Filter by:Acute kidney injury (AKI) is a common and serious complication after aortic dissection (AD), and it is closely related to the inflammatory response associated with cardiopulmonary bypass. Hemoperfusion can reduce the level of systemic inflammatory response effectively in patients with sepsis. Some studies have tried to apply hemoperfusion to cardiopulmonary bypass surgery, and put forward the concept of "absorptive cardiopulmonary bypass", but there are few related research reports. The use of hemoperfusion during cardiopulmonary bypass can reduce the level of systemic inflammatory response, thereby reducing the risk of postoperative AKI and improving the prognosis of patients. The Cardiovascular Surgery Department of the First Affiliated Hospital of Jiaotong University is one of the first demonstration units of "adsorption-type cardiopulmonary bypass" in China. Our previous retrospective analysis shown that intraoperative hemoperfusion can effectively reduce the occurrence of postoperative AKI in patients with AD, compared with traditional cardiopulmonary bypass. In addition, previous studies have found that the increased expression of CIRP after cardiopulmonary bypass can aggravate the oxidative stress and mitochondrial dynamics disorder in renal tubular epithelial cells, thereby inducing AKI. This project is a single-center randomized controlled study. It intends to investigate whether the application of hemoperfusion during cardiopulmonary bypass in patients with AD to reduce the level of systemic inflammatory response can reduce the incidence of postoperative AKI and improve the patient's discharge outcome. At the same time, exploratory studies were conducted to investigate whether hemoperfusion could effectively reduce the expression level of CIRP in the circulation. The successful implementation of this study can provide effective intervention methods and related theoretical basis for reducing the risk of AKI after aortic dissection.
This study is designed to evaluate the effects of glucocorticoid(GC) on improving post-operative organ dysfunction in patients with acute type A aortic dissection(aTAAD). Subjects with confirmed diagnosis of aTAAD undergoing surgical treatment will be enrolled and 1:1 randomly assigned to receive either glucocorticoids or normal treatment. All patients in the glucocorticoids group will be given methylprednisolone intravenously for 3 days after enrollment. The primary endpoint will be the amplitude of variation of Sequential Organ Failure Assessment score on post-operative day 4 compared to baseline.
The purpose of the LCCC 2202 is to evaluate the barriers and facilitators to implementing perioperative "ePRO monitoring". This study will inform a future hybrid effectiveness study (LCCC 2141:Improving Thoracic Surgical Care Using Electronic Patient-Reported Outcomes (ePROS). Eligible thoracic surgery patients will be enrolled to ePRO monitoring using web-based or telephone surveys. Patients will be asked to self-report symptoms for remote monitoring by their care team. Patients will be approached for a semi-structured interview to understand the barriers and facilitators to ePRO use.
Video-assisted thoracic surgery (VATS) has become a common procedure in thoracic surgery. Severe postoperative pain may be encountered in patients undergoing VATS. Analgesic methods such as thoracic paravertebral block (TPVB), intercostal block, serratus anterior plane block (SAPB), and erector spinae plane block (ESPB) are widely used for VATS. Among these methods, ultrasound (US) guided TPVB is the most preferred method. In recent years, the frequency of application of plane blocks as a component of multimodal analgesia has been increased. ESPB and SAPB are some of them. There are two techniques for SAPB application. In Deep SAPB (DSAPB) application, a local anesthetic agent is given under the serratus anterior muscle. In the Superficial SAPB (SSAPB) application, the local anesthetic agent is given above the serratus anterior muscle. Since it is done by entering from the same point in two applications, it is possible to perform these two applications at the same time with a single needle entry. The mechanisms of regional analgesia techniques used after thoracic surgery operations are also different from each other. Therefore, it may be possible to obtain a more effective analgesic effect in patients by combining the mechanism of action of DSAPB and SSAPB, as in the multimodal analgesia method. This study seeks to evaluate the effect of TPVB and combined SAPB (CSAPB) after VATS.
The direct oral anticoagulants (DOACs) and particularly the FXa inhibitors are a concern in patients presenting with type A aortic dissection as this may contribute to severe bleeding complications. The antidote andexanet alfa (Ondexxya®) can interact with the heparin- anti-thrombin III (ATIII) complex which may neutralize the anticoagulant effect of heparin and the use of andexanet alfa before surgery necessitating heparin-anticoagulation has been reported to cause unresponsiveness to heparin. The investigators have preliminary in-vitro data demonstrating the ability to remove apixaban from reconstituted blod by hemadsorption and are now analyzing if aFXa inhibitor levels may be reduced by hemadsorption in the clinical setting analyzing this in patients using FXa inhibitors being operated acutely for type A aortic dissection.
The introduction of thoracic endovascular aortic repair (TEVAR) in 1994 has radically changed the treatment of thoracic aortic pathology, and TEVAR is now the recommended therapy for "complicated" TBADs and other thoracic aorta diseases. To date, the use of TEVAR in the treatment of "uncomplicated" dissections (uTBAD) is uncertain, although it is presumed that a prophylactic procedure can prevent later complex surgery and early death. Several analyses have found that TEVAR confers improved aortic remodeling and possibly survival, although these were underpowered for this specific outcome. In addition, there are several reports regarding the uncertain benefit or harm of this intervention in the vascular surgery community. Put another way, there is equipoise, and the need for robust evidence in the form of a randomized clinical trial has been clearly iterated by the European Society of Vascular Surgery. This randomized, open-label, two-armed controlled study directly addresses this question of whether TEVAR alters 5-year survival among patients with an uTBAD. Patients will be randomized to either standard medical therapy (SMT) alone or TEVAR in addition to SMT. The primary outcome is 5-year survival, while secondary outcomes include aortic-related mortality, neurological events, quality of life, costs, re interventions and readmissions. in addition, subgroup analyses based on the extent of treatment. Sample size calculations based on previous reports indicate the need to include approximately 554 patients. Patients will be recruited from multiple centres in Scandinavia. Based on the population (24 million) and incidence of uTBAD (approximately 480 per year), and depending on the total number of participating centres, a conservative estimate of two to three years is required for enrolment.
The aim of the study is to determine which regional anaesthesiological technique (thoracic epidural analgesia or paravertebral block) is more suitable for thoracic surgery
Background: Aortic dissection (AD) is a common emergency in vascular surgery, which seriously threatens human life and health. The rupture of Stanford type B dissection is located in aortic arch and the dissection range is from the descending aorta or involves the abdominal aorta. At present, the endovascular repair of the thoracic aorta (TEVAR) for AD has been widely deployed worldwide and has become the standard surgical procedure for the treatment of AD. However, there is still controversy regarding the Stanford B aortic dissection that involves the left subclavian artery or the stent landing area less than 1.5 cm. Study objective: To evaluate the effectiveness and safety of endovascular repair with in situ needle fenestration of left subclavian artery. Methods: This study intends to enroll 217 patients with Stanford type B aortic dissection who meet the enrollment criteria. The patients will be followed up at 1, 6, 12, and 24 months after endovascular repair, and the CTA images of the thoracic aorta were collected.
Prospective, non-randomized, multicenter clinical investigation to assess the safety and effectiveness of AMDS in the treatment of patients with acute DeBakey type I dissection, with evidence of malperfusion, through open surgical repair.
This is an observational cohort study addressing the incidence of cerebral microemboli and alterations of cerebral hemodynamic physiology of the Relay®Branch thoracic stent-graft system.
