Background: This study investigated the role of the thoracic skeletal muscle mass as a marker of sarcopenia on postoperative mortality in pleural empyema. Methods: All consecutive patients (n = 103) undergoing surgery for pleural empyema in a single tertiary referral center between January 2020 and December 2022 were eligible for this study. Thoracic skeletal muscle mass index (TSMI) was determined from preoperative computed tomography scans. The impact of TSMI and other potential risk factors on postoperative in‐hospital mortality was retrospectively analyzed. Results: A total of 97 patients were included in this study. The in‐hospital mortality rate was 13.4%. In univariable analysis, low values for preoperative TSMI (p = 0.020), low preoperative levels of thrombocytes (p = 0.027) and total serum protein (p = 0.046) and higher preoperative American Society of Anesthesiologists (ASA) category (p = 0.007) were statistically significant risk factors for mortality. In multivariable analysis, only TSMI (p = 0.038, OR 0.933, 95% CI: 0.875–0.996) and low thrombocytes (p = 0.031, OR 0.944, 95% CI: 0.988–0.999) remained independent prognostic factors for mortality. Conclusions: TSMI was a significant prognostic risk factor for postoperative mortality in patients with pleural empyema. TSMI may be suitable for risk stratification in this disease with high morbidity and mortality, which may have further implications for the selection of the best treatment strategy.

Objective: The presence of a significant left subclavian artery stenosis may occasionally lead to blood flow reversal through a LIMA-to-coronary artery bypass graft during left arm exertion; with "stealing" of myocardial blood supply. The aim of this study was to review our experience with carotid-subclavian bypass in patients with post-CABG coronary-subclavian steal syndrome. Methods: This is a retrospective review of all patients who underwent carotid-subclavian bypass grafting for post-CABG coronary-subclavian steal syndrome at Mainz University Hospital between 2006 and 2015. Cases were identified in our institutional database, and data were retrieved from surgical records, imaging studies, and follow-up records. Results: Nine patients (all males, mean age of 69.1 years) underwent surgical treatment for post-CABG coronary-subclavian steal syndrome. Medium interval between original CABG and carotid-subclavian bypass grafting was 86.1 months. There were no perioperative deaths, strokes or myocardial infarctions. At a mean follow-up period of 79.9 months, all patients remained asymptomatic and all carotid-subclavian bypass grafts remained patent. One patient required stenting of a common carotid artery stenosis proximal to the graft anastomosis site, and coronary artery stenting was required in four patients in regions other than those supplied by the patent LIMA graft. Conclusion: Carotid-subclavian bypass surgery is a safe treatment option even in patients with multivessel disease and severe comorbidities and should be taken into consideration in patients who are deemed fit for surgery and those who would benefit from the excellent long-term patency rates.

Background: Postoperative air leaks are a common complication after lung surgery. They are associated with prolonged hospital stay, increased postoperative pain and treatment costs. The treatment of prolonged air leaks remains controversial. Several treatments have been proposed including different types of sealants, chemical pleurodesis, or early surgical intervention. The aim of this review was to analyze the impact of autologous blood pleurodesis in a systematic way. Methods: A systematic review of the literature was conducted until July 2020. Studies with more than five adult patients undergoing lung resections were included. Studies in patients receiving blood pleurodesis for pneumothorax were excluded. The search strategy included proper combinations of the MeSH terms "air leak", "blood transfusion" and "lung surgery". Results: Ten studies with a total of 198 patients were included in the analysis. The pooled success rate for sealing the air leak within 48 h of the blood pleurodesis was 83.7% (95% CI: 75.7; 90.3). The pooled incidence of the post‐interventional empyema was 1.5%, with a pooled incidence of post‐interventional fever of 8.6%. Conclusions: Current evidence supports the idea that autologous blood pleurodesis leads to a faster healing of postoperative air leaks than conservative treatment. The complication rate is very low. Formal recommendations on how to perform the procedure are not possible with the current evidence. A randomized controlled trial in the modern era is necessary to confirm the benefits.
