The main objective of the treatment is the patient survival. Thus, the surgeon has to perform a well-mastered surgical technique without extending the operative time and emphasizing operative risk. Nevertheless, patients with history of TAAD present long-term complications on the aorta, mainly aneurysmal evolution and dissection recurrence. In order to decrease the long-term excess mortality of this population, it is necessary to respect some rules during the surgery. Concerning the proximal segment of the ascending aorta, the aortic root has to be replaced by a composite graft (Bentall technique) or a valve sparing inclusion (David technique) when the dissection reaches the sinuses of Valsalva or when aortic valve regurgitation is observed. Concerning the distal segment of the ascending aorta, the distal anastomosis has to be performed without aortic clamp-ing. Concerning the descending thoracic aorta, hybrid surgery should be performed on patients with malperfusion syndrome and patients with high risk factors for aneurysmal evolution.","PeriodicalId":258976,"journal":{"name":"Aortic Aneurysm and Aortic Dissection","volume":"107 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123235506","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among the several factors related to high mortality, imaging methods and intervention procedures could be important. The commonly used diagnostic imaging methods of aneurysms are computed tomography (CT), magnet resonance imaging (MRI), ultrasound (US), digital subtraction angiography (DSA) and amalgamation of fluoro-D-glucose (FDG) integrated with positron emission tomography (PET) and/or CT and PET with CT or MRI. Several research findings indicate that diagnostic efficiency of different imaging methods differ. As intervention procedures depend upon diagnosis, the choice of appropriate diagnostic imaging method for a given case is very important. If the critical characteristics of the swelling are not detected due to the choice of unsuitable imaging method, interventions may not be very suitable. The American College of Radiologists (ACR) prescribed some appropriateness guidelines for diagnostic imaging. Not complying with them fully or partially may also be a mortality factor. This chapter is written with recent research findings in the field of intelligent data analysis for medical applications supported by case studies and practical examples.","PeriodicalId":258976,"journal":{"name":"Aortic Aneurysm and Aortic Dissection","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130701357","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In particular, the infusion of angiotensin II (Ang II) in hyperlipidemia mice to induce AAA and TAA has been extensively used in the field, suggesting a critical role of Ang II in aortic aneurysm. In contrast, whether aldosterone (Aldo), a downstream effector of Ang II, is involved in aortic aneurysm is unknown. Here, we describe a new mouse model of AAA and TAA induced by subcutaneous implantation of deoxycorticosterone acetate (DOCA) pellets or infusion of Aldo using osmotic pumps to 10-month-old C57BL/6 male mice in the presence of high salt. The DOCA- or Aldo-salt-induced aortic aneurysm is dependent upon mineralocorticoid receptor activation but independent of Ang II and hypertension and exhibits several unique features that mimic human aortic aneurysm. This review aims to discuss the common animal models of AAA, TAA, and aortic dissection currently studied in the world with the most focus on the DOCA- or Aldo-salt mouse model of aortic aneurysm. significance and potential impact of the DOCA- or Aldo-salt mouse model of aortic aneurysm on the current basic research and clinical practice on the etiology, clinic diagnosis, evaluation, and treatment of AAA.","PeriodicalId":258976,"journal":{"name":"Aortic Aneurysm and Aortic Dissection","volume":"90 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126064427","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
