Mitral valve repair for endocarditis in an acute setting is still challenging due to difficulties in debriding friable tissue and in leaving enough non-infected tissue for reconstruction. Endoscopic approaches for complex mitral valve procedures via a minimally invasive approach have been reported from high-volume programs. However, the role of endoscopic mitral valve surgery for acute infective endocarditis has not been clearly defined. We report our technique of endoscopic mitral valve repair using the cavitron ultrasonic surgical aspirator system for active endocarditis. The cavitron ultrasonic surgical aspirator with a low power setting provides enough debridement of the infective tissue and leaves healthy tissue adequate for repair under a totally endoscopic vision.

由于清除易碎组织和留下足够的非感染组织进行重建的困难,急性心内膜炎的二尖瓣修复仍然具有挑战性。经微创入路进行复杂二尖瓣手术的内镜入路已在大量项目中得到报道。然而,内窥镜二尖瓣手术在急性感染性心内膜炎中的作用尚未明确界定。我们报告我们的技术,内窥镜下修复二尖瓣使用腔腔超声手术吸引系统对活动性心内膜炎。低功率设置的腔室超声手术吸引器提供足够的感染组织清创,并在完全内窥镜视野下留下足够的健康组织进行修复。

Although the diagnosis of malignant pleural mesothelioma at an in situ stage was traditionally challenging, it is now possible owing to advances in molecular biological methods such as P16 fluorescence in situ hybridization or BRCA1-associated protein 1 immunohistochemistry. Here, we report the first case, to our knowledge, of total parietal pleurectomy for mesothelioma in situ. Future follow-up and accumulation of cases are necessary to determine whether total parietal pleurectomy could be applied as a treatment for mesothelioma in situ or not.

尽管恶性胸膜间皮瘤在原位阶段的诊断传统上具有挑战性,但由于分子生物学方法的进步,如P16荧光原位杂交或brca1相关蛋白1免疫组织化学,现在可以进行诊断。在这里,我们报告第一个病例,据我们所知,全胸膜壁切除原位间皮瘤。胸膜壁全切除术是否可以作为原位间皮瘤的治疗方法,需要进一步的随访和病例积累来确定。

Objectives: We applied high-flow regional cerebral perfusion (HFRCP) for aortic arch reconstruction in neonates and infants by monitoring regional oxygen saturation of the thigh (rSO2T) using near-infrared spectroscopy to maintain peripheral perfusion. This study was designed to investigate the optimal perfusion flow of HFRCP for renal protection.

Methods: From 2009 to 2021, 28 consecutive neonates and infants who underwent aortic arch reconstruction with HFRCP were enrolled. The median age of the patients was 27 days; the median body weight was 3.0 kg. In HFRCP, perfusion flow was targeted at approximately 80-100 mL/kg/min and then lowered corresponding to brain rSO2 levels and blood gas data. Isosorbide dinitrate and chlorpromazine were administered to enhance peripheral perfusion flow. Regional oxygen saturation of the forehead and thighs were monitored. The stage of acute kidney injury (AKI) was classified based on the Kidney Disease Improving Global Outcomes criteria.

Results: No patients had neurological events and peritoneal dialysis after surgery. The incidence of AKI was 39.3% with only three patients having greater than stage 2 AKI. The maximum postoperative serum creatinine concentration was negatively associated with the lowest rSO2T during HFRCP. The rSO2T during HFRCP was a predictive factor for postoperative creatinine increase of ≧0.3 mg/dL. The area under receiver operating characteristic curve was 0.78 with the cutoff value of 48% for rSO2T.

Conclusions: The rSO2T during HFRCP is a potential predictor of postoperative renal function. To prevent AKI, the rSO2T should be preserved more than 48% by increasing HFRCP flow.

目的:我们将高流量区域脑灌注(HFRCP)应用于新生儿和婴儿的主动脉弓重建,通过使用近红外光谱监测大腿区域血氧饱和度(rSO2T)来维持外周灌注。本研究旨在探讨 HFRCP 保护肾脏的最佳灌注流量:方法:从 2009 年到 2021 年,连续 28 名新生儿和婴儿接受了 HFRCP 主动脉弓重建术。患者的中位年龄为 27 天,中位体重为 3.0 千克。在 HFRCP 中,灌注流量的目标值约为 80-100 mL/kg/min,然后根据脑部 rSO2 水平和血气数据降低灌注流量。使用二硝酸异山梨酯和氯丙嗪来增强外周灌注流量。对前额和大腿的区域血氧饱和度进行了监测。急性肾损伤(AKI)的分期是根据肾病改善全球结果标准划分的:结果:术后没有患者发生神经系统事件和腹膜透析。AKI发生率为39.3%,只有3名患者的AKI超过2期。术后最高血清肌酐浓度与 HFRCP 期间的最低 rSO2T 呈负相关。HFRCP 期间的 rSO2T 是术后肌酐升高≧0.3 mg/dL 的预测因素。rSO2T的临界值为48%时,接收者操作特征曲线下面积为0.78:结论:HFRCP期间的rSO2T是术后肾功能的潜在预测指标。为预防 AKI,应通过增加 HFRCP 流量将 rSO2T 保持在 48% 以上。

