Vessels that were considered to be responsible for HFS were determined by reviewing the brain magnetic resonance imaging, magnetic resonance angiography, and surgical video. Blood pressure measurements were performed 1\u00a0day before (preoperative) and 7\u00a0days after (postoperative) the MVD surgery. Pre\u2010 and postoperative blood pressure measurements were compared.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>A total of 374 patients were included in the study, with 118 (31.6%) male patients, age 53.8\u00a0\u00b1\u00a09.9\u00a0years old, and 141 (37.7%) patients with hypertension. Systolic blood pressure had statistically significant decrease in patients with (134.5\u00a0\u00b1\u00a08.2\u2013132.6\u00a0\u00b1\u00a09.1\u00a0mmHg, <jats:italic>p<\/jats:italic>\u00a0=\u00a0.01) or without (125.6\u00a0\u00b1\u00a09.1\u2013123.8\u00a0\u00b1\u00a010.0\u00a0mmHg, <jats:italic>p<\/jats:italic>\u00a0=\u00a0.01) hypertension.
