View clinical trials related to Iliac Artery Disease.
Filter by:Atherosclerosis can cause the arteries to narrow (stenosis) or clog (occlude), leading to reduced blood flow. Arteriography or angiography is a radiological examination of the arteries which will make it possible to confirm and quantify the severity of the damage to the artery and which, in certain cases, can be directly treated by angioplasty with or without stenting (selective angioplasty). Digital subtraction angiography (DSA), the reference technique, provides good image quality. The fluoroscopy used today during angioplasty procedures makes it possible to obtain images in real time and to guide the progression of the endovascular material in the arterial axis. Image fusion is an established technique for the endovascular treatment of aortic aneurysms. The feasibility of image fusion for the iliac arterial axes has already been assessed and is reproducible. However, there is no assessment of the irradiation rate in iliac angioplasty, using intraoperative image fusion, compared to standard angioplasty practices.
The research objectives of this project are to increase the understanding of pathophysiology and performance limitations related to sport-related flow limitation in the iliac artery (FLIA) using non-invasive measurement of muscle oxygenation at the working muscles of the leg and mechanical power output recorded during cycling exercise. Skeletal muscle oxygenation measured with Near-Infrared Spectroscopy (NIRS) is growing more accessible for use by coaches, teams, and individual athletes for use in performance testing. Describing how muscle oxygenation profiles in endurance athletes diagnosed with FLIA differ in comparison with healthy athletes may allow the use of this non-invasive, accessible measurement device for the screening of athletes at risk of developing FLIA. The relevance of this work is that FLIA imposes risk of irreversible injury to the main artery of the leg in endurance athletes, limiting their ability to participate in exercise, with further consequences for health, fitness, and quality of life. Currently, the early course of this progressive condition is poorly understood, as early detection is difficult and hence appropriate treatment is often delayed. If impairment becomes severe, often more invasive (and risky) treatment is necessary. Earlier detection and monitoring of FLIA may allow for improved patient management and outcomes. The design of this experiment will compare a patient group of trained cyclists diagnosed with FLIA, to healthy control subjects including cyclists of a similar fitness level without signs of FLIA. Both groups will perform an incremental ramp cycling test and an intermittent multi-stage cycling exercise test. Incremental ramp cycling testing is used as part of clinical diagnosis of FLIA, as well as performance (eg. VO2max) testing of healthy athletes. Multi-stage exercise protocols are also often used for performance testing of endurance athletes and allows for observation of (path)physiological responses during submaximal work stages. Outcome measures of muscle oxygenation kinetics with NIRS and cycling power will be analysed and compared between patients and healthy subjects.
The objective of this prospective, multicenter, non-randomized, single-arm observational study is to evaluate the efficacy and the safety of the iCover covered stent for the treatment of de novo aorto-iliac atherosclerotic lesions in patients with symptomatic arteriopathy of the lower limbs (Rutherford class 2 to 5).
This PMCF study is designed as prospective, multi-center study to collect real-life data. The rationale of this study is to confirm and support the clinical safety and performance of the aforementioned products in 200 patients who will undergo an endovascular intervention within standard-of-care (SOC) where at least 1 of the following devices from AndraTec were used: The LOKUM-Quest guidewire, The LOKUM AMPLATZ guidewire, the Slider Hydrophilic Nitinol Guidewire, the AltoSa-XL PTA balloon, the AltoSa-XL GEMINI PTA Balloon, the OPTIMUS CoCr Stent , the OPTIMUS-CVS PTFE-Covered stent.
This is a prospective, single-center, non-randomized phase 2, first-in-iliac artery study, to evaluate the safety and effectiveness of the WRAPSODY Stent Graft for the treatment of peripheral arterial occlusive disease in symptomatic subjects with de novo or restenotic lesions in the common iliac artery (CIA) and/or external iliac artery (EIA), including lesions at the aortic bifurcation.
This study compares early and long-term results of the endovascular treatment among patients with different types of aorto-iliac occlusions.
This study evaluates the local inflammatory and resolution response of patients undergoing peripheral vascular intervention like an angioplasty of the superficial femoral artery (SFA) or popliteal artery, or stenting of the iliac artery or SFA, through the use of Positron emission tomography-magnetic resonance imaging (PET/MRI). PET/MRI will be performed prior to intervention, one day and one week after intervention.
The purpose of this observational study is to evaluate the performance and safety of endovascular treatment with stenting (Optimed Sinus Superflex 635 or Qualimed Pontos-pp) or balloon angioplasty (Cardionovum Legflow or Optimed Nylotrack .035 + .018) according to current practice. The goal of the study will be achieved by assessing binary restenosis with duplex ultrasound, peri- and postoperative complications, technical success, target lesion revascularization, amputation and clinical outcome.
