Intravenous indocyanine green (ICG) has been reported to localize intra-abdominal metastatic lesions in several clinical trials. Our pilot study aimed to investigate the feasibility and safety of ICG fluorescence localization in pulmonary metastasectomy using a near-infrared fluorescence thoracoscope. Each patient received intravenous 0.25 or 0.5 mg/kg of ICG. The maximum diameter of the tumor on computed tomography ranged from 0.5 to 3.5 (median: 1.15) cm. Intravenous ICG injection localized pulmonary metastases in a portion (3 patients) of the enrolled patients...

BACKGROUND:  Patients with N1 non-small cell lung cancer represent a heterogeneous population. The aim of this study is to determine the difference of survival rate between subtypes of N1 disease in surgically resected non-small cell lung cancer patients and to compare the survival in these patients with multi-N1 and single N2 (skip metastasis) disease. METHODS:  Patients who underwent anatomical pulmonary resection in our institution between 2007 and 2014 with a pathological diagnosis of N1 and single N2 positive non-small cell lung cancer were included in the study...

BACKGROUND:  In thoracic surgery clinics, patients are encouraged to walk; however, to our knowledge, there is no data regarding the minimum step count necessary to protect them from complications. In our study, we aim to ascertain the relationship between walking and prolonged air leak (PAL), which is one of the most common complications following thoracic surgery. METHODS:  Patients, who were being followed-up at our clinic between December 2016 and July 2017, were separated into three groups and were investigated prospectively...

BACKGROUND:  To minimize the surgical damage, minimally invasive mitral valve surgery (MIMVS) has become the therapy of choice. However, this approach is technically more challenging, especially in endocarditis. The data on MIMVS in endocarditis are scarce, we therefore retrospectively analyzed the result at our institute. METHODS:  From January 2011 and July 2017, 420 MIMVS were performed, out of which 44 (10%) were for endocarditis. Mean age was 55 ± 17 years and 41% ( n  = 18) were male...

BACKGROUND:  Transplant vasculopathy (TV) is the main limiting factor for long-term graft survival characterized by fibrosis, myofibroblast, and smooth muscle cell (SMC) proliferation. Decoy oligodeoxynucleotide (dODN) against the transcription factor activator protein-1 (AP-1) might interfere with the expression of AV-related genes that govern neointima formation. METHODS:  Aortic allografts from DBA/2 mice were incubated with control buffer, consensus, or mutated control AP-1 dODN and were transplanted into the infrarenal aorta of C57BL/6 mice...

BACKGROUND:  Numerous studies have demonstrated a negative impact of prosthesis-patient mismatch (PPM) on long-term clinical outcomes after aortic valve replacement. However, the impact of PPM after mitral valve replacement (MVR) on clinical outcomes is still controversial. This study was conducted to evaluate the impact of PPM on early and long-term survival after MVR. METHODS:  A literature search of five databases was performed. The primary and secondary outcomes were all-cause mortality and early mortality, respectively...

BACKGROUND:  Optimal surgical treatment of functional ischemic mitral regurgitation (FIMR) is still controversy. Due to the underlying pathophysiology, stand-alone ring annuloplasty is assumed with a high recurrence rate of mitral regurgitation, thus additional subvalvular repair techniques might improve the results. This in vitro study introduces a new device for subvalvular mitral valve repair. METHODS:  We developed a new device for subvalvular mitral valve repair, consisting of two frames for papillary muscle (PM) attachment, which are connected with two holding bars serving for fixation of the device on an annuloplasty ring...

INTRODUCTION:  Surgical management for tricuspid valve (TV) endocarditis is usually TV repair or replacement. When repair is not feasible, and concerns for patient recidivism preclude TV replacement, tricuspid valvectomy without replacement is an option to alleviate symptoms and allow time for addiction management. METHODS:  We reviewed our institution's experience with isolated tricuspid valvectomy for cases of intravenous drug use (IVDU)-associated endocarditis ( n  = 7) from 2009 to 2017...

BACKGROUND:  Main prognostic factors of improved survival after pulmonary metastasectomy (PM) for osteogenic and soft tissue sarcomas are suggested as histological type, number and size of pulmonary nodules, and disease-free interval (DFI). METHODS:  Sixty-nine patients who underwent PM between January 1999 and December 2017 were evaluated retrospectively. Relations between parameters and prognostic risk factors for overall survival (OS) and disease-free survival (DFS) were evaluated...

