- Stents for Bronchial Stenosis After Lung Transplantation: Should They Be Removed?(2015) FONESCA, H. V. S.; IUAMOTO, L. R.; MINAMOTO, H.; ABDALLA, L. G.; FERNANDES, L. M.; CAMARGO, P. C. L.; SAMANO, M. N.; PEGO-FERNANDES, P. M.Background. Airway complications after lung transplantation are the major cause of morbidity, affecting up to 33% of all cases. Bronchial stenosis is the most common complication. The use of stents has been established as the most effective therapy; however, their removal is recommended after 3-6 months of use. We have been using self-expandable stents as a definitive treatment and remove them only if necessary. For this report, we evaluated the use of self-expandable stents as a definitive treatment for bronchial stenosis after lung transplantation. Methods. We performed a retrospective cohort study to evaluate patients with bronchial stenosis from August 2003 to April 2014. Clinical and pulmonary function test data were collected. Results. Two hundred lung transplants were performed, 156 of which were bilateral. Sixteen patients experienced airway complications: 4 had dehiscence, 2 necrosis, and 10 bronchial stenosis. Of these patients, 7 had undergone bilateral procedures, and 2 patients developed stenosis in both sides. Twelve anastomotic stenoses were observed. The follow-up after stenting ranged from 1 to 7 years. All patients had increased lung function, and 4 remained stable with sustained increase in pulmonary function without episodes of infection. Three patients required removal of their prosthesis 6 months to 1 year after implantation because of complications. Two patients died owing to unrelated causes. Conclusions. Definitive treatment of bronchial stenosis with self-expandable stents is a viable option. The 1st year seems to be the most crucial for determining definitive treatment, because no patients required removal of their stent after 1 year.

- Posterior Reversible Encephalopathy Syndrome in Lung Transplantation: 5 Case Reports(2014) ARIMURA, F. E.; CAMARGO, P. C. L. B.; COSTA, A. N.; TEIXEIRA, R. H. O. B.; CARRARO, R. M.; AFONSO JR., J. E.; CAMPOS, S. V.; SAMANO, M. N.; FERNANDES, L. M.; ABDALLA, L. G.; PEGO-FERNANDES, P. M.Posterior reversible encephalopathy syndrome (PRES) is a cliniconeuroradiologic entity characterized by typical neurologic symptoms with characteristic cerebral image alterations. It has been reported in solid organ transplantations, especially related to the use of calcineurin inhibitors. The incidence of PRES in lung transplantation is unknown and probably under-reported in the literature. Here we describe 5 cases of PRES after bilateral lung transplantation. One of the reported cases was the first in the literature in which the neurologic onset precluded the introduction of calcineurin inhibitor. Therefore, although calcineurin inhibitors are known to play an important role in the development of PRES in the setting of lung transplantation, other causes seems to be involved in the physiopathology of this syndrome.

Tracheal diverticulum (TD) is a rare entity in clinical practice, accidentally found by imaging methods. It is a potential factor for the development of chronic respiratory infections, contributing to the progression of preexisting lung diseases and putting the success of lung transplantation at risk.Objectives. This paper reports 2 cases of TD with atypical clinical presentation in post-lung transplant patients with recurrent infections and aims to present the importance of this differential diagnosis.Discussion. Case 1: A 30-year-old man with terminal lung disease underwent bilateral lung transplantation with a satisfactory postoperative period. He presented with TD as a focus of recurrent infection associated with persistent hemoptysis. Indicated for surgical resection (cervicotomy with resection of tracheal diverticulum), without complications. He evolved uneventfully in the postoperative period and was clinically stable at follow-up. Case 2: A 57-year-old woman with hypersensitivity pneumonia associated with secondary pulmonary arterial hypertension and bronchiectasis underwent bilateral lung transplantation without complications. She presented with TD as a focus of infection associated with esophageal symptoms. Indicated for the surgical approach (cervicotomy with resection of tracheal diverticulum), she was asymptomatic at follow-up.Conclusion. Conservative treatment is recommended in elderly and asymptomatic patients. Surgical resection is based on the recurrence of symptoms and failure of clinical therapy and is the preferred approach for reported cases.
conferenceObject The Use of ECMO in Lung Transplant and hybrid Cannulation: 10 Years of a Single Center Experience(2022) SANTOS, Samuel; RAZUK, Mauro; POLA, Flavio; NAKAHIRA, Evelyn; ABDALLA, Luis G.; FERNANDES, Lucas M.; PEGO-FERNANDES, Paulo M.- Abdominal Complications After Lung Transplantation in a Brazilian Single Center(2017) COSTA, H. F.; REIS, F. P. dos; GOMES-JUNIOR, O.; FERNANDES, L. M.; ABDALLA, L. G.; CAMPOS, S. V.; TEIXEIRA, R. H. O. B.; SAMANO, M. N.; PEGO-FERNANDES, P. M.Surgical and nonsurgical abdominal complications have been described after lung transplantation. However, there is limited data on this event in this population. The objective of this study was to analyze the incidence of abdominal complications in patients undergoing lung transplantation at the Heart Institute of the Faculty of Medicine, University of Sao Paulo (InCor-HCFMUSP) between the years 2003 and 2016. The main causes of abdominal complications were inflammatory acute abdomen (7 patients; 14%), obstructive acute abdomen (9 patients; 18%), gastroparesis (4 patients; 8%), distal intestinal obstruction syndrome (4 patients; 8%), perforated acute abdomen (7 patients; 14%), cytomegalovirus (CMV; 6 patients; 12%), and other reasons (12 patients; 26%). Separating these patients according to Clavien-Dindo classification, we had 21 patients (43%) with complications grade II, 4 patients (8%) with complications grade ilia, 7 patients (14%) with grade Illb complications, 7 patients (14%) with grade IV complications, and 10 patients (21%) with grade complications V. In conclusion, abdominal disorders are seriously increased after lung transplantation and correlate with a high mortality. Early abdominal surgical complication has worse prognosis.
