RESUMO
The main limitation to increased rates of lung transplantation (LT) continues to be the availability of suitable donors. At present, the largest source of lung allografts is still donation after the neurologic determination of death (brain-death donors, DBD). However, only 20% of these donors provide acceptable lung allografts for transplantation. One of the proposed strategies to increase the lung donor pool is the use of donors after circulatory-determination-of-death (DCD), which has the potential to significantly alleviate the shortage of transplantable lungs. According to the Maastricht classification, there are five types of DCD donors. The first two categories are uncontrolled DCD donors (uDCD); the other three are controlled DCD donors (cDCD). Clinical experience with uncontrolled DCD donors is scarce and remains limited to small case series. Controlled DCD donation, meanwhile, is the most accepted type of DCD donation for lungs. Although the DCD donor pool has significantly increased, it is still underutilized worldwide. To achieve a high retrieval rate, experience with DCD donation, adequate management of the potential DCD donor at the intensive care unit (ICU), and expertise in combined organ procurement are critical. This review presents a concise update of lung donation after circulatory-determination-of-death and includes a step-by-step protocol of lung procurement using abdominal normothermic regional perfusion.

Post-thoracotomy wound dehiscence after a lung transplant carries with it morbidity in the postoperative period. While this complication has been widely reported in the literature after a clamshell incision, the thoracotomy dehiscence's surgical solution has not received much emphasis. We present an original technical solution to deal with this complication, performed successfully in a 62-year-old woman diagnosed as having idiopathic pulmonary hemosiderosis after a single lung transplant. This surgical treatment consists of necrotic rib tissue removal, pleural effusion drainage, pulmonary adhesion removal, and chest wall defect reparation with bioabsorbable mesh. This operative technique results safe and effective for thoracotomy dehiscence reparation.
