Filter by:Among patients who have undergone EVAR, there is a significant risk of 20-50% endoleak. These endoleaks often require secondary interventions to reduce the risk of expansion or rupture. Currently, three-phase CT angiography and CEUS ultrasound are recommended in the post-operative monitoring of EVAR but these remain limited in characterizing the type and source of endoleak. In this study the investigators will study the interest of d-CTA for a better detection and characterization of endoleaks.
The goal of this registry is to evaluate the semibranch in branched endovascular aortic repair, which is a new tool in endovascular branched aortic repair.
Beyond a certain threshold diameter, Abdominal aortic aneurysms (AAA) are treated by open surgical repair or, more often by endovascular aortic aneurysm repair (EVAR). The latter involves implantation of a stent-graft and thereby exclusion of the AAA from the blood circuit. Small vessels supplying parts of the bowel or the spine are regularly covered. In a quarter of patients, this may result in an inversion of blood flow in the mentioned vessels, leading to persistent blood flow within the AAA, referred to as type II endoleak (T2EL). Occurrence of T2EL is associated with complications like AAA growth or even rupture. Secondary interventions to treat T2EL often fail and may be highly invasive. Various risk factors for T2EL have been described. This enables prediction whether a patient is at high risk for T2EL after EVAR. Deployment of metal coils in the aneurysm sac as part of the EVAR procedure can reduce the risk for T2EL.The present study aims to assess the efficacy of sac embolization during EVAR to prevent T2EL.
The ENDOBARC-S post-market clinical follow-up study is undertaken to evaluate the prevention of death related to aortic arch pathologies when treated by branch stent graft systems (Nexus stent-graft system®, Relay Branch® or Zenith arch branch graft®), with proximal landing at zone 0. The secondary objective is to evaluate the safety and clinical performance of the studied devices.
Advanced Endovascular repair of aneurysms and dissections involving thoraco-abdominal (type I-IV) and complex abdominal (juxta and para-renal) aorta is a ground-gaining procedure allowing favorable results in high surgical risk patients. The availability of iliac vessels navigation and the major role of lower leg perfusion in order to decrease the risk of spinal cord ischemia during these complex procedures, led to the development of devices with lower sheaths sizes and to the improvement of the technique with preloaded devices for visceral vessels in order to navigate in hostile anatomies or when an iliac access is not available. The aim of the study is to evaluate in a prospective single center observational setting, the outcomes, safety and efficacy of the modified preloaded system for renal arteries in fenestrated endografting in the routine treatment of paravisceral and thoraco-abdominal aortic pathologies.
The study is non-randomized, multicenter international safety, performance and clinical benefit outcome assessment of ANEUFIX to treat patients with isolated type II endoleak in the presence of a growing AAA-sac following an EVAR procedure more than 6 months ago.
