The results of this study will serve as a starting point for future trials concentrating on the effectiveness and clinical outcomes of the procedures performed in an office based angiosuite. Additionally, other studies could compare clinical outcomes between procedures performed in an office based angiosuite and other settings.
To evaluate the safety and accuracy of the Saranas EBBMS for the detection of access site related internal bleeding events during large-bore endovascular procedures.
As endovascular procedures become more complex, there is a growing need for 3D image overlay to assist with device guidance and placement. Currently, a 3D image is typically created intra-operatively using 3D rotational angiography (3D-RA) or cone-beam CT (XperCT). This 3D image may then be overlaid on live fluoroscopy to provide 3D guidance information (Dynamic 3D Roadmapping). Philips Healthcare multimodality overlay products allows registration of a pre-acquired MR/CT or 3D rotational image to live fluoroscopy.
In chronic CLI patients who are appropriate candidates for endovascular procedures - and many patients are not because of their advanced age and disease state - the treatment regimen may include endovascular procedures such as percutaneous transluminal endovascular intervention, as well as reconstructive surgical procedures such as grafts or bypasses. Amputation is a last resort where limb salvage cannot be achieved. Despite the success of percutaneous intervention for small coronary vessels with lumen diameters less than 3 mm, similar techniques have had limited success in the lower extremity vessels. Infra-popliteal, or below the knee endovascular intervention, is commonly plagued by subacute thrombotic closure and restenosis in as many as 50% of treated patients. As a result of the limited success, these percutaneous procedures have been reserved for the severest cases whereby limb loss is imminent without intervention. In this context, the sickest of all patients are enrolled in these trials and poor outcomes are common regardless of the intervention. Agents that promote intracellular cAMP accumulation, including prostacyclin analogues and phosphodiesterase inhibitors, suppress smooth muscle proliferation, promote vasodilatation and inhibit platelet aggregation. These properties suggest that prostacyclin analogues such as treprostinil will be useful adjuncts to peripheral endovascular intervention and perhaps increase the number of patients with CLI that can benefit from peripheral endovascular intervention. An orally available prostacyclin analogue could represent an important treatment advance in the prevention of restenosis following infrapopliteal angioplasty. In the present study, the safety and efficacy of oral UT-15C sustained release (SR) tablets will be compared to placebo in patients with CLI undergoing an infra-popliteal endovascular intervention.
Evaluate wound healing using Prevena compared to standard dressings in high risk patients after vascular surgery.
The primary objective of the trial is to evaluate short versus long duration dual antiplatelet therapy in patients undergoing lower extremity endovascular revascularization.
This is a study to evaluate the hypothesis that FDA cleared thrombectomy devices plus medical management leads to superior clinical outcomes in acute ischemic stroke patients at 90 days when compared to medical management alone in appropriately selected subjects with the Target mismatch profile and an MCA (M1 segment) or ICA occlusion who can be randomized and have endovascular treatment initiated between 6-16 hours after last seen well.
Investigators hypothesize that high-dose n-3 polyunsaturated fatty acids (PUFA) oral supplementation will improve will improve systemic inflammation and patency of peripheral vascular intervention (PVI).
XLPAD is an observational study designed to evaluate the effectiveness and use of stent and non-stent based therapies among PAD patients. The study will create a registry that will include entry of procedural and clinical follow-up information into an online data collection software, REDCAP.Data available since Jan 1 2005 will be included in the registry, until 14,000 patients have been included. The primary objectives of this observational registry study are to: 1. Compare stent and non-stent based outcomes defined as a composite of symptom driven target vessel revascularization (TVR), unplanned surgical revascularization of the target limb and need for target limb amputation through 12 months post-index procedure (Primary efficacy endpoint) 2. Compare stent and non-stent based outcomes defined as a composite of causes such as: death, myocardial infarction (MI), stroke, peri-procedural complications, target vessel revascularization (TVR) and unplanned surgical revascularization/amputation of the target limb through 12 months (Primary safety endpoint) 3. Compare stent and non-stent based change in walking distance, Rutherford category and/or ankle- brachial index (ABI) at 12 months compared to baseline (Primary clinical improvement endpoint) Approximately 14,000patients will be enrolled at approximately 60 sites worldwide. Enrollment in the observational study will be monitored in an effort to achieve at least 20% (and no more than 80%) of the population receiving stents as the initial treatment strategy. Follow-up visits by sites will be reported at 6 and 12 months after index procedure to collect data on treatment patterns and effectiveness, and outcomes. The follow-up procedures are not mandated by the registry protocol. Each site will be encouraged to enter follow-up information derived from clinically indicated follow-up visits. All events post-index procedure till the 7th month will be reported under the 6 month follow-up form and subsequent follow-up till the 13th month post-procedure will be entered on the 12 month follow-up form. Patient management and treatment decisions are at the discretion of the care team per routine clinical practice. The procedural aspects (including selection of stent type or non-stent based treatments) and follow-up are not mandated by the registry and will be up to the discretion of the operator and/or based upon the practice dictated by the clinical care of the patient. Therefore the study poses minimal risk to the patient.
