Long-Term Outcomes of Endoluminal Sharp Recanalization of Occluded Inferior Vena Cava in Budd-Chiari Syndrome.

Abstract

To report the long-term results of endoluminal sharp recanalization of occluded inferior vena cava (IVC) in patients with the Budd-Chiari syndrome (BCS). Seventy-two consecutive patients with BCS and IVC occlusion underwent endoluminal recanalization of the IVC occlusion during a 6-year period. BCS with occlusive IVC was detected by reviewing patient history and color Doppler ultrasonography. Data on technical success, morbidity, mortality, complications, and color Doppler sonographic outcome were collected and analyzed. Seventy-seven recanalizations were performed in 72 patients. Technical success (patent IVC with good blood flow) was achieved in 70 (97.4%) patients. No perioperative death was observed. Six complications were found during recanalization, and 10 complications were found for total interventional procedures. The complication rates were 7.8% and 7.3% for recanalization and total procedure, respectively. Bleeding of access veins was the most common complication, and 2 patients showed slight rupture of IVC. The postoperative IVC diameter and blood speed of IVC increased significantly. Fifty-seven patients (79.2%) were clinical cured, and 2 patients (2.8%) showed no improvement. The 1-year, 3-year, and 5-year primary patency rates were 92.5%, 86.8%, and 77.3%, respectively. The second patency rates were 100.0%, 97.8%, and 91.8% for 1, 3, and 5 years, respectively. There were 2 deaths during follow-up. Endoluminal sharp recanalization of occluded IVC in patients with BCS is safe and effective with good long-term outcomes.
