Imaging findings and differential diagnosis of hepatic sinusoidal occlusion syndrome and Budd-Chiari syndrome

Objective To retrospectively analyze the clinical and imaging manifestations differential points between hepatic sinusoidal obstruction syndrome (SOS) and Budd-Chiari syndrome (BCS). Material The clinical symptoms, laboratory examination and imaging findings of 15 cases of hepatic sinusoidal obstruction syndrome and 33 cases of Budd-Chiari syndrome were statistically analyzed, find the identification points. The study used the Fisher test, P values of 0.05 or less were considered to indicate significant differences. The retrospective study was approved by the hospital's ethics committee. Results Laboratory tests: There were significant differences in total protein reduction rate (66.7% vs 9.1%, p༜0.01), albumin reduction rate (66.7% vs 9.1%, p༜0.01), Gamma-glutamyltransferase elevation rate (100% vs 6.1%, P༜0.01), alkaline phosphatase elevation rate (60% vs 6.1%, p༜0.01), and abnormal rate of prothrombin time (100% vs 21.2%, p༜0.01) between the two groups (BCS vs SOS). It also indicates that the liver function of SOS patients is more seriously impaired. Image findings: The following image findings were observed significant more frequently in SOS than in BCS and were statistically significant: gallbladder wall thickening (66.7% vs 78.2%, p༜0.01), ascites (80% vs 27.3%, p༜0.01), cloverleaf or claw-like shapes (80% vs 0%, p༜0.01). The following images appeared more frequently in BCS than in BCS and were statistically significant: caudate lobe enlargement (33.3% vs 75.8%, p༜0.01), collateral circulation (46.7% vs 93.9%, p༜0.01), diffuse patchy enhancement (20% vs 93.9%, p༜0.01), homogeneous in delayed phase (13.3% vs 90.1%, p༜0.01). Conclusion To Identification of SOS and BCS should be based on the patient's laboratory examination and imaging findings to improve diagnostic accuracy.
