An analysis was made of the causes of death in 22 of 50 patients receiving consecutive orthotopic liver transplants. A close look at the fatal course of these patients revealed three major patterns: surgical complications (27%), pathology of the hepatic artery anastomosis (23%), and cholestasis (32%). Technical factors were the major reasons for excessive peroperative blood loss, and not the coagulopathy accompanying the liver disease. The etiology of hepatic artery thrombosis is not known. It leads to irreversible damage of the graft, causing death due to acute hepatic failure or to cholangitis and sepsis. The only way to treat patients with this complication is retransplantation. Several factors can induce cholestasis. Retrospectively, it appears that this was mostly due to inappropriate immunosuppression, often a result of the difficult differential diagnosis between rejection and viral infection. Recognition of these three basic patterns should enable us to anticipate their subsequent complications. This may lead to a reduction in morbidity and mortality after liver transplantation. 相似文献

Early complications after orthotopic liver transplantation 总被引:5,自引:0,他引:5
The cost and impact of early post-transplant complications continue to be high. Diagnosis and management involves a high index of suspicion, rapid diagnostic and therapeutic interventions, and elimination of technical problems. Preoperative assessment of the donor and recipient medical condition and meticulous attention to detail during the technical performance of OLTx are the mainstays in achieving a good outcome. 相似文献

We report venous complications, including portal vein and hepatic vein stenoses, that required interventional radiological treatment in three pediatric and two adult living related liver transplant recipients. Between April 2001 and April 2005, 81 liver transplantations were performed at our hospital. Sixty-two grafts were from living donors. During follow-up, three portal vein stenoses were identified in three pediatric recipients, and two hepatic vein stenoses in two adult patients. In the children, two had received left lateral segment grafts, and one had received a right lobe graft from two mothers and one father, respectively. The etiologies of liver failure were Alagille syndrome, biliary atresia, and fulminant Wilson's disease. Portal vein stenoses were identified at 8, 11, and 12 months after transplantation; all three patients underwent percutaneous transhepatic portal venous angioplasty with a success rate of 100%. The mean follow-up was 102 days; no recurrence has occurred. In contrast, hepatic venous stenoses were diagnosed in two adult recipients. One of them was a 24-year-old woman with autoimmune hepatitis and the other a 43-year-old man with cryptogenic cirrhosis. Hepatic vein stenoses were diagnosed at 3 and 4 months after transplantation. Both hepatic vein stenoses were dilated with balloon angioplasties via the transjugular route. Venous complications identified by Doppler ultrasonography were confirmed by computerized tomographic angiography. Angioplasty represents an effective and safe alternative to reconstructive surgery in the treatment of venous complications after liver transplantation. 相似文献

BACKGROUND: Mutism/speech apraxia has been well documented as a toxic effect of cyclosporine after liver transplantation but has been reported only rarely with tacrolimus. Brain imaging with magnetic resonance or computed tomography has failed to demonstrate abnormalities in affected patients. METHODS: We present the first example of an acute onset of loss of speech associated with a sudden elevation of serum tacrolimus level after successful orthotopic liver transplantation. We also describe the positron emission tomography (PET) scan of this patient's brain. RESULTS: PET scan imaging of the brain was abnormal, demonstrating decreased metabolism in the posterior temporo-parieto-occipital regions. Statistical probability mapping revealed additional areas of hypometabolism in the cingulate gyrus. CONCLUSIONS: PET scan revealed abnormalities of the brain in a patient with tacrolimus-induced mutism. The cingulate gyrus may play a role in the mutism/speech apraxia syndrome seen with cyclosporine/tacrolimus neurotoxicity. 相似文献

