Comparison of Aorto-iliac Endovascular Interventions With and Without the EndoNaut Workstation

Aortic AneurysmIliac Aneurysm3 more

The aim of this retrospective, multicenter study is to demonstrate that the use of EndoNaut for aortoiliac endovascular procedures has a clinical impact for the patient (reduction in irradiation and the volume of contrast product) as well as for the nursing staff (reduction irradiation) compared to procedures performed without EndoNaut.

Circulating Endothelial Progenitor Cells and Aortic Aneurysm

- Aortic Aneurysm

We aimed to see if aortic aneurysms could be followed-up by circulating endothelial progenitor cells CD34+144+CD14- and CD34+VEGF-R2+CD14- blood level.

The Effect of Abdominal Aortic Aneurysm Screening on Mortality in Asian Population

Aortic AneurysmAbdominal

Abdominal aortic aneurysm(AAA) occurs when the infrarenal aorta expands to a maximal diameter of 3.0cm or greater. Although AAA may asymptomatic for many years, almost one third eventually rupture if left untreated. Several randomized trials showed that ultrasonographic screening for AAA could reduce the frequency of acute operations and AAA-related mortality. However, all of randomized trials were performed in Western countries. There was no randomized trials for AAA screening in Asian countries. This randomized, controlled trial is to analyze the benefits of screening old population for AAA in Korea.

Contrast-enhanced Magnetic Resonance Angiography Investigation of Intracranial Aneurysms and Prospective...

Intracranial Aneurysm

This is a prospective observational registry with intent to detect the prevalence of intracranial aneurysms with contrast-enhanced MR angiography (CE-MRA) at 1.5T, and to determine the risk factors such as high blood pressure and cigarette smoking relating to intracranial aneurysms.

Pro-inflammatory Cytokines in Blood From Orthopedic Surgery Compared to Abdominal Aneurysm Repair...

Aortic DiseasesOsteoarthritis1 more

The purpose of this study is to investigate the contents in blood sampled from surgery site during hip replacement compared with blood sampled from abdominal aortic surgery. Is there any difference in pro-inflammatory cytokines (IL-1beta, IL-6, IL-8 and TNF-α), complement activation (C3a)?

Young Patient With Aortic Dissection or Aneurysm: A Prospective Observational Cohort Study

Aortic Aneurysm and Dissection

Aortic dissection or aneurysm is unusual in young patients, and frequently associated with unusual presentations. However studies about this area is scarce. Besides, the treatment option is not clare. The prognosis of this cohort is also unclear. The goal of this study was to better understand the characters, treatment option and prognosis of young patient with aortic dissection or aneurysm.

Fluid REsponsiveness and Arterial ELASTANCE in Patients With Septic Shock or After Aortic Surgery...

ShockSeptic7 more

The MostCare system, thanks to the Pressure Recording Analytical Method (PRAM; Vygon, Padua, Italy), provides new hemodynamic parameters of the cardiovascular system. The PRAM method is a noncalibrated pulse contour method which requires only an arterial line (radial or femoral). This method has been validated in various clinical conditions. Among the collected parameters, some are well known and used daily care in Intensive Care Unit (ICU), i.e. cardiac output (CO), arterial pressure, heart rate, stroke volume (SV). Others such as arterial elastance (Ea) or dicrotic pressure are more recent and merit further investigation to determine their interest in clinical practice. To date, it is rarely used to adapt therapies, mostly because of a lack of knowledge regarding the evolution of these parameters. The aim of this study is to analyze the relationship between the evolution of Arterial Elastance and fluid responsiveness after a 250 mL fluid challenge of crystalloids in 5 minutes in patients with either septic shock or in the postoperative course of a major vascular surgery. Patients will be considered fluid responders if an increase >10% of the stroke volume is observed .

Intraoperative Assessment of Pulsatile Aneurysm Wall Motion During Endovascular Aneurysm Repair...

Abdominal Aortic AneurysmEndovascular Abdominal Aortic Aneurysm Repair1 more

Endovascular abdominal aortic aneurysm repair (EVAR) aims to reduce the risk of aneurysm (AAA) rupture by reducing the blood pressure transmitted to the wall of the aneurysm. Aneurysms that remain pressurized despite EVAR may continue to grow, therefore requiring additional surgical interventions. The purpose of this study is to infer the reduction of pressure transmitted to the aneurysm wall by using intraoperative ultrasound ('M-Mode') to assess the pulsatility of the aneurysm wall. The hypothesis is that intraoperative reduction in aneurysm wall pulsatility after EVAR will correlate with improved aneurysm sac size reduction.

Organ Failure After Advanced Endovascular Thoracoabdominal Aortic Surgery

Aortic AneurysmSpinal Ischaemia1 more

The purpose of this study is to investigate the mortality and frequency of organ dysfunction in patients after endovascular thoracoabdominal aortic surgery, and to search for biomarkers of organ dysfunction, in particular the spinal cord, the kidneys and the gastrointestinal tract. All adult patients undergoing endovascular thoracoabdominal aortic surgery at Örebro University Hospital, Örebro, Sweden, are asked for participation in this study. All participating patients sign informed consent at the inclusion. During the operation and during the postoperative intensive care, the function of the spinal cord, the gastrointestinal tract and the kidneys are collected along with other clinical parameters. Plasma blood samples, urin samples and cerebrospinal fluid samples are collected from each patient during the operation and during the postoperative care at the intensive care unit. During the operation two microdialysis catheters are placed in the abdomen, and the samples are continuously collected and analyzed. The biomaterial samples are stored in a biobank for later determination of proteins and other molecules. Postoperative survival and the frequency of complications are analysed.
