RESUMO

In this study, we aimed to determine the impact of lung transplantation (LTx) on pulmonary function tests (PFTs) and survival among patients with end-stage silicosis. We included patients with end-stage silicosis on the wait list for LTx, between January 1989 and July 2015 (N = 26). Sixteen of these patients received LTx; 10 were eligible, but did not undergo LTx (non-LTx) during the study period. Retrospective information on PFTs (spirometry [volumes and flows], 6-minute walking test [6MWT], and DLCO) was retrieved from patients' medical charts, including baseline information for all patients and follow-up information for the LTx. At baseline, most patients presented with spirometric and 6MWT values that were suggestive of severe disease (FEV1 /FVC 76.5 ± 29.7; 6MWT 267.4 ± 104.5 m). Significant increases in these values were observed at follow-up in the LTx (P = .036 and .151, respectively). The overall median survival of patients in the LTx and non-LTx was 3.35 years (95% CI: 0.16-14.38) and 0.78 years (95% confidence interval [CI]: 0.12-3.65) (P = 0.002), respectively. For patients with end-stage silicosis, LTx offers significant benefits regarding pulmonary function and survival when compared to non-LTx, and is a reliable tool to help this critical population of patients, whose only treatment option is LTx.

RESUMO

OBJECTIVE: To estimate the diagnostic accuracy of signal intensity of the lesion-to-spinal cord ratio (LSR) and apparent diffusion coefficient (ADC) in diffusion-weighted (DW) magnetic resonance imaging of pulmonary nodules suspicious for lung cancer in granulomatous lung disease-endemic regions. METHODS: Forty-nine patients with indeterminate solitary pulmonary nodules detected by chest computed tomography and histopathologically confirmed diagnoses were included in the study. DW images were analysed semiquantitatively by focusing regions of interest on the lesion and spinal cord at the same level (for LSR calculation). ADCs were estimated from ratios of the two image signal intensities. Ratios of T1 and T2 signal intensity between nodules and muscle were calculated for comparison. RESULTS: Mean ADCs ± standard deviations for lung cancer and benign lesions were 0.9 ± 0.2 and 1.3 ± 0.2 × 10(-3) mm(2)/s, respectively. Mean LSRs were 1.4 ± 0.3 for lung cancer and 1 ± 0.1 for benign lesions. ADCs and LSRs differed significantly between malignant and benign lesions (P < 0.001). Mean T2 signal intensity ratios also differed significantly between benign and malignant lesions (0.8 ± 0.2 vs. 1.6 ± 0.2; P < 0.05). CONCLUSIONS: DWI can help to differentiate malignant from benign lesions according to ADC and the LSR with good accuracy. KEY POINTS: • DW imaging can help differentiate malignant from benign pulmonary nodules. • ADC and LSR signal intensities had only small overlap between malignant and benign pulmonary nodules. • Mean T2 signal intensity ratios differed significantly between benign and malignant lesions.

RESUMO

Patients with preexisting lung cavities are at risk of developing intracavitary fungal colonization. Because Aspergillus spp. are the most commonly implicated fungi, these fungal masses are called aspergillomas. Their characteristic "ball-in-hole" appearance, however, may be found in a variety of other conditions that can produce radiologic findings mimicking aspergilloma. In this paper, we review the main diseases that may mimic the radiographic findings of aspergilloma, with brief descriptions of clinical, radiologic, and histopathologic findings.

RESUMO

Objective: To investigate the utility of computed tomography (CT) scans to detect and assess the margin status of pulmonary nodules that were insufflated after being resected by video-assisted thoracic surgery. Materials and Methods: This was a novel multicenter study conducted at two national referral centers for thoracic diseases. Patients suspected of having lung cancer underwent video-assisted thoracic surgery for the resection of pulmonary nodules, which were submitted to postoperative CT. Measurements from the CT scans were compared with the results of the histopathological analysis. Results: A total of 37 pulmonary nodules from 37 patients were evaluated. The mean age of the patients was 65 years (range, 36-84 years), and 27 (73%) were female. A CT analysis of insufflated specimens identified all 37 nodules, and 33 of those nodules were found to have tumor-free margins. The histopathological analysis revealed lung cancer in 30 of the nodules, all with tumor-free margins, and benign lesions in the seven remaining nodules. Conclusion: Postoperative CT of insufflated suspicious lung lesions provides real-time detection of pulmonary nodules and satisfactory assessment of tumor margins. This initial study shows that CT of insufflated lung lesions can be a valuable tool at centers where intraoperative histopathological analysis is unavailable.