Complications involving the portal vein or the vena cava, are rare after orthotopic liver transplantation. We report on the incidence and treatment of venous complications following 1000 orthotopic liver transplantations in 911 patients. Twenty-six of the adult patients (2.7%) suffered from portal complications after transplantation, whereas complications of the vena cava were observed in only 17 patients (1.8%). Technical problems or recurrence of the underlying disease (e.g. Budd-Chiari syndrome) accounted for the majority of complications of the vena cava, whereas alteration of the vessel wall or splenectomy during transplantation could be identified as important risk factors for portal vein complications. In patients undergoing modification of the standard end-to-end veno-venous anastomosis of the portal vein due to pathological changes of the vessel wall, complications occurred in 8.3%, whereas only 2.4% of patients who received a standard anastomosis of the portal vein experienced complications of the portal vein. Furthermore, splenectomy during transplantation was also associated with an increased incidence of portal vein complications (10.5 vs. 2.2% in patients without splenectomy). Treatment was dependent on the signs and symptoms of the patients, and varied considerably between patients with portal vein complications and patients suffering from complications of the vena cava. Complications of the vena cava led to retransplantation in about one-third of the patients, whereas in patients with occlusion of the portal vein, retransplantation was necessary in only 15%, and more than half of the patients suffering from portal vein complications did not require any treatment at all. Usually, treatment of patients with portal vein complications only became necessary when additional complications such as arterial occlusion or bile duct injuries occurred. 相似文献

Over a 57-month period, we performed 430 orthotopic liver transplants in 372 patients. A total of 38 vascular complications were identified including hepatic artery thrombosis (n = 24), portal vein thrombosis (n = 6), combined hepatic artery thrombosis/portal vein thrombosis (n = 3), and hepatic artery rupture (n = 5). A number of potential risk factors for the development of vascular thrombosis were evaluated with only children, weight less than 10 kg, and cold ischemia time found to be significant. The clinical presentation included fulminant hepatic failure, allograft dysfunction, biliary sepsis, and screening ultrasound. Duplex ultrasonography was diagnostic in nearly all cases. Therapeutic modalities included revascularization, revascularization followed by retransplantation, retransplantation alone, and observation. Five cases of hepatic artery rupture occurred in four patients. Infectious arteritis was present in four patients. The 6-month actuarial survival in patients with vascular complications was 70%. Early diagnosis is critical for graft salvage, with surgical intervention the mainstay of therapy. 相似文献

Laparoscopic surgery is currently a widely accepted approach to several surgical fields because of its advantages in terms of postoperative pain reduction and easy patient recovery. This approach may be useful even in solid-organ transplantation surgery as a diagnostic or treatment procedure in some surgical complications. From July 1991 to December 1998, we performed 142 liver transplantations on 129 patients. During the postoperative period, many complications occurred. Here we report two cases of intestinal occlusion caused by adhesions and three cases of lymphocele, all approached with laparoscopic surgery. In all cases but one, we were able to complete the surgery by laparoscopic means; in one of the two occlusions, the procedure was switched to laparotomy because of a choledochojejunal anastomosis lesion. The three cases of lymphocele must be considered in a particular manner because such cases, to our knowledge, have never been described in the literature. They always presented with a late-onset right pleural effusion and were located in the retrohepatic, retrogastric, and left paracaval areas, close to the esophageal hiatus. In conclusion, we believe a laparoscopic approach is a useful strategy to solve some surgical complications in patients who underwent orthotopic liver transplantation; however, the use of laparoscopic surgery in this field is strictly connected to the surgeon's experience and versatility. 相似文献

目的分析原位肝移植术后早期肝功能不全(early allograft dysfunction,EAD)的发生情况,并探讨EAD发生的相关危险因素。方法回顾性分析武汉大学人民医院2016年1月至2020年12月实施的74例原位肝移植病人的临床资料,对可能导致术后EAD的围手术期相关因素进行单因素分析,然后将有显著性差异的因素纳入Logistic回归多因素分析。结果74例肝移植病人术后EAD的发生率为36.5%(27/74)。单因素分析结果显示,受者术前中性粒细胞与淋巴细胞比值(NLR)、术前血清总胆红素、术中失血量、术前肝功能Child-Pugh分级C级、术前终末期肝病模型(MELD)评分≥18分及术后出现胆道及血管并发症是EAD发生的潜在危险因素(均P<0.05);多因素Logistic回归分析结果显示,肝移植术后EAD的独立危险因素为:术前MELD评分≥18分[OR=0.045,95%CI(0.003,0.605),P=0.045];移植术后出现胆道及血管并发症[OR=0.061,95%CI(0.009.0.419),P=0.004]。结论术前MELD评分≥18分及术后出现胆道及血管并发症是影响肝移植术后EAD的独立危险因素。临床上应该通过改善受者术前较差的肝功能和提高临床医师手术技巧来降低EAD的发生率。 相似文献

