Filter by:TA prospective randomized control trial to evaluate the serration angioplasty effect in BTK arteries with varying degrees of calcified plaque.
Whilst mortality rates and surgical limitations are widely known and understood for each intervention performed, the cost implications, in UHL, are not known. Therefore, it is deemed a matter of interest to understand these costs and weigh them against the mortality rates for each intervention if available.
The purpose of this study is to determine if allogeneic Endothelial Progenitor Cells (EPCs) intravenous infusion to a subject with leg ulcer and/or gangrene due to poor blood flow will be safe and if it will relieve leg pain, increase blood flow, and/or cure the leg wound.
Peripheral artery disease (PAD), vascular disease of atheromatous origin, is a frequent pathology, with a steady and significant increase in prevalence over the last decades. It has various symptoms ranging from mild arterial claudication to critical limb ischemia. The critical ischaemia stage in PAD is defined by rest pain or trophic disorders and is a special situation because of the number of cardiovascular deaths at 1 year (25%), 60% at 5 years and acute ischaemic recurrence at 1 year (25%). It is a medico-surgical pathology. A haemodynamic marker is needed to monitor patients, as it is predictive of limb progression, cardiovascular events and mortality. The Systolic Rise Time (SRT) of the plantar footpad is a recently described haemodynamic measurement of proven value in the diagnosis of PAD. The aim of this study is to show the prognostic value of the Systolic Rise Time on Major Adverse Limb Events (MALE).
Critical Limb Ischaemia (CLI), the final stage of arterial disease, is a therapeutic emergency whose prognosis depends largely on the time taken to diagnose it. The growing prevalence of this condition and the associated healthcare costs make it an important public health objective. Diagnostic criteria for Critical Limb Ischaemia differ between learned societies and countries. Its diagnosis is most frequently based on the combination of a clinical criterion (ischaemic decubitus pain and/or necrotic wounds, with a time to onset > 2 weeks) and a haemodynamic criterion (ankle systolic pressure (ASP) < 50mmHg or toe systolic pressure (TSP) < 30 mmHg or transcutaneous oxygen pressure (TCPO2) < 30 mmHg). Recent studies have highlighted the importance of pulsed Doppler flow analysis in quantifying arteriopathy of the lower limbs, both by systematically analysing flow modulation and by measuring the systolic rise time of distal arteries (dorsal artery of the foot and lateral plantar artery). The main aim of our study is therefore to validate a reliable and accessible diagnostic tool for screening patients suffering from CLI so that they can be referred to a reference centre as early as possible.
The goal of this Phase 0 clinical trial is to evaluate safety and biodistribution of [89Zr]Zr-DFO-APAC in patients with peripheral arterial occlusive disease / critical limb ischemia (PAOD/CLI) and healthy volunteers. The main questions it aims to answer are: - What is the safety, tolerability and pharmacokinetic profile (PK: both systemic and local vascular injury site-specific PK) of [89Zr]Zr-DFO-APAC? - What is the biodistribution and internal radiation dosimetry of the tracer dose of [89Zr]Zr-DFO-APAC? - What is the binding and retention time of [89Zr]Zr-DFO-APAC to arteries and atherosclerotic or microvascular lesions? Participants will receive a dose of the [89Zr]Zr-DFO-APAC (IMP) and PET/CT imaging is performed on days 1, 3 and 7, and follow-up visit 7-14 days post IMP dosing.
We wish to conduct two vascular ultrasound scans conducting vein measurements in two separate scanning rooms to assess if environmental temperature affects the vein diameter recorded.
Peripheral arterial disease (PAD) is a disabling condition, with symptoms of muscle cramping or pain on exertion, which can substantially reduce quality of life. This study aims to see if AirGlove device improves participants circulation. This is phase 1 study and will be taken in 3 parts: Phase 1a will be undertaken in 10 healthy volunteers to assess the effects of the AirGlove device on lower limb arterial flow, tissue perfusion, quality of life and product usability following a single session. Phase 1b will be undertaken in 20 participants with intermittent claudication to assess the effects of the AirGlove device on lower limb arterial flow, tissue perfusion, quality of life and product usability both in a single session and following a 12-week trial of heat therapy. Phase 1c will be undertaken in 10 participants with critical limb ischaemia Rutherford stage 4 (rest pain). Lower limb arterial flow, tissue perfusion, pain scores, quality of life, and product usability will be assessed both in a single session and following a 2-12 week trial of heat therapy.
This clinical trial included 2 periods. During the first period, it was a single arm study to explore the safety of umbilical cord artery-derived stem cells (UCA-PSCs) in the treatment of patients with critical limb ischemia (CLI). During the second perid, it was a single-center, randomized, controlled prospective study to determine the efficacy of the UCA-PSCs treatment. Those who had CLI were enrolled in the study.
The purpose of this trial is to evaluate the safety and efficacy of the Drug Eluting Temporary Spur Stent System compared to PTA. The Drug Eluting Temporary Spur Stent System is intended for use as a primary treatment in the infrapopliteal arteries for the treatment of de novo or restenotic lesions.
