Active clinical trials for "Peripheral Vascular Diseases"

Feasibility Study of the Vessel Restoration System (VRS) for the Treatment of Atherosclerotic Lesions in the Superficial Femoral Artery (SFA) and/or Proximal Popliteal Artery (PPA): ACTIVATE II

This study aims to evaluate the effectiveness and safety of the Smart flex stent system in treating long femoropopliteal native lesions.

Over the past decade, interventional endovascular treatment, whenever feasible, has become the first line management in the treatment of lower extremity arterial disease (LEAD) for many indications. Growth of endovascular therapy was based on shorter hospital length of stay and lower complications rates. This minimally invasive procedure allows the revascularization of the lower limbs under fluoroscopy guidance, with injection of iodinated contrast allowing to analyze the arteries. However, many of these patients present renal insufficiency which could be worsened due to the iodinated contrast injections during the endovascular procedure for LEAD. Consequently, the vascular interventionalist should find a way to achieve patient revascularization while minimizing iodinated contrast injections in order to maintain the renal function. The aim of this study is to compare the amount of iodine contrast used during LEAD endovascular revascularization with and without the Innova Breeze® and blended roadmap software.

In this study, we will explore how ultrasound exposure of ultrasound contrast agents, which produces beneficial shear-mediated bioeffects, can be used to treat patients with severe non-healing ulcers secondary to peripheral arterial disease (PAD). The primary outcome measure is whether ultrasound exposure to microbubble contrast agents in the inflow artery and at the wound site can accelerate wound healing. A secondary outcome measure is whether cavitation-related changes occur in tissue perfusion in the treated limb and wound measured by ultrasound perfusion imaging and skin flow.

This is a prospective, single-center and single-arm clinical study to assess the initial safety and effectiveness of the Kaitoh Atherectomy System for the treatment of de novo and/or restenotic lesion(s) in the peripheral arteries.

To evaluate the efficacy and safety of peripheral shock catheter system in peripheral arterial angioplasty.This trial is a prospective, multicenter, open, randomized, parallel controlled and superior clinical trial. Select ≥3 hospitals with the qualification of national clinical trial institutions as clinical trial centers, and plan to enroll a total of 120 subjects. The ratio of subjects in the trial group and the control group is 1: 1 (60 in the trial group and 60 in the control group). This study mainly includes four stages: the screening (baseline) period (-14 ~0 days), the operation day (the day of treatment), the postoperative visit (0~7days ) and the 30-day follow-up (30 ±7days ).

This study is designed to evaluate the efficacy (device deployment characteristics and performance) and safety (adverse access site related events) of Perclose ProGlide (Abbott Vascular Devices) for femoral access site closure in patients undergoing peripheral vascular diagnostic and interventional procedures in comparison with Angio-seal VIP (St. Jude Medical).

Sympathetic overactivity partly promotes the development of peripheral artery disease which mainly leads to ischemia of the lower limbs. Endovascular arterial denervation (ED) is a minimally invasive technique which could deliver Radiofrequency energy by a multi-electrode catheter to the Lower limb artery to restore Sympathetic activity. The purpose of this study is to evaluate the effects of multi-electrode radiofrequency ablation system on lower limb ischemia with PAD.

Peripheral arterial disease is a common, undertreated and under-researched issue. The vast majority of these patients often have multiple issues which can be improved with targeted behavioural change interventions. NICE has recommended that supervised exercise is the main stay of treatment for intermittent claudication (ischaemic muscle pain on walking due to blocked and narrowed arteries). However, in the vast majority of UK hospitals this isn't undertaken and with the issues around group-based sessions and repeated visits to hospitals this treatment option is not available with the coronavirus pandemic. We proposed a single centre randomised control trial in 60 patients with peripheral arterial disease attending the Freeman Hospital. Patients will be randomised to either an enhanced behavioural change intervention targeting multiple health behaviours vs a simple walking intervention. We will also be embedding focus groups to understand patients experience of the intervention and whether the intervention is feasible and acceptable allowing changes to be made to the program. The primary outcome will be to assess the feasibility and acceptability of the program. We will also be assessing multiple secondary outcomes including functional capacity, quality of life, sleep quality and smoking and alcohol reduction.

This INITIATE study evaluates the use of high-intensity interval training as a treatment modality for patients with intermittent claudication - an ambulatory leg pain caused by narrowed arteries that supply the lower limbs. It is an observational cohort study considering HIIT as a treatment for intermittent claudication, consisting of two workstreams. Workstream 1: an initial observational cohort study to consider the feasibility of the intervention and exclusion criteria. Workstream 2: a proof of concept study utilising the altered intervention and exclusion criteria following recommendations highlighted during workstream 1.
