Background

The cardiothoracic surgery workforce remains underrepresented in racial and ethnic diversity. Achieving greater representation at national levels is vital for signaling inclusivity and encouraging aspiring trainees. We aimed to characterize the diversity of individuals selected as moderators in the setting of a national cardiothoracic surgical meeting.

Methods

Program records from The Society of Thoracic Surgeons (STS) Annual Meetings (2015-2024) were reviewed. Moderators selected by the STS program taskforce were identified, and their perceived race/ethnicity was assessed by 5 independent reviewers. Trends in racial and ethnic distribution were analyzed using a multinomial logistic regression model.

Results

From 2015-2024, 450 moderators were identified. Of these, 319 (70.9%) were perceived as White/Caucasian, 17 (3.8%) as Black/African American/Afro Caribbean, 104 (23.1%) as Asian/South Asian/West Asian, and 10 (2.2%) as Hispanic/Latino. The likelihood of a moderator being Black increased significantly over time (11.4% per year, P = .033). No significant changes were observed for other groups. The proportion of Hispanic/Latino moderators remained below 5%, with no notable trend.

Conclusions

Despite an encouraging increase in Black moderators, overall diversity among moderators remains limited, with White/Caucasian individuals overwhelmingly represented and Hispanic/Latino individuals severely underrepresented. Increasing diversity at academic meetings is essential to fostering inclusivity, inspiring future cardiothoracic surgeons, and ultimately improving patient care through a more representative workforce.

背景：心胸外科工作人员在种族和民族多样性方面仍然代表性不足。在国家层面实现更大的代表性对于发出包容性信号和鼓励有抱负的学员至关重要。我们的目的是描述在全国心胸外科会议中被选为主持人的个体的多样性。方法回顾胸外科学会（STS）年会（2015-2024）的会议记录。确定由STS项目工作组选择的主持人，并由5名独立评审员评估其感知的种族/民族。使用多项逻辑回归模型分析了种族和民族分布的趋势。结果2015-2024年共鉴定出450名调节因子。其中，319人（70.9%）被认为是白人/高加索人，17人（3.8%）被认为是黑人/非洲裔美国人/非洲裔加勒比人，104人（23.1%）被认为是亚洲/南亚/西亚人，10人（2.2%）被认为是西班牙裔/拉丁裔。随着时间的推移，黑人成为调节者的可能性显著增加（每年11.4%,P = 0.033）。其他组未见明显变化。西班牙/拉丁裔主持人的比例保持在5%以下，没有明显的趋势。结论：尽管黑人审核员人数有了令人鼓舞的增长，但审核员的总体多样性仍然有限，白人/高加索人占绝大多数，西班牙裔/拉丁裔人的代表性严重不足。增加学术会议的多样性对于促进包容性，激励未来的心胸外科医生，并最终通过更具代表性的工作人员改善患者护理至关重要。

We present a dramatic case of coarctation of the descending aorta. Standard surgical treatment led to graft infection, necessitating a complex series of additional surgical procedures—all without resolution. A classical “thromboexclusion” procedure accomplished durable, decades-long survival. The thromboexclusion produced the expected thrombotic occlusion of the descending aorta. The extra-anatomic ascending-to-abdominal bypass graft provided long-term blood flow to the abdominal organs and lower extremities.

我们提出一个戏剧性的病例缩窄的降主动脉。标准的手术治疗导致移植物感染，需要一系列复杂的额外手术，所有这些都没有解决。一个经典的“血栓排除”程序实现持久的，长达数十年的生存。血栓排除产生了预期的血栓性降主动脉闭塞。解剖外的上升至腹部旁路移植术为腹部器官和下肢提供了长期的血液流动。

Anterior chest wall reconstruction after sternal resection remains challenging. Implants and prosthetic reconstructive materials should offer ample tissue ingrowth, maintain structural integrity and physiology, minimize infection risk, and maximize cosmesis. Custom titanium implants offer little or no tissue ingrowth and are not modifiable intraoperatively. Reports of polyetheretherketone (PEEK)-based sternal implants cite issues with the above and overall wound healing. Polyetherketoneketone (PEKK)-based implants have been increasingly utilized in odontoid, craniomaxillofacial and vertebral reconstruction. We present a case of sternal resection and reconstruction using a custom printed 3-dimensional PEKK-based implant.

