Filter by:Purpose: Peripheral artery disease (PAD) is associated with elevated oxidative stress, and oxidative stress has been implicated as the cause of reduced endothelial reactivity in individuals with PAD. Endothelial function is important because the endothelium contributes to the dilation of arteries during exercise, thereby implicating impaired endothelial function as a mechanism contributing to exacerbated exercise-induced ischemia. Therefore, the purpose of this study is to test the hypothesis that acute exogenous diroximel fumarate (Vumerity) intake will improve antioxidant capacity, thereby reducing oxidative stress and improving vascular function and walking capacity in those with PAD. Eligibility: Individuals with PAD will be deemed eligible for this study if they 1) are 50-75 years old and postmenopausal, 2) have a positive history of exercise-limiting claudication (Fontaine II or III), 3) do not have renal impairments, 4) do not have Fontaine stage IV PAD, and 5) are not currently pregnant or nursing. Age-matched controls will be deemed eligible for this study if they 1) are 50-75 years old and postmenopausal, 2) have an ABI greater than 0.9 (no PAD), 3) do not have exercise-limiting diseases or injuries, 4) do not have renal impairments, and 5) are not currently pregnant or nursing. Intervention and Evaluation: During this study, participants will be administered diroximel fumarate or a placebo, and the acute effects of diroximel fumarate on vascular function and walking capacity will be assessed. Vascular function and walking capacity will be assessed with flow-mediated dilation, arterial stiffness, head-up tilt test, blood biomarkers, near-infrared spectroscopy, and a treadmill test. Follow-up: There will be a follow-up visit to assess blood work after diroximel fumarate.
This is a randomized controlled trial in which patients with moderate to severe shoulder pain (Visual Analog Scale (VAS) > 40), in the setting of rotator cuff tendinopathy refractory to conservative treatment, will be enrolled. The primary aim of the study is to estimate the effect of transcatheter arterial embolization (TAE) with physical therapy (PT) vs PT alone on the change in shoulder pain at 12-month follow up. Scientific objectives also include an assessment of safety of the intervention, assessment of changes in Patient-Reported Outcomes Measurement Information System (PROMIS) Upper Extremity score, Shoulder Pain and Disability Index (SPADI) scores, MRI Tendinopathy Score between the TAE + PT and PT groups.
Several studies have demonstrated that simultaneous treatment with two stentrievers (STs) as rescue treatment is very effective, with high recanalization rates even in this group of patients where other revascularization techniques have failed. There has been no observed increase in hemorrhagic complications. Recently, a prospective study has been published where treatment with two ST has been shown to be effective and safe if used as a first-choice treatment (not as rescue) with a successful recanalization rate (eTICI 2c/3) after the first pass of 69%. These results have been reinforced after the publication of a randomized study that confirms, in vitro, the superiority of using two ST over one.
The Easy Flype Carbostent™ is a CE-marked nitinol self-expanding stent for superficial femoral artery (SFA) and Easy HiFlype Carbostent™is a CE-marked nitinol self-expanding stent for iliac vessels. The aim of this post-market retrospective study protocl P42201 is to collect clinical data of patients treated with Easy Flype or Easy Hi Flype for the stenosis or occlusion of the iliac artery, femoral artery and first third of the popliteal artery in routine clinical practice. In order to obtain long-term follow-up data, the data collection will be limited to patients that have been treated with these devices at least 12 months prior to the study start.
Recent studies revealed the safety and effectiveness of EVT in patients with acute occlusion at basilar artery, showing that up to 46% of patients receiving EVT had favorable functional outcome at 3 months (ATTENTION and BAOCHE trials, ESOC). Although the rate of successful recanalization can be as high as 90% , a large number of these patients remains to be functionally independent while recovery. In addition, a number of recent studies indicated the functional outcome of patients with successful recanalization of TICI 2b was not as good as those with TICI 3 grade. Therefore, restoring reperfusion of distal vessels and territorial microcirculation may be pivotal to further improvement of neurological outcomes for AIS patients receiving EVT. Correspondingly, a very recent Spanish multicenter randomized trial showed the effect of further functional improvement of post-EVT intra-arterial alteplase for successful mechanical thrombectomy in anterior circulation More importantly, head-to-head comparison between TNK and tPA showed the former has a significantly higher chance of reperfusion, indicating that TNK may be a potentially better candidate for post-EVT bridging. Based on the above findings, we hypothesize in the present study that, adjunct intra-arterial tenecteplase after successful thrombectomy could enhance the functional improvement in patients with acute basilar artery occlusion.
Interwoven self-expandable stent is a recent endovascular method to treat complex femoropopliteal lesions trying to reach a reasonable patency and durability like in surgical bypass.
The spectrum of lower extremity peripheral arterial disease (PAD) ranges from exhibiting no symptoms to limb threatening gangrene. The number of patients living with it is rising steadily owing to increased life expectancy, obesity, diabetes, and tobacco consumption. Critical limb ischemia (CLI) is the terminal and the most serious stage of PAD in which blood flow to the lower extremity does not meet metabolic demands of the tissues at rest. The diagnosis is mainly clinical and patients are presented with rest pain, minimal tissue loss or frank gangrene. Revascularization strategies include endovascular procedures and surgical bypass.Endovascular therapy has evolved as an attractive, minimally invasive method of revascularization especially in the more frequently encountered patients with medical and anatomical contraindications to surgical revascularization. Antegrade approach is the standard approach in infrainguinal arterial occlusive disease,however, failure occurs in about 20% of infrainguinal attempts.Retrograde approach is used as a backup technique in failed cases.
Tissue perfusion assessment is key to more accurate measurement of foot ischemia, which is in turn an important factor in appropriate treatment decisions. In practice though, tissue perfusion measurements are not routinely undertaken as few practical solutions exist that are easy to use and fit in everyday clinical practice. Pedra has developed a novel easy to use, non-invasive device that can be used in practice to better inform treatment decisions.
The objective of this study is to determine the rate of early radial artery occlusion following 7-French(7-Fr) transradial coronary intervention using a new Terumo (Tokyo, Japan) Glidesheath Slender, in comparison with the currently used 7-Fr radial sheath.
