This study aimed to observe changes in the hydrogen sulfide (H2S) system in the blood and liver tissue of rats with hepatic cirrhosis at different stages by studying the effect of H2S on the course of hyperdynamic circulation in rats with hepatic cirrhosis. H2S concentration in the blood from the portal vein and inferior vena cava of hepatic cirrhosis rat model induced with carbon tetrachloride was detected on the 15th, 30th, and 52nd day. The expression of cystathionine β-synthase (CBS) and cystathionine γ-lyase (CSE) protein, and CBS and CSE mRNA in the liver was detected by immunohistochemistry and reverse transcriptase polymerase chain reaction (RT-PCR), respectively...

Renal carcinoma is an aggressive cancer with a high metastatic tendency. It may invade the renal vein, inferior vena cava and potentially extend in some cases to the right heart cavities. We report a case of a 71-year-old male presenting with an impressive polylobular tissular mass inside the right atrium and the right ventricle revealing an aggressive renal carcinoma extending through the inferior vena cava.

Aims: Chronic kidney disease (CKD) is a powerful independent risk factor for cardiovascular events, including vein graft failure. Because CKD impairs the clearance of small proteins, we tested the hypothesis that CKD exacerbates vein graft disease by elevating serum levels of critical cytokines that promote vein graft neointimal hyperplasia. Methods and results: We modelled CKD in C57BL/6 mice with 5/6ths nephrectomy, which reduced glomerular filtration rate by 60%, and we modelled vein grafting with inferior-vena-cava-to-carotid interposition grafting...

OBJECTIVE: To investigate the clinical usefulness of echocardiography in the diagnosis of infracardiac total anomalous pulmonary venous connection (ITAPVC) in neonates and infants. METHODS: Retrospective analysis on 8 patients with ITAPVC was performed using echocardiography between April 2006 and December 2016. There were 4 boys and 4 girls with a mean age of 79.8 days (ranging from 15 to 195 days). A combined scanning via parasternal, subcostal and apical acoustic windows had been employed to diagnose ITAPVC and to trace the course and site of the anomalous pulmonary venous drainage, and to confirm the direction of the inter-atrial shunt and enlargement of right atrium and right ventricle...

Anticoagulant therapy is commonly used for the prevention and treatment of patients with deep venous thrombus. Evidence has shown that rivaroxaban is a potential oral anticoagulant drug for the acute treatment of venous thromboembolism. However, the rivaroxaban-mediated molecular mechanism involved in the progression of deep venous thrombosis has not been investigated. In the present study, we investigated the efficacy of rivaroxaban and the underlying signaling pathways in the prevention and treatment of rats with deep venous thrombosis...

BACKGROUND: Patients with iliofemoral deep venous thrombosis are at risk for development of post-thrombotic syndrome. Iliac vein stenting has been shown to significantly improve clinical outcomes in patients with venous outflow obstruction, although many studies include a heterogeneous population with several different venous pathologic processes. Our objective was to evaluate the results of iliocaval and infrainguinal venous intervention for venous outflow obstruction due to post-thrombotic chronic venous occlusive disease...

BACKGROUND: Venous thromboembolism (VTE) is a feared complication after bariatric surgery. Biliopancreatic diversion with duodenal switch (BPD-DS) is a complex bariatric procedure that is offered typically to super morbidly obese patients. Scarce data exist in reporting VTE outcome and identifying the risk factors associated with it after BPD-DS. OBJECTIVE: To determine the risk factors for VTE after BPD-DS at 90-day follow-up. SETTING: A nonprofit regional referral center and teaching hospital in Pennsylvania...

Pulmonary embolism (PE) is a cause of significant morbidity and mortality, with an estimated 600,000 cases of clinically significant PE in the United States annually, and roughly 200,000 deaths per annum directly attributable to PE. By far the most frequent cause of PE is deep vein thrombosis originating in the lower extremities, which travels to the pulmonary vasculature. The mainstay of treatment is anticoagulation, but multiple additional treatments exist for patients in whom anticoagulation is inadequate or contraindicated...

The case of a 39-year-old highly sensitized woman who underwent second renal transplantation after being on warfarin because of a history of frequent thromboses of her left femoral arteriovenous graft (AVG) is reported here. The patient received a flow cytometric positive crossmatch kidney transplant from a deceased donor. Her posttransplant course was complicated by prolonged delayed graft function (DGF) lasting for 9 months. Antibody-mediated rejection occurred in the immediate postoperative period. This resolved after treatment, and resolution was confirmed by repeat biopsy...

BACKGROUND: In patients with polycystic liver disease, development of cysts induces hepatic venous outflow obstruction (HVOO) and parenchymal modifications, challenging the paradigm of a normal non-cystic liver parenchyma. The aims were to reappraise the pathology of the non-cystic parenchyma, by focusing on HVOO lesions; and to investigate the association with outflow obstruction at imaging and perioperative course after liver resection. METHODS: This is a retrospective study conducted in one tertiary center between 1993 and 2014...

Liver transplant is considered to be the last-resort treatment approach for pediatric patients with end-stage liver disease. Despite the remarkable advance in survival rates, liver transplant remains an intricate surgery with significant morbidity and mortality. Early diagnosis of complications is crucial for patient survival but is challenging given the lack of specificity in clinical presentation. Knowledge of the liver and vascular anatomy of the donor and the recipient or recipients before surgery is also important to avoid complications...

INTRODUCTION AND OBJECTIVE: We present our robotic approach and technique to manage a large left renal tumor with inferior vena cava (IVC) Level III thrombus. The superior mesenteric artery crossing the left renal vein requires robotic docking from the left, for dissection of the left kidney followed by repositioning and re-docking the robot from the right side for dissection of the right renal vein, distal and proximal IVC, and the remaining left renal vein insertion into the IVC. METHODS: We present a 53-year-old man with a 10...

Diabetes is a multifaceted disease with various etiologies. The complexity of this pathology creates a myriad of factors that must be considered when addressing surgical outcomes and prognosis. Of vital importance to cardiovascular surgery is the viability of homographic vein grafts. Due to the fact, diabetic patients have a higher rate of vein graph failure, a greater understanding of the effect diabetes has on vascular mechano-transductive response is critical to improving patient prognosis. This article represents data regarding a study published in Cardiovascular Diabetology (Rice et al...

OBJECTIVE: Fontan circulations have obligatory venous hypertension, depressed cardiac output and abnormal arterial elastance. Ventriculovascular coupling is known to be abnormal, but the underlying mechanisms are poorly defined. We aim to describe the histopathological features of vascular remodelling encountered in the central arteries and veins in the Fontan circulation as a possible underlying pathological representation of abnormal ventriculovascular coupling. METHODS: Postmortem vasculature (inferior vena cava (IVC), superior vena cava (SVC), pulmonary artery (PA), pulmonary vein (PV) and aorta) of 13 patients with a Fontan circulation (mean age 29...

Successful renal transplantation requires low-pressure venous drainage to permit adequate outflow from the allograft. We report here a series of three patients in whom the inferior vena cava as well as bilateral iliac veins were thrombosed, making it necessary to explore less traditional vessels for venous drainage of the renal allograft. We utilized the splanchnic vasculature in two cases, and the native left renal vein in another. The resulting atypical intra-abdominal locations of these allografts also presented difficulties for arterial anastomoses and for urinary drainage...
