The Differential Value Of The Direction Of Vascular Displacement In The Carotid Space In The Lymph Node-derived And Neurogenic Lesions Of The Neck ?-? Area

ObjectiveTo investigate the identification value of vascular displacement direction in carotid space on lymph node-derived and neurogenic lesions in neck II-IV area.MethodsA total of 33 patients whose lesions were pathologically confirmed in the neck II-IV area from 1st January 2017 to 15th April 2019 were collected,including lymph node-derived lesion(n=26,including seven patients of lymph node tuberculosis,eight patients of lymph node metastasis,seven patients of lymphoma and four patients of lymphnoditis)and neurogenic lesion(n=7,including six patients of schwannoma and one patient of neurofibroma).Besides the obvious signs of lesion size,boundary,shape,density and enhancement ways and degree,the vascular displacement direction received more attention.ResultsThere were no significant differences in size(Z=-1.456,P=0.145),boundary(?~2=0.480,P=0.652),shape(?~2=2.257,P=0.190),density(?~2=1.451,P=0.378),schedule of enhancement(?~2=1.188,P=0.664),and degree of enhancement(?~2=5.579,P=0.084)between two groups.In contrast,26 patients(100%)with lymph node lesion had inward displacement,carotid space vascular moving inside,six patients with neurogenic lesion(85.7%)had outward displacement,and one patient with neurogenic lesion(14.3%)had inward displacement,with statistically significant differences(?~2=27.238,P=0.000).ConclusionThe direction of vascular displacement in carotid space can be used to identify the lesion from lymph node or nerve in the neck II-IV area.
