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.

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.

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.

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.

The Coexistence of Atherosclerotic Intracranial Arterial Stenosis With Intracranial Aneurysms

Atherosclerotic Intracranial Arterial Stenosis With Intracranial Aneurysms

Atherosclerotic intracranial arterial(ICA) stenosis and intracranial aneurysms are the common causes of ischemic stroke and hemorrhagic stroke, respectively. Investigators aimed to assess the prevalence of cerebral aneurysms in patients with atherosclerotic intracranial arterial stenosis.