Materiais e Métodos: Um inédito estudo multicêntrico foi conduzido em dois centros de referência nacional para doenças torácicas. Nódulos foram ressecados por cirurgia torácica videoassistida de pacientes com suspeita de câncer de pulmão e submetidos a TC pós-operatória. As medidas radiológicas da TC foram comparadas com as da análise patológica. Resultados: Um total de 37 pacientes foi avaliado. A idade média foi de 65 anos (variação: 36-84 anos) e 27 indivíduos (73%) eram do sexo feminino. A análise por TC dos espécimes insuflados identificou todas as 37 lesões e 33 delas com margens livres. A análise patológica revelou 30 casos de câncer de pulmão, todos com margens livres, e sete lesões não malignas. Conclusão: A TC pós-operatória de lesões pulmonares insufladas com suspeita de malignidade provê detecção em tempo real de nódulos pulmonares e aceitável avaliação de margens tumorais. Este estudo inicial demonstra que a TC de lesões pulmonares insufladas pode ser uma ferramenta valiosa em centros em que a análise histopatológica intraoperatória é indisponível.

RESUMO

BACKGROUND: Bronchoscopic lung volume reduction (BLVR) is a potential treatment for patients with severe emphysema, performed through the placement of unidirectional endobronchial valves (EBVs). Their benefits are only achieved in patients that significantly reduce lobar volume, and it is mandatory that the fissures are complete. Fissure evaluation is preferably done by computed tomography, but little is known if its evaluation corresponds to the anatomical findings. The aim of this study is to evaluate the accuracy of thoracic radiologists in the identification of complete fissures by multidetector computed tomography (MDCT) using maximum intensity projection (MIP) technique, compared with direct anatomical evaluation. METHODS: Prospective study, conducted in a single institution. Patients submitted to thoracic surgery had their fissures classified as complete or incomplete by thoracic surgeons and their preoperative chest scans evaluated by three radiologists, blinded for surgical evaluation. With the intraoperative categorization as a reference, the accuracy and concordance of the three thoracic radiologists' evaluation were calculated. The most experienced radiologist evaluated the fissures at two different moments to estimate the intra-observer agreement. RESULTS: There were included 67 patients, being 37 (55%) males, with a mean age of 64 years. The accuracy of radiological identification of complete fissures ranged from 76.8% for left posterior oblique fissure to 85.1% for left anterior oblique fissure, with the best performance achieved by the most experienced radiologist. The concordance of the radiological evaluation for fissure integrity compared to the surgical assessment (k) was 0.53-0.68. Intra-observer agreement ranged from 0.74 to 0.87. CONCLUSIONS: The evaluation of the fissure integrity by MDCT analysis using MIP technique by thoracic radiologists had high accuracy among the thoracic radiologists.

RESUMO

This study was conducted to evaluate whether a pulmonary rehabilitation program (PRP) is independently associated with survival in patients with idiopathic pulmonary fibrosis (IPF) undergoing lung transplant (LTx). This quasi-experimental study included 89 patients who underwent LTx due to IPF. Thirty-two completed all 36 sessions in a PRP while on the waiting list for LTx (PRP group), and 53 completed fewer than 36 sessions (controls). Survival after LTx was the main outcome; invasive mechanical ventilation (IMV), length of stay (LOS) in intensive care unit (ICU) and in hospital were secondary outcomes. Kaplan-Meier curves and Cox regression models were used in survival analyses. Cox regression models showed that the PRP group had a reduced 54.0% (hazard ratio = 0.464, 95% confidence interval 0.222-0.970, p = 0.041) risk of death. A lower number of patients in the PRP group required IMV for more than 24 hours after LTx (9.0% vs. 41.6% p = 0.001). This group also spent a mean of 5 days less in the ICU (p = 0.004) and 5 days less in hospital (p = 0.046). In conclusion, PRP PRP completion halved the risk of cumulative mortality in patients with IPF undergoing unilateral LTx.

