While in many cases they are not directly visualized, awareness of the thoracic nerves and their courses at cross-sectional imaging is important for radiologists. An understanding of the normal function of each nerve is important, as many patients present with neurologic signs and symptoms that can be used to reinforce search patterns for disease and detection of supportive radiologic abnormalities. In the case of primary neoplasms, understanding the expected presence of a nerve in the location of a mass can enhance and improve the accuracy of differential diagnoses...

An 81-year-old man presented with ruptured thoracic aortic aneurysm under stable condition. He had been suffering from chronic obstructive pulmonary disease, chronic renal failure and rheumatoid arthritis. We performed hybrid thoracic endovascular aortic repair via right anterior mini-thoracotomy inserting a device through a conduit on the ascending aorta. The patient was discharged without aorta-related complications.

A 73-year-old male with diabetes mellitius was referred to our hospital for coronary artery bypass grafting (CABG). Preoperative coronary angiography revealed three-vessel coronary disease. Minimally invasive coronary artery grafting (MICS CABG) via left thoracotomy was selected to decrease surgical site infection due to severe diabetes. In situ bilateral internal thoracic arteries (BITA) were harvested using a long type Harmonic scalpel. In situ right internal thorac artery( RITA)-left anterior descending artery (LAD), in situ left internal thorac artery( LITA)-high lateral branch (HL), and aorta-saphenous vein graft (SVG)-#4 posterior descending artery were performed...

Chronic mesenteric ischaemia (CMI) is a rare disorder caused by severe stenosis of the mesenteric arterial supply that results in post prandial pain and weight loss. Treatment options are surgical or endovascular. Surgical bypass can be performed in an antegrade fashion from the supracoeliac abdominal aorta or the distal descending thoracic aorta or in a retrograde fashion from the infra-renal aorta or the common iliac artery. However in some patients with disease of the descending thoracic aorta (DTA) or the abdominal aorta (AA) another site for the proximal anastomosis needs to be found...

BACKGROUND: Although the specialty of cardiothoracic surgery has been practiced in Nigeria for many years, open heart surgery (OHS) has only in the last decade become relatively more frequent, mainly through visiting foreign cardiac surgical teams. At this early phase of development it is faced with multiple challenges, especially financing and local skilled manpower for which solutions have to be identified in order to ensure sustainability and future growth. This study is aimed at highlighting these obstacles to growth of cardiothoracic surgery based on our own institutional experience at Lagos State University Teaching Hospital (LASUTH) and the current status of OHS activity in other cardiothoracic centers in Nigeria...

BACKGROUND: The development of thoracic aortic dissection (TAD) is attributed to a broad range of degenerative, genetic, structural, oxidative, apoptotic, and acquired disease states. In this study, we examined the role of the disturbed p53-MDM2 feed-back loop in the formation of TAD, and one of a potential feed-back loop regulator, TRIM-25. METHODS: Surgical specimens of the aorta from TAD patients (n=10) and controls (n=10) were tested for α-smooth muscle actin (α-SMA),p53,murine double minute2(MDM2) and tripartite motif protein-25(TRIM-25) by western blot, immunohistochemical staining and quantitative real-time reverse transcription polymerase chain reaction (qRT-PCR) , respectively...

The hallmark lesion of tuberculosis in humans and animals is the granuloma. The granuloma represents a distinct host cellular immune response composed of epithelioid macrophages, lymphocytes, and multinucleated giant cells, often surrounding a caseous necrotic core. Within the granuloma, host-pathogen interactions determine disease outcome. Factors within the granulomas such as cytokines and chemokines drive cell recruitment, activity, function and ultimately the success or failure of the host's ability to control infection...

Non-small cell lung cancer (NSCLC) is a lethal cancer-related disease in population. Adenocarcinoma (AC) is subclassified into several subtypes based on the new classification by the International Association for the Study of Lung Cancer, American Thoracic Society and European Respiratory Society in 2011. Correlation between original expression of Crk-like (CRKL) and anaplastic lymphoma receptor tyrosine kinase in diverse histological components of AC and epidermal growth factor receptor (EGFR) or ALK status was evaluated by immunohistochemistry and sequencing in present study...

