Filter by: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.
Acute aortic dissection (AAD) involving the ascending aorta (Stanford classification type A) remains a life-threatening disease. Excessive perioperative bleeding requiring massive transfusion of allogeneic blood products, and surgical reexploration remain major challenges in these patients. Previous research has indicated that patients with AAD show pronounced haemostatic alterations prior to surgery which are aggravated during major aortic surgery with cardiopulmonary bypass and hypothermia full heparinization. Intensified anticoagulation management guided by heparin dose response (HDR) calculation, and repeated measurement of heparin concentration may be more effective than standard empiric weight-based heparin and protamine management monitored by activated clotting time (ACT) measurements to suppress thrombin generation during surgery for AAD. This randomized controlled clinical trial compares the impact of two recommended anticoagulation management strategies during surgery for AAD including deep hypothermia on activation of coagulation: Heparin/protamine-management based on HDR-titration by means of HMS Plus® versus current institutional standard (HDR- versus ACT-approach). Primary endpoint is thrombin generation as measured by early postoperative prothrombin fragment 1+2 (F1+2). Secondary endpoints are other markers of coagulation and fibrinolysis as well as clinical outcome.
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.
This study is a pilot study of DLT or BB intubation using a visual laryngoscope in lateral position,To investigate the feasibility of DLT and BB intubation in lateral position,To compare the influence of four endotracheal intubation methods on intrapulmonary shunt,It provides safety guarantee for chest operation under spontaneous breathing anesthesia.
This is a prospective, multicenter and single-arm trail to study the safety and efficacy of the thoracic aortic stent graft system that specially designed for treating aortic dissection.

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 infection rate of thoracic endovascular aortic repair (TEVAR) is unknown due to a lack of epidemiological data. The rate currently available comes from researches conducted decades ago, when open surgery was the standard of care. Because of the potentially fatal consequences of a stent graft infection in the thoracic aorta, the investigators tend to prescribe antibiotic prophylaxis for at least three days. In this study, the investigators are going to collect data on patients receiving TEVAR in the past five years and provide the following information: a. the infection rate (MAGIC classification), b. the rate of fever, c. the results of the lab tests, such as the WBC count and C-reaction protein. d. risk factors associated with infection and fever.
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.
