The transmanubrial approach first reported by Grunenwald in 1997 is well-known for superior sulcus lung malignancies involving the thoracic inlet. Because an anterior approach to levels below Th2 is difficult without removing the manubrium, we used the transmanubrial approach for anterior cervicothoracic corpectomy and fusion (C7-Th3) in a patient with bilateral lower extremity paralysis due to ossification of the posterior longitudinal ligament in the cervicothoracic spine. To ensure more working space in the deep surgical field, which was hindered by a prior cardiac operation with median sternotomy and a goiter protruding into the upper mediastinal region, the right brachiocephalic vein was temporarily divided and subsequently reconstructed using bovine pericardium...

BACKGROUND: The percentage of patients in resectable stages at initial diagnosis of non-small cell lung cancer (NSCLC) raises due to better screening programs. Therefore, risk prediction models are becoming more critical. Here, we validated and compared four established scoring models, the Thoracoscore, Epithor, Eurloung 2, and the simplified Eurolung 2 (2b), in their ability to predict 30-day mortality. METHODS: All consecutive patients undergoing anatomical pulmonary resection were included...

A dual left anterior descending artery (LAD) is not an uncommon anomaly of the coronary arterial system. The earlier classifications by various authors lacked standardization and uniformity and are too complex for clinical usage. Therefore, a new classification in the form of coding system is proposed to facilitate the identification and reporting of the anomaly by the cardiologists to maintain uniformity in reporting, which aids in adequate planning of the revascularization strategies in patients with symptomatic coronary artery disease involving the dual LAD system...

BACKGROUND: This study was aimed at reporting the surgical outcomes and evaluating the safety and feasibility of robotic repair of Morgagni's repair in adults. METHODS: This is a retrospective analysis of seven cases of Morgagni's hernia in adults, managed by robotic method in a tertiary-level thoracic surgery centre over 9 years. A detailed analysis of all perioperative variables including complications was carried out. RESULTS: A total of seven patients underwent Robotic Morgagni's hernia repair during the study period...

BACKGROUND: Endovascular aortic repair (EVAR) has become the mainstay treatment for abdominal aortic aneurysms and is associated with excellent clinical outcomes. However, there remains a risk of complications requiring reintervention. Several EVAR devices exist commercially, yet, the Terumo Aortic Fenestrated Anaconda™ has demonstrated outstanding results. The main scope of this study is to evaluate survival/longevity, target vessel patency (TVP), endograft migration and reintervention following Fenestrated Anaconda™ implantation and discuss relevant literature...

BACKGROUND: Hyperhomocysteinemia is associated with an increased risk for cardiovascular diseases. The influence of hyperhomocysteinemia on post-operative events, after coronary artery bypass surgery graft, is less studied. METHODS: This cross-sectional study aimed to determine if hyperhomocysteinemia was associated with post-operative complications in patients < 50 years who underwent off-pump coronary artery bypass graft for coronary artery disease. A set of major post-operative complications were considered as primary outcome measures...

OBJECTIVE: The aim of this study was to compare efficacy and safety of paravertebral block (PVB) and interpleural analgesia (IPA) after minimally invasive cardiac surgery through thoracotomy in terms of quality of analgesia, post-operative mechanical ventilation time, intensive care unit (ICU) and hospital length of stay (LOS) and complications. DESIGN: A randomized, prospective study. PARTICIPANTS: A total of 50 adult patients (18-50 years old) undergoing minimally invasive cardiac surgery via thoracotomy...

Type Ia endoleaks due to failed sealing or loss of landing zone and the adequate management thereof remain crucial for long-term therapeutic success following TEVAR. This expert opinion summarizes our institutional experience with endovascular, open surgical, and hybrid techniques in the context of recent scientific publications. The rapid turnover of technical innovations, but most importantly outcome data demonstrate the requirement for increasingly patient-tailored treatment strategies and the need for specialized aortic centers...

INTRODUCTION: Effective treatment of patients with ischemic cardiomyopathy (ICM) is one of the most challenging issues in modern cardiac surgery. The aim of this study was to assess the state of cardiomyocytes and myocardial extracellular matrix, as well as to identify informative markers of an unfavorable prognosis for surgical treatment of ICM. MATERIALS AND METHODS: We retrospectively reviewed patients who underwent surgical treatment of ICM between 2011 and 2018 at a single center...

OBJECTIVES: Little is known about the fate of untreated moderate aortic regurgitation after mitral valve replacement for rheumatic heart disease. The aim of this study was to compare the progression to significant aortic valve disease of untreated moderate and mild aortic regurgitation after mitral valve replacement for rheumatic heart disease. METHODS: Among patients who underwent mitral valve replacement for rheumatic heart disease without concomitant aortic valve intervention at our institution between January 2005 and December 2017, we selected 338 patients with pure aortic regurgitation (273 patients with mild and 65 patients with moderate aortic regurgitation)...