胸骨切除术后前胸壁重建仍然具有挑战性。植入物和假体重建材料应提供充足的组织长入，保持结构完整性和生理机能，最大限度地降低感染风险，并最大限度地提高美观性。定制的钛植入物很少或没有组织长入，术中不可修改。基于聚醚醚酮（PEEK）的胸骨植入物的报道引用了上述问题和整体伤口愈合。聚醚酮酮（PEKK）基种植体越来越多地应用于齿状突、颅颌面和椎体重建。我们提出一例胸骨切除和重建使用定制打印三维pek为基础的植入物。

Congenital thoracic lymphovenous aneurysms are exceedingly rare. They often present with compressive symptoms or thrombosis, necessitating surgical excision for symptom relief and cosmetic reasons. We report a symptomatic subclavian vein aneurysm in a 4-month-old infant who presented with a rapidly enlarging axillary mass. Multimodal imaging with ultrasound, computed tomography, and magnetic resonance imaging confirmed the diagnosis of subclavian vein aneurysm. The patient underwent surgical resection, and histology confirmed a lymphovenous malformation. Postoperative recovery remained uneventful aside from a chylothorax. On early follow-up at 15 months, the child remained well with no recurrence or residual symptoms.

先天性胸淋巴静脉动脉瘤极为罕见。他们通常表现为压迫症状或血栓形成，需要手术切除以缓解症状和美容原因。我们报告一个症状锁骨下静脉动脉瘤在一个4个月大的婴儿谁提出了一个迅速扩大的腋窝肿块。超声、计算机断层及磁共振多模态影像证实锁骨下静脉动脉瘤的诊断。患者接受手术切除，组织学证实为淋巴静脉畸形。术后除乳糜胸外恢复正常。在15个月的早期随访中，儿童保持良好，无复发或残留症状。

Epidermal Growth Factor Receptor Mutation in Resectable Lung Cancer: Association With Survival Outcomes 可切除肺癌的表皮生长因子受体突变：与生存结果的关系

Annals of thoracic surgery short reports

Background

Case series suggest comparable long-term survival between patients with epidermal growth factor receptor–mutant (EGFRmu) and wild-type (EGFRwt) lung cancer after surgery. We aimed to analyze our experience with stage I-III adenocarcinoma patients who underwent surgery, hypothesizing similar long-term survival.

Methods

From 2733 lobectomies (2013-2023), 578 adenocarcinoma patients underwent complete mutational analysis. Exclusions were stage IV disease and inadequate EGFR testing. Of 112 EGFRmu and 466 EGFRwt patients, baseline characteristics were compared, and survival trends and prognostic factors were analyzed.

Results

EGFRmu patients were more often female (P < .001), never-smokers (P < .001), and had stage I disease (P < .001). EGFRmu patients had better 5- and 10-year survival (55% vs 25%, P < .001), which may reflect baseline differences. Multivariable analysis identified tumor stage, age, male sex, and EGFRwt as predictors of mortality. Three-year disease-free survival was higher in EGFRmu patients compared with those with EGFRwt (75% vs 58%, P = .003). In multivariable analysis, EGFRwt status was not predictive of 5-year mortality in the absence of metastatic recurrence (hazard ratio, 1.05; 95% CI, 0.44-2.51; P = .92), but was significantly associated with increased risk of death following metastatic recurrence (hazard ratio, 1.77; 95% CI, 1.01-3.11; P = .048).

Conclusions

EGFRmu patients have distinct clinical characteristics and potentially better long-term survival, suggesting a need for tailored strategies in screening, research, and treatment.

背景：一系列病例表明，表皮生长因子受体突变型（EGFRmu）和野生型（EGFRwt）肺癌患者术后的长期生存率相当。我们的目的是分析接受手术的I-III期腺癌患者的经验，假设相似的长期生存率。方法对2733例肺叶切除术（2013-2023年）中578例腺癌患者进行完全突变分析。排除IV期疾病和EGFR检测不充分。对112例EGFRmu和466例EGFRwt患者进行基线特征比较，并分析生存趋势和预后因素。结果segfrmu患者多为女性（P < .001）、从不吸烟（P < .001）、一期疾病（P < .001）。EGFRmu患者有更好的5年和10年生存率（55% vs 25%, P < 0.001），这可能反映了基线差异。多变量分析确定肿瘤分期、年龄、男性性别和EGFRwt是死亡率的预测因子。EGFRmu患者的3年无病生存率高于EGFRwt患者（75% vs 58%, P = 0.003）。在多变量分析中，EGFRwt状态不能预测无转移复发的5年死亡率（风险比，1.05;95% CI, 0.44-2.51; P = 0.92），但与转移复发后死亡风险增加显著相关（风险比，1.77;95% CI, 1.01-3.11; P = 0.048）。结论segfrmu患者具有明显的临床特征和更好的长期生存潜力，提示在筛查、研究和治疗方面需要量身定制的策略。