RESUMO

OBJECTIVE:: To describe our experience with video-assisted thoracic surgery (VATS) for anatomic pulmonary resection at a referral center for thoracic surgery in Brazil. METHODS:: All patients who underwent anatomic pulmonary resection by VATS between 2010 and 2015 were included. Clinical and pathological data, as well as postoperative complications, were analyzed. RESULTS:: A total of 117 pulmonary resections by VATS were performed, of which 98 were lobectomies and 19 were anatomic segmentectomies. The mean age of the patients was 63.6 years (range, 15-86 years). Females predominated (n = 69; 59%). The mean time to chest tube removal was 2.47 days, and the mean length of ICU stay was 1.88 days. The mean length of hospital stay was 4.48 days. Bleeding ≥ 400 mL occurred in 15 patients. Conversion to thoracotomy was required in 4 patients. CONCLUSIONS:: Our results are similar to those published in major international studies, indicating that VATS is an important strategy for pulmonary resection. They also show that VATS can be safely performed with adequate training. This technique should be used more often for the treatment of lung diseases in Brazil.

RESULTADOS:: Foram realizadas 117 ressecções pulmonares por CTVA, sendo 98 lobectomias e 19 segmentectomias anatômicas. A média de idade foi de 63,6 anos (variação, 15-86 anos), sendo a maioria mulheres (n = 69; 59%). A média de tempo de permanência com dreno foi de 2,47 dias e a de estada em UTI foi de 1,88 dias. A média de tempo de internação foi de 4,48 dias. Sangramento ≥ 400 ml ocorreu em 15 pacientes. Houve conversão para toracotomia em 4 pacientes. CONCLUSÕES:: Nossos resultados vão ao encontro de publicações em grandes séries internacionais, corroborando que a CTVA é uma importante via de execução de ressecções pulmonares e que pode ser realizada com segurança quando há treinamento adequado, devendo ser mais utilizada no Brasil para o tratamento das doenças pulmonares.

RESUMO

BACKGROUND: The purpose of this study was to evaluate canine lungs obtained from non-heart-beating donors after unilateral lung transplantation subjected to partial liquid ventilation with perfluorodecalin. METHODS: Twelve donor dogs were killed and kept under mechanical ventilation for 3 hours. Heart-lung blocks were harvested after retrograde pulmonary hypothermic flush with Perfadex. Left lung grafts were randomly transplanted into 12 weight-matched recipient animals. Animals were divided into 2 groups: control (standard mechanical ventilation, n = 6) and PLV (partial liquid ventilation, n = 6). Forty-five minutes after transplantation, the animals in the PLV group received perfluorodecalin (15 ml/kg) via orotracheal tube. All animals received volume-controlled ventilation (FIO2) 1.0, PEEP 5 cm H(2)O) over 6 consecutive hours. Thereafter, blood-gas analysis, ventilatory mechanics and hemodynamics were registered at 30-minute intervals. After 6 hours of reperfusion the animals were killed and the transplanted lungs were extracted to obtain the wet/dry weight ratio. RESULTS: There were significant differences in pulmonary arterial pressure, which were higher in control group animals (p < 0.009). The control animals also showed higher arterial PaO(2) than those in the PLV group (p < 0.00001), but lower PaCO(2) (p < 0.008). The peak and plateau pressures were higher in the PLV group (p < 0.00001). Neither static compliance nor wet/dry weight ratios were different in between groups. CONCLUSIONS: PLV with perfluorodecalin yields functional results compatible with life in this model. Nonetheless, pulmonary gas exchange and mechanics were superior after reperfusion in animals given conventional mechanical ventilation up to 6 hours after left lung allotransplantation.

