Comparison of Lumbarperitoneal Shunt with the Stereotactic Ventriculoperitoneal Shunt for the Treatment of Refractory Idiopathic Intracranial Hypertension:A Case Report and Literature Review
Abstract BackgroundIdiopathic intracranial hypertension (IIH) or pseudotumor cerebri (PTC), is a disorder of young obese females and characterized by headache, papilledema with raised intracranial pressure in the absence of known pathological cause. Due to the uncertainty of etiology, it may lead to misdiagnosis and poor outcome. IIH is typically treated with shunts (lumbarperitoneal and ventriculoperitoneal shunting), but shunts are prone to malfunction and infection, resulting in many patients experiencing recurrent headaches post-treatment. Case presentationWe report a case of 41 years old obese female (BMI:30.9) with IIH who exhibited a history of hypertension (BP:150/100mmHg) and documented elevated intracranial pressure (OP:450mm H2O). After the failure of several medical treatments, the patient was offered LPS due to vision loss and headache, but postoperative symptoms (intermittent headache-mainly whole craniocerebral prickling pain accompanied by neck and shoulder pain) did not significantly relieve lasting for 11 years. Therefore, we considered the blockage of the primary shunt tube in the patient, and the patient with a small ventricle leads to some difficulty in ventricle puncture, then we had to treated with the stereotactic VPS(VPS)for her exacerbation symptoms. More surprisingly, the hypertension was within the normal range (<115/80mmHg) after the surgery (without antihypertensive medication).Purpose To compare the surgical therapeutic effects and complications of lumbarperitoneal shunt (LPS) and the stereotactic ventriculoperitoneal shunt (SVPS) for idiopathic intracranial hypertension.ConclusionCSF diversion with a ventriculoperitoneal shunt (VPS) or lumboperitoneal shunt (LPS) is usually performed when the main symptom is vision loss and it also stabilizes headache and papilledema. LPS significantly alleviates symptoms in the short term, but due to excessive shunt of LPS long time, it is easy to be complicated with iatrogenic Chiari malformation and slit ventricle syndrome. Therefore, we are encouraged to apply the SVPS on our patients for the favorable long-term outcome.
