Lung transplantation in patients with previous or unknown oncological disease: evaluation of short- and long-term outcomes

Simple Summary Lung transplantation (LTX) is the treatment of choice for patients with end-stage lung disease but its role is still controversial in those with a history of malignancies. The aim of this study was to evaluate short- and long-term outcomes in patients submitted to LTX with a history of previous neoplasia or oncological disease detected in the native lung. Our study showed that this population had worse overall survival compared to a control group, emphasizing the importance of an accurate selection and a strict post-operative follow-up in this group of patients.Abstract The accurate selection of the recipient is a crucial aspect in the field of lung transplantation (LTX), especially if patients were previously affected by oncological disease. The aim of this bicentric retrospective study was to evaluate short- and long-term outcomes in patients with previous oncological disease or unknown neoplasia found on native lungs submitted to LTX, compared to a control group. A total of 433 patients were included in the analysis, 31 with malignancies (Group 1) and 402 without neoplastic disease (Group 2). The two groups were compared in terms of short- and long-term outcomes. Patients in Group 1 were older (median age 58 years vs. 50 years, p = 0.039) and mostly affected by idiopathic pulmonary fibrosis (55% vs. 40% p = 0.002). Even though in Group 1 a lower rate of late post-operative complications was found (23% vs. 45%, p = 0.018), the median overall survival (OS) was lower compared to the control group (10 months vs. 29 months, p = 0.015). LTX represents a viable therapeutic option for patients with end-stage lung disease and a history of neoplastic disease. However, every case should be carefully debated in a multidisciplinary setting, considering oncological (histology, stage, and proper disease free-interval) and clinical factors (patient's age and comorbidities). A scrupulous post-transplant follow-up is especially mandatory in those cases

Infection-Related Ventilator-Associated Complications in Critically Ill Patients with Trauma: A Retrospective Analysis

Background: Trauma is a leading cause of death and disability. Patients with trauma undergoing invasive mechanical ventilation (IMV) are at risk for ventilator-associated events (VAEs) potentially associated with a longer duration of IMV and increased stay in the intensive care unit (ICU). Methods: We conducted a retrospective cohort study aimed to evaluate the incidence of infection-related ventilator-associated complications (IVACs), possible ventilator-associated pneu- monia (PVAP), and their characteristics among patients experiencing severe trauma that required ICU admission and IMV for at least four days. We also determined pathogens implicated in PVAP episodes and characterized the use of antimicrobial therapy. Results: In total, 88 adult patients were included in the main analysis. In this study, we observed that 29.5% of patients developed a respiratory infection during ICU stay. Among them, five patients (19.2%) suffered from respiratory infections due to multi-drug resistant bacteria. Patients who developed IVAC/PVAP presented lower total GCS (median value, 7; (IQR, 9) vs. 12.5, (IQR, 8); p = 0.068) than those who did not develop IVAC/PVAP. Conclusions: We observed that less than one-third of trauma patients fulfilling criteria for ventilator associated events developed a respiratory infection during the ICU stay

Selection of Candidates for Lung Transplantation: The First Italian Consensus Statement

Lung transplantation is a well-established treatment for selected patients with advanced chronic respiratory insufficiency. Recognizing those patients with end-stage lung disease who might benefit from lung transplantation is a crucial task. Considering the presence of inadequate evidence-based practice, international and national scientific societies provided consensus opinions regarding the appropriate timing of listing. The Study Group for Thoracic Organs Transplantation (branch of the Italian Society for Organs Transplantation) promoted and realized a Delphi conference among the Italian lung transplantation centers to provide guidance to clinical practice based on international recommendations. The experts from the nine Italian centers completed two rounds of standardized questionnaires (answer rate, 100%): 42 statements received a consensus â\u89¥80%. The selected statements presented in this article are intended to assist Italian clinicians in selecting patients for lung transplantation

Peripheral venous catheter fracture with embolism into the pulmonary artery

Peripheral vein catheterization is generally considered a harmless procedure. Venous catheter rupture associated with pulmonary embolism is an unlikely but potentially serious complication. We report a case of a peripheral venous catheter (PVC) fracture with pulmonary artery embolization in the left lower lobe treated successfully by a surgical approach. The positioning of a PVC is not always a harmless procedure. Every time there are difficulties in positioning or in removal of a catheter device, it should be carefully inspected to verify integrity. The advisability of removal of these small foreign bodies is debated; percutaneous retrieval is preferred, while surgery should be discussed case by case

