In cases of liver cirrhosis with hepatocellular carcinoma and varix, TAE or TSE has been undertaken frequently. In these managements, splenic infarction occurs incidentally.
In this study, 11 cases of splenic infarction after these managements were analysed ultrasonographically.
US findings of splenic infarction were hypoechoic mass with short linear strong echo (SLSE), honeycomb pattern or wedge-shaped lesion with wide basis.
In accordance with above US findings and number or extension of splenic infarction, it was classified into 3 groups, i.e. single, multiple and diffuse type. However, frequency of each type was almost same and 3, 5 and 3 cases were obserbed respectively.
In 3 cases of diffuse type, abscess formation were obserbed in 2 cases but another type had no complication of it.
An average period from the onset of infarction to the date detected by US was 11 days. It wasslightly earlier to the period of increasing of thrombocytes in peripheral blood.
Splenic size was decreased in diffuse type and multiple type but in single type it was not changed. If anechoic lesion appears during the observation of splenic infarction, it must be considered that the complication of splenic abscess or parasplenic abscess was occured.
