Filter by:Ongoing technological advances, especially in the field of image processing, have refined medical simulations to offer life-like replications of medical and surgical procedures in a variety of specialties. Patient-specific image data are incorporated into these simulations, and transformed into a 3D model. This enables the practitioner and his/her team to perform and practice 'real' cases on a virtual patient prior to performing the real procedure on the actual patient. This new technology has been referred to as 'patient-specific' rehearsal, also 'mission' or 'procedure' rehearsal. Research has already proven that simulated patient-specific rehearsal of a carotid artery stenting procedure may enhance surgical and team performance. The PROcedure rehearsal software can now also be used to practice patient-specific endovascular repair of infrarenal aortic aneurysms (EVAR). The ability to rehearse a challenging and complex procedure like EVAR may not only influence device selection based on preoperative planning, but also improve the technical performance of the surgeon/radiologist and the awareness and communication within the entire endovascular team. However, further research is needed to evaluate if this new technology may enhance clinical safety and efficiency, i.e. if patients actually benefit from physicians and team members conducting patient-specific rehearsals of EVAR interventions.
The main aim of this study will evaluate differences in serum levels of tryptase in study population. Will be selected a number of 350 patients hospitalized for coronary heart disease.
Many publications deal with the natural history of aortic aneurysms in literature. Except for connective tissue disorders as Marfan or Loeys-Dietz syndrome, aortic aneurysms are a complex multifactorial disease with genetic and environmental risk factors. Susceptibility loci identified in thoracic aortic aneurysms (TAA) and abdominal aortic aneurysms (AAA) do not overlap, suggesting that different genetic risk factors contribute to these two forms of aneuryms. With a higher prevalence correlated to ageing (5%), AAA is usually presented as the degenerative form of the disease. However, a recent epidemiologic study by Olsson et al. has revealed an increasing incidence of thoracic aortic disease among older individuals (70+/-12 years) with 60% of aneurysmal rupture or dissection at diagnosis, and a 1.7 :1 male-to-female ratio compared to 6:1 in AAA. From this current knowledge arises the concept of diffuse or plurisegmental degenerative aneurysmal aortic disease, poorly explored so far. As regards to the prevention policy, there is a consensus statement in which ultrasonography screening for AAA is recommended for all individuals aged > 60 years (particularly in men who have ever smoked) and for those aged > 50 years with family history of AAA. Nevertheless, screening for a concomittant thoracic location of the disease (except thoracoabdominal aneurysm) is not yet required, whereas it could change the prognosis of the patients and influence their management.
With evolving endovascular technologies there is a growing debate centered on the relative safety and efficacy of the currently accepted alternatives for the treatment of ruptured cerebral aneurysms in the face of acute subarachnoid hemorrhage (SAH). The purpose of this study is to compare the safety and efficacy of microsurgical clipping and endovascular coiling of acutely ruptured cerebral aneurysms in a prospective, randomized fashion.
The purpose of this study is to examine the risk factors for aneurysm rebleeding.
The primary objective of this study is to further expand the body of clinical knowledge in patients undergoing Pipeline Embolization Device (Pipeline or PED) placement for intracranial aneurysms (IAs or ICAs) according to Pipeline's labeled indication.
The purpose of this study is to evaluate the safety and probable benefit of the Low-profile Visualized Intraluminal Support (LVIS™ and LVIS™ Jr.)devices from MicroVention, Inc. when used to facilitate endovascular coiling of unruptured wide-neck intracranial aneurysms with bare platinum embolization coils.
The purpose of this registry is to obtain case reports of physician experience with the Spiral-Z® graft under routine clinical care.
The primary objectives of this study are to determine whether physician modified endovascular grafts are a safe and effective method of treating patients with elective, symptomatic or ruptured juxtarenal aortic aneurysms in those patients considered to be unsuitable candidates for open surgical repair and have no other options for treatment.
The ANCHOR registry is a multi-center, post-market, non-interventional, non-randomized, prospective study. Subjects must sign an ICF prior to obtaining any study specific information. Subjects are eligible to be consented up to 30 days post-procedure. Enrolled subjects will be followed as per local 'standard of care' for up to 5 years post procedure. Study recommended follow-up is per SVS and ESVS guidance.
