Effects of lobectomy in stage II/IIIA second primary lung cancer patients with prior non-small cell lung cancer: a SEER-based study
ConclusionsOur study identified nine independent prognostic factors of Stage II/IIIA second primary lung cancer. Surgery can provide a better prognosis, and lobectomy might be the optimal surgical procedure for these patients. (Source: General Thoracic and Cardiovascular Surgery)

Advances and safe use of energy devices in lung cancer surgery
ConclusionsUnderstanding energy devices could help us use them in a more effective and safer manner. Knowledge of their selection criteria (suitability), merits, risks, and safety precautions relevant to each process of lung cancer surgery could guide appropriate selection.

A valuable echocardiographic indicator for the optimal tightness of bilateral pulmonary artery banding
ConclusionsOur clinical outcomes are satisfactory with low early mortality and a low rate of re-BPAB. The EDV to PSV ratio can be a reliable indicator to assess flow distribution to each lung and may be a valuable adjunct to achieve balanced systemic to pulmonary flow.

Relationships between coronary arteries and atrioventricular annuli: surgical and percutaneous implications
ConclusionsZones at risk of coronary damage were identified on the mitral and the tricuspid annuli between “7:30” and “10:00”, and between “1:30” and “3:00”, respectively. Knowing them can help interventionists avoid ischemic complications. Based on an innovative clock-face orientation scheme in which the distance data were collected at multiple reference points on a superimposed template , our study provides an intuitive and detailed overview of the critical distances between valves and arteries.

Type A aortic dissection with left coronary malperfusion
AbstractLeft coronary artery malperfusion is a fatal complication of acute type A aortic dissection. However, effective treatment strategies have not yet been established. Herein, we report two cases of left coronary artery malperfusion successfully treated with different preoperative catheter interventions, followed by a central aortic repair. Preoperative coronary intervention ensuring the blood flow to the left coronary artery might be essential if a coronary angiogram was performed prior to the diagnosis and treatment.

Single-stage repair of the right aortic arch with Kommerell diverticulum through the right thoracotomy with SIRC approach

Tetralogy of Fallot with severe ascending aortic enlargement in early childhood
We report a rare case of TOF with pulmonary atresia complicated by severe enlargement of the ascending aorta in a girl aged 2 years and 5 months. We performed the Rastelli procedure with ascending aorta replacement. Pathological findings of the ascending aorta included fragmentation of elastic fibers and loss of smooth muscle cells. Postoperatively, the patient remained healthy and asymptomatic. This case indicates that ascending aortic enlargement in conotruncal anomalies may be associated with pathological lesion even in early childhood . Replacement of the diseased aorta could be considered as a concomitant proc...

Enteric-type thymic adenocarcinoma: a case report and literature review focusing on prognosis based on histological subtypes
We report a resected case of a non-mucinous, enteric-type thymic adenocarcinoma in a 53-year-old woman. The operation was performed by median sternotomy, and the tumor was stage II in the Masaoka classification. Six months after the operation, recurrence-free follow-up is currently underway. Knowledge of enteric-type thymic adenocarcinoma can prevent misdiagnosis of metastatic tumors. We also determined the prognosis of enteric-type thymic adenocarcinoma based on histological subtypes through our literature review. (Source: General Thoracic and Cardiovascular Surgery)

Basal segment deep wedge resection for lung cancer with pulmonary fibrosis
AbstractAcute exacerbation (AE) of idiopathic pulmonary fibrosis (IPF) is among the most fatal postoperative complications of lung resection in patients with IPF. Non-small-cell lung cancer (NSCLC) with IPF exhibits basal segment dominance. Treatment options for these lesions include lobectomy or basal segment segmentectomies. However, these procedures potentially increase risks of AE due to surgical stress including prolonged operative time and loss of pulmonary function. Therefore, as an alternative to these procedures, we developed a simple and practical deep wedge resection technique for basal segments. Our technique i...

Extensive aortic root endocarditis caused ventricular septal rupture
AbstractA 79-year-old man was referred to us for severe cardiac decompensation. Chest radiography showed severe pulmonary edema, and transesophageal echocardiography revealed extensive vegetations on all aortic valve leaflets with severe aortic valve regurgitation, heterogeneous cavities adjacent to the aortic annulus, and ventricular septal rupture into the right-ventricular outflow tract. After extensive debridement of the aortic root (including the infected ventricular septum), the ventricular septum and aortic root were reconstructed using autologous and bovine pericardial patches, and a bioprosthetic stented valve was...

Intraoperative margin assessment by wireless signals in thoracoscopic anterior (S3) segmentectomy using a radiofrequency identification marker
AbstractDespite the use of near-infrared thoracoscopy with intravenous indocyanine green, intraoperative assessment of the surgical margin for the resection of non-palpable tumors located near the intersegmental plane requires highly advanced surgical skill for the prevention of local recurrence. Because the demarcation line is limited to the pleural surface, to overcome uncertainty in tumor palpation for deeply located small-sized lesions, other supplemental localization techniques have been proposed. Here, we present a novel surgical technique using radiofrequency identification markers for intraoperative assessment of t...

Successful lung transplant cases with ex vivo lung perfusion assessment of extended criteria donor lungs
We report our successful experience in two lung transplant cases in which ex vivo lung perfusion (EVLP) was used to evaluate the function of injured brain-dead donor lungs that were otherwise initially unacceptable. After the donor ’s lungs were declined for transplantation by all other transplant centers, the lungs were offered to the patients listed for lung transplantation in our hospital. The donor lung function was considered acceptable for transplantation after the 3-h EVLP assessment. In the first case, a 32-year-old man with bronchiolitis obliterans after hematopoietic stem cell transplantation underwent hybrid l...

High-grade tumor classified by new system is a prognostic predictor in resected lung adenocarcinoma
ConclusionsThe prognostic significance of IASLC Grade 3 tumors on recurrence-free probability was confirmed through both univariate and multivariate analyses. Thus, the IASLC Grade 3 tumor is an independent factor of poor prognosis in patients with resected lung adenocarcinoma. (Source: General Thoracic and Cardiovascular Surgery)
