Clinical Study on the Efficacy of Microvascular Decompression in the Treatment of Neurogenic Hypertension
260 participantsStarted 2021-03
Plain-language summary
Hypertension has always been a threat to human health, so the prevention and treatment is of great significance. At present, the treatment of primary hypertension is mainly drug treatment, but many patients can not control their blood pressure in the normal range. Therefore, it is urgent to explore new and effective treatment methods.
Microvascular compression type of neurogenic hypertension is mainly due to abnormal tortuous vascular pulsatile compression of blood pressure center - rostral ventrolateral medulla (RVLM), resulting in the release of sympathetic active substances, leading to hypertension. The purpose of this study is to explore the efficacy and safety of microvascular decompression for hypertension in patients of hemifacial spasm complicated with hypertension, and to explore the common characteristics of patients with effective decompression.
The type of study design was prospective cohort study. According to certain inclusion and exclusion criteria, patients with RVLM compression were treated with RVLM decompression at the same time of facial nerve decompression. Patients who were followed up for 3 months were taken as control group, and the blood pressure of the two groups were measured after 3 months. The main outcome measure was 24-hour ambulatory systolic blood pressure change from baseline to 3 months.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
