A case of spontaneously ruptured hepatic angiosarcoma resected after transcatheter arterial embolization.

Hepatic angiosarcoma is a very rare disease, but it has a poor prognosis. Here, we report the case of a 77-year-old man who was referred to our hospital for suspicion of hepatocellular carcinoma and cancerous peritonitis. Based on the imaging findings, a diagnosis of spontaneously ruptured hepatic hemangioma was made.

Usefulness of Preoperative Controlling Nutritional Status in Predicting Prolonged Hospitalization and Incidence of Postoperative Delirium for Elderly Hepatectomy with Hepatocellular Carcinoma.

The number of elderly patients with hepatocellular carcinoma (HCC) has been increasing, but it remains unclear whether hepatectomy can be performed using the same criteria as in younger patients. Furthermore, the appropriate preoperative evaluation for hepatectomy in elderly patients is not yet clearly defined. Here, we investigated the applicability of preoperative assessment using the Controlling Nutritional Status (CONUT) score to help improve hepatectomy outcomes in elderly patients with HCC.

Recurrence of Adult Granulosa Cell Tumor in the Greater Omentum 11 Years after Surgery.

Adult-type ovarian granulosa cell tumors (AGCTs) are very rare tumors that account for <5% of all ovarian carcinomas. AGCTs have low malignancy potential and rarely metastasize 5-30 years after the initial diagnosis. Because time has passed from the first surgery and because recurrence develops in various locations, the differential diagnosis is difficult.

[A case of inflammatory cerebral amyloid angiopathy with white matter lesions appearing after brain biopsy].

A 76-year-old woman with a 7-year history of dementia presented to our hospital with generalized convulsive seizure for the first time. Contrast-enhanced brain magnetic resonance imaging revealed leptomeningeal enhancement mainly in the right occipital lobe and multiple lobar microbleeds in the bilateral cerebral and cerebellar subcortex. No white matter lesions were observed.

Possible Cerebral Vasculitis in a Case with Rheumatoid Arthritis.

Cerebral rheumatoid vasculitis (CRV) is a rare, fatal, and diagnostically challenging disorder. We herein report an 81-year-old woman with a 4-year history of rheumatoid arthritis who presented with a fever, progressive disturbance of consciousness, high level of rheumatoid factor, and hypocomplementemia. The enhancement of the perforating branches in the left middle cerebral artery led us to suspect CRV.

[A case of cerebral venous sinus thrombosis mimicking transient ischemic attack].

A 48-year-old woman with a right-sided headache beginning a month prior to admission presented with sudden-onset right hemiparesis. On admission, she had weakness of the right lower extremity, which disappeared 3 hours after onset. Contrast enhanced brain MRI revealed no parenchymal lesion, while indicated thrombi in the superior sagittal sinus and the right side of the transverse sinus, sigmoid sinus, and internal jugular vein, leading to the diagnosis of cerebral venous sinus thrombosis.

Trousseau syndrome with intrahepatic cholangiocarcinoma that could be removed radically after endovascular treatment: Report of a case.

Background: Trousseau syndrome is a poor prognosis. We report a case of Trousseau syndrome treated by radical resection after endovascular treatment.

Case: A 59-year-old woman presented to our department reporting spontaneous dizziness and pain of the upper abdomen.

Effects of Short-Term Normothermic and Subnormothermic Perfusion After Cold Preservation on Liver Transplantation From Donors After Cardiac Death.

Background: Liver transplantation from donors after cardiac death (DCD) could increase the pool of organs. We previously reported that oxygenated subnormothermic (20°C-25°C) ex vivo liver perfusion (SELP) improved the graft viability in rats. This study aimed to compare the effectiveness of SELP and normothermic (37°C) ex vivo liver perfusion (NELP) after cold storage (CS) in DCD liver grafts.

Intraoperative modulation of arterial blood flow in a hybrid operating room: A report of three cases.

