Diagnosis and management of hepatic artery in-stent restenosis after liver transplantation by optical coherence tomography: A case report

Figure 2 Visceral arteriography and optical coherence tomography. A: Visceral arteriography diagnosis with hepatic artery tortuosity and doubtful significant intra-stent diameter reduction and intrahepatic flow reduction. The yellow arrow indicates the possible stenosis area, to be confirmed further with an intravascular method; B: OCT diagnosis of severe stenosis due neointimal hyperplasia and focal and partial stent fracture; C: OCT diagnosis of stent late malapposition; D: OCT diagnosis of in-stent neointimal hyperplasia and neoatherosclerosis. OCT: Optical coherence tomography.
