Long-Term Results After Repair of Type A Acute Aortic Dissection According to False Lumen Patency
2009
Background Late survival and freedom from retreatment on the descending aorta was evaluated after ascending aortic repair for type A acute aortic dissection (TAAAD). Methods Between March 1992 and January 2006, 189 TAAAD patients (mean age, 52 ± 11; range, 17 to 83 years) were included; of these, 58 had a patent false lumen, and 49 had Marfan syndrome. The descending aorta was evaluated postoperatively with computed tomography (CT). Late outcomes were assessed by Cox regression analysis and actuarial survival and freedom from retreatment by the Kaplan-Meier method. Mean follow-up was 88 ± 44 months. Results There were 38 (20%) late deaths. At 10 years, survival was 89.8% ± 2.1% for patients…
Radical pleurectomy and chemoradiation for malignant pleural mesothelioma: The outcome of incomplete resections
2013
The type of surgery (radical pleurectomy (RP) vs. extrapleural pneumonectomy (EPP)) remains controversial for malignant pleural mesothelioma (MPM). Macroscopic complete resection (MCR) is a key prognostic factor. It is unclear, if patients undergoing incomplete RP within a standardized multimodality treatment protocols have any advantage in terms of survival and if EPP could theoretically have avoided incomplete resections (R2).Eighty-eight patients underwent RP followed by chemoradiation from 2002 to 2011 within a prospective multimodality treatment study at a single institution. MCR were compared to R2 within this patient cohort retrospectively. EPP eligibility was assessed retrospectivel…
Thoracic shaping technique to avoid residual space after extended pleurectomy/decortication
2013
Extended pleurectomy/decortication or radical pleurectomy is defined as a lung-sparing surgical procedure for malignant pleural mesothelioma. A significant size mismatch between the thoracic cavity and the reduced size of the remaining lung might occur as a result of multiple resections at different sites and lead to residual thoracic space. Residual thoracic space and significant air leakage might result in postoperative complications. A simple technique of diaphragm reconstruction to avoid the residual thoracic space and to reduce the incidence of postoperative complications is described.
Acute onset of esophageal duplication cyst in adult. Case report.
2009
Esophageal duplication (ED) cyst is unusual congenital disorder of the foregut, accounting for 10% to 15% of duplications of all foregut cysts. We report a case of esophageal duplication with acute clinical presentation, treated successfully with surgical resection.46-year-old man with acute dysphagia and gastroesophageal reflux of 2 weeks duration, showed submucosal bulging mass in the posterior wall of the middle third of oesophagus, fluid-filled cystic structure, dyshomogeneous, low-attenuation mass with smooth borders compatible with an hemorrhagic esophageal duplication cyst. With the suspect of acute presentation of a complicated esophageal cyst, the patient underwent surgery by right…
Noninvasive assessment of respiratory muscle strength and activity in Myotonic dystrophy
2017
Objective To evaluate sensitivity/specificity of the maximum relaxation rate (MRR) of inspiratory muscles, amplitude of electromyographic activity of the sternocleidomastoid (SCM), scalene (SCA), parasternal (2ndIS) and rectus abdominis (RA) muscles; lung function and respiratory muscle strength in subjects with Myotonic dystrophy type 1 (DM1) compared with healthy subjects. Design and methods Quasi-experimental observational study with control group. MRR of inspiratory muscles, lung function and amplitude of the electromyographic activity of SCM, SCA, 2ndIS and RA muscles during maximum inspiratory pressure (PImax), maximum expiratory pressure (PEmax) and sniff nasal inspiratory pressure (…
Uniportal Video-Assisted Thoracoscopic Surgery Resection of a Giant Midesophageal Diverticulum
2017
We describe a new video-assisted technique for the management of a giant midesophageal diverticulum using a single 5-cm port. It maintained the same principles of the traditional open technique as diverticulectomy, myotomy, and fundoplication. The better visualization of the main esophageal body, diverticulum, and esophagogastric junction and the better alignment of the stapler cartridge to the longitudinal axis of the esophagus are all technical factors supporting our procedure. Heavily calcified mediastinal lymph nodes and diffuse pleural adhesions are the main contraindications. However, future experiences are needed before this technique can be recommended as acceptable treatment. (C) 2…
Redox Regulation of Dihydrofolate Reductase: Friend or Troublemaker?
2015
Oxidative stress is a hallmark of cardiovascular diseases1 and a major contributor to vascular dysfunction.2 On the basis on recent concepts, vascular oxidative stress is caused mainly by infiltrating inflammatory cells such as monocytes/macrophages or leucocytes,3,4 producing so-called kindling radicals that lead to the activation of secondary, vascular enzymatic sources of reactive oxygen species (mainly superoxide).2,5 A prominent example is the uncoupled nitric oxide (NO) synthase, which means that an NO-producing antiatherosclerotic enzyme is getting switched to a superoxide-producing proatherosclerotic enzyme.2 Molecular mechanisms causing endothelial NO synthase (eNOS) uncoupling or …
Mediastinal syndrome from plasmablastic lymphoma in human immunodeficiency virus and human herpes virus 8 negative patient with polycythemia vera: a …
2017
Background: Plasmoblastic lymphoma is a rare and aggressive subtype of diffuse large B cell lymphoma, which occurs usually in the jaw of immunocompromised subjects. Case presentation: We describe the occurrence of plasmoblastic lymphoma in the mediastinum and chest wall skin of an human immunodeficiency virus-negative 63-year-old Caucasian man who had had polycytemia vera 7 years before. At admission, the patient showed a superior vena cava syndrome, with persistent dyspnoea, cough, and distension of the jugular veins. Imaging findings showed a 9.7 × 8 × 5.7 cm mediastinal mass. A chest wall neoformation biopsy and ultrasound-guided fine-needle aspiration biopsy of the mediastinal mass allo…
Role of TGF-β Pathway Polymorphisms in Sporadic Thoracic Aortic Aneurysm: rs900 TGF-β2 Is a Marker of Differential Gender Susceptibility
2013
Thoracic aortic aneurysm (TAA) is a progressive disorder involving gradual dilation of ascending and/or descending thoracic aorta with dissection or rupture as complications. It occurs as sporadic or defined syndromes/familial forms.Genetic, molecular and cellular mechanims of sporadic TAA forms are poorly characterized and known. Thus, our interest has been focused on investigating the role of genetic variants of transforming growth factor-β(TGF-β) pathways in TAA risk. On the other hand, no data on the role of genetic variants of TGF-βpathway in sporadic TAA exist until now. In addition, other cytokines, including IL-10, orchestrate TAA pathophysiology. Their balance determines the ultima…
Identification of Three Particular Morphological Phenotypes in Sporadic Thoracic Aortic Aneurysm: Phenotype III As Sporadic Thoracic Aortic Aneurysm …
2014
Abstract Aging has a striking impact on the heart and the vascular system, particularly on the large elastic arteries (i.e., aorta), resulting in a multitude of changes at different structural and functional levels. As result, medial degeneration (MD) occurs. A characteristic example of MD is sporadic thoracic aortic aneurysm (S-TAA), whose patho-physiological mechanisms remain unclear. In this study, typical MD morphological phenotypes were researched in S-TAA cases and control aorta specimens by histopathological and immunohistochemical analyses. Three phenotypes (I, II, and III) were detected, but mainly the phenotype III was observed. Elevated cystic MD, plurifocal medial apoptosis, and…
