This retrograde flow presupposes that the vertebral artery is of usual origin from the superior surface of its ipsilateral subclavian artery. We present a rare variant of the right vertebral artery originating as part of a trifurcated brachiocephalic trunk in a 76-year-old female cadaver. Our discussion is focused on the clinical implication of this variant should there be a proximal occlusion to the right subclavian artery or such occlusion occurring in the proximal origin of the brachiocephalic trunk off the aortic arch. Even though aberrant vertebral arteries are often asymptomatic, but a good search should be made to locate their aberrant origins. Good knowledge of the anatomic location of the vertebral artery is important to endovascular, and maxillofacial and neurosurgeons engaged in surgical interventions in the head and neck region to assist in the selection of appropriate surgical interventions and to neuroradiologists, in the interpretation of images. The main thrust of our report is focused on a modeled occlusion in the proximal region of the subclavian artery or in the proximal segment of the brachiocephalic trunk and the clinical outcome of retrograde flow in the variant right vertebral artery originating from a bifurcated brachiocephalic trunk in both circumstances. When a retrograde flow is modeled in a hypothetical proximal occlusion to the subclavian artery only, this does not give any vascularization to the subclavian artery since the occlusion is occurring distally to the retrograde flow. However, in the case of occlusion occurring, the proximal origin of the brachiocephalic trunk before trifurcating, and before the trifurcation, a reversed flow from the variant vertebral artery will send blood to vascularize both the right common carotid and the right subclavian arteries, resulting in a hypothesized combined Common Carotid-Subclavian Steal Syndrome (CC-SSS). This emphasizes clinically that varying origins of the vertebral artery would play dissimilar roles in occlusion or stenosis in the proximal segments of the major supra-aortic vessels.","PeriodicalId":79324,"journal":{"name":"Cardiovascular surgery (London, England)","volume":"2 1","pages":"18-21"},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70039425","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Leaflet augmentation of the tricuspid valve is less well described. The aim of this retrospective study was to assess short- and long-term valve function and patient outcome in all patients receiving tricuspid valve leaflet augmentation with either Cormatrix or bovine/autologous pericardium in our institution from 2007 to 2016. Materials and methods: NYHA class, diagnosis, type of surgery and health state were found through chart review. Echocardiography exams before surgery, 1 month after, 6 months after, and latest exam were analyzed regarding biventricular function, valve function, leaflet mobility and –thickness. Results: In eight patients; Cormatrix (n=4), bovine pericardium (n=3), and autologous pericardium (n=1) were used for 7 anterior leaflet extensions and 1 septal leaflet extension. Follow-up ranged from 6 to 132 months. Three patients had died, two in the Cormatrix group, and one in the pericardial group. Over time, coaptation length (12 ± 5 mm vs. 8 ± 3 mm, p=0.03) decreased significantly in the Cormatrix group, while none of the other parameters differed significantly. A tendency towards reduced leaflet mobility and thickening of the pericardialextended leaflets were seen over time. Conclusion: Cormatrix and pericardium as patch material for tricuspid leaflet extension are comparable regarding valve performance and durability of the repair in this study, though resorption of Cormatrix material seems to take place leading to decreasing coaptation height. This is a sign of tissue remodelling. Leaflet mobility was reduced in the pericardial repair group and may likely be related to thickening of pericardial patch material that occurred over time.","PeriodicalId":79324,"journal":{"name":"Cardiovascular surgery (London, England)","volume":"1 1","pages":"1-7"},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70038611","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The purpose of the study was to analyze the utility of assessing flow in the thoracic descending aorta using magnetic resonance imaging (MRI) in patients with AC. Methods: Patients with a diagnosis or suspicion of AC, who underwent MRI study between 2008-2016 in a single tertiary center, were retrospectively studied. MRI standardized protocol included gadolinium enhanced angiographic 3-D sequences to evaluate relative stenosis (RS) and phase contrast imaging to assess flow in the descending aorta. Results: 106 patients {70 men (66%), mean age 22 ± 17 years} were included. Of these, 28 (26%) required surgical intervention during the first year after evaluation and 9 (9.3%) required percutaneous treatment. AUROC curves were applied to find best cut-off points of imaging variables. Imaging variables were entered into a multivariate logistic regression model including the presence of arterial hypertension. Percentage of flow increase was shown to be an independent predictor of the need for an intervention (OR, 7.2; 95%CI, 1-20; p=0.03) and adding this parameter in the standard work-up represented a significant increase in diagnostic accuracy (S, 85%; Sp, 89%; vs. S, 62%; Sp, 92%).

Methods: This is a retrospective study of data from 418 adult patients undergoing cardiac surgery with cardiopulmonary bypass between 1st January 2015 and 31 December 2016 in the department of cardiovascular and thoracic surgery of the Sahloul University Hospital of Sousse. The EuroSCORE ΙΙ is calculated using the application validated on the site www.euroscore.org. The performance of the score is evaluated by analyzing its discriminative power by constructing the ROC curve and analyzing its calibration using the Hosmer-Lemeshow statistics. Results: The EuroSCORE II shows good discriminative power in our population with an area under the ROC curve >0.7 in all study groups (0.864 ± 0.032 for general cardiac surgery, 0.822 ± 0.061 for coronary surgery, 0.864 ± 0.052 for valvular surgery, and 0.900 ± 0.041 for urgent cardiac surgery).

The robotic approach allowing more intuitive movement, greater flexibility, and high definition 3D vision appears to encourage surgeons to adapt the technique. Methods: This review examines the recent English lit of the early surgical experience of the da Vinci robotic system in the treatment of lung cancer, esophageal resection and mediastinal pathology. Conclusion: The application of robotic technology to thoracic surgery has proven to be at least comparable to open or video assisted thoracoscopic techniques in several areas and in some, possibly superior. If the widespread application of robotic technology allows greater access to minimally invasive thoracic surgery, with equivalent or superior oncological and perioperative outcomes, then it seems logical that robotic technique will become the standard for many general thoracic surgical procedures.","PeriodicalId":79324,"journal":{"name":"Cardiovascular surgery (London, England)","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70039611","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Children swallow objects due to their curiosity and are prone to aspiration. However in adults there are different risk factors for aspiration; such as alcohol consumption, addiction, drug consumption, senility, seizure, trauma, mental retardation, and artificial dentures [1]. In some cases, it may happen accidentally, and risk factors are not involved. In this particular case, air gun bullet has been swallowed (Figure 1). The shooter had put a bullet in his mouth in order to reload his gun and shoot rapidly; then swallowing and aspiration happened. In this case, because the foreign body is opaque, chest X-ray can be helpful for diagnosis (Figure 2). The alternative way to diagnose is fiberoptic bronchoscopy; which is sometimes considered a therapeutic strategy (Figure 3). Foreign body aspiration in tracheobronchial tree requires immediate diagnosis and removal; because the ignored objects may result in complications like infection, abscess, empyema, and haemoptysis or even bronchopleural fistula [2]. Therapeutic options to remove aspirated foreign bodies from the respiratory tract are carried out through fiberoptic and rigid bronchoscope [3]. In cases of immediate removal of the foreign body, the outcome will be excellent; and there will be no specific complication and sequel. In some rare cases, surgery is needed to remove the foreign body; however, surgery is mostly required in situations with late diagnosis and occurrence of complications.","PeriodicalId":79324,"journal":{"name":"Cardiovascular surgery (London, England)","volume":"1 1","pages":"8-10"},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70039132","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
