Filter by:Our laboratory has discovered that ultrasound (US) imaging together with clinically approved microbubble ultrasound contrast agents can augment limb tissue perfusion. These observations have been made in mice with and without peripheral artery disease (PAD), and also in humans where high power contrast enhanced ultrasound (CEU) was used to measure perfusion but was found also to augment perfusion by almost 2-fold. The latter human studies were performed with ultrasound protocols designed for perfusion imaging and not for flow augmentation. In this study, we will measure the degree to which limb perfusion is augmented with specific therapeutic CEU settings that are still within the FDA-approved limits with regards to US power and contrast dosing.
This study is designed to determine whether LLG783 displays the clinical safety and efficacy profile, after multiple i.v. doses, to support further development in patients with PAD and intermittent claudication.
The objective of this study is to assess the clinical use of the Bard® UltraScore™ Focused Force PTA balloon in a heterogeneous patient population in a real world, on-label clinical application.
A prospective, non-randomized, international, multi-center study to evaluate the safety and effectiveness of the Pantheris OCT-Imaging System to perform atherectomy in In-Stent Restenotic (ISR) lesions in lower extremity arteries.
Over the past years, arterial closure systems have tended to replace manual compression to ensure hemostasis at femoral artery puncture points. Arterial closure systems reduce hemostasis and patient immobilization times, thus enabling early resumption of walking. These devices have contributed extensively to the development of outpatient stays for cardiology, vascular and neuro-radiology procedures. However, main arterial closure devices use different technology to close the arterial puncture point. For some, hemostasis is achieved by sealing the arteriotomy between two discs (an inner and an outer). For others, they are designed to close puncture sites delivering a single monofilament polypropylene suture mediated by needles. The investigators hypothesis is based on a different efficacy between both arterial closure devices for peripheral arterial disease (PAD) patients.
This is a prospective, multicenter, single-arm clinical trial to evaluate safety and efficacy of a steerable catheter in the establishment of vascular intervention access. five centers participate in this study. The total enrollment number is 68. In the procedure of vascular interventional surgery or angiography diagnosis, the steerable catheter are used to building vascular interventional access. Evaluate the safety and efficacy of the product, by the observation and record the relative index of subjects intraoperative and postoperative (discharge) before and after 30 days .
The overall goal of SHOWME-PAD is to make the existing evidence-base on treatment outcomes -focusing on health status outcomes that reflect the patients' perspective - more transparently available to patients and providers, such that more informed, evidence-based shared treatment decisions occur. INTEGRITY-PAD has the potential to radically reorganize care delivery to patients with PAD such that more value for the patient and society will be created.
The vascular surgery is a highest risk procedure when considering postoperative complications associated with the cardiovascular system. The leading clinical presentation is acute hemodynamic decompensation. However, one of the possible pathomechanisms might be repolarization disturbances. Many of perioperative risk factors of cardiac complications are modifiable. The identification may help in the global perioperative risk reduction. Aim: The aim of the study was an identification of the factors which may release clinically overt repolarization disturbances. Methods: The study group consisted of 100 patients, diagnosed with abdominal subrenal aortic aneurysms or peripheral arterial disease scheduled for an elective "open" vascular surgery procedure. The authors investigated whether age, gender, comorbidities or some perioperative factors (including hemodynamic, metabolic or genetic) were related to the occurrence of clinically concealed repolarization disturbances or clinically disclosed cardiac complications in postoperative time up to 30 day and one year after vascular surgery procedure.
The aim of this study was to evaluate exercise testing in case of patients suspected of Peripheral Artery Disease (PAD).
Over the past years, arterial closure systems have tended to replace manual compression to ensure hemostasis at femoral artery puncture points. Arterial closure systems reduce hemostasis and patient immobilization times, thus enabling early resumption of walking. These devices have contributed extensively to the development of outpatient stays for cardiology, vascular and neuro-radiology procedures. According to certain studies however, it would appear that arterial closure devices do not present any greater benefits than manual compression in terms of hemostasis and complications. Moreover, the use of increasingly small diameter instruments would tend to render manual compression sufficient. Finally, the use of these devices generates additional costs. The purpose of our prospective study is to evaluate the feasibility and safety of same-day discharge after manual compression in patients treated for peripheral artery disease by endovascular technique with 5F sheath.
