    The scarcity of viable donor organs remains a restrictive bottleneck in thoracic transplantation. To expand the donor pool, transplant networks increasingly utilize "extended-criteria" or marginal donor lungs. However, brain-dead or circulatory-death donors exist in a hypercoagulable, prothrombotic state due to systemic inflammation, prolonged immobilization, and invasive central venous..

    Preoperative Diagnosis: Malignant lung tumor of the right lung with extensive invasion into the Right Pulmonary Artery (RPA) and the right-sided superior and inferior pulmonary veins.   Procedure performed: Right radical pneumonectomy, en bloc resection of invaded vascular structures, establishment of central Cardiopulmonary Bypass (CPB) via bicaval cannulation,..

    Surgical Procurement of a Donor Heart with Complex Congenital and Venous Anomalies: PLSVC, Coronary Sinus Dilation, RA Aneurysm, and Patent Ductus Arteriosus (PDA) In thoracic organ transplantation, discovering complex congenital and venous anomalies in a donor organ is a high-stakes scenario. While an isolated persistent left superior vena..

    Partial Heart and Lung Transplantation: Maximizing Donor Organ Utilization Through Two-Recipient Transplantation Partial heart and lung transplantation is an innovative organ utilization strategy that allows transplantation of thoracic organs from a single donor into two separate recipients. This approach aims to maximize the use of scarce donor organs..

      Managing aortic and pulmonary root enlargement in donor organs requires a meticulous, proactive strategy to ensure structural stability before implantation into an emergency recipient. Utilizing a double Personalized External Aortic Root Support (PEARS) approach with polytetrafluoroethylene (PTFE) mesh provides a tailored, non-reconstructive solution that stabilizes both the..

    Managing complex congenital anomalies during multi-organ donor procurement requires precise surgical tailoring to preserve the structural integrity of the heart. When faced with a donor harboring both a Double Aortic Arch (a complete vascular ring) and a Bovine Arch configuration (where the left common carotid artery arises from..

  Oxygenated Cardioplegia (OCP) using a blood-based vehicle represents a significant shift from traditional cold crystalloid preservation during multi-organ heart and lung procurements. By leveraging a mixture of oxygenated donor blood and cold cardioplegic crystalloid substrate, this technique minimizes the profound metabolic shock of initial ischemia by maintaining aerobic cellular..
