硬膜下血肿和水囊瘤是中颅窝蛛网膜囊肿较少遇到的并发症,此前可能有头部外伤史。囊内或囊壁的桥静脉和较脆弱的软脑膜血管可能是其出血原因,囊壁破裂囊液流入硬膜下腔可产生急性或慢性水囊瘤。文献报道,对该类并发症的处理需打开囊肿腔、清除占位性液体。该研究探讨了采用较保守、勿需直接行囊肿切除的依据及其效果。 作者对658例蛛网膜囊肿中并发慢性硬膜下血肿 Subdural hematoma and hydrosphere tumors are less common complications of arachnoid cysts in the middle cranial fossa, after a history of head trauma. Intracapsular or cyst wall of the vein and the more vulnerable pia mater blood vessels may be the cause of bleeding, cystic fluid into the epidural space can produce acute or chronic water cyst. Reported in the literature, the treatment of such complications need to open the cyst cavity, clear the space-occupying fluid. The study explored the use of more conservative, do not need direct cyst excision basis and its effectiveness. The authors of 658 cases of arachnoid cysts complicated by chronic subdural hematoma