Objectives: Air leakage after lung resection is a common morbidity that may lengthen hospital stay. Applying sealant to a lesion is an effective prophylaxis in clinical practice. This study aimed to examine the effect of a combination of a bioabsorbable polyglycolic acid (PGA) fabric and fibrin glue (FG) on air sealing by measuring the in vitro mechanical strength and degradation of the fabric, and in vivo histological changes after implantation.

Methods: A defect was created in the canine left upper lung lobe, and then filled with a fibrinogen solution and covered with a PGA sheet spray-coated with fibrinogen and thrombin. After 1 and 4 weeks, air leakage from the lesion was examined in vivo under airway pressure. Tissue samples were harvested for histological assessment.

Results: The mechanical strength of the PGA fabric remained at 80-90% of the baseline level for 1 week in phosphate-buffered saline, and then rapidly decreased to zero thereafter. Air leakage from the lung defect was prevented by the combination of PGA fabric and FG at 1 and 4 weeks. Histological examinations showed that PGA bundles persisted with a non-specific inflammatory response for 2 weeks and then gradually broke into sparse yarns surrounded by collagen fibres and capillaries by 8 weeks. The lung defect was filled with FG at 1 week and by granulation tissue thereafter.

Conclusions: These results provide evidence for the efficacy of a combination of PGA fabric and FG for the prevention of air leakage in the critical period after lung surgery.

目的:肺切除术后漏气是一种常见的并发症,可延长住院时间。在临床实践中,在患处涂抹密封胶是一种有效的预防措施。本研究旨在通过测定生物可吸收聚乙醇酸(PGA)织物和纤维蛋白胶(FG)的体外机械强度和降解,以及植入后的体内组织学变化,研究PGA织物与纤维蛋白胶(FG)的组合对空气密封的影响。方法:在犬左上肺叶处造一个缺损,用纤维蛋白原溶液填充,再用涂有纤维蛋白原和凝血酶的PGA片喷雾覆盖。1周和4周后,在气道压力下检测病灶的漏气情况。收集组织样本进行组织学评估。结果:PGA织物的机械强度在磷酸盐缓冲盐水中1周保持在基线水平的80-90%,之后迅速降至零。在第1周和第4周,PGA织物和FG联合使用可防止肺缺损漏气。组织学检查显示PGA束持续出现非特异性炎症反应2周,8周时逐渐破裂成稀疏的纱线,周围有胶原纤维和毛细血管。肺缺损在第1周被FG填充,之后被肉芽组织填充。结论:本研究结果为PGA织物与FG复合用于肺术后关键时期预防漏气提供了依据。

Objectives: Sickle-cell disease (SCD) patients are considered to be at high risk from open-heart surgery. This study assessed the role of a simple sickling-prevention protocol.

Methods: Perioperative non-specific and SCD-specific morbidity and 30-day mortality are investigated in a retrospective cohort study on patients undergoing isolated mitral valve surgery. Patients with and without SCD were compared. In the SCD cohort, a bundle of interventions was applied to limit the risk of sickling: 'on-demand' transfusions to keep haemoglobin levels of around 7-8 g/dl, cardiopulmonary bypass (CPB) with higher blood flow and perfusion temperature, close monitoring of acid-base balance and oxygenation.

Results: Twenty patients with and 40 patients without SCD were included. At baseline, only preoperative haemoglobin levels differed between cohorts (8.1 vs 11.8 g/dl, P < 0.001). Solely SCD patients received preoperative transfusions (45.0%). Intraoperative transfusions were significantly larger in SCD patients during CPB (priming: 300 vs 200 ml; entire length: 600 vs 300 ml and 20 vs 10 ml/kg). SCD patients had higher perfusion temperatures during CPB (34.7 vs 33.0°C, P = 0.01) with consequently higher pharyngeal temperature, both during cooling (34.1 vs 32.3°C, P = 0.02) and rewarming (36.5 vs 36.2°C, P = 0.02). No mortality occurred, and non-SCD-specific complications were comparable between groups, but one SCD patient suffered from perioperative cerebrovascular accident with seizures, and another had evident haemolysis.

