To evaluate the role of the omohyoid muscle anatomic variants as a possible reversible cause of internal jugular vein extrinsic compression.
We describe a chronic cerebro-spinal venous insufficiency patient, who presented a omohyoid muscle entrapment of the internal jugular vein, confirmed by both magnetic resonance venography and ultrasound investigation. A omohyoid muscle surgical transection together with a patch angioplasty was performed.
The surgical procedure led to both IJV flow restoration and neurological improvement.
The omohyoid muscle compression on the internal jugular vein seems to be a possible cause of venous obstruction, but several anatomical and patho-physiological aspects need further investigations. Such picture might cause balloon venous angioplasty inefficacy and needs to be preoperatively considered.
评估肩胛舌骨肌解剖变异作为颈内静脉外在压迫可能的可逆性原因的作用。
我们描述了一名慢性脑脊髓静脉功能不全患者，其颈内静脉被肩胛舌骨肌卡压，磁共振静脉造影和超声检查均予以证实。实施了肩胛舌骨肌手术横断并进行补片血管成形术。
手术操作使颈内静脉血流恢复且神经功能得到改善。
肩胛舌骨肌对颈内静脉的压迫似乎是静脉阻塞的一个可能原因，但几个解剖学和病理生理学方面需要进一步研究。这种情况可能导致球囊静脉血管成形术无效，术前需要加以考虑。
