BACKGROUND: A variety of surgical techniques exist to manage long-gap esophageal atresia (LGEA), including gastric pull-up (GPU), colonic interposition (CI), jejunal interposition (JI), and distraction lengthening. Salvage reconstruction for late failure of any conduit type is a complex surgical problem fraught with technical difficulty and significant risk. Jejunal interposition can be used as a salvage procedure in the management of LGEA. However, the opposing requirements of conduit length and adequate perfusion make the procedure technically challenging...

OBJECTIVES: Saphenous vein graft (SVG) remains the predominant conduit used in coronary surgery. The internal mammary artery has higher later term patency and confers superior survival. Current debate focuses on the increased use of arterial conduits rather than eradication of venous conduits. METHODS: Patient data extracted from the Australian and New Zealand Society of Cardiothoracic Surgeons database from 2001-2013 were linked to the national death registry held by the Australian Institute of Health and Welfare for all-cause mortality with censor date 7 October 2014...

This case will illustrate the clinical and unique technical challenges, not previously reported, in a patient with a history of progressive left ventricular (LV) systolic dysfunction, congestive heart failure (CHF), myocardial infarction (MI), and a complex bifurcation lesion of the left subclavian artery (SA) involving the left internal mammary artery (LIMA) in the setting of coronary subclavian steal syndrome (CSSS). The approach to this lesion is complicated by significant LIMA involvement requiring intervention directed toward both the SA and the LIMA in the presence of severe LV systolic dysfunction...

OBJECTIVE: The main objective of this study was to define a role of sphingosine-1-phosphate receptor 1 (S1PR1) in the arterial injury response of a human artery. The hypotheses were tested that injury induces an expansion of S1PR1-positive cells and that these cells accumulate toward the lumen because they follow the sphingosine-1-phosphate gradient from arterial wall tissue (low) to plasma (high). METHODS: A humanized rat model was used in which denuded human internal mammary artery (IMA) was implanted into the position of the abdominal aorta of immunosuppressed Rowett nude rats...

Locally advanced breast cancer patients with expander or implant reconstructions who require comprehensive postmastectomy radiotherapy (PMRT) can pose unique treatment planning challenges. Traditional 3D conformal radiation techniques often result in large dose inhomogeneity throughout the treatment volumes, inadequate target coverage, or excessive normal tissue doses. We have developed a volumetric modulated arc therapy (VMAT) planning technique without entering through the ipsilateral arm that produced adequate target volume coverage, excellent homogeneity throughout the target volume, and acceptable doses to the normal structures...

Sequential grafting may be an effective way to maximize the benefits of the left internal mammary artery (LIMA) conduit. Despite increasing clinical application, the strategy of sequential LIMA grafting has not been proven its superiority. This single-center retrospective study aimed to evaluate the in-hospital and mid-term outcomes of sequential grafting of in situ skeletonized LIMA to the left coronary system.According to the use of sequential or separate LIMA grafting, 1505 eligible patients were assigned to a sequential group (n = 230) and a control group (n = 1275)...

MicroRNA (miR) is reported to be involved in vascular inflammation and may represent a novel class of diagnostic biomarkers in cardiovascular disease. We aimed to identify the miR expression profile in human advanced coronary atherosclerotic plaques (CAP) and to connect this expression to the processes in atherosclerosis. Microarray techniques and TaqMan polymerase chain reaction were used to analyse the global expression of 352 miRs in CAP obtained during ACS MULTI-LINK study. 11 miRs were selected on the basis of their implication in atherosclerosis, endothelial activation, and inflammation...

BACKGROUND: Bilateral internal mammary artery (BIMA) grafting in diabetic patients undergoing coronary artery bypass grafting (CABG) remains controversial. Our study compared morbidity and mortality between 1)diabetic and non-diabetic BIMA patients and 2)diabetic BIMA versus diabetic patients who underwent left internal mammary artery (LIMA) grafting only. METHODS: Patients who underwent isolated CABG from July 2011 - June 2016 at any of the 10 centers in Maryland were propensity scored across 16 variables...

