Filter by:Aortic disease is a life-threatening condition requires swift surgery or intervention. With modern techniques and vascular prostheses, still quite a few patients suffer surgery/intervention related complications such as suture line pseudoaneurysm, stent- induced re-entry tear, and aneurysmal expansion. Previous studies suggest that these complications may be related to the abnormal aortic motion pattern and biomechanical stress induced by vascular prostheses. The relationship between aortic motion changes and aortic adverse events after treatment still remains unclear. A dynamic protocol (multiphase contrast-enhanced ECG-gated) CT scan is able to measure the spatial motion of the ascending aorta, and finite element modelling is able to simulate both surgery or endovascular intervention and analyse the biomechanical interaction between vascular prostheses and tissue based on the patient-specific images. This project is aiming to explore and identify the interaction of 4D aortic motion and the biomechanical changes after surgery or endovascular treatment.
There are different case studies about the use of erector spinae block (ESPB ) in nephrectomy, but there are no enough randomized controlled studies about it until now so it will be one of the earliest studies that investigate the effect of ESPB to relief acute postoperative pain in patients undergoing open nephrectomy. Although ESPB and thoracic epidural analgesia blocks successfully reduced postoperative opioid consumption in previous studies, no study has ever compared their efficacy in postoperative analgesia of adult patients undergoing open nephrectomy under general anesthesia thus in this randomized comparative study we are aiming to fill this gap in the literature. The aim of this study is to compare the analgesic effect of ultrasound-guided continuous erector spinae plane block versus thoracic epidural analgesia in open nephrectomy for renal cancer patients.
This study was designed to whether there is a measurable reduction in inflammation in walls of unruptured vertebrobasilar dissecting aneurysms with atorvastatin.
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 and erector spina plane block (ESPB) are widely used for VATS. Among these methods, ultrasound (US) guided TPVB is the most preferred method. Generally, comparisons are made between ESPB and TPVB in studies and the analgesic effect is evaluated. However, no research could be found in the literature combining ESPB and TPVB. 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 TPVB and ESPB, as in the multimodal analgesia method. This study seeks to evaluate the effect of TPVB, ESPB and combined TPVB-ESPB pain after VATS.
A prospective, multi-center, objective performance criteria clinical trial to evaluate the safety and efficacy of Fabulous Stent Graft System manufactured by Hangzhou Endonom Medtech Co., Ltd. for Stanford B Aortic Dissection.
Anatomopathological classifications have been well identified in aortic dissection with important therapeutic implications. The authors evaluated the inflammatory response in patients with aortic dissection (AD) and assessed the presence of distinct inflammatory subphenotypes within this disease.
The aim of this study is to evaluate the analgesic efficacy of combined ultrasound (US)-guided pectoral nerve (PECS) block II and transversus thoracic plane (TTP) block versus US-guided serratus anterior plane (SAP) block in female patients undergoing modified radical mastectomy.
Aortic dissection is a life-threatening condition caused by a tear in the internal layer of major artery wall (aorta) that carries blood to all body organs, resulting in separation of the aortic wall layers (dissection). The dissected aorta compromises blood flow to any organ, and eventually leads to organ damage (Malperfusion Syndrome). Our goal in this project is to use Intravascular Ultrasound (IVUS) to have real time assessment and confirm any evidence of malperfusion syndrome in the setting of aortic dissection after repairing the original aortic tear. IVUS is a small ultrasound (sound waves) wand that is attached to the top of a thin tube. This tube is inserted into the aorta from the groin. This device takes pictures of the aorta and its major branches, to identify problems with blood flow. Having this real-time and dynamic assessment will help to identify any malperfused organs before leaving the operating room and allow us to address the malperfusion syndrome as quickly as possible to limit complications. Without this technique, identifying the problem can take several days after surgery at which point there can be irreversible complications.
Natural history multicenter, prospective, observational registry with 10-year follow-up
Background: The glycocalyx is a fundamental component of the endothelial barrier and alterations at this level have been shown to exacerbate the inflammatory response in the microcirculation. Its degradation in the surgical patient, has been tested in interventions that involve regional or general ischemia, for example in cardiac surgery, major vascular surgery or transplantation. On interventions that do not involve ischemic events the literature is limited, such is the case of those patients undergoing major abdominal and thoracic surgery. Objective: Assess whether there is a glycocalyx degradation in major elective abdominal and thoracic surgery, measured as an increase in plasma syndecane-1 levels during the first 24 hours of postoperative care. Methodology: Prospective observational study in patients undergoing major elective thoracic and abdominal surgery at the University Hospital Vall d´Hebrón. Measurement of the syndecane-1 plasma levels are going to be done during the first 24 hours after the intervention. It is intended to evaluate whether its elevation is related to anesthetic perioperative factors, and if it has an impact con morbildity and mortality in the following 6 months after the procedure.
