摘要

Background

Internal jugular vein stenting is a treatment for intracranial hypertension caused by internal jugular vein stenosis (IJVS). Reports on this procedure remain limited, and stent migration is an exceptionally rare complication.

Case presentation

A patient in their 20s presented with headache, anxiety, depression, and sleep disturbances. Imaging revealed left transverse sinus stenosis, leading to a diagnosis of idiopathic intracranial hypertension (IIH). Symptoms initially improved following left transverse sinus stent implantation. However, three months after surgery, the patient developed recurrent headaches. Digital subtraction angiography (DSA) revealed restenosis of the left transverse sinus and new stenosis of the right internal jugular vein (IJV). Stenting at both sites significantly relieved intracranial hypertension. However, the patient later developed palpitations and peripheral edema. Follow-up angiography confirmed the migration of the right IJV stent into the right pulmonary artery.

Conclusion

Stent migration should be suspected if palpitations and peripheral edema occur after placement. In extreme cases, IJV stenting can lead to stent migration into the pulmonary artery. For asymptomatic patients, short-term conservative management is feasible. In the present case, the migrated stent caused no significant harm to the patient.
