Different types of Budd Chiari syndrome showed different circulation directions / 介入放射学杂志

Objective To improve the knowledge for flow direction of renal spleen circulation in Budd Chiari syndrome and effects in treatment. Methods Two Budd Chiari syndrome patients with reno splenic venous shunt were treated by PTA, and the circulation directions were investigated. Results One case with hepatic vein occlusion showed the circulation from left renal spleen vein to IVC; another case with IVC stenosis proximal to heart showed the flow direction from spleen left renal vein to varices and finally to SVC. The circulation disappeared after treatment with PTA.Conclusions The direction of circulation in different types of Budd Chiari with portal hypertension may be different and should be identified clearly for a suitable management.
