Background
Budd–Chiari syndrome is a heterogeneous group of disorders characterized by hepatic venous outflow obstruction at the level of the hepatic venules, the large hepatic veins, the inferior vena cava till its junction with the right atrium. The classic triad of abdominal pain, ascites, and hepatomegaly is observed in the vast majority of patients with Budd-Chiari syndrome. The diagnosis of BCS is made by clinical presentation and confirmatory investigations. Standard laboratory investigations are rarely helpful in establishing the diagnosis, because abnormal liver function tests are not specific for BCS, real time Gray-scale sonography combined with colour flow is considered by some to be the initial imaging technique. The recommended stepwise therapeutic algorithm of BCS is mainly by medical treatment with anticoagulation, angioplasty with or without stenting, TIPS of surgical shunting and liver transplantation if indicated. TIPS is a common teqnique used in BCS and TIPS stent occlusion is major complication.
Objectives
To identify the possible risk factors and predictors of stent occlusion in primary BCS patients who underwent TIPSS.
Patients and Methods
The studied patients were selected from patients presented to Budd Chiari outpatient clinic. Tropical medicine department in Ain Shams University hospitals. total number of cases during the study period was 76 cases fulfilling the inclusion criteria, they were divided in 2 groups according to patency of TIPS stent and comparing both groups regarding their pre and post TIPS data.
Results
The mean age of the patients was (29.29 ± 7.92) with female predominance. FVLM (69.7%) & MTHFRD (67.1%) were the most common causes of BCS in the studied patients. positive and higher CRP results were found in the occluded stent patients than patent groups. also, higher TLC levels were found in the occluded TIPS stent patients.
Conclusion
Identifying these risk factors may help predict the outcome of TIPS stent patency.
