Filter by:The purpose of this study is to answer the following question: Leads a primary coagulation corrected with a single dose of fibrinogen concentrate after ascending aorta-arc reconstruction to a decrease in the number of allogenic blood transfusions, compared to placebo?
The purpose of this study is to assess the clinical outcomes and radiation of the use of off-the-shelf and custom-made devices (CMDs) for the endovascular repair of juxtarenal, suprarenal, thoracoabdominal and arch aortic aneurysms in patients having appropriate anatomy. The study consists of three cohorts. The first 2 cohorts are the continuation of the current IDE study. The first cohort is aimed to assess the use of custom-made devices (CMDs) for the endovascular repair of juxtarenal, suprarenal and type IV thoracoabdominal aortic aneurysms in standard and high-risk patients having appropriate anatomy (Fenestrated-CMD cohort). The second cohort (Type I-III thoracoabdominal cohort) includes standard and high-risk patients with type I- III thoracoabdominal aneurysms that require the use of branched/fenestrated CMDs, or, in selected cases, the Zenith Thoracoabdominal Branch (Zenith® t-Branchâ„¢) device. Finally, the third cohort (the Arch cohort) will include 25 high-risk patients with aortic arch aneurysms treated by patient-specific stent-grafts with one to three inner branches or a scallop
The aorta is a large vessel that carries blood away from the heart. Sometimes it becomes dilated (swells) and this is known as 'aneurysm'. It may cause either dissection (splitting of the wall) or rupture (bursting). Treatments could be through open surgery or by use of stents (tubular mesh) through the groin. There is a risk of causing paraplegia, which is the loss/weakness of leg function as well as incontinence (loss of bladder and/or bowel control). To try and prevent this, a number of techniques are used such as removing/draining of cerebrospinal fluid (CSF) (the clear fluid surrounding the brain and spinal cord). Sometimes however; - CSF cannot be drained - drain cannot be inserted - draining is unlikely to improve the situation - Paralysis/weakness of the leg is seen In these situations, the use of a drug called acetazolamide may be helpful. This reduces the production of CSF and therefore decreases the need for CSF draining. It may also have an effect in decreasing the risk of paraplegia. Patients will be randomly (by chance) placed into one of two groups. One will get the drug as tablets and injection and the other will not receive any acetazolamide at all. Blood tests will be done in both groups. We expect to have 100 patients in the study, with patient involvement for a total of 10 days (maximum).