Dexmedetomidine is a unique sedative medication able to provide sedation without causing respiratory depression and maintaining neurological functions. Patients having an acute ischemic stroke and need to undergo endovascular therapy require constant assessment of their neurological status prior, during and after the interventional procedure. In this study the investigators will compare the efficacy of Dexmedetomidine to other standard sedative medications in providing optimal sedative effect while maintaining neurological function.
The objective of this trial is to demonstrate the safety and effectiveness of the Cardiva VASCADE™ Vascular Closure System (VCS) in sealing femoral arterial access sites. Hypothesis: The Cardiva VASCADE™ VCS provides times to hemostasis (TTH) and time to ambulation (TTA) results that are less than manual compression by a clinically meaningful and statistically significant margin. The rate of major access site-related complications with the Cardiva VASCADE™ VCS is non-inferior to the major complication rates of manual compression for sealing femoral arterial access sites.
The Mynx Vascular Closure Device (Mynx M5) is a sponge-like material used to close the hole in the artery after patients undergo a diagnostic endovascular procedures
This study was designed to study safety and effectiveness of the Valiant Thoracic Stent Graft to treat thoracic aortic aneurysms.
The aim of the study is to evaluate the outcomes of the preloaded stent-graft design (PLD) in the routine treatment of para-renal and thoraco-abdominal aneurysms. Results and postoperative events are reported in accordance with the current reporting standards for endovascular aortic repair prepared and revised by the Ad Hoc Committee for Standardized Reporting Practices in Vascular Surgery of The Society for Vascular Surgery/American Association for Vascular Surgery. The Registry will include approximately 300 patients treated from January 2015 to May 2021 (retrospective arm) and June 2021 to June 2023 (perspective arm) for the routine treatment of para-renal and thoraco-abdominal aneurysms. To reach 300 patients, the enrollments can be extended until June 2026.
Pseudotumor cerebri, also called idiopathic intracranial hypertension (IIH), is characterized by elevated intracranial pressure, headache, and if severe, vision loss. IIH is difficult to treat. Medical management may not adequately resolve the symptoms, and surgical management (primarily through cerebrospinal fluid \[CSF\] shunting) has a high failure rate. Recently, a relationship between IIH and stenosis of the dural venous sinuses (the veins that drain blood from the brain) has been reported. In patients with IIH in whom there is stenosis of one or more dural venous sinuses, placing a stent in the venous sinus may improve patients' objective symptoms (such as visual loss and papilledema) and subjective symptoms (such as headache). This study will determine whether dural venous sinus stenting is as effective as CSF shunting (considered the standard surgical treatment) in treating IIH patients who have moderate vision loss and stenosis of the dural venous sinuses.
The PATHFINDER I Registry is a prospective, non-randomized, single arm, multicenter observational study. It is a pilot registry study towards a subsequent large pivotal phase registry. This pilot registry is aimed to evaluate the performance (peri-procedural) and clinical outcomes (intermediate and long-term) of the AURYON™ Atherectomy System, within the initial launch phase of the product in the market.
The purpose of this study is to evaluate the procedural and clinical benefits of patient specific pre-procedure rehearsal for operators with various experience levels as a tool for optimizing Endovascular Aneurysm Repair (EVAR) procedures.
