ObjectiveTo investigate therapeutic method, curative effect, and prognosis of inferior vena cava (IVC) blocking Budd-Chiari syndrome (BCS) with thrombosis. MethodsClinical data of 128 BCS patients with membranous or short-segment occlusion of IVC as well as IVC thrombosis, who accepted interventional treatment in The Affiliated Hospital of Zhengzhou University from Apr. 2004 to Jun. 2012, were retrospectively analyzed. Comparison of the difference on effect indicators between predilation group and stent filter group was performed. ResultsThereinto, 9 patients with fresh IVC thrombosis were treated with agitation thrombolysis (agitation thrombolysis group), 56 patients were predilated by small balloon (predilation group), for the rest 63 patients, a stent filter was deployed (stent filter group). Besides 1 stent filter fractured during the first removal attempt and had to be extracted surgically in the stent filter group (patients suffered with sent migration), in addition, the surgeries of other patients were technically successful without procedure-related complication. effect indicators were satisfactory in all patients, and there were no statistical differences between predilation group and stent filter group in dosage of urokinase, urokinase thrombolysis time, hospital stay, and incidence of complication (P > 0.05), but the cost of predilation group was lower than that of stent filter group (P < 0.01). All of the 128 patients were followed-up postoperation, and the duration range from 18 to 66 months with an average of 44.2 months. During the follow-up period, reobstruction of the IVC was observed in 13 patients without thrombosis, of which 1 patient in agitation thrombolysis group, 6 patients in predilation group, and 6 patients in stent filter group. There was no significant difference in recurrence rate between predilation group and stent filter group (P > 0.05). Patients with recurrence got re-expansion treatment, and no stenosis or thrombogenesis recurred. ConclusionsAgitation thrombolysis for fresh IVC trombosis in the patients with BCS is safe and effective. Predilation and stent filter techniques are all effective in the treatment of BCS with chronic IVC thrombosis, but the former technique seems to be more economic.
