The sonographic aspect of the gallbladder in seven cases of haemobilia is analysed. The changes include a diffuse echogenic gallbladder content during the initial stage. Later, irregular shaped inhomogeneous non shadowing masses are seen in the dependent parts of the lumen. This variable aspect was studied in an experimental model by percutaneous injection of blood in the gallbladder of Guinea pigs. The hyperechoic gallbladder content, seen early after injection is a transitory phenomenon which seems related to red cell aggregation before coagulation occurs. During the later stage the intraluminal masses were shown by histology to represent bloodclots. In a patient the observation of such a rapid evolution from diffuse hyper-reflectivity to less reflective masses is strongly suggestive of haemobilia.
分析了7例胆血症患者胆囊的超声表现。其变化包括初期胆囊内容物呈弥漫性回声增强。之后,在管腔的下垂部位可见形状不规则、不均匀的无回声团块。通过经皮向豚鼠胆囊内注射血液,在实验模型中研究了这种多变的表现。注射后早期出现的高回声胆囊内容物是一种短暂现象,似乎与凝血前红细胞聚集有关。后期经组织学检查显示管腔内团块为血凝块。在一名患者中,观察到从弥漫性高回声迅速演变为低回声团块,强烈提示为胆血症。