We report 2 resected cases of superficial type basaloid squamous cell carcinoma of the esophagus. Case 1 is a 67-year-old man who underwent endoscopic submucosalresection for superficialel evated type esophagealcancer of the middle thoracic esophagus. Because the pathological diagnosis of the resected specimen was basaloid squamous cell carcinoma invading to the submucosal layer with lymphatic vessel invasion, esophagectomy was indicated. The resected specimens showed no tumor in the esophagus. However, metastasis was diagnosed in the dissected mediastinall ymph nodes...

BACKGROUND: ST elevation myocardial infarction is a medical emergency and the electrocardiogram is a part of the mainstay in the initial diagnosis. A variety of non-cardiac conditions have been known to mimic the electrocardiographic changes seen in acute coronary syndrome. We present a patient presenting with acute partial intestinal obstruction causing gastric distension and intestinal dilatation who also had dynamic electrocardiographic changes, mimicking anterior ST elevation myocardial infarction...

Maternal and progeny diets supplemented with 2 sources of trace mineral (TM) were evaluated for effects on the size and severity of osteochondrosis (OC) lesions in progeny produced by 64 Landrace × Large White sows. At breeding, sows were randomly assigned to maternal diets (gestation and lactation) consisting 1 of 2 TM treatments. One treatment consisted of inorganic TM (ITM) with ZnO, MnSO, and CuSO at concentrations to provide 150, 50, and 16.5 mg/kg diet of Zn, Mn, and Cu, respectively. The other treatment consisted of the same ITM concentrations plus an additional 50, 20, and 10 mg/kg diet of Zn, Mn, and Cu, respectively, supplied by a blend of AA-complexed TM (CTM) using Availa Sow...

Glucose-induced changes of artery anatomy and function account for diabetic vascular complications, which heavily impact disease morbidity and mortality. Since fibronectin containing extra domain A (EDA + FN) is increased in diabetic vessels and participates to vascular remodeling, we wanted to elucidate whether and how EDA + FN is implicated in diabetes-induced endothelial dysfunction using isometric-tension recording in a murine model of diabetes. In thoracic aortas of EDA(-/-), EDA(+/+) (constitutively lacking and expressing EDA + FN respectively), and of wild-type mice (EDA(wt/wt)), streptozotocin (STZ)-induced diabetes impaired endothelial vasodilation to acetylcholine, irrespective of genotype...

OBJECTIVE: Marfan syndrome (MFS) leads to aortic root aneurysm, while descending thoracic aortic aneurysm (TAA) occurs less commonly. Abdominal aortic aneurysm (AAA) is rarely reported in MFS. Risk factors for AAA are poorly understood and there are no guidelines for AAA screening in MFS. We sought to characterize AAA among Marfan patients in our center. METHODS: The records of 12 adults with MFS and AAA disease were reviewed. Clinical features, imaging, operative reports, and outcomes were analyzed...

Spinal nerve root hemangioblastomas present mostly as intradural-extradurally. Purely extradural spinal nerve root hemangioblastoma is a very rare entity. In this study, we aimed to analyze epidemiological perspectives of purely extradural spinal nerve root hemangioblastomas presented in English medical literature in addition to our own exemplary case. PubMed/MEDLINE was searched using the terms "hemangioblastoma," "extradural," "spinal," and "nerve root." Demographical variables of age, gender, concomitant presence of von Hippel-Lindau (VHL) disease; spinal imaging and/or intraoperative findings for tumor location were surveyed from retrieved articles...

Traumatic injury of the left common carotid is rare but severe disease, and is an uncommon situation in emergency units. Thoracic aortic lesions are often associated with other injuries, making their treatment challenging. We report the case of a successful hybrid approach to treat this lesion using a total supra aortic vessels debranching and a thoracic endovascular graft to cover the rupture, in a 38 years old polytraumatized patient. After aortic, abdominal and orthopaedic surgery, the patient recovered well...
