Pathological changes of cerebral arterioles around hematoma at acute stage in patients with intracerebral hemorrhage / 临床神经病学杂志

ABSTRACT

Objective To observe the pathological changes of cerebral arterioles around hematom in patients with acute period of intracerebral hemorrhage. Methods Brain tissue fragments were collected from the drainage effluents of 43 patients who received mini-invasive puncture drainage treatment of acute intracereal hemorrhage. Pathological changes of arterioles were analyzed under light microscope by routine HE and Congo red staining, respectively. Results The primary pathological changes of cerebral arteriole around hematom was arteriosclerosis and hyaline degeneration, which accounted for 28 cases (65.12%). Other pathological etiological factors included atherosclerosis in 3 cases (6.98%) and thrombosis in 5 cases (11.63%). Light microscopy also showed neutrophilic granulocytes sticking on the endothelial cells and exuding around vessels in 10 cases (23.26%) from 6h to 4d, and mini-focal hemorrhage in 8 cases (18.6%) from 24 to 48h.Conclusions Arteriosclerosis is the principal pathological etiology for spontaneous intracerebral hemorrhage. Neutrophilic granulocytes infiltrating was one of the most important pathological changes in acute stage of intracerebral hemorrhage.
