Effect of Propofol Midazolam on Cerebral Oxygenation and Metabolism During Clipping of Ruptured...

Ruptured Cerebral Aneurysm

Despite the theoretical benefits of i.v. agents, volatile agents remain popular. In a study comparing desflurane, isoflurane, and sevoflurane in a porcine model of intracranial hypertension, at equipotent doses and normocapnia, cerebral blood flow (CBF) and ICP were least with sevoflurane. Propofol is the most commonly used intravenous anesthetic. It has many theoretical advantages by reducing cerebral blood volume (CBV) and ICP and preserving both autoregulation and vascular reactivity. Neurosurgical patients anaesthetized with propofol were found to have lower ICP and higher CPP than those anaesthetized with isoflurane or sevoflurane. The well known pharmacodynamic advantages of intravenous anesthetics may give this group of drugs superior cerebral effects when compared with inhalation anesthetics.

The Inter and Intra Reliability of Cardiopulmonary Exercise Testing in Abdominal Aortic Aneurysm...

Abdominal Aortic Aneurysm

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.

ANEUFIX for Endoleaks Type II

Abdominal Aortic Aneurysm

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.

The Transfusion Triggers in Vascular Surgery Trial

AtherosclerosisAnemia3 more

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.

Surgical Theater's Surgery Rehearsal Platform

Cerebral Aneurysm UnrupturedCerebral Aneurysm Ruptured

Objectives: The objective of this clinical study is to determine if the use of the SRP will lead to improved effort and time efficiency in cerebral aneurysm surgery. For this preliminary study, the investigators will assess key time and effort variables associated with prospectively assessed SRP neurosurgery cases in comparison with cases with no SRP rehearsal. This is a single site study with one enrolling site. This study will include a total of 40 cases 20 SRP cases and 20 control cases). SRP and control cases will be randomly selected according to a predetermined alternating sequence.

Statin Use in Abdominal Aortic Aneurysm Repair

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.

Comparison of Abdominal Aortic Aneurysm Growth in Adult Smoking Patients Who Either Switch to IQOS,...

SmokingAbdominal Aortic Aneurysm1 more

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.

Prevalence and Factors Associated With the Occurrence of Depression Six Months After an Endovascular...

Intracranial Aneurysm

During the last decade, the embolization has become the treatment of choice for ruptured intracranial aneurysms, to improve the neurological outcome of patients. At the same time, for his safety, she also became the technique allowing prophylactic treatment of unruptured intracranial aneurysms discovered incidentally during imaging exams. Regarding patients with ruptured intracranial aneurysms, patients who survive often have a reduced quality of life while one in two has a good neurological outcome after embolization. Depression, anxiety and fatigue, whose the psycho-social impact is important, are often cited. This description has often been done without considering the realized type of treatment (surgery or embolization) and mostly of neurological and functional status of the patient remotely (disability or not in daily activities). Regarding patients with unruptured intracranial aneurysms, they are mostly asymptomatic and embolization is programmed. They would present an cognitive impairment in one case in five at 1 month of treatment. If depression, fatigue and difficult return to working life are logically found in patients with severe sequelae (disability in daily activities) of their ruptured intracranial aneurysms, the question arises for patients with a ruptured intracranial aneurysms with a favorable evolution and for asymptomatic patients with unruptured intracranial aneurysms. A precise status of these populations is necessary, especially as the discovery and treatment of their intracranial aneurysms is often early (between 40 and 60 years) and that their good neurological status should allow "a priori" to return easily at the active life.

Modern Technology For Learning and Psychosocial Support In Patients With Abdominal Aortic Aneurysm...

Aortic Aneurysm

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.