BACKGROUND: We investigated the effect of unexpected N2 on survival in stage IIIB/N2 cases. METHODS: We retrospectively analyzed 1803 non-small cell lung cancer patients between 2010 and 2016. There were 89 patients (4.9%) with unexpected N2 (pathological (p) IIIB/N2 group), whereas 49 patients (2.7%) with cN2 (clinical (c) IIIB/N2 group). Although pIIIB/N2 group underwent surgery followed by adjuvant therapy, the cIIIB/N2 group of patients had multimodality treatment including induction chemotherapy ± radiotherapy followed by surgery...

This is the first report of total arch replacement to repair re-coarctation. A 14-year-old boy with hypoplastic left heart syndrome developed re-coarctation, severe stenosis of neck vessels, and right ventricle dysfunction after a Norwood procedure. We performed total arch replacement; the postoperative course was unremarkable. He was followed up until 18 years of age and did not need re-intervention. Using artificial blood vessels in total arch replacement is rarely indicated but can be safely achieved when required...

Circumflex aortic arch is a rare vascular ring anomaly, which is often associated with tracheobronchomalacia. Aortic uncrossing is the definitive repair of this condition, which is a major high-risk operation; therefore, it is not suitable for small patients such as newborn infants or individuals who have severe comorbidities. We present a case of the circumflex aortic arch with tracheobronchomalacia in a 2.7-kg infant who underwent successful innovative combined surgery of the airway and the aorta.

OBJECTIVE: Heart-Lung Transplantation (HLTX) is required both in primary pulmonary hypertension (PPH) and Eisenmenger syndrome (ES) when there is associated end-stage heart disease. Although PPH is associated with an otherwise structurally normal heart, ES is associated with congenital heart defects, which may increase the complexity of the operation. This study analyzes if the diagnosis (PPH vs. ES) is related to short-term outcomes after HLTX. METHODS: Patients ≥18 years of age with PPH and ES who underwent HLTX were identified in the United Network for Organ Sharing database from 2005 to 2021...

Chronic type B aortic dissection with the right aortic arch was rare. We present the case of a 59-year-old man with a right aortic arch and chronic type B aortic dissection, with a maximum size of 80 mm. Graft replacement was successfully performed through right anterolateral thoracotomy with partial sternotomy through the fourth intercostal space. The patient's postoperative course was uneventful. He had no paralysis and was extubated on postoperative day 2 and discharged from the hospital on postoperative day 15...

Left ventricular diverticulum is a rare cardiac abnormality characterised by focal protrusion of the ventricular wall containing all the three layers with synchronous contractility. They have been described more commonly in paediatric patients and may be seen associated with congenital midline thoracoabdominal abnormalities. There are few reports of left ventricular diverticulum in cases of patent ductus arteriosus and coarctation with subaortic diverticula in the bicuspid aortic valve. Here, we report a case of left ventricular diverticulum in association with bicuspid aortic valve and pseudocoarctation in a 53-year-old female patient with a pertinent review of the literature...

BACKGROUND: The advantages of segmentectomy over lobectomy in sparing pulmonary function remain controversial. Lower lobe segmentectomy is divided into simple segmentectomy, such as segment 6; and complex segmentectomy that includes the basal segments. Here, we compared residual lung function after thoracoscopic segmentectomy versus lobectomy in the lower lobe using the three-dimensional computed tomography volumetric method. METHODS: Between January 2012 and October 2020, 67 patients who underwent thoracoscopic segmentectomy of the lower lobe were matched to 67 patients who underwent thoracoscopic lower lobectomy during the same period using propensity score matching analysis...

BACKGROUND: The optimal nadir temperature for hypothermic circulatory arrest during aortic arch surgery remains unclear. We aimed to assess and compare clinical outcomes of all three temperature strategies (deep, moderate, and mild hypothermia) using a network meta-analysis. METHODS: After literature search with MEDLINE and EMBASE through December 2021, studies comparing clinical outcomes with deep (<20°C), moderate (20-28°C), or mild (>28°C) hypothermic circulatory arrest were included...

BACKGROUND: Acute type A aortic dissection (ATAAD) is a life-threatening medical emergency that requires urgent surgical intervention. The mainstay surgical approach to treating ATAAD with aortic arch involvement is total arch replacement (TAR). The frozen elephant trunk (FET) procedure involves TAR with hybrid endovascular stenting of the DTA in a single step using a hybrid prosthesis (HP). The prime example of a FET HP is Thoraflex Hybrid Prosthesis (THP). Another treatment option is the novel Ascyrus Medical Dissection Stent (AMDS) that is deployed as a non-covered stent along with the aortic arch as an adjunct to prior hemi-arch replacement...
