Objective To analyze the magnetic resonance angiography(MRA)imaging risk factors for short-term recurrence of patients with inferior vena cava type Budd-Chiari syndrome(BCS)after percutaneous angioplasty(PTA)treatment.Methods The preoperative clinical and MRA data of 90 patients diagnosed with inferior vena cava type BCS by digital subtraction angiography and treated with percutaneous angioplasty(PTA)were retrospectively analyzed.The patients were followed up for 12 months.The clinical data of relapse group and non-relapse group were compared.Multivariate logistic regression was used to analyze the MRA imaging risk factors for the short-term recurrence of patients with inferior vena cava type BCS after PTA treatment.Results Of 90 patients,46(51.11％)cases relapsed.Compared with non-relapse group,the proportions of the patients with enlarged caudate lobe of liver,length of obstruction ≥3.0 cm,maximum width of proximal lumen of obstruction＜25 mm were higher in relapse group(P＜0.05).Multivariate logistic regression analysis showed that enlarged caudate lobe of liver[OR=10.803,95％CI(2.749-42.460),P＜0.01],length of obstruction ≥3.0 cm[OR=19.471,95％CI(4.739-79.995),P＜0.01]and maximum width of proximal lumen of obstruction＜25 mm[OR=3.955,95％CI(1.156-13.534),P＜0.05]were the independent MRA imaging risk factors for short-term recurrence in patients with inferior vena cava type BCS after PTA treatment.Conclusion Enlarged caudate lobe of liver,length of obstruction ≥3.0 cm and maximum width of proximal lumen of obstruction＜25 mm were the independent MRA imaging risk factors for short-term recurrence of patients with inferior vena cava type BCS after PTA treatment.
