摘　　要：BACKGROUND Hepatic artery stenosis is a complication of orthotopic liver transplant occurring in 3.1%-7.4%of patients that can result in graft failure and need for retransplantation.Endovascular therapy with angioplasty and stenting has been used with a high degree of technical success and good clinical outcomes,but tortuous hepatic arteries present a unique challenge for intervention.Suitable stents for this application should be maneuverable and conformable while also exerting adequate radial force to maintain a patent lumen.CASE SUMMARY Herein we report our experience with a neurovascular Wingspan stent system in a challenging case of recurrent hepatic artery stenosis and discuss the literature of stenting in tortuous transplant hepatic arteries.CONCLUSION Wingspan neurovascular stent is self-expanding,has good conformability,and adequate radial resistance and as such it could be added to the armamentarium of interventionalists in the setting of a tortuous and stenotic transplant hepatic artery.BACKGROUND Hepatic artery stenosis is a complication of orthotopic liver transplant occurring in 3.1%-7.4% of patients that can result in graft failure and need for retransplantation.
