Clinical analysis of 2643 cases of trigeminal neuralgia treated by microvascular decompression / 中华外科杂志

<p><b>OBJECTIVE</b>To evaluate the clinical effects of microvascular decompression in treating trigeminal neuralgia.</p><p><b>METHODS</b>Surgical experience and operative findings of 2643 cases of trigeminal neuralgia treated by microvascular decompression were analyzed retrospectively.</p><p><b>RESULTS</b>Two thousand four hundred and eighty-seven of 2643 cases were cured, 76 cases were ineffectiveness, 48 cases were effectiveness and 31 were ineffective. One patient died. Two thousand one hundred and thirty-six cases were followed up in 3-240 months, 1918 cases were cured, 85 cases were obviously effective, 39 cases were effective and 30 were ineffective. Sixty-four cases were pain relapsed and 37 cases were cured by second operation among them.</p><p><b>CONCLUSION</b>The etiology of trigeminal neuralgia is that the unusual vascular oppress the root entry zone, and arachnoid membrane circling the nerve is thickened and sticked. To untie the arachnoid membrane and decompress the offending vascular is the effective methods in treating trigeminal neuralgia.</p>

Therapeutic evaluation of microvascular decompression in patients with trigeminal neuralgia associated with hypertension / 中华外科杂志

<p><b>OBJECTIVE</b>The aim of work was to evaluate the efficacy of microvascular decompression (MVD) in patients with trigeminal neuralgia (TN) associated with hypertension.</p><p><b>METHODS</b>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.</p><p><b>RESULTS</b>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.</p><p><b>CONCLUSIONS</b>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.</p>
