Münchausen Syndrome as an Unusual Cause of Pseudo-resistant Hypertension: A Case Report

Münchausen syndrome can be characterized by simulated illness, pathological lying and wandering from place to place (the patient typically presents to numerous hospitals). Individuals with elevated blood pressure due to non-adherence to medication have the so-called pseudo-resistant hypertension. A 45-year-old woman was admitted to hospital on an emergency basis because of a hypertensive crisis. Despite combination antihypertensive treatment, normalization of blood pressure was not achieved and a device to produce a therapeutic arteriovenous fi stula was implanted. Aft er the procedure, a signifi cant increase in pulmonary artery pressure was observed and closure of the fistula was performed by implantation of the stent graft . The suspicion was raised that the patient had not been taking her prescribed medications. Therefore, blood samples were taken and the serum was analyzed for presence of the prescribed drugs (atorvastatin, bisoprolol, chlorthalidone, clonidine, doxazosin, furosemide, nitrendipine, oxazepam and valsartan). The results confirmed suspected failure of the patient to take the prescribed medications. Münchausen syndrome is usually first suspected when inexplicable laboratory test results are noted. To our knowledge, this is the first reported case of Münchausen syndrome with pseudo-resistant hypertension leading to the implantation of a device to produce a therapeutic arteriovenous fi stula.
