Abstract：
Reversal of blood flow has only been reported in the left internal jugular vein following interventions such as central venous catheter, dialysis shunt placement, or external compression from a tumor. We describe a rare case of chronic headache and hearing loss due to flow reversal in the left internal jugular vein and compensatory massive dilation of the right internal jugular vein. Flow reversal was caused by a prominent brachiocephalic trunk with subseqent compression of the vena brachiocephalica sinistra. Vascular anomalies and associated venous bypass circulation may be considered as a rare cause of non-specific malaise. Restoration of the physiological direction of blood flow should be discussed on an interdisciplinary basis given the unpredictable haemodynamic consequences.
摘要：
仅在中心静脉导管等干预措施后，左颈内静脉出现血流逆转。透析分流安置,或肿瘤的外部压迫。我们描述了由于左颈内静脉的血流逆转和右颈内静脉的代偿性大量扩张而导致的慢性头痛和听力丧失的罕见病例。血流逆转是由突出的头臂干引起的，并伴随着左臂头臂静脉的局部压缩。血管异常和相关的静脉旁路循环可能被认为是非特异性不适的罕见原因。鉴于不可预测的血液动力学后果，应在跨学科的基础上讨论恢复血液流动的生理方向。