The preoperative modulation of arterial blood flow is widely performed to prevent massive intraoperative hemorrhage and unstable circulatory dynamics; however, this may cause complications. The intraoperative modulation of arterial blood flow can be performed with operation to reduce the physical and psychological stresses on the patients and improve intraoperative safety.

Association of post-transplant donor-specific HLA antibody with liver graft fibrosis during long-term follow-up after pediatric liver transplantation.

The aim of this study was to evaluate the significance of post-transplant DSA as a predictor of liver fibrosis during long-term follow-up after pediatric LT. We evaluated the histological findings in 18 LT recipients who underwent liver biopsy after DSA screening. Liver fibrosis was scored based on the METAVIR fibrosis staging.

The Effects of Short-term Subnormothermic Perfusion After Cold Preservation on Liver Grafts From Donors After Circulatory Death: An Ex Vivo Rat Model.

Background: We previously reported that short oxygenated warm perfusion before cold storage (CS) had improved the graft viability of rat livers from donors after circulatory death (DCD). In this study, we investigated the effectiveness of short-term oxygenated subnormothermic perfusion for different durations after CS in a rat DCD model.

Methods: We used an isolated perfused rat liver system.

The extra-anatomical jump graft reconstruction of the right hepatic artery after resection of a biliary tract malignancy with a common hepatic artery aneurysm: a case report.

Performing resection of a biliary tract malignancy with a hepatic artery aneurysm is very challenging. Resection of the extrahepatic bile duct and extra-anatomical reconstruction can be successfully performed using free radial artery autografts from the aorta to the right hepatic artery. Hepatic artery thrombosis can be prevented with intimal preservation.

Renoportal Anastomosis in Left Lateral Lobe Living Donor Liver Transplantation: A Pediatric Case.

In adult liver transplantation, renoportal anastomosis (RPA) has been introduced as a useful technique for patients with grade 4 portal vein thrombosis and a splenorenal shunt. Here, we report a pediatric case in which RPA allowed a left lateral lobe living donor liver transplantation (LDLT) despite portal vein thrombosis and a large splenorenal shunt. At 36 days old, the patient underwent a Kasai operation for biliary atresia.

Impact of the Trough Level of Calcineurin Inhibitor on the Prevalence of Donor-Specific Human Leukocyte Antigen Antibodies During Long-Term Follow-Up After Pediatric Liver Transplantation: Antibody Strength and Complement-Binding Ability.

Background: In pediatric patients, long-term immunosuppression after liver transplantation (LT) is typically minimal. However, posttransplant donor-specific HLA antibodies (DSAs) may be prevalent under these conditions. Here, we evaluated the effects of minimized calcineurin inhibitor (CNI) on DSA development to assess the validity of minimized/withdrawn immunosuppression.

The utility of superb microvascular imaging for monitoring low-velocity venous flow following pancreas transplantation: report of a case.

Vascular thrombosis is a major complication after pancreas transplantation. Because delays in detecting thrombosis often result in graft failure, monitoring blood flow is crucial. Periodic evaluation using color Doppler ultrasonography is mostly performed for monitoring blood flow in the grafted pancreas.

Effect of Recipient Age at Liver Transplantation on Prevalence of Post-Transplant Donor-Specific HLA Antibody.

BACKGROUND Post-transplant donor-specific HLA antibodies (DSA) may have a detrimental effect on long-term outcomes of organ transplantation. The aim of this study was to specifically evaluate the effect of recipient age on the prevalence of DSA over a long-term follow-up after living donor liver transplantation (LDLT). MATERIAL AND METHODS A retrospective analysis of DSA evaluations was performed in 50 pediatric patients with HLA data available.

Arterial and biliary complications after living donor liver transplantation: a single-center retrospective study and literature review.

Aim: The mortality of patients on the waiting list for deceased donor liver transplantation (DDLT) is high, especially in countries where donation rates are low. Thus, living donor liver transplantation (LDLT) is an attractive option. However, compared with DDLT, LDLT is associated with increased rates of arterial and biliary complications.

