Acute DeBakey type I aortic dissection (ATAD) is one of the most lethal surgical emergencies. The conventional operative strategy is hemiarch replacement under cardiopulmonary bypass support to replace the diseased segment of the ascending aorta. However, in patients with dissection involving the whole aortic arch and descending thoracic aorta, the presence of the persistently perfused false lumen can lead to late aneurysm formation and require a second-stage operation, and this reduces long-term survival. In the surgical literature, there is growing evidence that the presence of Distal Anastomosis New Entry (DANE), which is a new intimal defect related to the trauma created by surgical sutures, is associated with persistent perfusion of the false lumen, aortic size growth, and the need of re-operation. The Ascyrus Medical Dissection Stent (AMDS; Artivion, Atlanta, Georgia, USA) is a hybrid prosthesis with a proximal sewing collar and distal nitinol self-expanding un-covered stent system designed to reduce the occurrence of DANE and hopefully depressurize the false lumen and lead to remodeling of the aortic wall. The investigators plan to prospectively recruit consecutive patients with acute ascending thoracic aortic dissection patients (Excluding DeBakey II) and randomized them, after informed consent, into either the conventional hemiarch replacement group (Hemiarch-C) or the hemiarch replacement plus AMDS implantation group (Hemiarch-AMDS). The participating team will collect pre-operative, intra-operative and post-operative clinical and radiological parameters for two groups of patients. Written informed consent, specifically allowing the use of clinical records for this randomized study, will be obtained from every patient prior to data collection. Complete DICOM image files of the CT scans will be evaluated by two independent fully qualified Radiologists. Our primary outcome is the radiological detection of DANE in Hemiarch-C and Hemiarch-AMDS groups within the 12-month follow-up period. This study will be the world's first randomized control trial in ATAD to compare the prevalence of DANE in Hemiarch-C and Hemiarch-AMDS. It could be a guideline-changing study for the treatment of ATAD and its impact on the immediate survival, second-stage treatment, and long-term survival of patients suffering from ATAD.
The etiology and specific pathogenesis of many cardiovascular diseases such as coronary atherosclerosis, cardiomyopathy, atrial fibrillation, and stroke are still unclear. Improving diagnosis and treatment, clarifying the pathogenesis, and providing scientific basis for the prevention and treatment are hot research topics in the study of cardiovascular and cerebrovascular diseases. This study intends to collect clinical data and biological specimen data of patients with cardiovascular and cerebrovascular diseases who meet the inclusion and exclusion criteria, and use multi-omics technology to deeply understand the pathogenic mechanisms of cardiovascular and cerebrovascular diseases and provide new ideas for specific and individualized treatment of patients with cardiovascular and cerebrovascular diseases, to construct early predictive prognostic models and provide a basis for effective treatment of clinical practice in patients with cardiovascular and cerebrovascular diseases.
This study will construct a retrospective-prospective long-term follow-up cohort and management system for aortic dissection through a multicentre collaborative network. This study aims to investigate the disease characteristics, progression patterns, clinical features, natural course and factors affecting the disease course and prognosis of patients with aortic dissection by retrospectively collecting data and prospectively enrolling patients.
There are no endoluminal stent systems available on the Chinese market for the effective treatment of aortic arch lesions (involving aortic arch aneurysms, aortic coarctation, aortic pseudoaneurysms, aortic ulcers, and intermural hematomas), and therefore this study is intended to be a prospective, single-arm study.
The goal of this RCT is to compare outcome with McGrath vs Macintosh laryngoscopes among patients undergoing thoracic surgery. The main questions it aims to answer are, 1. Rate of successful intubation at first attempt and 2. Time for intubation required with each device. Participants are required to sign the informed consent for, they will be placed in two groups, Group A: Macintosh (DL) Group B: McGrath (VL) Researchers will compare in Group A: Macintosh (DL) and Group B: McGrath (VL) the differences in rate of successful intubation at first attempt and time for intubation required with each device.
The goal of this clinical trial is to see if the investigators can find a safer and quicker way to localize the correct spinal level before the start of thoracic spinal surgery. Currently, this localization is done with the help of spinal needles and fluoroscopy. There are some inherent issues with accuracy due to individual factors such as the type of operating table or the body habitus. The investigators want to know if the use of ultrasound to count ribs and mark the corresponding spinal level would be a quicker and possibly even more accurate than the use of fluoroscopy. Participants who will be approached for this study are those that have already consented to undergo thoracic spinal surgery. Once they have been consented for the study, they will undergo anesthesia as per normal and positioned prone for the intended surgery. At this juncture, the radiographers will be setting up to perform fluoroscopy to confirm the spinal level and for the surgeons to mark the skin. For the purposes of the study, the investigators will use the ultrasound to count the ribs and mark the corresponding spinal level. Participants will undergo fluoroscopy to mark the skin level as well. The investigators are studying to see if the ultrasound method is just as accurate as the traditional fluoroscopy method. The results will be binary and will be recorded. The study ends at this point and no further participation is required from the patient.
A multicenter, retrospective study to evaluate the real-world efficacy of the Fabulous thoracic aortic stent system in the treatment of Stanford Type B aortic dissection.
The goal of this randomized clinical trial is to compare a liberal versus restrictive oxygen supply (fraction of inspired oxygen, FiO2) strategy in patients scheduled for thoracic surgery requiring one-lung ventilation during lung isolation. The primary and secondary outcome parameters are: - oxygenation of the blood after 30 minutes of one-lung ventilation, assessed by PaO2/FiO2 ratio - time to lung collapse after start of one-lung ventilation Participants in the control goup will receive an oxygen content of 100% before lung isolation, which will be subsequently decreased to achieve normoxia or mild hyperoxia (PaO2 of 75-120 mmHg). The intervention group will receive the previous, during two-lung ventilation set, oxygen content and after lung isolation oxygen supply will be increased to secure adequate oxygenation of the blood (PaO2 75-120 mmHg) during one-lung ventilation. The investigators hypothesize, that a higher fraction of inspired oxygen may impede hypoxic pulmonary vasoconstriction of the collapsed lung and thus decrease overall oxygenation performance during one-lung ventilation. Secondary endpoint will be the time to lung collapse, as a lower fraction of inspired oxygen and thus a higher nitrogen content may impede lung collapse.
Type A aortic dissection (TAAD) is a potentially life-threatening pathology associated with significant risk of mortality and morbidity. In acute forms of type A aortic dissection (TAAD) mortality is 50% by 24 h and 50% of patients die before reaching a specialist center. Rapid diagnosis and subsequent prompt surgical repair remain the primary goal for these patients. In the last decade it has been observed that improvements in diagnostic techniques, initial management and increased clinical awareness have contributed to a substantial increase in the number of patients benefiting from a prompt diagnosis and undergoing surgery.However, survival after surgical repair has not yet reached optimal follow-ups and is burdened by high in-hospital mortality(16-18%)