Conclusions: SCD patients may undergo open-heart surgery for mitral valve procedures with an acceptable risk profile. Simple but thoughtful perioperative management, embracing 'on-demand' transfusions and less-aggressive CPB cooling is feasible and probably efficacious.

目的:镰状细胞病(SCD)患者被认为是开胸手术的高危人群。本研究评估了简单的镰状病预防方案的作用。方法:回顾性队列研究分离二尖瓣手术患者围手术期非特异性和scd特异性发病率和30天死亡率。比较有无SCD患者。在SCD队列中,应用了一系列干预措施来限制镰状病变的风险:“按需”输血以保持血红蛋白水平在7-8 g/dl左右,体外循环(CPB)具有更高的血流量和灌注温度,密切监测酸碱平衡和氧合。结果:纳入有SCD患者20例,无SCD患者40例。在基线时,只有术前血红蛋白水平在队列之间存在差异(8.1 g/dl vs 11.8 g/dl, P)。结论:SCD患者可以在可接受的风险情况下接受二尖瓣手术。简单但周到的围手术期管理,包括“按需”输血和低侵略性CPB冷却是可行的,可能是有效的。

Severe acute ischaemic stroke early after wedge resection is very rare in healthy middle-aged patients. Here, we reviewed the data and characteristics of 9 cases. The infarction resulted from embolism in intracranial arteries, severely impacting the quality of life. In the first 2 patients, the onset symptom was confused with residual anaesthetic effects early after surgery. Drawing from the initial 2 cases, the following 7 patients received accurate diagnosis and emergent endovascular thrombus aspiration with good outcome due to immediate reperfusion. Furthermore, we discuss the principal causes of severe acute stroke in healthy middle-aged patients and the efficacy of endovascular thrombus aspiration.

在健康的中年患者中,楔形切除后早期发生严重的急性缺血性卒中是非常罕见的。在这里,我们回顾了9例病例的资料和特征。梗死是由颅内动脉栓塞引起的,严重影响患者的生活质量。在前2例患者中,发病症状与术后早期残留麻醉效应相混淆。从最初的2例病例中,以下7例患者得到了准确的诊断和急诊血管内血栓抽吸,由于立即再灌注,结果良好。此外,我们还讨论了健康中年患者严重急性脑卒中的主要原因和血管内血栓抽吸的疗效。

Although there have been a few case reports of pulmonary sequestration, it is primarily located in the lower lobe and left lung, rarely in the right upper lobe. Here, we report a case presented with haemoptysis. Computed tomography images revealed flake ground-glass shadows in the right upper lobe. Computed tomography angiography demonstrated an artery supplied the affected lesions stemmed from the aortic arch. We diagnosed and treated her with bronchial artery angiography with coil embolization. No complications were found after operation until now. Thus, CTA could help identify the abnormal blood vessels, and interventional therapy may be an effective alternative to surgery of pulmonary sequestration.

虽然有少数肺隔离的病例报道,但它主要位于肺下叶和左肺,很少发生在右肺上叶。在此,我们报告一例咯血。计算机断层扫描图像显示右上叶片状磨玻璃影。计算机断层血管造影显示一条动脉供应病变源于主动脉弓。我们对她进行了诊断和治疗,支气管动脉血管造影和线圈栓塞。术后未见并发症。因此,CTA可以帮助识别异常血管,介入治疗可能是肺隔离手术的有效替代方法。

their about our recently published study. Annular stabilization is the main concern of cardiac surgeons for long-term durability of transapical neochords implantation (NC) due to our well-established surgical technique. Transcatheter edge-to-edge mitral repair is always done with no annular stabilization but apparently, this is not seen as a major concern among interventional cardiologists who have demonstrated to be perseverant and keep on expanding indications and performing trials (REPAIR MR ClinicalTrials.gov and PRIMARY ClinicalTrials.gov Identifier: As a matter of fact, so far data do not support the lack of mitral annulus stabilization as a potential cause of NC failure. In entire experience with transapical-NC [1], failure has never been related to mitral annular enlargement. Furthermore, it has demonstrated that annular remodelling (reduction of annular di- ameter) occurs in patients undergoing this procedure [2]. Early referral and consequently early treatment of patients with degenerative mitral regurgita- tion (DMR) is likely going to reduce the need for annular stabilization. It is true that conventional surgery for DMR provides optimal results in terms of mortality and complications as well as of freedom from recurrent mitral regurgitation (MR) in centres of excellence that are dedicated and highly commit- ted to this procedure [3] but the real world is a different thing [3, 4]. Our data show no statistical differences between conventional surgery and NC at follow-up in patients with type A anatomy in terms of recurrence of moderate MR (63.9% vs 74.6%), severe MR (79.3% vs 79%)
