We present a 12‐month‐old female who received an uneventful LDLT from her mother, and the GRWR was 4.8. During the early post‐operative period, she became hemodynamically unstable, developed ascites, and altered LFT. The post‐operative ultrasound identified reversed portal flow, finding a non‐anatomical PSS. A 3D CT scan confirmed the presence of a mesocaval shunt through the territory of the right gonadal vein, draining into the right iliac vein, with no portal inflow into the liver. The patient was re‐operated, and the shunt was ligated. An intraoperative Doppler ultrasound showed adequate portal inflow after...

METHODS: A longitudinal cohort study was conducted by 14 regional hospitals starting in 2009 through 2016. All adult patients with newly diagnosed HCC either with pathology or imaging criteria were included. Patients were classified ...

AbstractLivers removed during transplant hepatectomies could represent a useful anatomic ex vivo resource for surgical training, since they are intact and not altered by post-mortem changes yet. The aim of this study is to investigate the effectiveness of such kind of surgical training applied on some hepatic surgery techniques. In the present paper, we focused on split liver operation and middle hepatic vein (MHV) bipartition/reconstruction, since these procedures have a quite long learning curve. Seven native livers were submitted to split liver procedure by a senior resident assisted by a fully trained hepatic surgeon. ...

ConclusionsMass-forming extramedullary hematopoiesis is rare; however, our report emphasizes that it needs to be considered in the initial differential diagnosis of hepatic lesions arising in the setting of bone marrow disorders. We also show that in the setting of diffuse hepatic iron overload, tumefactive extramedullary hematopoiesis appeared isointense to background liver on T2* gradient-echo sequence, while adenoma, hepatoma, and hepatic metastasis appear hyperintense. Thus, T2*-weighted gradient-echo sequence may have a potential role in the imaging diagnosis of mass-forming hepatic extramedullary hematopoiesis arisin...

Publication date: Available online 5 January 2018 Source:The Lancet Author(s): Alejandro Forner, María Reig, Jordi Bruix Hepatocellular carcinoma appears frequently in patients with cirrhosis. Surveillance by biannual ultrasound is recommended for such patients because it allows diagnosis at an early stage, when effective therapies are feasible. The best candidates for resection are patients with a solitary tumour and preserved liver function. Liver transplantation benefits patients who are not good candidates for surgical resection, and the best candidates are those within Milan criteria (solitary tumour ≤5 cm ...

We present an exceptional case where NIPT contradicts the ultrasound‐based sex determination. The pregnant woman was recipient of a liver transplant from a male donor. Graft‐derived cell‐free DNA released into the maternal circulation clouded the NIPT‐based sex determination. Hence, NIPT is not advisable when the pregnant mother underwent an organ transplant.

There are no clear recommendations regarding cirrhotic cardiomyopathy (CC) evaluation in patients with pre-transplant liver cirrhosis. The roles of new methods, tissue Doppler imaging (TDI) and speckle tracking echocardiography (STE) in the diagnosis and prognosis of cirrhotic cardiomyopathy remain controversial. We investigated the utility of TDI/STE parameters in cirrhotic cardiomyopathy diagnosis and also in predicting mortality in patients with liver cirrhosis. Left/right ventricular function was studied using conventional TDI (velocities) and STE (strain/strain rate).

e H Abstract In 2015, more than 13 000 people died due to the consequences of liver cirrhosis in Germany. Frequently, relevant liver fibrosis is diagnosed by non-invasive methods (e. g., ultrasound-based measurement of liver stiffness) already in the compensated stage. Following diagnosis of liver fibrosis, a thorough investigation of the underlying chronic liver disease and effective treatment are important to prevent progression to decompensated cirrhosis. Since morbidity and mortality dramatically increase in the decompensated stage (patients may present with jaundice, ascites, hepatic encephalopathy, gastr...

CONCLUSION: The prevalence of PCNs in LT recipients was similar to the general population (3.6%, 31/872). Side-branch IPMNs do not appear to have accelerated malignant potential in post-LT patients, indicating the current surveillance guidelines are applicable to this group.

AbstractA spectrum of vascular complications can be seen in pediatric liver transplant patients, including occlusion and hemodynamically significant narrowing of the vessels that provide inflow to or outflow from the graft. Intraoperative Doppler ultrasound (US) has the potential benefit of identifying vascular complications in pediatric liver transplant patients prior to abdominal closure. Importantly, intraoperative Doppler US can be used as a problem-solving tool in situations such as position-dependent kinking of the portal or hepatic veins, or in suspected vasospasm of the hepatic artery. Furthermore, this technique c...
