Endovascular transvenous embolization combined with direct punction of the sinus pericranii. A case report.

Abstract : Sinus Pericranii is a rare venous anomaly in which the communication between the intra- and extracranial venous system is constituted by a network of thin-walled veins that form a varix on the external table of the skull. This varix is continuous with the pericranial veins of the scalp. We describe a 31-year-old woman with frontal sinus pericranii treated using an original endovascular technique by transvenous approach combined with direct punction.
