【摘要】 目的探讨胃肠道血管畸形（GIVM）之临床病理特点。方法对6例GIVM病例进行临床和病理学观察分析，并复习文献。结果上消化道者以大出血为主要表现，下消化道者以慢性出血为主；多位于胃上1／3处，病灶小，呈点状糜烂或浅溃疡；胃外者结肠多见，多有溃疡穿孔或肠管变形等。前者粘膜下层可见恒径之动静脉；后者肠壁全层可见薄壁扩散之血管穿插。结论GIVM并不少见，凡上消化道难以止住之大出血，应想到此病。纤维胃镜为主要诊断手段，手术为主要治疗方法；病理检查要全面，重视巨检和准确取材，不要把继发病变当成主因。更多还原

【Abstract】 To investigate the clinical and pathological features of gastrointesinal vascular malformation (GIVM).Methods The resected specimens from 6 cases with GIVM were analyzed clinically and patholgically and recent literatures werereviewed.Results GIVM was not very rare. Clinically the acute ulcerative lesions weer located most frequently in the upperthird of stomach and caused massive bleeding.The lesions were small and showed dotted erosions or shallow ulceration .the chiefmanifestation of GIVM of the lower gastrointestinal tract was chronic bleeding.The extra-gastric lesion was often found in the colonand associated with ulceration,perroraton,deformation of the inestinal wall.etc.In th former cases,arteries and verins of uni-form caliber were seen in submucosa but in the latter cases some thin and distended blood vessels traveld through all layers of in-testine.Conclusions GIVM is not rare.This disease should be condsidered whe one encounters the intractable bleeding of up-per gastrointestinal tract,and is the important diagnostic measure.Gastro-resection is the principal method for thetreatment.Besides,overall pathologic examination should be done,gross observaion must be paid attention to,specimen-takingmust be accurate and the aecondary pathologic changes can neve be considered as the main cause of bleeding.更多还原