Epstein-Barr Virus–Associated Smooth Muscle Tumor of the Bronchus After Peripheral Blood Stem Cell Transplantation 外周血干细胞移植后支气管发生Epstein-Barr病毒相关平滑肌肿瘤

Annals of thoracic surgery short reports

Epstein-Barr virus (EBV)–associated smooth muscle tumors (SMTs) are rare mesenchymal neoplasms that typically develop in patients with congenital or acquired immunodeficiency and after solid organ transplantation. However, their occurrence after hematopoietic stem cell transplantation has rarely been reported. Furthermore, EBV-SMTs appear as multifocal tumors that can be manifested in a range of anatomic locations. Here, we present a case of successful excision of an EBV-SMT in the proximal bronchus by complex segmentectomy after partial hepatectomy for a liver lesion. Given the recurrence risk of EBV-SMTs, segmentectomy was identified as a successful surgical procedure for preserving pulmonary function.

eb病毒（EBV）相关的平滑肌肿瘤（smt）是罕见的间充质肿瘤，通常发生在先天性或获得性免疫缺陷患者和实体器官移植后。然而，在造血干细胞移植后出现这种情况的报道很少。此外，ebv - smt表现为多灶性肿瘤，可以在一系列解剖部位表现出来。在这里，我们提出一个病例成功切除EBV-SMT近端支气管的复杂节段切除术后，部分肝切除术为肝脏病变。考虑到ebv - smt的复发风险，节段切除术被认为是一种成功的保留肺功能的手术方法。

Background

To determine whether previous coronary artery bypass grafting (CABG) is a risk factor for postoperative mortality, morbidity, or worse quality metrics in patients undergoing left upper lobectomy.

Methods

Using International Classification of Diseases 10th revision codes, the Healthcare Cost and Utilization Project Nationwide Readmissions Database was queried for patients with pulmonary neoplasms undergoing left upper lobectomy from 2016 to 2018 and categorized by history of CABG. Sociodemographic factors, comorbidities, and hospital characteristics were analyzed using univariable and multivariable regressions.

Results

A total of 11,118 patients met inclusion criteria, of whom 465 (4.2%) had a history of CABG. On bivariate analysis, postoperative myocardial infarction and atrial fibrillation rates were higher (P < .004) in patients with prior CABG. However, multivariable modeling revealed no association between history of CABG and worse outcomes across all metrics: in-hospital mortality (odds ratio [OR], 0.806; P = .563), cardiovascular complications (OR, 0.826; P = .0985), pulmonary complications (OR, 0.849; P = .154), length of stay (relative risk, 0.982; P = .619), 30-day readmission (OR, 1.057; P = .747), and 90-day readmission (OR, 1.137; P = .396). Thoracotomy patients experienced worse outcomes across all metrics (P < .05) compared with thoracoscopy. Prior CABG was not associated with worse outcomes in either thoracoscopy or thoracotomy subgroup analyses. Although not statistically significant (P = .255), patients with previous CABG had approximately $6500 in additional charges.

Conclusions

Prior CABG in patients undergoing left upper lobectomy is not associated with increased mortality, morbidity, length of stay, readmissions, or increased hospital charges. Thoracoscopy may be preferred in this population and is associated with improved outcomes compared with thoracotomy.

背景：确定先前的冠状动脉旁路移植术（CABG）是否是左上叶切除术患者术后死亡率、发病率或更差质量指标的危险因素。方法使用《国际疾病分类》第10版修订代码，查询2016 - 2018年行左上肺叶切除术的肺肿瘤患者，并按CABG病史进行分类。使用单变量和多变量回归分析社会人口学因素、合并症和医院特征。结果11,118例患者符合纳入标准，其中465例（4.2%）有冠脉搭桥病史。双因素分析显示，既往冠脉搭桥患者术后心肌梗死和房颤发生率较高（P < 0.004）。然而，多变量建模显示，在所有指标中，冠状动脉搭桥史与较差结局之间没有关联：住院死亡率（优势比[OR]， 0.806; P = 0.563）、心血管并发症（优势比[OR]， 0.826; P = 0.985）、肺部并发症（优势比[OR]， 0.849; P = 0.154）、住院时间（相对风险，0.982;P = 0.619）、30天再入院（优势比，1.057;P = 0.747）和90天再入院（优势比，1.137;P = 0.396）。与胸腔镜相比，开胸手术患者在所有指标上的预后都更差（P < 0.05）。在胸腔镜或开胸亚组分析中，既往CABG与较差的结果无关。虽然没有统计学意义（P = 0.255），但既往CABG患者的额外费用约为6500美元。结论：左上肺叶切除术患者术前CABG与死亡率、发病率、住院时间、再入院率或住院费用增加无关。在这一人群中，胸腔镜可能是首选，与开胸手术相比，胸腔镜能改善预后。

