| 目的：探讨经颅多普勒超声（TCD）在低流量颈动脉海绵窦瘘（CCF）中的诊断意义。方法：通过TCD
对1例经DSA确诊的低流量CCF患者的血流动力学进行检测和分析，并结合文献进行回顾性分析，比较其
与高流量CCF血流动力学特征的不同，总结其特殊之处。结果：本例低流量CCF患者TCD表现为眼动脉血
流速度增高，频谱颅内化。搜索既往报道的关于 TCD 检测 CCF 血流动力学特征的病例。高流量 CCF 的
TCD主要表现为：患侧颈内动脉颅外段（瘘口近端）的血流速度明显增高，搏动指数（PI）降低，呈典型的高流
低阻表现；患侧大脑中动脉、大脑前动脉流速降低；颈内动脉虹吸段流速明显增高，频谱紊乱，声频嘈杂，同
时可出现涡流与紊流，并可探测到相对低平的波动性的静脉血流信号；眶上静脉血流反向，有搏动性且流速
增高。低流量CCF的TCD主要表现为：各血流参数无明显差异，颅底各动脉流速、PI值及频谱形态正常且
基本对称。结论：TCD对于低流量CCF具有较高的筛查和诊断价值。 |

| To assess the value of transcranial Doppler ultrasonography (TCD) in the diagnosis of
low-flow internal carotid cavernous sinus fistulae (CCF). Methods: In this paper we detected the characteristic
TCD change in a case of low-flow CCF diagnosed by the DSA and reviewed the relevant literature. The
hemodynamic features of low-flow and high-flow CCF subtypes were compared analyzed, and the differences
were summarized. Results: In the case studied, the TCD characteristic of low-flow fistula showed increased
ophthalmic artery blood flow velocity, and the frequency spectrum was intracranial. Having searched relevant
cases, we found characteristic TCD findings associated with high-flow CCF to be as follows: the typical TCD
signs of CCF are increased blood flow velocity and decreased pulsatility index (PI) of the extracranial internal
carotid artery (proximal to the fistula); blood flow velocity of the MCA and ACA is reduced; high flow velocity
is found on the siphon carotid artery as well as spectrum disorder and acoustic noise, vortex flow and turbulent
flow may simultaneously appear, and low-level fluctuating venous blood flow signals can be detected; the SOV
has reversed blood flow with arterialization and increased flow velocity. The main TCD characteristics of
low-flow CCF are as follows: there is no obvious difference between the blood flow parameters; the blood flow
velocity, PI, and frequency spectrum of the basilar artery are normal and symmetric. Conclusion: Our findings
highlight the value of TCD in decision-making during the screening and diagnosis of low-flow CCF. |
