Saphenous vein graft aneurysm is a relatively rare but serious complication of coronary artery bypass grafting (CABG). The diagnosis of such cases is clinically challenging and requires a high index of suspicion, especially if presented atypically or very late after CABG. Herein, we report a case of a saphenous vein graft pseudoaneurysm that presented 36 years after CABG and was masquerading as a right atrial myxoma on serial echocardiograms over a 2-year follow-up period.

Subarachnoid hemorrhage (SAH) is a type of hemorrhagic stroke with high morbidity, mortality and disability, and early brain injury (EBI) after SAH is crucial for prognosis. Recently, stem cell therapy has garnered significant attention in the treatment of neurological diseases. Compared to other stem cells, dental pulp stem cells (DPSCs) possess several advantages, including abundant sources, absence of ethical concerns, non-invasive procurement, non-tumorigenic history and neuroprotective potential.

Objectives: Studies comparing alternative autologous vein grafts (AAVG) to single-segment great saphenous vein (ssGSV) grafts report mixed results. The status of AAVG as first choice when ssGSV is unavailable is not unequivocal, based on current evidence. Our study compares results between AAVG and ssGSV in lower extremity bypass surgery.

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.

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.
