摘要

目的涡状静脉吻合术被广泛认为可以补偿蝶窦频谱疾病的涡状静脉充血。然而,确定代偿引流路径内的血流方向往往具有挑战性。设计回顾性观察病例系列研究对象连续689例未经治疗的中心性浆液性脉络膜视网膜病变、脉络膜新生血管病或息肉状脉络膜血管病患者。主要结果测量在颞侧涡状静脉逆行搏动性涡状静脉血流的眼球中,确定颞上涡状静脉和颞下涡状静脉之间的静脉吻合情况以及颞侧涡状静脉扩张的主要部位。结果利用早期 ICGA 视频确定了 22 只颞侧涡状静脉逆行搏动性涡状静脉血流的眼球。其中 9 只眼睛的颞上涡静脉检测到逆行搏动性血流,该静脉通过涡间静脉吻合口与颞下涡静脉相连。在这些病例中,7 只眼睛(77.8%)的对侧颞下涡静脉扩张为主,另外 2 只眼睛(22.2%)的颞上涡静脉和颞下涡静脉对称扩张。另一方面,有 13 只眼睛在颞下涡状静脉中检测到逆行搏动性血流,而颞下涡状静脉通过涡间静脉吻合口与颞上涡状静脉相连。在这些眼球中,10 只眼球(76.9%)的对侧颞上涡静脉扩张为主。结论 在睫状体频谱疾病中,有些病例充血的静脉血可能会通过蝶间静脉吻合口排入对侧蝶静脉。因此,超负荷的对侧涡状静脉可能会比原发性充血涡状静脉更加扩张。因此,不对称涡状静脉扩张的反转可能会在蝶窦频谱疾病中发生。

Inversion of Asymmetric Vortex Vein Dilatation in Pachychoroid Spectrum Diseases

Purpose

Intervortex venous anastomosis is widely recognized as compensating for vortex vein congestion in pachychoroid spectrum diseases. However, determining the blood flow direction within the compensated drainage route is often challenging. Herein, we investigated the morphological patterns of vortex veins in eyes showing retrograde pulsatile vortex venous flow.

Design

Retrospective observational case series.

Subjects

Six hundred eighty-nine consecutive eyes with treatment-naive central serous chorioretinopathy, pachychoroid neovasculopathy, or polypoidal choroidal vasculopathy.

Methods

We reviewed the clinical records of patients with these pachychoroid spectrum diseases. Multimodal images including indocyanine green angiography (ICGA) and en face OCT were analyzed.

Main Outcome Measures

Intervortex venous anastomosis between superotemporal and inferotemporal vortex veins and the dominant site of dilated temporal vortex veins were determined in the eyes with retrograde pulsatile vortex venous flow in the temporal vortex veins.

Results

Twenty-two eyes with retrograde pulsatile vortex venous flow in the temporal vortex veins were identified utilizing early phase ICGA videos. In 9 eyes, retrograde pulsatile flow was detected in the superotemporal vortex veins, which were connected to the inferotemporal vortex veins via intervortex venous anastomoses. Among these cases, contralateral inferotemporal vortex vein dilatation was dominant in 7 eyes (77.8%), while superotemporal and inferotemporal vortex veins were symmetrically dilated in the other 2 eyes (22.2%). On the other hand, in 13 eyes, the retrograde pulsatile flow was detected in the inferotemporal vortex veins, which were linked to the superotemporal vortex veins via intervortex venous anastomoses. In these eyes, contralateral superotemporal vortex vein dilatation was dominant in 10 eyes (76.9%). Superotemporal and inferotemporal vortex veins were symmetrically dilated in 2 eyes (15.4%), while mainly inferotemporal vortex veins were dilated in 1 eye (7.7%).

Conclusions

In pachychoroid spectrum diseases, there are cases wherein congested venous blood might drain into the contralateral vortex veins via intervortex anastomoses. Overloaded contralateral vortex veins may, as a consequence, become more dilated than the primary congested vortex veins. Inversion of asymmetric vortex vein dilatation might thereby develop in pachychoroid spectrum diseases.
