Résumé
Endovascular treatment (EVT) by percutaneous transluminal angioplasty (PTA) or stent is the first-line treatment for hepatic artery stenosis (HAS) after liver transplantation, but there are no guidelines to help choose between PTA and stent. Retrospective review of HAS EVT after liver transplantation, between 1999 and 2017. HAS was treated by PTA or stent. We report EVT primary effectiveness, arterial patency after 1 year of follow-up, complications, HAS recurrence rate; comparing PTA to stent. Fifty-two HAS were diagnosed in 42 patients. We performed 51 EVT; 34 PTA (66.7%) and 16 stents (31.4%). Global primary EVT effectiveness was 86.3%: 82.3% after PTA and 100% after stent (P = 1.00 after propensity score matching). Recurrent HAS was found in 22.0% of cases: 29.4% after PTA and 6.2% after stenting, (P = .053 after propensity score matching). Patency rate without recurrent HAS or HAT at 12 months was 73.5% with PTA and 93.8% with stent (P = .09), and globally this was 92.8%. There were 7.8% complications: 2.9% after PTA, 12.5% after stenting (P = .23). Primary effectiveness was the same for PTA and stenting. There was a strong trend toward more HAS recurrence after PTA than after stenting suggesting that HAS should benefit from primary stenting.

BACKGROUND
Endovascular treatment (EVT) by percutaneous transluminal angioplasty (PTA) or stent is the first-line treatment for hepatic artery stenosis (HAS) after liver transplantation, but there are no guidelines to help choose between PTA and stent.
METHODS
Retrospective review of HAS EVT after liver transplantation, between 1999 and 2017. HAS was treated by PTA or stent. We report EVT primary effectiveness, arterial patency after 1 year of follow-up, complications, HAS recurrence rate; comparing PTA to stent.
RESULTS
Fifty-two HAS were diagnosed in 42 patients. We performed 51 EVT; 34 PTA (66.7%) and 16 stents (31.4%). Global primary EVT effectiveness was 86.3%: 82.3% after PTA and 100% after stent (P = 1.00 after propensity score matching). Recurrent HAS was found in 22.0% of cases: 29.4% after PTA and 6.2% after stenting, (P = .053 after propensity score matching). Patency rate without recurrent HAS or HAT at 12 months was 73.5% with PTA and 93.8% with stent (P = .09), and globally this was 92.8%. There were 7.8% complications: 2.9% after PTA, 12.5% after stenting (P = .23).
CONCLUSION
Primary effectiveness was the same for PTA and stenting. There was a strong trend toward more HAS recurrence after PTA than after stenting suggesting that HAS should benefit from primary stenting.