Modified Bentall operation: the double sewing ring technique

The Bentall-DeBono operation is the technique of choice for aortic root replacement. As more patients do not accept or have contraindications to lifelong anticoagulation, the biological Bentall operation is a good option for these patients, even though complex reoperations would then be required for bioprosthesis degeneration. We studied a modified technique to simplify the reoperations in patients undergoing biological Bentall procedure. A bioprosthetic valved conduit was obtained creating two separate sewing rings at different levels of the vascular graft. One ring was used to sew the bioprosthesis on the vascular graft. The second ring was used to fix the vascular graft on the native aortic annulus. In case of reoperation, the bioprosthesis could be removed cutting only the suture on the first ring. Then the same ring could be used to fix the new prosthesis. Since 2006, we have performed 12 biological Bentall operations with our modification. The mean age was 63.2 years (range 43-77 years), the mean cardiopulmonary time was 79 \ub1 12 min and the mean aortic cross-clamping time was 68 \ub1 10 min. We had no in-hospital mortality; the postoperative period was uneventful in all patients. In our experience this modification seems to be simple and reproducible, without increasing the operative risk and postoperative morbidity. \ua9 2007 European Association for Cardio-Thoracic Surgery

Beating heart bentall procedure for late type a aortic dissection in a patient with in-situ bilateral mammary artery bypass grafts

We report a case of a patient who had a type A aortic dissection after previous coronary bypass grafting. The in-situ right mammary artery had been anastomosed with the left anterior descending artery, the left mammary artery had been anastomosed to the obtuse marginal, and a vein graft had been used for the right coronary artery. All grafts were patent. The patients underwent a Bentall procedure on perfused heart. \ua9 2010 Wiley Periodicals, Inc

Aortic valve replacement with and without combined coronary bypass grafts in very elderly patients: Early and long-term results

Objective: The number of older patients being referred for aortic valve replacement with or without combined coronary bypass grafting (CABG) is increasing. The aim of this study was to evaluate operative risk factors, early and long-term results of isolated aortic valve and aortic valve replacement combined with CABG in octogenarians and nonagenarians. Methods: In the last 10 years, 285 very elderly patients who underwent aortic valve replacement either alone or in combination with coronary artery bypass grafts were retrospectively studied. The population was divided into two groups; isolated aortic valve replacement was performed in 188 patients (group A) and 97 patients had aortic valve replacement combined with coronary surgery (group B). Results: The overall hospital mortality was 5.3%, without statistical difference between groups. The incidence of low-output syndrome was higher in group B (P = 0.0001). The multivariate analysis for hospital mortality showed that urgency status, ejection fraction (EF) >35%, intra-operative variables such as clamping time, need for intra aortic balloon pump and post-operative variables such as prolonged ventilation, dialysis, post-operative myocardial infarction and re-thoracotomy for bleeding were independent prognostic factors for hospital mortality. The mean follow-up time was 49.03 \ub1 19 months. Survival at one, three and five years was 97.1 \ub1 1.8%, 92.2 \ub1 2.2% and 82.4 \ub1 3.6% for group A and 97.2 \ub1 2.0%, 88.4 \ub1 2.7% and 75.6 \ub1 3.2% for group B (P = 0.62), respectively. Age, male gender, post-operative myocardial infarction, urgency status, dialysis, low EF, mean aortic gradient were risk factors for the impaired survival. Conclusions: In our experience, a careful pre-operative evaluation has yielded good surgical results even in older patients with different comorbidities. Associated coronary grafts slightly increase the surgical risk. The role of revascularization on long-term morbidity and mortality is still not clear. It is essential to compare the results of percutaneous and trans-apical aortic valve replacement with the literature results of conventional aortic valve replacement with and without CABG before it can be used as an alternative for very older patients. \ua9 The Author 2011.

VATS right basal segmentectomy for NSCLC in a patient with systemic sclerosis

In recent decades, the thoracoscopic approach has been accepted as the gold standard to treat early stage non-small-cell lung cancer because it reduces postoperative pain and results in a shorter hospital stay. More recently, several techniques for performing sublobar resection have been reported that achieve a radical resection while sparing as much parenchyma as possible.\ua0 This video tutorial illustrates our technique for resecting the basal segments of the right lower lobe in a patient presenting with an adenocarcinoma in the right lower lobe. The patient also had systemic sclerosis, which led to pulmonary hypertension and fibrosis. Therefore, it was important to limit the parenchymal resection to save the apical segment of the lower lobe so as not to exacerbate the underlying conditions. The vascular and bronchial structures are readily identifiable, and the intersegmental plane can be easily accessed by clamping the associated bronchus while inflating the lung