The treatment of primary lung cancer of the left upper lobe in those with prior coronary artery bypass graft is difficult to plan and execute due to potential for invasion into coronary grafts, particularly the left internal mammary. We present a patient with squamous cell carcinoma invading into coronary artery bypass grafts, but successfully treated by combination of percutaneous coronary intervention followed by video-assisted thoracoscopic surgery.

BACKGROUND: Atherosclerosis is a disease of the arterial wall with predilection to some sites on others. MicroRNAs (miRNAs) are a class of the non-coding RNAs regulating the target gene expression at post-transcriptional level. Different miRNAs were found at distinct stages of plaque development and expression of miRNAs' might play an important role in the local behaviour of atherosclerotic plaques. OBJECTIVE: We aimed to investigate and compare mirR-221/222 expression levels in tissues and in circulation in patients with and without overt atherosclerosis...

Hybrid coronary revascularization (HCR) combines surgical bypass with percutaneous coronary intervention (PCI) performed either during the same procedure or in a staged approach within 60 days. Coronary artery bypass grafting using the left internal mammary artery (LIMA) has shown excellent long-term patency with improved patient survival. It remains the gold standard treatment for the majority of patients with multivessel coronary artery disease. However, saphenous vein grafts have poor long-term patency. Advances in stent technology have resulted in reduced rates of thrombosis and restenosis, making PCI a viable alternative to coronary surgery in selected patients...

A 42-year-old woman with a large congenital giant arteriovenous malformation in the left supraclavicular fossa underwent surgical resection. Although endovascular treatment was initially planned, it was impossible to occlude the multiple feeding arteries (transverse cervical, clavicular branch of left internal mammary, thoracoacromial, anterior/posterior circumflex humeral), and the anatomy was difficult. After removal of the left clavicle, the arteriovenous malformation was exposed. Care was taken to not injure the brachial plexus, and each feeding artery was ligated, followed by division of the drainage veins...

PURPOSE: Pharmacokinetic (PK) data are generally derived from blood samples withdrawn serially over a defined period after dosing. In small animals, blood sampling after dosing presents technical difficulties, particularly when short time intervals and frequent sampling are required. Positron emission tomography (PET) is a non-invasive functional imaging technique that can provide semi-quantitative temporal data for defined volume regions of interest (vROI), to support kinetic analyses in blood and other tissues...

INTRODUCTION: Coronary artery bypass graft (CABG) patency is an important variable, but rarely studied as the main outcome. The best use of bilateral internal mammary artery (BIMA) grafting regarding configuration type or combination with saphenous vein graft (SVG) is still debated. PURPOSE: To find independent predictors for need of cardiac catheterization and for significant lesions in CABG follow-up. METHODS: Retrospective cohort including all patients who underwent isolated CABG with BIMA grafts between 2004 and 2013 in a tertiary center...

BACKGROUND: Recent evidence suggests that resuscitative endovascular balloon occlusion of the aorta (REBOA) is an effective life-saving intervention in patients with severe torso trauma. However, the deployment of REBOA in patients with isolated penetrating intrathoracic injuries remains controversial. We propose that a median sternotomy be performed in conjunction with REBOA as a feasible and effective means of hemorrhage control in patients suffering from penetrating chest trauma who present hemodynamically unstable...

Spontaneous hemothorax is an uncommon event that can occur in patients with a history of neurofibromatosis type 1 because of intrathoracic vascular malformations that predispose to aneurysms or bleeding from thoracic tumors. Only 53 cases of this rare association have been reported in the literature since 1975. We described 2 cases: one patient was a 73-year-old man with a right hemothorax secondary to an intercostal neurofibroma; the other was a 35-year-old woman with a left hemothorax secondary to a neurofibroma that compromised the internal mammary artery...
