Saphenous vein graft pseudoaneurysms are rare and potentially fatal complications after coronary artery bypass graft surgery. Here we present an 11-cm saphenous vein graft pseudoaneurysm from a 20-year-old vein graft to the obtuse marginal artery. The pseudoaneurysm was directly located beneath the sternum and adjacent to two patent grafts. Therefore, we used a novel approach to access the aorta through a right thoracotomy, and using a pericardial patch, we closed the ostia to the pseudoaneurysm. Postoperatively there was no longer flow into the aneurysm, and at 1-year follow-up the patient is doing well.

Second-line treatment patterns and outcomes in advanced HCC after progression on atezolizumab/bevacizumab.

Background & Aims: Atezolizumab/bevacizumab (A/B) is now a standard first-line treatment for advanced hepatocellular carcinoma (HCC), but the optimal second-line regimen is not known. We evaluated real-world treatment patterns and outcomes to investigate factors associated with post-progression survival (PPS).
Methods: In this multicenter, international, retrospective study, we examined clinical characteristics and outcomes of patients with advanced HCC who progressed on first-line A/B.
Resection and Reconstruction of the Inferior Vena Cava Using a Tunneled Peritoneal Graft for Renal Tumor With Thrombus: Venous Compensation via the Azygos Vein Following Early Graft Occlusion.

Inferior vena cava (IVC) invasion by tumor thrombus poses a significant surgical challenge, often requiring vascular reconstruction. Standard methods, including prosthetic and autologous vein grafts, have limitations such as infection risks, anticoagulation demands, and increased costs. We present the case of a 66-year-old male with a right renal tumor (T3bN0M0, Neves Zincke II) and gross hematuria, who underwent radical nephrectomy with open thrombectomy.

Background: The survival advantages of bilateral internal thoracic artery (BITA) grafts in coronary artery bypass surgery (CABG) remain unclear. Therefore, this study aims to systematically evaluate the time-dependent influence of BITA on long-term survival in elective CABG patients presenting with stable multi-vessel coronary artery disease.
Methods: Data from 3,693 patients undergoing isolated CABG with single internal thoracic artery (SITA) or BITA, with or without additional vein grafts, between 2002 and 2012 were retrospectively analyzed.

Background: The fluorescent dye indocyanine green (ICG) has been used to identify anatomical structures intraoperatively in coronary artery bypass grafting (CABG). This study aimed to evaluate the feasibility of using ICG to assess graft patency and territorial distribution of myocardial reperfusion during CABG.
Methods: Porcine arrested hearts (n = 18) were used to evaluate territorial distribution of native coronary arteries and of a coronary bypass constructed with porcine saphenous vein graft (SVG) using ICG.
Introduction: Veno-occlusive disease/sinusoidal obstruction syndrome (VOD/SOS) is a potentially life-threatening condition characterised by obstruction of the small veins of the liver. Although typically associated with haematopoietic stem cell transplantation, VOD/SOS may also occur following intensive multimodal chemotherapy regimens. In children, symptoms of VOD/SOS are refractory thrombocytopaenia, weight gain, hepatomegaly, ascites and fluid retention, hyperbilirubinaemia and sometimes right upper quadrant pain.
