Filter by: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.
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.
Ischemia and reperfusion (I/R) injury during abdominal aortic aneurysm (AAA) repair is inevitable and may lead to postoperative multi-organ failure. Remote ischemic preconditioning (short periods of ischemia in anticipation of longer period of ischemia) may act protectively against ischemia. Studies of ischemic preconditioning in patients with AAA are conflicting. Obstructive sleep apnea (OSA) is a sleep disordered breathing syndrome which may have a protective effect against ischemia. The investigators hypothesize that I/R injury will be less pronounced in patients who have OSA and that the extent of I/R injury will inversely correlate with OSA severity. Accordingly, the aim of this study is to compare postoperative complications and markers of I/R in patients undergoing elective AAA repair who do and do not have OSA.
The objective of the proposed investigation is to assess the safety and effectiveness of the Merlin's DiVeRt system for the treatment of intracranial lesions. Merlin is a manufacturer of Flow- Diverters (FD) for Neurovascular applications. The technology is based on a microporous polymer membrane which is delivered to the site of lesion treatment using a metal stent scaffold. The first device in its FD family is the XCalibur Aneurysm Occlusion Device (AOD) system, which is delivered on a rapid-exchange balloon catheter which goes in a 6-Fr guide-catheter. The AOD is CE-marked and has been involved in the treatment of over 70 clinical lesion/aneurysm cases. The same technology is now being made available in a self-expandable stent platform delivered on a 0.028" microcatheter. Merlin has performed the required in-silico, in-vitro and in-vivo tests to be confident of the device performance and now intends to proceed to the human clinical-trials. DiVeRt (Interventional) is a non CE mark device. The device is under clinical trial phase. The competent authority submission for the study has been completed in Spain, Turkey and Hungary.
Abdominal aortic aneurysm (AAA) is a degenerative vascular disease, which is typically asymptomatic until rupture, resulting in high mortality. AAAs are more prevalent in men over age 65, though rupture is disproportionately higher in women. Due to nonlinear and unpredictable aortic dilatation, it is challenging to predict the AAA rupture using clinical diagnostics based on morphology. No medical therapy is used clinically to treat AAA, and there is an unmet need for clinically translatable, molecular biomarkers of AAA disease activity for surveillance and patient-specific management. The goal of this proposal is to develop a new approach for the diagnosis and targeted therapy of AAA.
This study aims to determine the inter- and intra-variability of Transcranial Doppler (TCD) ultrasound in neuro-critical care patients who are planned for consecutive daily TCD evaluations.
The protocol has many assets. A prospective nationwide recruitment allows for the inclusion of a large cohort of patients with UIA. It will combine accurate clinical phenotyping and comprehensive imaging with CAWE screening. Besides, it will enable to exploit metadata and to explore new pathophysiological pathways of interest by crossing clinical, genetic, biological, and imaging information.
This study aims to investigate the safety and efficacy of transcatheter exclusion of atrial septal aneurysm (ASA) via transseptal perforation in patients with ASA.
The purpose of this registry is to collect safety and performance data on all commercially available Terumo Aortic knitted and woven grafts, and cardiovascular patches in standard clinical practice. Data will be collected both retrospectively and prospectively.
