PURPOSE

To evaluate efficacy and long-term results of primary hepatic venous stent placement following living-donor liver transplantation (LDLT).

METHOD AND MATERIALS

Percutaneous primary stent placement was attempted in 85 hepatic venous anastomotic stenoses of 62 patients. Patient follow-up included clinical and laboratory data collection, Doppler ultrasonography, computed tomography, and hepatic venography. The following parameters were documented retrospectively: technical success and complications, clinical success, recurrence, and long-term stent patency.

RESULTS

Technical success was achieved in 81 (95.3%) of 85 anastomoses (61 patients). Procedural complications occurred in six (9.8%) patients: partial stent migration (n = 2), acute angulation of the hepatic vein (n = 2), stent misplacement (n = 1), and acute hepatic vein thrombosis (n = 1). Clinical success was achieved in 49 (80.3%) of 61 patients. During the mean follow-up period of 108 (± 62) weeks, recurrence occurred in four (8.2%) of the 49 patients. They had restenoses at the just distal hepatic veins to the previously inserted stents, and two of them also had a new stenosis on the other anastomosis. Four (6.1%) patients showed asymptomatic thrombosis in the stent-inserted hepatic vein. One- and two-year cumulative patency rates of 53 stent-inserted hepatic veins in 41 patients who followed more than one year were 90.6% and 83.4%, respectively.

CONCLUSION

Primary stent placement is safe and effective treatment modality especially in patients with early-onset hepatic venous anastomotic stenosis following LDLT.
