title: [Therapeutic evaluation of microvascular decompression in patients with trigeminal neuralgia associated with hypertension].
abstract: OBJECTIVE
  The aim of work was to evaluate the efficacy of microvascular decompression (MVD) in patients with trigeminal neuralgia (TN) associated with hypertension.
  
  
  METHODS
  Five hundred and thirty-eight cases of TN associated with hypertension treated with MVD were retrospectively analyzed, all the cases were treated with MVD in the zone of the ventrolateral medulla oblongata and inspected postoperative blood pressure.
  
  
  RESULTS
  Among 538 cases, 341 cases (63.4%) had cure result, 71 cases (13.2%) had obvious effectiveness, 53 cases (9.8%) had effectiveness, and 73 cases had no effectiveness. Four hundred and eighty-three cases have been followed 1.0 approximately 15.8 years, mean 6.3 years. At the time of their follow-up, 313 cases had cure result, 63 cases had obvious effectiveness, 42 cases had effectiveness and 65 cases had no effectiveness.
  
  
  CONCLUSIONS
  It was pathogenesis of nedulla oblongata by abnormal vascular tab, long-term aching stimulation and emotional stress. It was an effective method to treat TN associated with hypertension with MVD in this zone.
