- Pediatric lung transplantation: 10 years of experience(2014) CAMARGO, Priscila C. L. B.; PATO, Eduardo Z. S.; CAMPOS, Silvia V.; AFONSO JR., Jose E.; CARRARO, Rafael M.; COSTA, Andre N.; TEIXEIRA, Ricardo H. O. B.; SAMANO, Marcos N.; PEGO-FERNANDES, Paulo M.Lung transplantation is a well-established treatment for advanced lung diseases. In children, the diseases that most commonly lead to the need for a transplantation are cystic fibrosis, pulmonary hypertension, and bronchiolitis. However, the number of pediatric lung transplantations being performed is low compared with the number of transplants performed in the adult age group. The objective of this study was to demonstrate our experience with pediatric lung transplants over a 10-year period in a program initially designed for adults.
- Avaliação e recondicionamento de pulmões doados para transplante por meio da perfusão pulmonar ex vivo(2019) ABDALLA, Luis Gustavo; OLIVEIRA-BRAGA, Karina Andrighetti de; FERNANDES, Lucas Matos; SAMANO, Marcos Naoyuki; CAMERINI, Paula Refinetti; PEGO-FERNANDES, Paulo ManuelObjective: To assess the feasibility and impact of ex vivo lung perfusion with hyperoncotic solution (Steen Solution (TM)) in the utilization of these organs in Brazil. Methods: In this prospective study, we subjected five lungs considered to be high risk for transplantation to 4 hours of ex vivo lung perfusion, with evaluation of oxygenation capacity. High-risk donor lungs were defined by specific criteria, including inflammatory infiltrates, pulmonary edema and partial pressure of arterial oxygen less than 300mmHg (inspired oxygen fraction of 100%). Results: During reperfusion, the mean partial pressure of arterial oxygen (inspired oxygen fraction of 100%) of the lungs did not change significantly (p=0.315). In the first hour, the mean partial pressure of arterial oxygen was 302.7mmHg (+/- 127.66mmHg); in the second hour, 214.2mmHg (+/- 94.12mmHg); in the third hour, 214.4mmHg (+/- 99.70mmHg); and in the fourth hour, 217.7mmHg (+/- 73.93mmHg). Plasma levels of lactate and glucose remained stable during perfusion, with no statistical difference between the moments studied (p=0.216). Conclusion: Ex vivo lung perfusion was reproduced in our center and ensured the preservation of lungs during the study period, which was 4 hours. The technique did not provide enough improvement for indicating organs for transplantation; therefore, it did not impact on use of these organs.

- A simple technique can reduce cardiopulmonary bypass use during lung transplantation(2016) SAMANO, Marcos N.; IUAMOTO, Leandro R.; FONSECA, Hugo V. S.; FERNANDES, Lucas M.; ABDALLA, Luis G.; JATENE, Fabio B.; PEGO-FERNANDES, Paulo M.Cardiopulmonary bypass causes an inflammatory response and consumption of coagulation factors, increasing the risk of bleeding and neurological and renal complications. Its use during lung transplantation may be due to pulmonary hypertension or associated cardiac defects or just for better exposure of the pulmonary hilum. We describe a simple technique, or open pericardium retraction, to improve hilar exposure by lifting the heart by upward retraction of the pericardial sac. This technique permits lung transplantation without cardiopulmonary bypass when bypass use is recommended only for better exposure.
