活体肝移植术后Ⅴ、Ⅷ段肝静脉淤血的临床及影像学观察

Clinical and imaging study on hepatic venous congestion of V, VIII segments in living donor liver transplantation

目的 评价活体肝移植（living donorlivertransplantation,LDLT）术后Ⅴ、Ⅷ段肝静脉淤血（hepatic venous congestion,HVC）的MSCT表现及其对患者术后肝功能恢复的影响.方法83例在天津市第一中心医院移植外科施行活体右半肝移植的患者纳入本研究,所有患者均于术后早期（≤1个月）和术后中晚期（≥3个月）进行MSCT平扫和增强检查,记录淤血区的MSCT表现和患者术后1～7 d丙氨酸转氨酶（ALT）、天冬氨酸转氨酶（AST）、总胆红素（TB）及凝血酶原时间（PT）.比较淤血组和无淤血组上述指标之间的差异.结果 20例患者（24.10%）LDLT术后1个月内出现Ⅴ、Ⅷ段HVC,淤血区体积和淤血率分别为（218.25±130.29）cm3和16.68%±8.81%.淤血区于MSCT平扫及动脉期多呈低密度,门静脉期多呈混杂密度或高密度,增强后动脉期及门静脉期呈持续低密度者预后不良.淤血组与无淤血组患者术后1～7 d各项肝功能化验指标差异均无统计学意义（均P＞0.05）.结论 MSCT是评价LDLT术后Ⅴ、Ⅷ段HVC的有效方法,多数HVC对LDLT术后患者肝功能恢复没有影响.

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.
