Article Abstract
A 13-year-old boy born with hypoplastic left heart syndrome, who underwent all three stages of univentricular palliation and multiple interstage operations, developed failing Fontan circulation with protein-losing enteropathy and massive pleural and peritoneal effusions. In this video tutorial, surgical assessment and implanting an isolated subpulmonary ventricular assist device for support using the EXCOR Venous Cannula and a 30-cc EXCOR system are described. In addition, aspects of the surgical removal of "fenestration" devices are reported. Cardiopulmonary bypass is established in a central fashion, and the procedure is conducted under mild hypothermia and partially induced ventricular fibrillation. The superior vena cava and an 18-mm extracardiac Fontan conduit are completely divided. The fenestration devices are partially removed through the opening in the right pulmonary artery. The EXCOR venous inlet cannula is first anastomosed to a rim of the Fontan graft connected to the inferior vena cava. Then it is anastomosed to the superior vena cava by means of an interposition graft. The final anastomosis connects the outflow cannula to the superior part of the former Fontan conduit.

Management of renal cancer with inferior vena cava extension over 30 years: a bi-centric study.
World J Urol

Department of Urology and Transplantation Surgery, Nantes University Hospital, Nantes, France.
Purpose: In 5-10% of cases, renal cancer extends into the venous system, particularly the inferior vena cava (IVC), which worsens prognosis. This study aims to assess morbidity, mortality, and oncological outcomes of patients treated surgically for renal cancer with IVC extension over a 30-year period, in two experienced centers.
Materials And Methods: This bicentric, retrospective study analyzed patients treated between 1988 and 2020 for renal cancer involving the IVC.

Autologous Graft for Venous Vascular Reconstruction in Hepatopancreatobiliary Surgery: A Single Center Experience.

Department of Hepatobiliary-Pancreatic Surgery, Juntendo University School of Medicine, Tokyo, Japan.
Background: Achieving R0 resection in hepatopancreatobiliary (HBP) surgery frequently necessitates venous resection and reconstruction. Autologous grafts offer a promising solution, particularly in complex resections where infection risk or graft availability limit the use of synthetic or donor grafts. However, clinical data on the outcomes of autologous venous grafts remain limited.

Objectives: To evaluate the efficacy and safety of adding Superior Vena Cava Isolation (SVCI) to Pulmonary Vein Isolation (PVI) in patients with drug-refractory paroxysmal atrial fibrillation (PAF).
Design: Systematic review and meta-analysis of randomised controlled trials (RCTs) using the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) approach, supplemented with Trial Sequential Analysis (TSA) to assess evidence sufficiency.
Data Sources: We searched PubMed, EMBASE, the Cochrane Library (CENTRAL) and Web of Science for relevant studies published up to 13 July 2025.
Explainable Machine Learning for Estimating the Contrast Material Arrival Time in Computed Tomography Pulmonary Angiography.
J Thorac Imaging
September 2025
Department of Radiology, the Affiliated Wuxi People's Hospital of Nanjing Medical University, Wuxi People's Hospital, Wuxi Medical Center, Nanjing Medical University.
Purpose: To establish an explainable machine learning (ML) approach using patient-related and noncontrast chest CT-derived features to predict the contrast material arrival time (TARR) in CT pulmonary angiography (CTPA).
Materials And Methods: This retrospective study included consecutive patients referred for CTPA between September 2023 to October 2024. Sixteen clinical and 17 chest CT-derived parameters were used as inputs for the ML approach, which employed recursive feature elimination for feature selection and XGBoost with SHapley Additive exPlanations (SHAP) for explainable modeling.
