Filter by:A prospective clinical evaluation of the effectiveness of the Ovation Alto Abdominal Stent Graft System when used in the treatment of subjects with abdominal aortic aneurysm (AAA).
This study will evaluate a randomized comparison of direct versus snare techniques for cannulation of contralateral gate during an endovascular aneurysm repair (EVAR) procedure. This information will be used to determine if primary snaring is superior to retrograde cannulation in decreasing procedural time and radiation exposure.
A prospective, multicenter, observational assessment of the safety and effectiveness of the LVIS® device in the treatment of wide necked intracranial aneurysms.
A prospective, multicenter, observational evaluation of the safety and efficacy of the FRED® device in the treatment of intracranial aneurysms.
This trial is conducted to evaluate the safety and technical effectiveness of using NCVC-CS1, a newly developed honeycomb microporous covered stent, for the treatment of intracranial aneurysms which are difficult to be cured by conventional surgical or endovascular procedures.
Vitamin D has been shown to impact prognosis in a variety of retrospective and randomized clinical trials within an intensive care unit (ICU) environment. Despite these findings, there have been no studies examining the impact of hypovitaminosis D in specialized neurocritical care units (NCCU). Given the often significant differences in the management of patients in NCCU and more generalized intensive care units there is a need for further inquiries into the impact of low vitamin D levels in this specific environment. This study proposes a randomized, double-blinded, placebo-controlled, single center evaluation of vitamin D supplementation in the emergent NCCU patient population. The primary outcome will involve length-of-stay for emergent neurocritical care patients. Various secondary outcomes, including in-hospital mortality, ICU length-of-stay, Glasgow Outcome Score on discharge, complications and quality-of-life metrics. Patients will be followed for 6 months post-discharge.
The aim of this prospective, explorative study of noninvasive neuromonitoring was to search potential and practical methods associated with neurological outcome in the perioperative and immediate postoperative setting of surgery of the thoracic aorta. These methods include abbreviated EEG monitoring, near-infrared spectroscopy, transcranial Doppler ultrasound and biochemical markers associated with neuronal damage.
Screening for an abdominal aortic aneurysm, monitoring its growth and evaluation of its risk of rupture are based on the measure of its maximum diameter. The abdominal aortic aneurysm's treatment to prevent its rupture is recommended from a threshold of 50-55 mm in men and of 45-50 mm in women. The importance of this measure for patient management justify a specific and homogeneous protocol of measure. However, the diversity of methods of measuring the maximum diameter with scanner and ultrasound was shown. The impact of various angio-CT based measures of maximum AAA diameter, and the impact of reproducibility limits on the decision to operate have never been investigated.
The aim of the study is to assess if venous distension in patients with aneurysmatic arteriopathy is higher compared to patients with peripheral arterial occlusive disease (PAOD) and in controls.
During the last decade, the embolization has become the treatment of choice for ruptured intracranial aneurysms, to improve the neurological outcome of patients. At the same time, for his safety, she also became the technique allowing prophylactic treatment of unruptured intracranial aneurysms discovered incidentally during imaging exams. Regarding patients with ruptured intracranial aneurysms, patients who survive often have a reduced quality of life while one in two has a good neurological outcome after embolization. Depression, anxiety and fatigue, whose the psycho-social impact is important, are often cited. This description has often been done without considering the realized type of treatment (surgery or embolization) and mostly of neurological and functional status of the patient remotely (disability or not in daily activities). Regarding patients with unruptured intracranial aneurysms, they are mostly asymptomatic and embolization is programmed. They would present an cognitive impairment in one case in five at 1 month of treatment. If depression, fatigue and difficult return to working life are logically found in patients with severe sequelae (disability in daily activities) of their ruptured intracranial aneurysms, the question arises for patients with a ruptured intracranial aneurysms with a favorable evolution and for asymptomatic patients with unruptured intracranial aneurysms. A precise status of these populations is necessary, especially as the discovery and treatment of their intracranial aneurysms is often early (between 40 and 60 years) and that their good neurological status should allow "a priori" to return easily at the active life.
