双侧眼上静脉（SOV）扩大很少发生在脓毒症和无菌性海绵窦血栓形成、眼外肌扩张阻塞SOV引起的Graves病或逆行血流引起的颈动脉-海绵窦瘘患者中。作者描述了11例通过计算机断层扫描发现的双侧SOV增大伴脑肿胀的患者。随着脑肿胀和颅内压升高的消退，双侧增大的sov恢复到正常大小。据作者所知，这是首次报道双侧SOV增大与弥漫性脑肿胀相关，随后在脑水肿治疗后消退。作者认为，双侧SOV增大是由脑肿胀引起的机械海绵窦静脉停滞引起的，这是一种比目前认识到的更常见的综合征。
Bilateral superior ophthalmic vein (SOV) enlargement has rarely been shown to occur in patients with septic and aseptic cavernous sinus thrombosis, Graves' disease due to obstruction of the SOV by enlarged extraocular muscles, or carotid-cavernous fistulas caused by retrograde flow. The authors describe 11 patients with bilateral SOV enlarge ment associated with cerebral swelling as detected by computerized tomography scanning. The bilaterally enlarged SOVs returned to a normal size following resolution of cerebral swelling and elevated intracranial pressure. To the authors' knowledge, this is the first report of bilateral SOV enlargement associated with diffuse cerebral swelling that subsequently resolved after treatment of the cerebral edema. The authors believe that the bilateral SOV enlargement was caused by mechanical cavernous sinus venous stagnation due to cerebral swelling, a syndrome that occurs more commonly than currently appreciated.
