Peripheral Arterial Disease(PAD)

The goal of this observational study or clinical trial is to investigate how exercise can affect different areas of a person's life, especially those people with vascular disease. This is important because exercise can be beneficial for people with vascular disease. The study could include any of the following: those aged 65 years of age and older, between the ages of 50-64 who smokes, has diabetes, high blood pressure, high cholesterol, or has a family member with vascular disease, between the ages of 18-49 with diabetes and one other factor listed above, or those with vascular disease. The main question\[s\] it aims to answer is if exercise testing can better predict vascular disease. The following research questions will be addressed in this study: 1. Does baseline ABI influence the magnitude and recovery trajectory of ABI following an acute bout of exercise across a spectrum of vascular function? 2. What association does exercise-induced ABI changes have on patient-reported outcomes of quality of life and intermittent claudication? 3. Do functional outcomes of gait speed, time to claudication, gait variables related to rest breaks in 6MWT, and walking distance predict the magnitude of exercise-induced ABI reduction? Participants will : * complete various questionnaires and a routine screening for vascular disease \*walk for 6 minutes at your own pace * additional vascular screening tests will be performed.

The purpose of this study is to determine if IVUS use, as compared to angiography alone, prevent major adverse limb events (MALE) or binary restenosis (a greater than 50% re-narrowing of the treated artery) in adult patients who have CLTI and are undergoing percutaneous revascularization.

This study aims to assess a simple intervention: Visualization of lymphatic injury + treatment (in case of detection). This will generate data on the incidence of intraoperative lymphatic injury and the effect of treatment. This data will then hopefully enable a multi-center RCT to generate high level evidence on this matter.

The study is observational and involves patients (pts) with peripheral arterial occlusive disease (PAD) who have undergone lower limb revascularization procedures. Patients who are at least one year post-procedure will be contacted by phone and asked whether any cardiovascular complications occurred during that period, specifically major adverse cardiovascular events (MACE) or major adverse limb events (MALE), and whether they had been taking sodium-glucose co-transporter 2 inhibitors (SGLT2-i, "flozins") during the year following the procedure. The results from the group of pts who, for any reason, received SGLT2-i treatment after the vascular procedure (including those who had initiated treatment before surgery) will be compared to the results from the group of patients who did not receive such treatment, with regard to the occurrence of the aforementioned complications.

The XTRACT Registry is a prospective, single arm multicenter study on the use of on the Rotarex(TM) Rotational Excisional Atherectomy System.

To explore the usefulness of SFDI in the assessment of revascularization pre and post intervention

The purpose of the study is to examine whether incision type has an influence on the development of groin wound complications after operation in the groin in vascular surgery. The main questions it aims to answer are: Does a transverse incision in the groin lead to fewer surgical site complications than a longitudinal incision? Does a transverse incision lead to fewer readmissions, fewer reoperations, shorter length of hospital stay, and a lower amputation rate. Participants will undergo vascular surgery in the groin with either a transverse or longitudinal incision. The incision type will be selected randomly.

1. Study design: multicenter retrospective and prospective observational study 2. Study Cohort : 1. Retrospective cohort: This cohort retrospectively enrolls patients with lower extremity artery disease who underwent endovascular treatment from January 2006 to the date of approval by IRB in the participating hospitals. Informed consent was waived by IRB. 2. Prospective cohort: This cohort prospectively enrolls patients with lower extremity artery disease who undergo endovascular treatment from the date of approval by IRB to July, 2018 in the participating hospitals. Informed consent will be obtained prior to enrollment. 3. Baseline clinical and lesion characteristics, procedural and post-procedural data, clinical outcomes, hemodynamic, and imaging follow-up data are investigated. Primary patency and target lesion revascularization rates of the total cohort and patient subgroups are evaluated. Risk factors of restenosis and target lesion revascularization are determined.

This study is a multicenter, prospective, observational research project. It is anticipated to enroll a total of 6,000 patients between February 1, 2025, and January 31, 2028 (with completion of one-year postoperative follow-up by January 31, 2029). Patients will be grouped according to different combinations of anticoagulant and antiplatelet drugs used postoperatively for PAD. The types, dosages, and duration of postoperative anticoagulant and antiplatelet drug use will be recorded. Follow-up assessments will be conducted at 1 month, 6 months, and 12 months postoperatively to document the occurrence of Major Adverse Cardiovascular Events (MACE) and Major Adverse Limb Events (MALE) in the enrolled patients.

The purpose of this study is to evaluate the standard of care practices, procedural outcomes, and in-hospital complications for endovascular peripheral interventions of femoral, popliteal and infrapopliteal lesions.

The aim of this study is to investigate the effects of virtual reality exercises on lower extremity skin temperature, arterial stiffness, gait parameters and enjoyment of exercise in individuals with peripheral arterial disease.
