Budd-Chiari Syndrome in Young Chinese: Clinical Characteristics, Etiology and Outcome of Recanalization from a Single Center.

Purpose: We aimed to characterize the clinical profile, etiology, and outcomes of young Chinese patients with Budd-Chiari syndrome treated with recanalization.
Methods: A total of 35 consecutive young patients (≤25 years of age) with primary Budd-Chiari syndrome treated with recanalization at our center were enrolled in this study between March 2011 and December 2014. Data on baseline information, etiology tests, therapeutic recanalization strategies, and follow-up were collected.
Results: The most common clinical feature was ascites, present in 33 cases (94%). Hepatic vein obstruction was present in 60% (21/35) of patients, inferior vena cava obstruction in 3% (1/35), and combined obstruction in 37% (13/35). The most common risk factor for thrombosis was hyperhomocysteinemia (14/35, 40%). Recanalization was technically successful in 32 of 35 patients (91%), and clinically successful in 28 of these 32 patients (88%). The cumulative 1- and 3-year primary patency rates were 75.2 and 54.3%, respectively. The cumulative 1- and 3-year secondary patency rates were 89.3 and 89.3%, respectively. The cumulative 1- and 3-year survival rates were 96.9 and 93.8%, respectively.
Conclusion: In this study, the most common type of lesion was hepatic vein obstruction, the most common thrombotic risk factor was hyperhomocysteinemia, and recanalization resulted in good mid-term outcomes in young Chinese patients with Budd-Chiari syndrome.
