General Thoracic and Cardiovascular Surgery

BACKGROUND: Thoracic endometriosis syndrome gives rise to various clinical and radiological manifestations. We reviewed the records of patients operated for intrathoracic migration of abdominal viscera through a diaphragmatic hernia secondary to thoracic endometriosis. METHODS: We retrospectively reviewed the single-center prospective collected database of all patients operated for thoracic endometriosis during the twenty years. All cases in which an abdominal organ was found to be herniated into the thoracic cavity were retrieved...

OBJECTIVES: Transaxillary access is the most popular alternative to transfemoral transcatheter aortic valve replacement. Although left transaxillary access is generally preferred, right transaxillary transcatheter aortic valve replacement could be challenging because of the opposing axillary artery and aortic curvatures, which may warrant procedural modifications to improve alignment. Our aim is to compare our single center's outcomes for left and right transaxillary access groups and to evaluate procedural modifications for facilitating right transaxillary transcatheter aortic valve replacement...

OBJECTIVES: This study analyzed the long-term survival of dialysis patients undergoing AVR using the Japanese National Clinical Database with additional survival data. METHODS: De-novo AVR for dialysis-dependent patients between 2010 and 2012 who were registered in the Japan Cardiovascular Surgery Database were included. Concomitant aortic surgery and transcatheter aortic valve replacement were excluded. An additional questionnaire was sent to each hospital regarding the underlying kidney disease, the duration of dialysis initiation to the surgery, and clinical outcomes...

BACKGROUND: Malfunctions of robotic instruments during robotic surgery are well known to occur; however, detailed reports on the inherent problems associated with robotic instruments and robotic surgical systems are scarce. The objective of this study was to retrospectively investigate the intraoperative problems associated with robotic surgical systems and robotic instruments. MATERIALS AND METHODS: This was a single-center retrospective study. Between April 2012 and December 2022, 544 patients with consecutive lung malignancies and/or mediastinal tumors underwent robot-assisted thoracoscopic surgery...

In the case of mitral repair with severe aortic regurgitation, aortotomy and selective cardioplegia are necessary for myocardiac protection. In this situation, the saline test for mitral valve repair cannot be accomplished due to incomplete left ventricular filing. In patients undergoing mitral valve repair concomitant with severe aortic valve insufficiency, after cardiac stand still was achieved by selective cardioplegia. Each center of the aortic leaflet, termed the node of Arantius, was stitch up using a 5-0 polypropylene suture, forming a clover leaflet shape...

OBJECTIVE: To assess the occurrence, predictors, and outcomes of hypo-attenuated leaflet thickening (HALT) and thrombus outside the prosthetic valve following surgical aortic valve replacement. METHODS: A total of 118 patients underwent surgical aortic valve replacement with bioprosthetic valves between July 2020 and June 2022. Sixty-two (52.5%) patients, which is a fairly high number of patients, underwent cardiac computed tomography and transthoracic echocardiography one week after surgery...

BACKGROUND: Immediate surgery to save life is the recommended treatment for Stanford type A acute aortic dissection (AAAD). METHOD: The present study comprised 35 patients admitted with AAAD who were considered inappropriate candidates for surgery or declined surgery. The mean age was 84.5 ± 9.6 years. Eight patients who were considered inappropriate candidates for surgery due to severe stroke in 2 patients or hemodynamic instability in 6...

OBJECTIVE: To establish a risk-stratification system for predicting the postoperative recurrence of esophageal squamous cell carcinoma, this study aimed to evaluate the prognostic value of clusters based on blood inflammation and coagulation markers and investigate their correlation with serum cytokines and genetic alteration. METHOD: This single-center, retrospective cohort study enrolled 491 patients with esophageal cancer who underwent subtotal esophagectomy between 2004 and 2012...

OBJECTIVE: Degenerative aortic stenosis and coronary artery disease are considered to be the most prevalent cardiovascular diseases in industrialized countries. This study aims to determine the change over time in von Willebrand factor antigen, von Willebrand factor activity, and factor VIII and where there is a correlation with total post-operative drainage. METHODS: The single-center retrospective study included 203 consecutive patients (64.5% male), undergoing coronary artery bypass surgery between March 1, 2019 and June 30, 2020 at the University Clinical Center of Serbia in the Clinic for Cardiac Surgery in Belgrade, Serbia...

Acute type A aortic dissection may originate from a primary intimal tear located in the ascending aorta and often extends retrogradely into the aortic root. How to prevent bleeding in the aortic root and eliminate false lumen is very important in aortic dissection. We have developed a modified anastomotic technique that involves inverting adventitial and graft into aorta and reinforcing with a felt strip on the external border of the aortic wall. Since 2020, 45 consecutive patients with type A aortic coarctation have undergone this aortic root reconstruction procedure, to date, none have been reopened for bleeding or remnant dissection...

OBJECTIVE: Considering the controversial benefits of video-assisted thoracoscopic surgery (VATS), we intended to evaluate the impact of surgical approach on cardiac function after lung resection using myocardial work analysis. METHODS: Echocardiographic data of 48 patients (25 thoracotomy vs. 23 VATS) were retrospectively analyzed. All patients underwent transthoracic echocardiography (TTE) within 2 weeks before and after surgery, including two-dimensional speckle tracking and tissue Doppler imaging...

OBJECTIVES: Body composition and systemic inflammation/nutrition have been identified as important clinical factors in cancer patients. The modified advanced lung cancer inflammation index (mALI), which combines body composition and systemic inflammation/nutrition, is defined as appendicular skeletal muscle index × serum albumin/neutrophil-lymphocyte ratio. This retrospective study aimed to investigate associations between preoperative mALI and surgical outcomes in non-small cell lung cancer (NSCLC) patients...

BACKGROUND: The manubrium and body of the sternum are connected by the manubrium-sternum joint (MSJ). In performing the Nuss procedure for pectus excavatum patients, the body of the sternum is elevated as the operator flips correction bars upside down. Theoretically, the presence of the MSJ should allow elevation of the sternum body. However, does the MSJ secure sufficient elevation of the sternum? This study aims to elucidate this clinical question. METHODS: Seventy-four adult pectus excavatum patients with moderate to serious deformity (with Haller Index being equal to or greater than 5) were included in the study...

OBJECTIVES: We introduced the use of an upper partial sternal split for pediatric cardiac surgical procedures in our unit in 2016. We report the outcomes of our experience in 51 patients using this approach. METHODS: From February 2016 to September 2022, 51 patients underwent congenital cardiac surgical procedures using an upper partial sternal split including vascular ring repair (n = 20), subaortic membrane (n = 12), ventricular septal defect closure with aortic valve resuspension (n = 9), aortic arch repair (n = 4), pulmonary artery band (n = 2), pulmonary artery sling (n = 1), supravalvular aortic stenosis (n = 1), aortic valve replacement (n = 1), and pulmonary artery plasty (n = 1)...

OBJECTIVE: A chest tube is usually placed in patients undergoing general thoracic surgery. Although the barbed suture method has been introduced for chest tube wound closure, its superiority to the conventional suture methods for drain management remains unclear. The study aimed to determine whether the barbed suture method could reduce drain-related adverse events compared to the conventional method. METHODS: We retrospectively reviewed the medical records of patients who underwent general thoracic surgery between January 2021 and December 2022, 1 year before and after the introduction of the barbed suture method at our institution...
