Abstract
Idiopathic Intracranial Hypertension (IIH) or Pseudotumor Cerebri (PTC) is a disorder of young obese females and characterized by headache, papilledema and raised intracranial pressure. However, it is in the absence of known pathological cause. Due to the uncertainty of etiology, it may lead to misdiagnosis and grave clinical prognosis. IIH is typically treated with Lumboperitoneal Shunting (LPS) and Ventriculoperitoneal Shunting (VPS), but shunts are prone to dysfunctions and infection, resulting in recurrent headaches in many patients after this treatment. We report a case of 41-year-old obese female (BMI: 30.9) with IIH, who has a history of hypertension (Blood pressure: 150/100 mmHg) and elevated intracranial pressure (Open pressure: 450 mmH2 O). After the failure of several medical treatments, the patient was offered LPS because of vision loss and headache, but the postoperative symptoms (intermittent headache, mainly total craniocerebral prickling pain with neck and shoulder pain) were not significantly relieved for 11 years. Therefore, considering the blockage of the primary shunt tube and the small ventricle in the patient, it has difficulty in puncture ventricle puncture. We have to treat with the stereotactic VPS (SVPS) for her exacerbation symptoms. More surprisingly, the hypertension was in the normal range (<115/80 mmHg) after the surgery (without taking antihypertensive medication). To compare the surgical therapeutic effects and complications of LPS and the SVPS in the treatment of idiopathic intracranial hypertension. Cerebrospinal Fluid (CSF) diversion with VPS or LPS is usually performed when the main symptom is vision loss; it also stabilizes headache and papilledema. LPS significantly alleviates symptoms in the short term, but due to excessive shunt of LPS for a long time, it is easy to be complicated with Chiari malformation and slit ventricle syndrome. Therefore, we encourage operating the SVPS on our patients for the favorable long-term outcome.
