The main purpose of this study is to determine if PET-imaging can be used to evaluate inflammation level of intracranial aneurysms, thus helping to evaluate the rupture risk of intracranial aneurysm.
The aim of this retrospective, multicenter study is to demonstrate that the use of EndoNaut for aortoiliac endovascular procedures has a clinical impact for the patient (reduction in irradiation and the volume of contrast product) as well as for the nursing staff (reduction irradiation) compared to procedures performed without EndoNaut.
The purpose of this study is to determine the long-term performance of the TREO Abdominal Stent-Graft as a treatment for patients with Infrarenal Abdominal Aortic Aneurysms or Aorto-iliac Aneurysms.
The aim of the study is to test the effectiveness and safety of the use of lidocaine infusion in multimodal analgesic management. A group of patients undergoing vascular surgery performed with the classic technique on the aorta - with the opening of the abdominal cavity will be enrolled. The population of patients qualified for this type of vascular surgery is usually burdened with multiple diseases, mainly risk factors or cardiovascular diseases, which, combined with hemodynamic fluctuations, large fluid shifts (including bleeding) and stress for the body, affects the risk of serious cardiological complications, which in this group exceeds 5% and is the highest, according to the ESC / ESA (European Society of Cardiology / European Society of Anesthesiology) classification from 2014. Proper postoperative pain control is therefore becoming one of the key pillars of postoperative care in this group of patients. Due to the numerous disease burden of patients and the operational specifics, the use of multimodal therapy in the management of pain is of particular importance, as the use of high doses of opioids improves hemodynamic stability, but at the same time affects the occurrence of side effects - mainly excessive sedation, respiratory disorders, hypoventilation and, consequently, for hypoxia of the heart muscle. The risk of myocardial injury in non-cardiac surgery (MINS) is significant in the light of the available literature. Lidocaine used in intravenous infusion is one of the recommended components of multidirectional analgesia. Its adjuvant properties make it possible to reduce the amount of opioid drugs used, and thus - to reduce the frequency of their side effects. The high effectiveness of such a procedure has been proven in numerous experimental and epidemiological studies. Due to the low frequency of side effects associated with its use, the therapy has a strong recommendation for use in relieving perioperative pain. The analysis of the literature on the subject shows that there is little data assessing effectiveness of lidocaine infusion in relation to the group of patients after surgery on the abdominal aorta.
Biomarkers can play a vital role in prognosing the perioperative complications in thoracic aorta surgery. The goal of a study is to determine the correlation between intraoperative level of certain biomarkers and total amount of peroperative complications.
Primary dysmenorrhea (PD) is defined as recurrent, crampy pain occurring with menses in the absence of identifiable pelvic pathology. Standard initial management of PD includes NSAIDs as a first-line treatment and oral contraceptives for the relief of pain and improved daily activity. In patients who have persistent dysmenorrhea despite medical therapy of NSAIDs and/or oral contraceptives, further investigation including pelvic ultrasound, hysteroscopy or laparoscopy may be needed to rule out other underlying pathologies. Historically, It is an old clinical observation that primary dysmenorrhea is often completely or partially relieved by childbearing. Similarly, the investigators have observed that the diagnostic/operative hysteroscopy led to relive of pain in most of the cases in our practice. Therefore, the investigators hypothesized that the process of cervical dilatation can have a role in reducing pain of patients with dysmenorrhea. In this randomized, controlled study, it was aimed to assess the effect of operational cervical dilatation on the pain in patients with primary dysmenorrhea.
The NEOS post-market clinical follow-up study is undertaken to demonstrate the safety and clinical performance of E-vita OPEN NEO in the treatment of aneurysm or dissection in the ascending aorta, aortic arch and descending thoracic aorta.
Introduction: Complex abdominal aortic aneurysms (CAA) are defined as abdominal aneurysms that are anatomically unsuitable for a standard endovascular repair because of a short infrarenal neck or no infrarenal neck. These CAAA are usually treated either by fenestrated endovascular aortic repair (FEVAR) or open repair (OR). Data comparing these thechniques remain scarce, mainly consisting of systematic reviews based on retrospective studies. Although mid-term and long-term results remain uncertain, FEVAR has gained widespread acceptance in the vascular community. However, this practice is not evidence base. Beyond clinical results, whether FEVAR is cost-effective or not is not demonstrated. A randomized controlled trial comparing FEVAR and OR is unlikely to be conducted since centers have developed specific expertise and practice, and most of surgeons are not keen to randomize patients. Thus, we believe that a prospective comparative multicentric cohort, with a propensity score and minimization of selection, classification and confusion bias is the most realistic way to provide reliable comparative data on cost effectiveness of FEVAR and OR. Overall, 382 patients are expected to be included (159 in each group). Objective: The objective of this prospective non-randomized comparative multicenter cohort study is to compare the cost effectiveness incremental ratio at 36 months of FEVAR and OR for CAAA. Method: Patients with CAAA discussed for FEVAR or OR in 37 french vascular centers in during a two years inclusion period constitute the population study. Preoperative and postoperative clinical and imaging data will are collected prospectively in eCRF forms. QOL before and after treatment is assessed by the E5D5L. The follow-up period is three years. The primary outcome is the Incremental cost-utility ratio (cost/QALY) at 36 months. We plan to minimize indication biases by using a proposensity score (proposnsity score maching and Inverse probablility of treatment weighting) based on clinical and anatomic characteristics. Patient at prohibitive risk for OR are excluded. Patient anatomically unsuitable for FEVAR are also excluded . Conclusion: This study should provided valuable data on cost effectiveness of FEVAR for CAAA. Sub-goup analysis will be also conducted.
The study aims to investigate the applicability of intravascular ultrasound (IVUS) in the endovascular therapy of juxta-, supra- and thoracoabdominal aortic aneurysms. The focus of the study is on the intraoperative and postoperative evaluation of the geometric data of bridging stentgrafts in terms of patency, occurrence of stenosis and/or kinking.
