Secondary Rupture of Aortic Aneurysm Post EVAR

Aortic Aneurysm

Post-stent rupture of the abdominal aorta is a rare occurrence and with few publications: only 2 multicenter studies and one meta-analysis in 2017 listed this complication As well as a few cases reports This study, the first carried out in France, aims to describe the survival in patients with secondary rupture of the aneurysm despite initial treatment with EVAR.

Prediction of Acute Kidney Injury After Operation of Acute Type A Aortic Dissection Based on Multimodal...

AneurysmDissecting1 more

Acute kidney injury is one of the most common postoperative complications of acute type A aortic dissection, which is closely related to early postoperative death. Early prevention, early diagnosis and early treatment are the key to improve the prognosis of such patients. It has been a hot topic in clinical research for a long time. Previous reports revealed a series of risk factors for acute kidney injury after aortic dissection, but limited by research design and single modal data, high quality studies were rare. The purpose of this study is to further clarify the risk factors by studying the relationship between preoperative CT renal perfusion imaging indexes and postoperative acute kidney injury; establish and externally verify the multimodal radiomics prediction model for acute kidney injury after operation of aortic dissection combining with preoperative CT renal perfusion imaging and CT angiography information by analysis methods of information fusion, feature engineering and radiomics, so as to guide the follow-up clinical practice, improve the prognosis of such patients and save medical resources.

Pituitary Dysfunction After Aneurysmal Subarachnoid Hemorrhage

Thyroid DisfunctionSubarachnoid Haemorrhage From Cerebral Aneurism Rupture1 more

Recently, the occurrence and potential impact of pituitary dysfunction after aSAH has gained increasing interest. Several studies have demonstrated pituitary dysfunction after SAH suggesting that pituitary dysfunction may be a contributing factor for residual symptoms after SAH. This is an observational multicentric study aimed to test the prevalence of thyroid abnormalities, other neuroendocrinological dysfunction and their influence on outcome of patients affected by aSAH.

Abdominal Compartment Syndrome and Ruptured Aortic Aneurysm : Validation of a Predictive Test

Abdominal Compartment Syndrome

It is an observational study on ruptured abdominal aortic aneurysm and abdominal compartment syndrome. the aim of this study is to assess the qualities of a predictive score on the occurence of this syndrome after surgery of ruptured aortic aneurysm

Incidence and Effects of Sleep Apnea on Intracerebral Aneurysms

Sleep Apnea (Defined as Apnea Hypopnea Index > 5/h)Intracranial Aneurysm Size3 more

Patients with intracerebral aneurysm will be screened for sleep apnea using out of center polysomnography/polygraphy. Baseline blood pressure and medication will be assessed. Patients will be followed for up to 5 years to examine the increase in aneurysm size, rupture rate and changes in medication.

Chronic Q-fever in Patients With an Abdominal Aortic Disease (QAAD-study)

Chronic Q-feverAortic Aneurysm4 more

Q-fever is a zoonosis caused by Coxiella burnetii, an intracellular bacterium. Since the epidemic outbreak of acute Q-fever in Holland nearly 4030 people have been registered with the acute form of the disease. Knowing that only 40% of all infected people develop symptoms, the number of infected people (and potential candidates for chronic Q-fever) are much higher. Chronic Q-fever generally manifest itself after a couple of months or years after the primary infection (in 1-5% of all cases). The clinical presentation can be a life-threatening and frequently underdiagnosed disease, as endocarditis, infected aneurysm and vascular prosthesis or chronic Q-fever related to pregnancy and immunecompromised patients. That's why a screening program is started in the endemic area and trace patients with chronic Q-fever. So eventually, a greater group of patients with chronic vascular Q-fever can be described. In addition, there is still no therapeutic guideline for management of chronic Q-fever in patient with a vascular chronic Q-fever. Patients with an aneurysm or vascular graft will be screened for chronic Q-fever. Patients with chronic Q-fever will be included in a follow-up program, in which additional research and treatment will start. The initial treatment of patients with chronic Q-fever is doxycycline and hydroxychloroquine for at least 18 months. In addition, patients will be monitored in 3-monthly controls, blood samples and imaging will be done. Parameters as complaints, titers, circulating DNA, grow of aneurysm, complications etc. will be investigated. Ultimately, the current therapeutic guideline for management of C. burnetii will be evaluated if it can also be applied for patients with vascular chronic Q-fever.

White Blood Cell Counts and Onset of Cardiovascular Diseases: a CALIBER Study

Abdominal Aortic AneurysmCoronary Artery Disease3 more

The complete blood count is a commonly performed blood test, and previous small studies have suggested that the counts of some types of white blood cell in the complete blood count may be related to the onset of cardiovascular diseases such as stroke and heart attack. This is of interest because this information may help to predict strokes or heart attacks and may guide new therapies which act on white blood cells to reduce the risk of cardiovascular disease. The hypothesis is that counts of particular types of white blood cell are associated with a range of cardiovascular diseases.
