1984年若杉报告星状神经节封闭治疗变应性鼻炎,取得了良好效果。既往认为在花粉症时,由于释放组胺而使血管扩张、粘膜水肿,故通常使用血管收缩剂治疗。而星状神经节封闭可使血管扩张而诱发变态反应症状。作者认为变应性鼻炎的组织学特点为伴有血管扩张的循环障碍及上皮下水肿。从局部血液循环角度考虑,能使血循环改善的星状神经节封闭是有效的治疗方法。 1985年3～4月,作者对83例杉树花粉症患者行星状神经节封闭,每周3次,左右侧交替进行。行5次后症状完全消失者14例(16.9％);症状大部消失者36例(43.4％);症状稍轻者31例(37.3％);无变化2例(2.4％);无恶化者。前二者共约60％,加上症状稍有改善者共97.6％。行10次封闭后全部病例症状均有改善,其中前二者总计达77％。最早消失的症状为眼部搔痒感,大部病例封闭2 1984 Watson reported stellate ganglion block treatment of allergic rhinitis and achieved good results. In the past that in hay fever, due to the release of histamine and vasodilation, mucosal edema, it is usually treated with vasoconstrictors. Stellate ganglion closure can make vasodilation and induce allergic symptoms. The authors suggest that the histological features of allergic rhinitis are circulatory disorders associated with vasodilation and subepithelial edema. From the perspective of the local blood circulation, can make the blood circulation improved stellate ganglion closure is an effective treatment. From March to April 1985, the authors blocked the stellate ganglion in 83 cases of cedar hay fever patients, three times a week, alternately on the left and right sides. There were 14 cases (16.9%) with complete disappearance of symptoms after 5 times of treatment, 36 cases (43.4%) with most symptoms disappeared, 31 cases (37.3%) with mild symptoms, 2 cases without change (2.4%), . A total of about 60% of the former two, together with a slight improvement in symptoms a total of 97.6%. All cases were improved after 10 occlusions, of which the former two totaled 77%. The earliest symptom of the disappearance of the eye itching, most of the cases closed 2
