Filter by:Acute aortic syndrome (AAS) is a life-threatening emergency condition affecting the upper aorta affecting ~4000 people in the (United Kingdom; UK) a year with an ED misdiagnosis rate as high as 38%. Previous research has identified several strategies combining clinical probability scoring with blood tests (D-Dimer) to rule out the condition but when applied to a large population (ED) with relatively low numbers of actual cases, these result in a high rate of computed tomographic angiography (CTA) scanning. Current guidelines reflect the uncertainty of existing evidence. This study, the first phase of three, aims to describe the characteristics of ED attendances with possible AAS, to determine the service implications of using different diagnostic strategies and inform future research. The investigators plan to recruit all ED attendances with possible AAS over a 1-4 week period. The investigators plan a prospective and retrospective approach to data collection adopting a waived-consent strategy with endpoint measures describing the characteristics of patients presenting with possible AAS.
Objective Complex aortic pathology has been revolutionized with the use of hybrid prostheses such as the Thoraflex® Hybrid Frozen Elephant Trunk (FET). The aim of this study was to evaluate the midterm results of secondary extension of the FET by thoracic endovascular aortic repair (TEVAR). Few data are present in the literature regarding the outcomes of this secondary treatment. The investigators perform a prospective study between 2015 and 2022 in a tertiary aortic center on all consecutive patients having undergone TEVAR after FET implantation. The TEVAR endograft covered most of the 10 cm FET module with 2 to 4 mm oversizing. All patients were monitored by computerized angiography (CTA) at 6-month and yearly thereafter. The aim of this study was the feasibility of theses secondary connexion and the mid term outcomes of the endovascular treatment.
The investigator would like to conduct a study in patients undergoing thoracic surgery to evaluate the effectiveness of thoracic ultrasound in the decision to discharge the patient after pleural drain removal.
Aortic dissection in pregnancy represents a lethal risk to both the mother and fetus, it has yet to yield the optimal therapeutic strategy. The aim of this study was to characterize the clinical features and outcomes in women with pregnancy-related acute aortic dissection, and to suggest therapeutic guidelines.
A single-center prospective study. Patients undergoing surgery for acute type A aortic dissection with femoral arterial cannulation between 2017 and 2022 at the Karolinska University Hospital in Stockholm, Sweden are eligible. Femoral cannulation was performed either with surgical cut-down and arterial puncture under direct vision or percutaneously with planned percutaneous arteriotomy closed using a plug-based arteriotomy closure device (MANTA, Essential Medical Inc., Malvern, Pennsylvania). Data regarding preoperative clinical characteristics and operative details were obtained by medical records review.

Type A acute aortic dissection (TA-AAD) patients are prone to life-threatening complications and death during the acute phase. Currently, little evidence is available with regards to the relationship between eosinophils (EOS) and TA-AAD. A total of 274 patients with TA-AAD were eligible for inclusion and 54 patients deceased within 1 month following surgery. Multivariate regression analysis, the general linear model repeated-measures ANOVA analysis (corrected by Greenhouse-Geisser test), receiver-operating characteristics (ROC) curves and a Kaplan-Meier curve were applied for statistical analysis.
This study constructed a retrospective cohort study by retrospectively analyzing the data of all patients with aortic dissection from January 1, 2012 to December 31, 2021 from the Cardiovascular Disease Registration System of Jiangsu Province in China and the data of similar diseases in recent years from National Inpatient Sample database in the United States
The aim of this study is to compare the effects of thoracic extension versus thoracic stabilization exercises on pain, stiffness, range of motion, disability and posture in patients with Maigne's thoracic pain.This study will be a randomized clinical trial and 32 patients fulfilling the inclusion criteria will be included in the study. they will be allocated into 2 groups using non- probability purposive sampling technique. Group A will receive conventional treatment, myofascial release, thoracic spine mobilization with Thoracic Extension exercise program, while Group B will receive conventional treatment, myofascial release, thoracic spine mobilization with Thoracic Stabilization exercise program. Outcome measure: Numeric Pain Rating Scale, Goniometer, Thoracic Stiffness Index, Revised Oswestry Thoracic Pain Disability Questionnaire, standing thoracic X-ray and Flexi curve ruler, will measure pain, thoracic flexion and extension, Cobb's angle, kyphosis index, thoracic stiffness index and disability. Both groups will receive a total of 45 minutes session, thrice a week for 3 weeks. Measurements will be taken at the baseline, at the end of 3rd week and for long-term effects at the end of 6th week. Data will be analyzed by SPSS version 21.
The investigators focus on the patients who underwent aortic root surgery for acute type A aortic dissection between 2005.01-2021.11. The patients are divided into 3 groups according to the different aortic root surgical methods(Bentall，David and root reconstruction). Clinical data including age, gender, comorbidities, surgical informations and perioperative informations will be collected. All patients will receive follow-ups in hospital or by telephone. All the informations will be analyzed by SPSS to show the difference of both perioperative and long-term results among different surgical strategies.
