The short-term results showed a normalization of blood pressure with a markedly reduced antihypertensive drug regimen in 7 patients. To determine the longer-term outcome concerning blood pressure and secondary organ damage after neurovascular decompression, we studied these 8 operated patients prospectively for a mean follow-up of 3.5 years after surgical intervention.\n          <\/jats:p>\n          <jats:p>\n            <jats:bold>\n              <jats:italic>\n                <jats:bold>\n                  <jats:italic>Methods<\/jats:italic>\n                <\/jats:bold>\n                \u2014\n              <\/jats:italic>\n            <\/jats:bold>\n            Eight hypertensive patients who had undergone microsurgical decompression were monitored every 6 months after surgery to assess blood pressure (by 24-hour ambulatory pressure readings) and the need for antihypertensive medication. To evaluate secondary organ damage, echocardiographic assessment of left ventricular hypertrophy, fundoscopic assessment of hypertensive lesions, and analysis of renal function and proteinuria were done.\n          <\/jats:p>\n          <jats:p>\n            <jats:bold>\n              <jats:italic>\n                <jats:bold>\n                  <jats:italic>Results<\/jats:italic>\n                <\/jats:bold>\n                \u2014\n              <\/jats:italic>\n            <\/jats:bold>\n            Three of the 8 operated patients remained normotensive in the long-term period with decreased antihypertensive medication. Two patients required gradual increases of antihypertensive medication after the first postoperative year, after which arterial blood pressure levels were 10% to 15% lower than preoperative levels. Three patients suffered serious cardiovascular and renal complications, with the incidence of lethal intracerebral hemorrhage in 1 patient and end-stage renal disease in 2 patients, of whom 1 experienced sudden cardiac death.\n          <\/jats:p>\n          <jats:p>\n            <jats:bold>\n              <jats:italic>\n                <jats:bold>\n                  <jats:italic>Conclusions<\/jats:italic>\n                <\/jats:bold>\n                \u2014\n              <\/jats:italic>\n            <\/jats:bold>\n            The long-term results verify that microsurgical decompression is a successful alternative therapy in a certain subgroup of patients with arterial hypertension due to neurovascular compression. However, the relevance of the looping artery in the other cases, who did not improve, is not clear. Prospective studies to elucidate the pathophysiological role of neurovascular abnormalities and arterial hypertension are needed.\n          <\/jats:p>","DOI":"10.1161\/hs1201.099799","type":"journal-article","created":{"date-parts":[[2007,10,10]],"date-time":"2007-10-10T17:48:04Z","timestamp":1192038484000},"page":"2950-2955","update-policy":"http:\/\/dx.doi.org\/10.1161\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":21,"title":["Long-Term Results After Microvascular Decompression in Essential Hypertension"],"prefix":"10.1161","volume":"32","author":[{"given":"H.","family":"Frank","sequence":"first","affiliation":[{"name":"From the Medical Department IV\/Nephrology (H.F., H.P.S., K.H.) and Clinic of Neurosurgery (R.N., R.F.), University Erlangen, and Medical Department IV\/Nephrology, University Frankfurt\/Main (H.G.)
