Splenic artery steal syndrome (SASS) is common complication in liver transplantation and diagnosed by conventional angiography by enlarged splenic artery and dynamic findings. The aim of this study was to determine MDCT-A findings of splenic artery steal syndrome and develop some diagnostic criteria. 10 patients was diagnosed by celiac angiography as splenic artery steal syndrome in 136 liver transplant patients. In eight of them MDCT-A was performed. Axial and coronal MIP images were obtained in arterial and portal phase. We measured the diameter of celiac truncus, splenic, left gastric, common hepatic, superior mesenteric artery, and transplant hepatic artery. The size of spleen, the ratio of splenic artery to common hepatic artery, the ratio of splenic artery to transplant hepatic artery, the diameter of portal vein and superior mesenteric vein was noted. The control group consists of liver transplant patients with normal liver enzyme levels. We performed student t test for statistical examination. The diameter of splenic artery (p<0.05), the size of spleen (p<0.01), and the ratio of splenic artery to transplant hepatic artery (p<0.05) was statistically significant between two groups. The diameter of splenic artery was larger than 4 mm in all patients in study group. The conventional angiography was mandatory in diagnosis of SASS. In patients suspected for SASS as cilinically MDCT-A can be used as first step imaging modality for early diagnosis.