RESUMO

OBJECTIVE: To report the long-term follow-up of the first living-donor lobar lung transplantation performed in Latin America. DESCRIPTION: The patient was a 12-year-old boy with post-infectious obliterative bronchiolitis with end-stage pulmonary disease. He was on continuous oxygen support, presenting with dyspnea even during minimal activity. He underwent bilateral lobar lung transplantation with living donors. The procedure was performed with the left and right lower lobes of two different related donors. In the second side cardiopulmonary bypass was required. The transplant was uneventful, and the patient was extubated after 14 hours and discharged with 44 days, after resolution of infectious, immunological and drug-related complications. After 12 years of follow-up, he presents with adequate lung function and has resumed his habitual activities. COMMENTS: Living-donor lobar lung transplantation is a complex procedure feasible for the treatment of selected pediatric end-stage pulmonary disease. This particular population might benefit from this approach since the availability of pediatric donors is very scarce and the clinical course of pediatric advanced pulmonary disease may be unpredictable.

RESUMO

BACKGROUND: Lung transplantation (LT) has been established as a current therapy for selected patients with end-stage lung disease. Different prognostic factors have been reported by transplant centers. The objective of this study is to report our recent results with LT and to search for prognostic factors. METHODS: We performed a retrospective analysis of 130 patients who underwent LT at our institution from January 2004 to July 2009. Donor, recipient, intraoperative, and postoperative variables were collected. RESULTS: The mean age was 53.14 years (ranging from 8 to 72 years) and 80 (61.5%) were male. The main causes of end-stage respiratory disease were pulmonary fibrosis 53 (40.7%) and chronic obstructive pulmonary disease 52 (40%). The actuarial 1-year survival was 67.7%. Variables correlated with survival were age (P=0.004), distance in the 6-min walk test (P=0.007), coronary heart disease (P=0.001), cardiopulmonary bypass (P=0.02), intraoperative transfusion of red blood cells (P=0.016), increasing central venous pressure at 24th postoperative hour (P=0.001), increasing pulmonary capillary wedge pressure at 24th postoperative hour (P=0.01); length of intubation (P<0.01), reintubation (P=0.001), length of intensive care unit stay (P<0.001), abdominal complication (P=0.003), acute renal failure requiring dialysis (P<0.001), native lung hyperinflation (P=0.02), and acute rejection in the first month (P=0.03). In multivariate analysis, only dialysis (P=0.004, hazards ratio [HR] 2.68), length of intubation (P=0.004, HR 1.002 for each hour), and reintubation (P=0.003, HR 2.88) proved to be independent predictors. CONCLUSION: Analysis of variables in our cohort highlighted dialysis, longer mechanical ventilation requirement, and reintubation as independent prognostic factors in LT.

RESUMO

OBJECTIVE: To determine the main congenital lung malformations treated and the principal diagnostic methods employed, as well as the indications for surgical treatment and the results obtained, at a referral facility for pediatric thoracic surgery. METHODS: We reviewed the medical charts of 52 patients anatomopathologically diagnosed with congenital lung malformations and who had been submitted to pulmonary resection between January of 1997 and December of 2006. Exclusion criteria were age > 12 years and incomplete clinical data. The final sample comprised 35 patients. RESULTS: In this sample, the mean age was 31 months, and there was a predominance of males (n = 21). The anatomopathological findings were cystic adenomatoid malformation (n = 14), congenital lobar emphysema (n = 13), pulmonary sequestration (n = 8) and arteriovenous malformation (n = 1). The most common type of lung resection was left lower lobectomy (in 25.71%) followed by different types of segmentectomy (in 22.85%), left upper lobectomy (in 22.85%), right upper lobectomy (in 14.28%), right lower lobectomy (in 8.57%) and middle lobectomy (in 5.71%). Of the 35 patients, 34 (97.14%) were submitted to closed pleural drainage, with a mean duration of thoracic drainage of 3.9 days. Ten patients (28.5%) presented with postoperative complications. There were no deaths in our sample. CONCLUSIONS: Pulmonary resection for the treatment of congenital lung malformations is a safe procedure, presenting low morbidity and no mortality at a referral facility for pediatric thoracic surgery.

