探讨肝移植术后淋巴组织增生性疾病(posttransplant lymphoproliferative disease,PTLD)的诊断和治疗.方法 回顾性分析1例肝移植后PTLD的临床表现、诊断和治疗过程,并复习相关文献.结果 2003年10月至2011年12月在中山大学附属第三医院肝移植中心随访的336例肝移植术后患者中有1例发生PTLD,发生率为0.3%.该例患者的临床表现不典型,主要表现为反复发热、腹部不适、多处淋巴结肿大和肝脏占位病变等,淋巴结活组织检查提示B细胞源性非霍奇金淋巴瘤淋巴瘤,确诊为PTLD.经减少免疫抑制剂用量、抗炎,对症支持治疗无效后死亡.结论 肝移植术后PTLD的临床表现不典型,易被误诊或延误诊断,预后甚差.治疗以减少免疫抑制剂用量、抑制淋巴细胞增殖、对症支持治疗为主. 相似文献

目的观察肝窦阻塞综合征(HSOS)的CT和MRI表现。方法回顾性分析45例经临床或肝穿刺活检证实的HSOS患者的临床及影像学资料。结果41例患者接受CT检查,平扫显示20例肝脏增大,7例肝左叶及尾状叶增大,21例肝实质密度不均匀性减低,36例出现不同程度腹腔积液、2例胸腔积液;增强扫描31例肝实质不均匀强化,21例呈“地图状”强化,9例斑片状不均匀强化,1例轻微小片强化;门静脉期均表现为斑片状、“地图状”强化,延迟期强化范围进一步扩大;均未见胆管扩张及肝内外侧支血管形成。12例接受MRI检查,平扫均表现为肝内信号欠均匀,10例肝脏增大,5例下腔静脉肝后段受压变细,胆囊形态均正常;增强后肝实质强化不均,表现为片状强化减低区及异常强化灶,呈“地图状”。结论HSOS的CT和MRI表现具有一定特征性,有助于临床诊断。 相似文献

We analyzed the features of 7 patients who underwent orthotopic liver transplantation (OLT) from April 2001 to April 2006 for incurable hepatic alveolar echinococcosis (AE) in view of the technical features of the OLT, incidence, and type of complications, as well as patient survival. All 7 patients had biliary diseases that resulted from parasitic involvement of the hilum or a large parasitic lesion that invaded the lobes of the liver due to parasitic involvement of the hepatic veins, which are all typical syndromes of hepatic AE. Five patients had previously undergone surgery for hepatic AE and were at the end stage of liver functional disorder. Four patients' operations were performed under venovenous bypass. The mean duration of surgery was 9.1 hours. After transplantation, one patient experienced biliary leakage but was successfully treated with reoperation. One patient died 21 days later of septicemia caused by pneumonia and multiple organ failure, and another patient died 3 months after OLT from heart failure. The other 5 patients are alive and in good condition after transplantation. Although the transplantation procedure was more difficult than usual in these patients, most achieved prolonged survival and a good quality of life. This study suggests that OLT is feasible for incurable AE of the liver and that this procedure ensures a good clinical outcome. 相似文献

分析肝移植术后患者发生噬血细胞综合征(hemophagocytic syndrome,HPS)的危险因素及其临床特点、诊断和预后.方法 回顾性分析中山大学附属第三医院肝移植中心772例肝移植受者中发生的l例HPS患者的临床资料,并结合已经报道的13例肝移植术后HPS的临床资料进行文献复习.结果 患者,男性、45岁,在肝移植术后36 d发生持续性高热、全血细胞减少、凝血功能障碍和血清铁蛋白的水平升高.根据临床表现、实验室检查和骨髓活组织检查结果诊断为HPS.给予积极的肾上腺皮质激素冲击、注射粒细胞集落刺激因子和大剂量的免疫球蛋白治疗,因病情凶险,患者于术后54 d死于颅内出血和多器官功能衰竭.在14例肝移植术后HPS患者中,临床表现为发热(14/14)、脾肿大(8/14);实验室检查发现贫血、血小板减少、白细胞减少、肝脏转氨酶升高(9/14);71%的患者血清铁蛋白水平升高.HPS的发生与病毒感染(8/14)有关.尽管给予积极的抗感染治疗和免疫抑制剂的减量,但仍有9例患者在术后2个月内死亡.结论 肝移植术后HPS的发生与病毒尤其是爱泼斯坦-巴尔病毒(Epstein-Barruirus,EBV)和巨细胞病毒(CMV)感染有关.临床上疑似HPS时,应反复进行骨髓涂片检查,有助于早期确诊.尽管早期积极的合理治疗能够一定程度上控制病情,但总体预后极差. 相似文献