Alteration of speech is a rare but distressing complication of orthotopic liver transplantation (OLT). We describe a characteristic speech disorder identified in a large series of consecutive patients undergoing OLT. Between 1988 and 1993, 525 adults underwent OLT. For all recipients with neurologic complications, we reviewed clinical findings, imaging and electrophysiologic test results, and perioperative laboratory data. Five patients (ages 23–52; UNOS status 3–4) exhibited a characteristic pattern of stuttering dysarthria, leading to complete loss of speech production, occasionally with elements of aphasia. In four of the five patients, right-sided focal seizures were subsequently noted. All cases presented within the first 10 postoperative days and improved within 1 month of cessation of cyclosporin (CyA), although halting, monotonous speech was evident to some degree in all five for up to 1 year. There was no correlation between onset of symptoms and CyA levels. None of the patients had clinical or radiologic findings suggestive of central pontine myelinolysis or akinetic mutism. EEGs and Spect scan results were consistent with dysfunction in the left frontotemporoparietal regions of the brain. A characteristic speech disorder, which may be described as cortical dysarthria or speech apraxia, occurs in approximately 1% of adults undergoing OLT. Prompt recognition of this syndrome and temporary cessation of CyA therapy may favorably affect the course. 相似文献

Intrahepatic biliary lesions (IBL) are rare (2–9 %) after orthotopic liver transplantation (OLT). The aim was to evaluate
the incidence, etiology and outcome. In nine years, a total 532 OLTs were performed in 481 patients. Twenty-four patients
developed IBL. Eight were due to HAT, seven to ABOI, three to CDR and six to PI. The time until diagnosis of HAT is longest
in patients (14 ± 6) with IBL. ABOI is another cause of IBL. CDR is a rare cause of IBL, however when it takes place, patients
must undergo Rtx. Finally, PI is a relevant cause of IBL. In order to suppress the incidence of IBL we should consider 1)
the systematic use of Doppler-Ultrasound; 2) emergency reoperation of patients with HAT, 3) avoid ABOI in OLT; 4) Rtx in cases
of CDR, and 5) OLT should still be performed as an emergency procedure.

Bowel perforation is a well-recognized complication following orthotopic liver transplantation. Of 194 paediatric liver transplantations
performed in our hospital, 13 patients (6.7 %) developed bowel perforation post-transplantation. Contributory factors included
previous operation, steroid therapy and viral infection. The incidence was higher in children who underwent transplantation
for biliary atresia after a previous Kasai portoenterostomy. Seven patients (53 % of this group) reperforated. Diagnosis may
be difficult and a high index of suspicion is needed.

BACKGROUND: Pediatric orthotopic liver transplantation (OLT) has a low mortality. Some children, however, have an adverse outcome defined as a prolonged ventilatory support requirement and protracted pediatric intensive care unit (PICU) stay. The aim of this study was to determine if that adverse outcome related to the child's condition pre-OLT and/or the development of a pleural effusion or diaphragmatic dysfunction. METHODS: The study included 210 children with a median age at transplantation of 45.5 months (range 0.2-252 months). Fourteen had undergone retransplantation. The duration of ventilatory support (intermittent positive pressure ventilation [IPPV]) and PICU admission and development of a pleural effusion and/or diaphragmatic dysfunction were documented for each child. The patients were divided into three groups according to whether they had acute liver failure (ALF), chronic liver disease at home (CHOM), or chronic liver failure sufficiently ill to be in the hospital awaiting transplantation (CHOSP). RESULTS: The 36 children with ALF were of similar age to the 138 CHOM and 36 CHOSP children but required longer IPPV (P<0.0001) and PICU stay (P<0.0001). Overall, 17 children developed diaphragmatic dysfunction and 138 pleural effusions; affected children required longer IPPV and PICU stay (P<0.01). Regression analysis demonstrated that diaphragmatic dysfunction, but not pleural effusion development, was associated with prolonged ventilation (P<0.01) and protracted PICU stay (P<0.05). Other risk factors were ALF (P<0.01), retransplantation (P<0.01), and young age (P<0.05). CONCLUSION: Diaphragmatic dysfunction adversely influences PICU morbidity after OLT. Early assessment of diaphragmatic function, and if necessary aggressive management, might improve outcome. 相似文献
