Active clinical trials for "Aortic Aneurysm"

The role of teleradiology has far reaching implications for the health of remote and underserved populations. The ability to coordinate radiographic evaluation and diagnosis from a distance has the potential to raise the standard of patient care throughout the world. Perhaps the safest and most cost effective mode of teleradiology today is telesonography. The current project attempts to determine the extent that telesonography improves the standard of care within a rural government-run primary clinic within the Dominican Republic. The work reported herein is intended to compare the use of telesonography to the current standard of sonographic examination (referral to government hospital 60km from target clinic). The study was conducted by randomly assigning 100 patients with clinical indications for sonographic examination into experimental and control groups. Following a 60-day implementation period, the following research questions will be addressed: 1) To what extent does the use of asynchronous telesonography increase the percentage of definitive diagnoses based on the total number of scans (definitive diagnoses / total number of scans)? 2) To what extent does the use of asynchronous telesonography increase the continuity of care for patients? 3) To what extent does the elapsed time between scanning and final radiological interpretation decrease with the use of asynchronous telesonography? This study will also look at the history of telemedicine / telesonography and its dissemination into the mainstream practice of medicine, explore training protocols that may be used to assist others to establish new telesonography programs in a developing nations, and discuss both advances and persistent barriers to the implementation of telesonography programs. Hypothesis: The use of a store-and-forward telesonography system in this setting will increase the speed and number of final diagnoses per scan received by the target clinic and will increase the continuity of care by increasing the number and speed of follow-up appointments to the target clinic.

Exercise testing is commonly being used in patients before surgery to test their overall fitness. One group it is being used in is patients who have an enlarged blood vessel in their stomach. This is known as an abdominal aortic aneurysm. The exercise test used is known as a cardiopulmonary exercise test as it looks at both heart and lung function at the same time. Whilst this test is commonly used there have been no studies (to date) which have looked at how reliable this test is; this means how well the investigators can obtain the same (or very similar) results after multiple tests. The investigators would like to test this reliability both between patients and the clinicians performing the testing.

The study is a non-randomized, multi-center safety and feasibility trial of Aneufix ACP-T5 to treat patients with Isolated type II endoleak in the presence of a non-shrinking AAA sac following an EVAR procedure.

BACKGROUND Vascular surgical patients often receive red blood cell (RBC) transfusions in the peri-operative period RBC transfusion may lead to improved outcome but on the other hand the intervention may be harmful Danish Health and Medicines Authority recommends transfusion of RBC at hemoglobin below 5 mmol/L while local clinical guidelines recommend transfusion of RBC to maintain hemoglobin levels above 6 mmol/L A large randomized clinical trial is needed to evaluate the efficacy and safety of RBC transfusion in patients undergoing vascular surgery. A trial examining the effect of RBC transfusion on tissue oxygenation is used to test the trial-design and feasibility for a trial evaluating post-operative mortality and morbidity.

This is an investigation of the efficacy and safety of CRD007 compared to placebo in the treatment of patients with abdominal aortic aneurysm.

Aneurysm formation is associated with a chronic inflammatory response, depletion of smooth muscle cell population and excessive matrix metalloproteinases (MMPs) production. 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase inhibitors (statins) are lipid lowering agents with pleiotropic effects including anti-inflammatory activity. Elective open AAA repair patients will be randomised to receive either statin (Atorvastatin 80 mg) or placebo (dummy tablet) for 4 weeks pre-operatively. Tissue samples will be obtained from patient's aneurysm to assess MMP's and their inhibitors TIMP's. It is hypothesized that patients receiving statin will have reduced MMP's.

The purpose of this study is to evaluate the reduction of the Abdominal Aortic Aneurysm (AAA) annual growth rate in patients who switch from smoking cigarettes to using IQOS as compared to patients who continue to smoke cigarettes. The study also aims to provide context to the scale of reduction in the growth rate, by comparing the AAA annual growth rates for continuing to smoke and switching to IQOS with the AAA annual growth rate in smokers who had stopped smoking. The study will further evaluate the effects of switching to IQOS on co-morbidities observed in AAA patients that are related to smoking as well as to assess the effects on relevant clinical risk endpoints linked to smoking related diseases.

This study evaluates the effects of an eHealth tool and psychosocial support on anxiety, depression and health-related quality of life in patients undergoing surgical treatment for abdominal aortic aneurysm (AAA). Participants in the intervention group will receive access to the eHealth tool and structured follow-up with a contact nurse, the control group will receive standard of care.

The matrix metalloproteinase-9 (MMP-9) is considered to play a central role in abdominal aortic aneurysm (AAA) initiation. Doxycycline has direct MMP-9 inhibiting properties in vitro, and it effectively suppresses AAA development in rodents. Observed inhibition of AAA progression, and contradictory findings in human studies evaluating the effect of doxycycline therapy on aortic wall MMP-9 suggest that the effects of doxycycline extend beyond MMP-9 inhibition, and that the effect may be dose dependent.

The purpose of the study is to determine the plasma levels of CRD007 in patients with abdominal aortic aneurysms after the administration of single doses of tablets containing 10, 25 and 40 mg CRD007.