Hassab's operation for Joubert syndrome with congenital hepatic fibrosis: A case report.

Introduction: Joubert syndrome is characterized by psychomotor developmental delay, hypotonia, oculomotor abnormalities, occasional retinal dystrophy and cystic kidneys, and frequent and often, striking breathing abnormalities, especially in the neonatal period, with panting tachypnea followed by apnea. We report a case of Joubert syndrome with hepatic fibrosis, portal hypertension, and pancytopenia treated by Hassab's operation.

Presentation Of Case: Our patient was a 27-year-old woman with a history of tachypnea, muscle hypotonia, and psychomotor retardation shortly after birth and a diagnosis of Joubert syndrome at 2 years of age.

Extrahepatic bile duct hepatocellular carcinoma due to recurrence of hematogenous metastasis 50 months after hepatectomy.

Background: Recurrent hepatocellular carcinoma (HCC) in the extrahepatic bile duct is rare with most cases diagnosed after manifesting sudden obstructive jaundice. Here, we report an extremely rare case of recurrent HCC in the common bile duct due to hematogenous metastasis.

Case Presentation: A 66-year-old man underwent an extended left hepatectomy for HCC in the medial segment of the liver.

Spontaneous resolution of de novo hepatitis B after living donor liver transplantation with hepatitis B core antibody positive graft: a case report.

Background: Hepatitis B core antibody (HBcAb)-positive graft is reported to cause de novo hepatitis B after liver transplantation with a probability of 38-100 % without prophylaxis. Hepatitis B surface antigen loss is reported to be achieved with a probability of only 3-8 % in the patients treated by antiviral agents. We present an extremely rare case of spontaneous resolution of de novo hepatitis B after living donor liver transplantation (LDLT) with HBcAb-positive graft.

Surgical resection of recurrent extrahepatic hepatocellular carcinoma with tumor thrombus extending into the right atrium under cardiopulmonary bypass: a case report and review of the literature.

Background: Recurrent hepatocellular carcinoma accompanied by a right atrial tumor thrombus is rare. No standard treatment modality has been established. Surgical treatment may be the only curative treatment; however, surgery has been considered high risk.

Soluble Thrombomodulin Ameliorates Ischemia-Reperfusion Injury of Liver Grafts by Modulating the Proinflammatory Role of High-Mobility Group Box 1.

Transplantation using grafts obtained after cardiac death (CD) is considered a promising solution for graft shortages. However, no standard criteria for organ preservation have been established for CD donors. High-mobility group box 1 (HMGB1) is a DNA-binding protein that is released from dying hepatocytes as an early mediator of inflammation and organ tissue damage.

Risk factors for recurrence in stage II/III colorectal cancer patients treated with curative surgery: The impact of postoperative tumor markers and an infiltrative growth pattern.

Background And Objectives: We evaluated the capacity of clinicopathological factors to predict recurrence in stage II/III colorectal cancer (CRC) patients after curative resection.

Methods: We retrospectively examined 386 stage II/III CRC patients who underwent curative resections between April 2008 and August 2013. We assessed the predictive power of pre- and postoperative tumor marker levels, lymphatic and venous invasion, and infiltrative growth patterns using Cox's proportional hazards model.

Short Oxygenated Warm Perfusion With Prostaglandin E1 Administration Before Cold Preservation as a Novel Resuscitation Method for Liver Grafts From Donors After Cardiac Death in a Rat In Vivo Model.

Background: We previously demonstrated that short oxygenated warm perfusion (SOWP) prevented warm ischemia-reperfusion injury in rat livers from donors after cardiac death (DCDs) in an ex vivo model. In the present study, we aimed to examine the in vivo effects of SOWP and SOWP with prostaglandin E1 (PGE1) in DCD rat liver transplants.

Methods: We performed liver transplantation after 6-hour cold preservation using grafts retrieved from DCD rats, divided into nontreatment (NT), SOWP, and SOWP with PGE1 (SOWP + PG) treatment groups.