BACKGROUND:  Esophageal gastrointestinal stromal tumors (E-GISTs) represent less than 1% of all GISTs. The rarity of this lesion precludes the realization of randomized studies, and its treatment remains a matter of debate. We aimed to evaluate the feasibility of enucleation by video-assisted thoracic surgery (VATS) for low- to intermediate-risk E-GIST. METHODS:  We performed a retrospective review of patients treated by enucleation through VATS between January 2004 and January 2014 and reviewed the literature...

BACKGROUND:  Ascending aorta or hemi-arch repair are common in the acute phase of type A dissection. Postdissection aneurysms can develop with antegrade perfusion of the false lumen in the dissected aortic arch and require reoperation. METHODS:  From 2012 to 2018, we reoperated nine patients with postdissection aneurysms using a hybrid technique without cardiopulmonary bypass. The patients had a EuroSCORE II of 13% and a logistic EuroSCORE I of 45% and were not candidates for frozen elephant trunk surgery...

We reported the role of endobronchial ultrasound as complement to standard diagnostic exams to better define the benign tracheal stenosis (i.e., thickness and tracheal cartilage integrity) and to plan the treatment with flexible instead of rigid bronchoscope. Under sedation and spontaneous ventilation, the flexible bronchoscope was inserted through the laryngeal mask airway that assured the ventilation. The stenosis was first resected with cold scissors and then dilated with balloon catheter. This strategy was successfully applied in five consecutive patients...

OBJECTIVES:  The increasing proportion of elderly patients in cardiac surgery poses additional challenges for the clinical management and leads to a higher operative risk due to multiple comorbidities of these patients. We reviewed the outcome of patients who were 75 years and older and underwent complex multiple valve surgery at our institution. METHODS:  A retrospective review was performed to identify patients who were 75 years and older and underwent multiple valve surgery between January 2011 and May 2016 at our institution...

BACKGROUND:  Patients receiving arterial grafts have superior late survival after coronary artery bypass graft (CABG) surgery. The aim of our study was to evaluate the mid- and long-term results of total arterial (TA) revascularization in the elderly. METHODS:  Between January 2005 and December 2012, a retrospective study on age-, gender-, and EuroSCORE-matched patients aged 70 years and older was performed. Altogether, 356 patients who received isolated CABG were assigned to either TA group or control (CON) group...

BACKGROUND:  Pectus carinatum (PC) is one of the most common types of congenital chest wall deformity. Recently, noninvasive compressive brace therapy has been more frequently used than invasive surgical correction to treat PC. Hence, the purpose of this study was to determine the long-term outcome of compressive brace therapy. METHODS:  We retrospectively reviewed patients with PC who underwent compressive brace therapy between January 2014 and December 2016...

BACKGROUND:  The incidence of esophageal carcinoma is increasing in the western world, and esophageal resection is the essential therapy. Several studies report advantages of minimally invasive esophagectomies (MIEs) versus conventional open procedures (OPs). The benefits of the use of fully MIE or robot-assisted MIE (RAMIE) compared with the hybrid approaches (laparoscopic gastric preparation and open transthoracic esophagectomy) remain unclear. METHODS:  Between July 2015 and August 2017, the data of 75 patients with esophageal carcinoma were prospectively registered...

OBJECTIVE:  Coronary artery bypass grafting (CABG) using bilateral internal thoracic artery (BITA) is associated with the best long-term survival. However, using BITA increases the risk of sternal wound infections with conventional sternotomy. We describe here our initial results of minimally invasive CABG (MICS-CABG) using BITA. METHODS:  Patients were operated through an incision similar to that of standard minimally invasive direct CABG. All operations were performed off-pump...

BACKGROUND:  Minithoracotomy (MT) has gained broad acceptance for mitral valve surgery (MVS) in the last decade. In the presence of defined limitations of MT, however, full sternotomy (FS) is still widely preferred. We assume that the less investigated partial upper sternotomy (PS) will permit the gap between MT and FS in MVS to be closed. The purpose of this study is to investigate a valid less invasive alternative to MT for isolated MVS or multivalve surgery. METHODS:  This retrospective analysis includes data on 1,639 patients, who underwent either isolated or combined primary MVS at our department from May 2011 to August 2017...
