PURPOSE: To present results of a 9 year followup of percutaneous transluminal angioplasty (PTA) and stents placement in patients with Budd-Chiari Syndrome (BCS) and to evaluate the clinical value and applicability of this approach. MATERIALS AND METHODS: 44 consecutive patients with BCS (25 male and 19 female; average age, 42.6 years; age range, 19-77 years) were treated with PTA and stents during a 9-year period. The mean duration of symptoms was 46 months. Underlying active malignancy was the cause of occlusion in 5 patients. 3 patients had a history of taking oral contraceptives. The obstructed inferior vena cava (IVC) or hepatic vein (HV) were first dilated by a percutaneous transluminal balloon, and then a self-expanding stent was placed. Clinical patency was defined as absence or improvement of symptoms. Clinical follow-up was supplemented with colour Doppler sonography, CT scan, or both. RESULTS: Technical success was achieved in 97.2% (35/36) IVC and 83% (10/12) HV PTA and stents. Significantly, the IVC pressure decreased from 2.7 kPa (SD = 0.3) to 1.5 kPa (SD = 0.4) and HV pressure dropped from 2.3 kPa (SD = 0.4) to 1.3 kPa (SD = 0.2). The symptoms and signs disappeared or were relieved after operation in most of the patients. A few serious related complications including one stent migration and one pulmonary emboli occurred and were resolved in time. Patients were followed for a mean of 44 months (range 3-102). Short- and long-term results were satisfactory except for 3 patients (9.4%, 1 IVC, 2 HV) who presented with a restenosis or thrombosis and underwent additional therapy. There were 5 deaths owing to underlying malignant disease 3-17 months after the procedures. CONCLUSION: PTA and stent placements proved a safe and effective treatment in BCS and had a good long-term outcome and should be considered in patients who have symptoms or have no adequate alternative therapy.