ProtekDuo in Lung Transplant Candidates: Insights From a Single-Center Study of Cases ProtekDuo在肺移植候选者中的应用：来自单中心病例研究的见解

Annals of thoracic surgery short reports

Pub Date : 2026-03-01 Epub Date: 2025-10-08 DOI: 10.1016/j.atssr.2025.09.011

Background

Right ventricular dysfunction often complicates severe lung disease or arises in patients on venovenous extracorporeal membrane oxygenation. Hemodynamic instability can disqualify patients awaiting lung transplant (LT). The ProtekDuo cannula, a dual-lumen device, offers simultaneous right ventricle support and oxygenation when connected to an in-line oxygenator.

Methods

This single-center retrospective study reviewed patients bridged to LT with a ProtekDuo cannula between June 14, 2021, and January 25, 2024.

Results

ProtekDuo was used in 9 patients, in 6 as a bridge to decision and in 3 as a bridge to transplant. It was the initial support in 5 patients; the rest transitioned from venovenous extracorporeal membrane oxygenation because of right ventricular failure (median, 11 days; interquartile range, 7.5-24 days). Of 7 patients listed for LT, 3 underwent LT; 1 patient was successfully bridged with ProtekDuo alone, whereas 2 patients required alternative support because of complications before LT.

Conclusions

Matching patients with optimal mechanical support remains critical, especially given the high mortality of patients on extracorporeal life support on the LT waitlist. Although the ProtekDuo offers dual organ support, further investigation is needed to establish its role as a bridging strategy.

背景：右心室功能障碍常并发严重肺部疾病，或在静脉-静脉体外膜氧合患者中出现。血流动力学不稳定可使等待肺移植（LT）的患者丧失资格。ProtekDuo套管是一种双腔装置，当连接到在线充氧器时，可以同时提供右心室支持和充氧。方法本单中心回顾性研究回顾了2021年6月14日至2024年1月25日期间使用ProtekDuo套管桥接至LT的患者。结果9例患者使用protekduo， 6例作为决定的桥梁，3例作为移植的桥梁。这是5例患者的初始支持；其余患者因右心衰而从静脉-静脉体外膜氧合过渡（中位数为11天；四分位数范围为7.5-24天）。在7例肝移植患者中，3例接受了肝移植；1例患者单独使用ProtekDuo成功桥接，而2例患者在LT前由于并发症需要替代支持。结论为患者匹配最佳机械支持仍然至关重要，特别是考虑到LT等待名单中体外生命支持患者的高死亡率。虽然ProtekDuo提供双器官支持，但需要进一步研究以确定其作为桥接策略的作用。

Purpose

To evaluate the feasibility and safety of internal thoracic artery (ITA) harvesting using water jet (WJ) technology.

Description

The ERBEJET 2 (Erbe) hydrosurgical system was used to harvest ITAs in a skeletonized fashion. The device settings were optimized at 30 bar for selective tissue dissection while preserving vessels.

Evaluation

Bilateral ITAs were harvested from 2 swine using WJ on one side and electrocautery on the other. Tissue samples (WJ n = 19, electrocautery n = 25) were histologically evaluated for coagulation (graded 0-4) and hemorrhage (graded 0-3). Coagulation was less frequent in the WJ group (26.3% vs 96.0%, P < .01) with lower grades (0.42 ± 0.77 vs 2.44 ± 0.82, P < .01). Hemorrhage occurred in all samples but was less severe in the WJ group (1.11 ± 0.32 vs 1.88 ± 0.97, P < .01). No thermal injuries were observed in either group.

Conclusions

WJ harvesting of ITAs demonstrated less tissue damage compared with electrocautery, suggesting its potential as an alternative approach.

目的评价利用水射流技术采集胸内动脉的可行性和安全性。ERBEJET 2 （Erbe）水外科系统用于以骨架方式收获ita。设备设置在30 bar下进行优化，以便在保留血管的同时进行选择性组织剥离。对2头猪进行双侧肿瘤采集，一侧采用WJ法，另一侧采用电灼法。组织样本（WJ n = 19，电灼n = 25）进行组织学评估，以确定凝血（0-4级）和出血（0-3级）。WJ组凝血发生率较低（26.3% vs 96.0%, P < 01），分级较低（0.42±0.77 vs 2.44±0.82,P < 01）。所有样本均发生出血，但WJ组出血较轻（1.11±0.32 vs 1.88±0.97,P < 0.01）。两组均未见热损伤。结论与电灼法相比，swj获取ita的组织损伤更小，提示其作为一种替代方法的潜力。
