Active clinical trials for "Ischemia"

This study seeks to investigate the capillary index score (CIS) to further improve patient selection of endovascular treatment (EVT) in acute ischemic stroke (AIS). The hypothesis or idea being tested: Patients with favorable CIS who are successfully revascularized with EVT can have successful outcomes with an extended time window for treatment.

This study evaluated epidemiology and clinical outcome of clopidogrel related various genotyping in Korean patients who had undergone percutaneous coronary intervention as a all comer registry form.

Patients diagnosed with NAION within 14 days of onset were included. Patients were randomized into 3 groups. Group 1 or control consisted of 30 patients who received gelatinous capsules filled with sugar as placebo. Group 2 or steroid consisted of 30 patients received methylprednisolone (Solu-Medrol, Pharmacia Pharmaceutical Company, Belgium) 500 mg twice a day for 3 days followed by 2 weeks of oral prednisolone 1mg/kg/day. Thirty patients in group 3 or oxygen received 100% normobaric oxygen with face mask in sitting position, at a flow rate of 5 liters per minute for 1 hour twice a day for two weeks Functional and structural outcomes were assessed at 1 and 6 months following treatment. Best corrected visual acuity was the main outcome measure, and mean deviation index of visual field test and peripapillary retinal nerve fiber layer thickness were secondary outcome measures.

International Multi-Centre registry recording comprehensive data on the use of 'Indigo' Mechanical thrombectomy system by Penumbra Inc for the removal of acute clot causing acute or critical limb ischaemia.

Use of endovascular techniques - implantation of a peripheral stent graft and a peripheral flexible stent to isolate the sac of the popliteal artery aneurysm from the circulation and subsequent topical application of a thrombolytic (rtPA) to restore patency of the lower leg blood stream - will lead to a comparable or better outcome in treatment of patients with the popliteal artery aneurysm and acute critical limb ischaemia, compared to currently prevailing use of surgical treatment.

Laugh is more than visual and vocal behave, is always followed by a series of physiological changes, including contractions of musculoskeletal system, increase of cardiac frequency by catecholamine release and hyperventilation that promoves the increase of maximum breathing and oxygen saturation. Laugh therapy may be an alternative therapy, simple, and improve the quality of life of individuals can influence physiological and biochemical parameters of the human body.

The benefit of mechanical thrombectomy in the treatment of ischemic stroke has been demonstrated in several multicenter randomized trials. However, it leads to a sudden reperfusion of the brain parenchyma associated to an extension of the infarct volume. Evidence has indicated that remote ischemic conditioning (RIC) reduces final infarct size in animal stroke models. The main objective of the present study is to determine whether remote ischemic conditioning can limit the final infarct volume after recanalization of the occluded cerebral artery.

Using random number method to categorize the selected first onset patients with stroke who meet the inclusion criteria into 3 groups.The patients were randomly divided into treatment group A(abdominal acupuncture+upper limb rehabilitation training, 22 cases), treatment group B(Sham abdominal acupuncture+upper limb rehabilitation training, 22 cases),and control group(upper limb rehabilitation training, 22 cases). SEMG and fMRI examination and related stroke rehabilitation assessment scales were evaluated before and after treatment.

Personalized therapy as prophylaxis in ischemic stroke patients is not yet an option. From patients with ischemic heart disease, we know that patients with in vitro high on treatment platelet reactivity (HTPR) have an increased risk of stent thrombosis following per-cutaneous coronary intervention. Other studies have shown association of CYP2C19 genotypes with different responses to the anti platelet drug Clopidogrel. We measure HTPR in ischemic stroke patients on increasing doses of clopidogrel and investigate the CYP2C19 genotype for each patient.

Thoracic endovascular repair (TEVAR) and transcatheter aortic valve implantation (TAVI) are standard of care procedures to treat thoracic aortic aneurysm or severe aortic stenosis, respectively. Both procedures have a high risk of stroke and silent infarction. Gas has been detected in the cerebral vasculature during these procedures and associated with DWI positive lesions on MRI. The hypothesis is that air emboli contribute to stroke and silent infarction. The investigators propose addressing air emboli by flushing the device with carbon dioxide prior to flushing with saline. This is a pilot study comparing standard saline flush alone to carbon dioxide flushing with saline flush.
