上矢状窦血栓形成较少见,文献报道多为散发病例,儿童较成人多见。有人报告一组尸解1396例中有21例,或称每2500妊娠中有1例。本病主要表现有急性或亚急性颅内压增高,癫癇发作,肢体瘫痪及精神症状等。病因和发病机制上矢状窦血栓形成的病因与发病机制主要有以下几个方面。一、炎症性上矢状窦血栓形成: 由于副鼻窦、大脑半球内侧面均有小静脉与上矢状窦相通,乙状窦、海绵窦也可经窦汇或侧裂静脉到达上矢状窦,因而上述部位的炎 Upper sagittal sinus thrombosis is rare, reported in the literature mostly sporadic cases, more common in children than adults. It was reported in 21 of 1396 cases of an autopsy, or 1 in every 2500 pregnancies. The main performance of the disease with acute or subacute increased intracranial pressure, seizures, limb paralysis and mental symptoms. Etiology and pathogenesis of caecal sinus thrombosis etiology and pathogenesis mainly in the following areas. First, the inflammatory upper sagittal sinus thrombosis: Since the paranasal sinuses, the medial hemisphere has a small veins connected to the superior sagittal sinus, sigmoid sinus, cavernous sinus can also be sinus or lateral fissure vein to reach the superior sagittal sinus , So the above site inflammation
