We report the case of a 63-year-old female patient who was evaluated due to a solitary pulmonary nodule. The final diagnosis was a solitary peripheral pulmonary artery saccular aneurysm. The patient was submitted to a pulmonary lobectomy with excellent recovery. Peripheral pulmonary artery aneurysms that arise from segmental or intrapulmonary branches are extremely rare, and their management is still controversial.

BACKGROUND: Tracheal resection and anastomosis is the gold standard for the treatment of tracheal stenosis. The objective of this study is to evaluate the complications after tracheal resection for benign stenosis and the predicting factors for such complications. METHODS: A retrospective study was made involving patients with benign tracheal or laryngotracheal stenosis who underwent surgical resection and reconstruction between February 2002 and January 2009. Complications related and unrelated to the anastomosis were studied. Categorical variables were presented as percentage and continuous variables as mean and standard deviation. Predicting factors were determined by univariate analysis. Factors with p less than 0.05 were used for multivariate regression. Logistic regression models were also employed for dependent variables. Statistical significance was set for p less than 0.05. RESULTS: Ninety-four patients (18 female, 76 male) were included. Complications occurred in 42 (44.6%). Twenty-one percent had anastomotic complications. The most common complication was restenosis (16%). Nonanastomotic complications occurred in 23.2%. Wound infection occurred in 10.6%. Clinical comorbidities, previous tracheal resection, and the length of tracheal resection were statistically significant factors for complications. Previous tracheal resection was the most significant factor and was highly associated with anastomotic complications (odds ratio 49.965, p=0.012). The greatest number of complications was found in the laryngotracheal reconstruction group, and in resections more than 4 cm. Mean follow-up was 19±14 months. At the end of the study, 86 patients (91.4%) were breathing normally. There was no mortality in this series. CONCLUSIONS: Comorbidities, previous tracheal resection, and the length of tracheal resection more than 4 cm were statistically significant factors for the onset of complications.

OBJECTIVE: Few studies to date have evaluated the videothoracoscopic approach of the internal thoracic lymphatic chain. However, the histological evaluation of lymph nodes is essential for patients with breast cancer who show lymph node uptake at scintigraphy in the preoperative period and also for patients with lymphoma who have exclusive uptake in these lymph nodes at positron emission tomography for recurrence assessment. Our goal was to evaluate the safety and the change in oncologic approach through this minimally invasive technique. METHODS: This is a review of the prospectively collected data in a group of patients undergoing thoracoscopic biopsy of the thoracic lymphatic chain in patients with breast cancer and lymphoma carried out in our institution between September 2010 and June 2012. The analyzed variables include age, histological type, operated hemithorax, number of resected lymph nodes, neoplastic involvement of the resected lymph nodes, duration of chest tube drainage, length of hospital stay, and perioperative mortality. Complications such as subcutaneous emphysema and necessity for blood transfusion were also evaluated. RESULTS: Thoracoscopic biopsy was successfully performed in 16 patients, of whom 14 had breast cancer and 2 had lymphoma. The surgical biopsy results changed the treatment in the two patients with lymphoma and avoided radiotherapy in the eight patients with breast cancer who did not have metastases. CONCLUSIONS: The use of the thoracoscopic assessment of the internal thoracic lymphatic chain seems safe and resulted in therapy modification in more than half of our patients, suggesting that it is an effective technique for staging in selected breast cancer and lymphoma cases.

BACKGROUND: Decannulation is the ultimate therapeutic goal for patients who undergo stenting because of inoperable benign tracheal stenosis. In this study, our objectives were to evaluate whether long-term airway stenting allows decannulation in patients with benign tracheal stenosis who were deemed inoperable and to identify possible predictive factors for successful decannulation (SD). METHODS: Retrospective cohort study including all patients with inoperable benign tracheal stenosis who underwent tracheal stenting in our tertiary-care university-based institution from 1998 to 2008. For benign stenosis, we use only silicone stents (T tubes, Dumon stents, and Y stents). The main outcome was SD, which was defined as removal of the tracheal stent followed by absence of respiratory symptoms and no requirement for new dilation procedures for at least 6 months. A Kaplan-Meier curve was built to evaluate SD in 5 years, and we used a Cox model to evaluate predictors for a SD. RESULTS: Ninety-two patients were included, and during the study period 21 were decannulated. However, 2 of them had to undergo new airway procedures and were considered to represent failure. Therefore, 19 patients were successfully decannulated. According to the Kaplan-Meier estimate, the SD rate in 5 years was 27.5%. The mean follow-up time after SD was 34.3 ± 33.9 months (range, 6 to 108 months). Cox regression showed only 1 significant factor: tracheostomy before stent insertion caused a threefold increase in the likelihood of the patient remaining with a tracheal stent (p = 0.048). CONCLUSIONS: Tracheal stenting may be considered a curative therapeutic approach in as many as 27.5% of patients with inoperable benign tracheal stenosis.