目的 探讨三次肝移植的临床疗效.方法 回顾性分析2002年4月至2012年12月武警总医院收治的4例肝胆疾病患者的临床资料.供肝植入均采用经典原位肝移植.术后均采用他克莫司+吗替麦考酚酯+激素3联免疫抑制方案.通过移植随访中心随访至2014年5月,了解患者预后并进行用药指导.计量资料采用t检验.结果 4例患者中,3例良性肝脏疾病患者多次行肝移植原因主要为胆道并发症,其次为慢性排斥反应;1例肝癌患者多次肝移植原因主要为肝癌复发.4例患者第1、2次肝移植中位间隔时间为16.0个月,短于第2、3次肝移植的22.5个月.第2次肝移植手术时间为(11.4±1.0)h,第3次肝移植手术时间为(14.1±2.2)h,第2、3次肝移植手术时间比较,差异有统计学意义(t=3.644,P<0.05).第2、3次肝移植中位出血量分别为1 300 mL和1 800 mL,中位输血量分别为1 400mL和3 100 mL.4例患者肝移植术后早期肝功能均恢复顺利.4例患者中,有2例3例次[其中1次为术后早期(<30 d)出现肺部铜绿假单胞菌感染]发生移植后感染,后经过积极抗感染治疗后痊愈.4例患者中,1例于第1次肝移植术后80个月死于肝衰竭;1例于第1次肝移植术后107个月死于肝癌复发合并肺、骨及腹膜后淋巴结等多处转移;另2例于第1次肝移植术后分别生存104个月和26个月.结论 三次肝移植是治疗移植肝胆道并发症及慢性排斥反应的有效方法;如有条件,三次肝移植对肝癌复发患者也能明显延长其生存时间. 相似文献

Liver involvement in patients with hereditary hemorrhagic telangiectasia (HHT) has not been fully characterized in China. The clinical manifestations, imaging studies, results of treatment in six patients and symptomatic liver involvement were analyzed. Patients included three women and three men with age from 35 to 62 years old. Two patients presented with shortness of breath, one patient with anemia and splenomegaly, and one with chronic gastrointestinal bleeding; the remaining two were asymptomatic. CT and CT angiography (CTA) showed arterioportal and arteriovenous shunting in liver. CTA showed at least one enlarged hepatic artery in all patients. One patient received ligation of the enlarged arteries with subsequent disappearance of symptoms at 56-month follow-up. The patient with gastrointestinal bleeding received interventional embolotherapy and resolved; interventional therapy to embolize the enlarged hepatic arteries was unsuccessful in another patient and the patient died of heart failure and liver dysfunction 38 months later. The patient with splenomegaly received a splenectomy and bandage of an enlarged hepatic artery. One of the two patients with no symptoms died of liver dysfunction 41 months after diagnosis. The other showed abnormal liver function and ascites, and traditional Chinese medicinal herb was used with no effect 21 months later. The symptoms disappeared after systemic medical treatment. Individualized and active therapy is advantageous and proper for patients with HHT. 相似文献

目的探讨儿童劈离式肝移植术后肝静脉流出道梗阻(hapatic venous outflow obstruction,HVOO)的病因、临床表现、诊断及治疗。方法回顾性分析1例儿童劈离式肝移植术后肝静脉流出道梗阻病例的临床资料并进行文献复习。结果患儿于术后8个月无明显诱因出现腹胀、纳差、双下肢水肿,经腹部B超、计算机断层摄影术(computed tomography,CT)增强扫描、下腔静脉及肝静脉造影确诊迟发型HVOO,遂行球囊扩张术,手术成功。球囊扩张术后10个月及15个月HVOO复发,均接受再次球囊扩张术,手术成功。随访至今患儿存活,未再发腹胀、纳差,肝功能正常。结论对于术后无明显诱因出现腹水、腹胀、纳差和双下肢水肿等表现的患儿,应重点排除HVOO,下腔静脉及肝静脉造影是诊断该病的金标准。对于迟发型的HVOO患儿,球囊扩张术和支架置入是理想的治疗方式,但支架置入的选择及时机仍存在争议。 相似文献
