Interventional radiology procedures in adult patients who underwent liver transplantation

Figure 2 Status post deceased donor LT. Doppler US performed 5 mo after the transplant showed low intrahepatic resistive index 0.50 and prolonged systolic acceleration time 0.113 s, suspected for HAS. A: MDCT volume rendering 3D reconstruction showed a severe stenosis in the hepatic artery anastomosis; B: Digital subtraction angiography (DSA) celiac arteriogram confirmed the stenosis, trans-stenotic pressure gradient measured by a microcatheter was 50 mmHg; C: DSA percutaneous transluminal angioplasty performed by 4 mm diameter balloon catheter; D: DSA final arteriogram showed good patency of the arterial anastomosis with trans-stenotic pressure gradient reduced to 4 mmHg. Doppler US performed 4 mo later showed regular resistive index 0.70 and systolic acceleration time 0.100 s. Patient currently in good general condition and without biliary tree impairment after 6 mo of follow-up.