RESUMO

El síndrome de Carney es una enfermedad rara, con diferentes formas de presentación, que afecta principalmente al sexo femenino y es asintomática en la mayoría de los casos. Se caracteriza por la aparición de tumores, generalmente benignos, principalmente en el pulmón, la glándula suprarrenal y el estómago; sin embargo, se pueden afectar otros órganos como el esófago. Su tratamiento es principalmente quirúrgico. Se presenta el caso de una paciente con síndrome incompleto de Carney, manejada quirúrgicamente, con excelente resultado posoperatorio. Se hace una revisión de la literatura científica actual.


Carney's triad is a rare condition with multimodal presentations, which affects mainly females and remains asymptomatic in most cases. It is characterized by the appearance of tumors, usually benign, in lung, adrenal, and stomach, but it can also affect other organs like the esophagus. Treatment of these lesions is primarily surgical. The objective of this paper is to review the current literature and to report a case of an incomplete Carney's triad managed surgically with excellent postoperative results.

RESUMO

BACKGROUND: Bronchial carcinoid is an infrequent neoplasm with a neuroendocrine differentiation. Surgical treatment is the gold standard therapy, with procedures varying from sublobar resections to complex lung sparing broncoplastic procedures. This study evaluates the results of surgical treatment of bronchial carcinoids and its prognostic factors. PATIENTS AND METHODS: Retrospective review of 126 consecutive patients who underwent surgical treatment for bronchial carcinoid tumors between December 1974 and July 2007. RESULTS: There were 70 females (55%) and the mean age was 46 years, ranging from 17 to 81 years. Upon clinical presentation, 38 patients (30%) have had recurrent respiratory tract infection, 31 (24%) cough, 16 (12%) chest pain and 25 (20%) were asymptomatic. Preoperative bronchoscopic diagnosis was obtained in 74 cases (58.7%). The procedures performed were: 19 sublobar resections (14,9%), 58 lobectomies (46%), 8 bilobectomies (6.3%), 6 pneumonectomies (4.7%), 2 sleeve segmentectomies (1.5%), 26 sleeve lobectomies (20.6%) and 9 bronchoplastic procedures without lung resection (7.1%). Operative mortality was 1.5% (n = 2) and morbidity was 25.8% (n=32), including 12 respiratory tract infections and 4 reinterventions due to bleeding (3) and pleural empyema (1). Among the 112 patients available for follow-up, the overall survival at 3, 5 and 10 years was 89.2%, 85.5% and 79.8%, respectively. Five and 10-year survival for typical and atypical carcinoids were 91, 89% and 56, 47%, respectively. Overall disease-free survival at 5 years was 91.9% Statistical analysis showed that overall disease-free survival correlated with histology--typical vs. atypical--(p = 0.04) and stage (p = 0.02). CONCLUSION: Surgery provides safe and adequate treatment to bronchial carcinoid tumors. Histology and stage were the main prognostic factors.

RESUMO

Post-intubation tracheal injury is a rare and potentially fatal complication. Among the most common causes, cuff overinflation and repetitive attempts of orotracheal intubation in emergency situations are paramount. Diagnosis is based on clinical and radiological suspicion, confirmed by fiberoptic bronchoscopy. Both conservative and surgical management apply, and the decision-making process depends on the patient profile (comorbidities, respiratory stability), characteristics of the lesion (size and location) and the time elapsed between the occurrence of the injury and the diagnosis. We report the cases of three patients presenting tracheal laceration due to traumatic orotracheal intubation, two submitted to surgical treatment and one submitted to conservative treatment.
