Filter by:The use of intracranial stents expands the possibilities for endovascular treatment of intracranial aneurysms and improves the success rate. However, it also increases the risk of ischemic complications in patients. The current standard dual antiplatelet regimen is considered crucial in reducing thrombotic events. Nevertheless, some patients exhibit resistance to antiplatelet drugs, which puts them at a higher risk of thrombotic events. In clinical practice, there is a lack of standardized platelet function testing and consensus on adjusting antiplatelet drug programs. This study conducted a multi-center, prospective cluster randomized controlled trial to investigate whether antiplatelet adjustment therapy guided by light transmittance aggregometry (LTA) detection can decrease the occurrence of ischemic events after stent implantation in patients with unruptured intracranial aneurysms. Additionally, the study aimed to establish a set of standardized antiplatelet regimens.
This is a multicenter, observational, prospective, single arm registry using Ovation Alto Endograft. A minimum of 50 up to a maximum of 120 subjects undergoing endovascular repair with Ovation Alto endograft will be enrolled and followed procedurally to discharge, at 1month, 6 months, 1 year and yearly afterward up to 3 years. This registry of Ovation Alto endograft will provide further assessment to confirm continuing safety and effectiveness of the graft and to confirm the stability of the neck diameter over time when treated with this device.
Single center, open label, prospective, single-arm, first-in-human (FIH), pre-market clinical study with the objective of validating the safety and performance of the Suture-Tight™ Suture Delivery System in an EVAR procedure.
We study differen t endovascular techniques as an alternative to surgical reconstruction to repair AAAS regarding ; success rates, 30-day mortality, endoleak events secondary intervention rates
the goal of this clinical trail is to evaluate the clinical efficiency of intracranial aneurysm assistive software in the morphological measurement. The trail is designed as retrospective, multicenter, controlled clinical trail. Collecting probable cases images retrospectively according to inclusion criteria and exclusion criteria strictly. Controlling bias strictly, to make sure the measurement of intracranial aneurysm assistive software is evaluated reliably and precisely. In our trail, six physicions were recruited, containing three neuroradiologists, two radiologists and a residents. Software-assistant planning controls against no software-assisant planning，which aims to evaluate the improvement of morphological measurement efficiency of physicians.
A First in man study to evaluate the safety and efficacy of thoracoabdominal aortic stent system for endovascular treatment of thoracoabdominal aortic dissecting aneurysm.
The primary objective of ARISE II is to assess the safety and effectiveness of the GORE® Ascending Stent Graft device in the treatment of lesions involving the ascending aorta and aortic arch.
Intracranial aneurysm (IA) is a cerebrovascular disorder in which the weakness of a cerebral artery wall causes a localized dilation of the blood vessel. Intracranial aneurysm can develop and rupture, and about 85% of spontaneous subarachnoid hemorrhage (SAH) cases are caused by the rupture of Intracerebral aneurysm. Two treatments are available globally: microsurgical clipping and endovascular treatment. Endovascular treatment of Intracerebral aneurysms using detachable platinum coils ( was introduced in 1990 by Guido Guglielmi, an Italian neurosurgeon ) of different shapes and sizes are deposited into the aneurysm through a microcatheter, which reduces the blood flow and induces thrombus formation . Wide neck aneurysm defined by neck diameter greater than 4 mm or dome-to-neck ratio less than 2 Despite advances in endovascular techniques , the treatment of wide-necked aneurysms remains problematic . Endovascular treatment of intracranial aneurysms is associated with lower morbidity and mortality rates and faster recovery compared with traditional microsurgical clipping. In wide-necked Intracerebral aneurysms, complete coil embolization is often technically difficult owing to the risks of distal coil migration or coil impingement on the parent vessel . Complete coil embolization using a single microcatheter without a supporting device in cases of wide-necked Intracerebral aneurysm is technically difficult. Total occlusion rates have increased recently as a result of the advancement of supporting devices These may include balloon remodeling, use of three-dimensional (3D) coils (Russian Doll Technique), combined use of stents and coils (Stent assisted coiling), flow diverters, use of intrasaccular flow disruption (like WEB), Double catheter Technique or combined extra- and intrasaccular devices.
This study aims to evaluate mid- and long-term outcomes after Thoracic endovascular aortic repair (TEVAR) with custom-made devices.
The term mycotic aneurysm (MA) is commonly used to describe all infected aneurysms. Although MAs are believed to occur uncommonly, the true incidence is difficult to determine and is probably underestimated since MAs can be asymptomatic and are diagnosed only at autopsy. In an autoptic study, mycotic aortic aneurysms (MAAs) were reported in 3.3% of all detected aneurysms. The incidence of infected aneurysms of the aorta and iliac arteries ranges from 0.6% to 1.3%. A recent literature review of the management of MAAs showed that therapeutic strategies are multiple, including open surgical repair (OSR) in the majority of cases, endovascular aortic repair (EVAR), which increased over the last decade, and medical treatment alone for patients unfit for any aortic repair in a very limited part. Following the unfavorable prognosis towards rupture and since the medical treatment alone in mycotic aneurysms has shown mortality of almost 100%, surgical treatment is generally the preferred option. Surgical treatment includes both open and endovascular surgery. The latter is less invasive than conventional surgery but does not involve resection of the infected tissue and is therefore associated with an increased risk of sepsis and prosthesis infection. The gold standard is still open surgery, including extra-anatomic reconstruction and in situ repair, with different type of vascular graft. This is a multicenter retrospective observational study. It will examine all patients undergoing surgical treatment of mycotic aortic-iliac aneurysms and in situ reconstruction at the participating centers.
