Active clinical trials for "Vascular System Injuries"

Stents are used at centers around the world to unblock the arteries of the heart. These stents are usually made of metal and remain permanently within the blood vessel wall. Newer developments in the stent technology has led to stent scaffolds that can be reabsorbed over time. Patients with diabetes are prone to more complex blockages in the heart arteries which can be more difficult to treat. The purpose of this study is to compare the difference of how arteries heal early when metal stents or resorbable stents are used in patients with diabetes.

Stroke can lead to signficiant neurological deficits, and about one-third of stroke patients will be diagnosed of vascular mild cognitive impairment or post-stroke dementia. Post-stroke dementia includes all types of dementia that happen after stroke, irrespective of their cause, and vascular dementia (VaD), degenerative dementia (especially Alzheimer's disease), or mixed dementia (dementia as a result of the coexistence of vascular lesions of the brain and neurodegenerative lesions) are the most common causes of post-stroke dementia. However, it is difficult to determine to what extent cognitive impairment may be attributable to stroke versus concomitant Alzheimer disease. With the advent of PET imaging technique, we are able to conduct a multi-modal neuroimaging study to explore the composite influence of vascular injury, amyloid plaque and Tau protein the the cognitive performance after stroke.

We plan to track the migratory behaviour of culture-expanded enothelial outgrowth cells in the context of vascular injury sustained during elective coronary angiography. We will use Flouro-deoxyglucose-labelling and PET-CT to track the endothelial cells.

Ischeic reperfusion injury lead to a cellular dyfunction and increase in soluble glycocalyx of blood flow. syndecan-1 was a marker of glycocalyx. The purpose of this study is to prove the variation of level of serum syndecan-1 between preoperative and postoperative period.

To investigate the biosynthesis of PGD2 during percutaneous transluminal coronary angioplasty (PTCA) procedure.

The aim of this study is to investigate the relation between the previous presence of endothelial dysfunction and the development of radial artery vasospasm during the trans-radial coronary evaluation.

Data will be collected on the type of tourniquet and circumstances of its use. Patients with penetrating extremity injury will have clinical and pre-clinical hospital data collected.

A large proportion of Asian patients with HCC present with locally advanced or metastatic disease,at which point they are ineligible for curative treatments.Oxaliplatin plus fluorouracil/leucovorin intravenous infusion was proved effective in prolonging progression-free survival(PFS) than doxorubicin as palliative chemotherapy in patients with advanced HCC from Asia. Besides, hepatic arterial infusion chemotherapy (HAIC）is a widely used method for primary or metastasis liver tumor with high local tumor response. To our knowledge, there have not been any prospective studies to assess the safety and effecacy of HAIC using oxaliplatin plus fluorouracil/leucovorin for patients with locally advanced HCC.Thus,the purpose of this phase 2 study was to assess the safety and effecacy of HAIC using oxaliplatin plus fluorouracil/leucovorin for patients with locally advanced HCC.

This project aimed to explore novel methods of detecting small blood vessel disease in a paediatric population with type 1 diabetes mellitus. To do this the techniques of Nailfold capillaroscopy, laser Doppler flowmetry, retinal (eye) vessel analysis and 24-hr Ambulatory Blood Pressure Monitoring were used. Each of these techniques investigated different areas of small blood vessels around the body. It was hypothesized that in a paediatric population with type 1 diabetes mellitus the novel investigations would be associated with small blood vessel disease and that widespread changes to these blood vessels would be detected through associations between the different novel investigations.

Individual patient expanded access requests may be considered for patients who have no other treatment options and are not eligible for an HAV clinical study
