Bilateral obstruction of the internal jugular veins is rare in the neonatal period
and no long-term follow-up has been reported yet. We report two cases. The first developped an extensive thrombosis of superior veina cava related to a central veinous line, the second an unilateral thrombosis of the transverse-sigmoid sinus associated to a constitutional hypoplasia of the contralateral jugular vein. In the latter case, no cause or risk factor was noticeable, except for a forceps delivery
. In both cases the clinical course was dominated by the development of a prominent collateral network of cervico-facial veins and by a progressive macrocrania. According to MRImaging, the latter was not related to a dilation of CSF spaces, but to a macro-encephaly, either by inflation of the vascular veinous compartment inside the parenchyma or by genuine brain's overgrowth. Long-term follow-up showed a grossly normal course, both from the neurological and the scholar point of view. However, slight neuropsychological anomalies were noticed, bringing some shade on the prognosis.
