Filter by:The goal of this registry is to evaluate the semibranch in branched endovascular arotic repair, which is a new tool in endovascular branched aortic repair.
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.
Proximal type 1A endoleak is a worrying complication after endovascular repair of an abdominal aortic aneurysm (EVAR). The ideal solution is not obvious between relining by FEVAR and endograft explantation. A retrospective french multicentric study was performed between 2010 and 2023 to compare the outcomes and the efficiency of both technics and propose a decision algorithm for the management of type 1A endoleak after EVAR.
The objective of the study is to collect and evaluate clinical data on patients of the Lifetech Cera™ Vascular Plug System to: - confirm the performance - confirm the safety - identify previously unknown side-effects - monitor the identified side-effects (related to the procedures or to the medical devices) - identify and analyse emergent risks

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.
To determine the safety and efficacy of IMPEDE-FX Embolization Plug and/or IMPEDE-FX Rapid Fill to fill an abdominal aortic aneurysm (AAA) sac outside of an endovascular aneurysm repair (EVAR) stent graft.
Surgery for abdominal aortic pathology usually occurs in the setting of advanced cardiovascular disease. The repair can be relatively simple or complex with multiple steps including open repair, placing a stent with a catheter, and placing a complicated stent that allows for crossing vessels without occluding them. All these repairs require imaging follow up. The most commonly accepted tool for follow up is Computed Tomography (CT) scan which involves ionizing radiation and potentially nephrotoxic iodinated contrast. Recommendations for the time interval for follow up, as well the radiology imaging technique vary. Routine ultrasound with Doppler, CT, and MRI has all been employed utilizing various imaging protocols. Clinicians use non-contrast CT, arterial phase and delayed phase CT, ultrasound, and various combinations based on personal experience and patient pathology. Concerns over cost, potential nephrotoxicity of contrast agents and repeated radiation exposure has led to investigation of alternate imaging modalities such as contrast-enhanced ultrasound (CEUS). CEUS represents an improvement of ultrasound imaging but comparisons against CT report widely varying results, likely due to technical factors of CEUS and limitations of single-phase CTA. Contrast ultrasound has been used effectively to diagnose leaks in the aorta post repair and is without the radiation and potential nephrotoxicity of iodinated contrast. Of yet, no large prospective studies have compared CT and contrast US and no studies have looked at the more complicated staged or fenestrated repairs. This study proposes to perform a contrast ultrasound at the same time as a contrast CT using a standardized protocol. This protocol would include a non-contrast CT, angiographic CT, and a CT in a delayed phase in all patients as standard of care. We will compare the results of a contrast US with the various data derived from a three phase CT.
