OBJECTIVES: This study aimed to evaluate the feasibility and underlying pharmacokinetics of the retrograde-outflow technique for percutaneous isolated hepatic perfusion (PIHP). METHODS: Retrograde-outflow PIHP was performed in 12 male @entity1707 (weight, 37-44  kg) by redirecting hepatic outflow through the portal vein. Blood with @entity900 (2.5  mg/kg) in an extracorporeal circuit was circulated through the liver under isolation using rotary pumps with balloon catheters. Hepatic angiographic examinations were conducted during perfusion, and histopathological examinations of the organs were conducted after perfusion. The maximum @entity902 concentration (C max), area under the concentration-time curve (AUC), and chronologic laboratory data were measured. RESULTS: Retrograde-outflow isolated hepatic angiography confirmed that contrast media flowed into the portal veins in all 12 @entity1707 . The hepatic veins and inferior vena cava were not opacified. Hepatic C max (86.3  mg/l) was 39-fold greater than systemic C max (2.2  mg/l), and hepatic AUC (1330.8  min        mg/l) was 30-fold greater than systemic AUC (44.6  min        mg/l). Histopathological examinations revealed no ischaemic changes or other @entity409 , duodenum, small intestine, or colon. Within 1  week of the procedure, chronologic laboratory data (n   =   3) normalized or returned to pre-therapy levels. CONCLUSIONS: The retrograde-outflow technique appears to enable safe and feasible PIHP therapy. KEY POINTS:     The portal vein acted as an outflow tract under retrograde-outflow PIHP.     Plasma hepatic-to-systemic exposure ratio was 39.2 for the maximum @entity902 concentration.     Plasma hepatic-to-systemic exposure ratio was 29.8 for the AUC.     The retrograde-outflow technique appears to enable safe and feasible PIHP.
