Clinical and imaging study on hepatic venous congestion of Ⅴ, Ⅷ segments in living donor liver transplantation / 中华普通外科杂志

ABSTRACT

Objective To evaluate MSCT appearance and impaction of Ⅴ, Ⅷ segments' hepatic venous congestion ( HVC ) on hepatic functional recovery in living donor liver transplantation (LDLT).Methods In this study, 83 patients undergoing LDLT in our hospital were included, all subjects received plain and contrast MSCT examinations at early stage (within 1 month) and later stage (3 months later) after LDLT. MSCT appearance of HVC was recorded, at the same time, gutamic pyruvic transaminase ( ALT),glutamic oxalacetic transaminase (AST), total bilirubin (TB) and prothrombin time (PT) of 1 to 7 days after LDLT between congestion group and non-congestion group were recorded and compared.Results Segments Ⅴ and Ⅷ congestion was identified by after LDLT CT scanning in 20 patients (24. 10% ). Congestion volume and congestion ratio was (218. 25 ± 130. 29) cm3 and 16. 68% ±8. 81%,respectively. HVC often appear as hypoattenuation on plain CT scan and arterial phase, mixed or hyperattenuation on portal vein phase. There was no significant difference of ALT, AST, TB and PT after LDLT between congestion group and non-congestion group (P ＞ 0. 05). Conclusions MSCT is a valuable method to evaluate Ⅴ, Ⅷ segments' HVC after LDLT, most HVC has no impaction on hepatic functional recovery in LDLT patients.
