The treatment of type A acute aortic dissection is a challenge for the surgeon, and serious late-complications may occur even after surgical repair. We report treatment following a type A post-dissection thoraco-abdominal aneurysm in a patient who previously underwent ascending aortic reconstruction using a biological aortic valve and Dacron prosthetic graft implantation in emergency conditions. The multi-staged approach consisted in removing the right kidney and performing a heterotopic autotransplantation in the left iliac fossa before positioning a fenestrated endograft (celiac trunk, superior mesenteric artery and left renal artery).

Current management of aortic aneurysms relies exclusively on prophylactic operative repair of larger aneurysms. Great potential exists for successful medical therapy that halts or reduces aneurysm progression and hence alleviates or postpones the need for surgical repair. Preclinical studies in the context of abdominal aortic aneurysm identified hundreds of candidate strategies for stabilization, and data from preoperative clinical intervention studies show that interventions in the pathways of the activated inflammatory and proteolytic cascades in enlarging abdominal aortic aneurysm are feasible.

Abdominal aortic aneurysm (AAA) is a local dilatation of the abdominal aortic vessel wall and is among the most challenging cardiovascular diseases as without urgent surgical intervention, ruptured AAA has a mortality rate of >80%. Most patients present acutely after aneurysm rupture or dissection from a previously asymptomatic condition and are managed by either surgery or endovascular repair. Patients usually are old and have other concurrent diseases and conditions, such as diabetes mellitus, obesity, and hypercholesterolemia making surgical intervention more difficult. Read More

Dissections or ruptures of aortic aneurysms remain a leading cause of death in the developed world, with the majority of deaths being preventable if individuals at risk are identified and properly managed. Genetic variants predispose individuals to these aortic diseases. In the case of thoracic aortic aneurysm and dissections (thoracic aortic disease), genetic data can be used to identify some at-risk individuals and dictate management of the associated vascular disease.

Aortic aneurysms are a common vascular disease in Western populations that can involve virtually any portion of the aorta. Abdominal aortic aneurysms are much more common than thoracic aortic aneurysms and combined they account for >25 000 deaths in the United States annually. Although thoracic and abdominal aortic aneurysms share some common characteristics, including the gross anatomic appearance, alterations in extracellular matrix, and loss of smooth muscle cells, they are distinct diseases.

Neoplasias affecting the aorta are usually due to a variety of thoracic and abdominal tumours, which are more common than primary tumours of the aortic wall. Those tumors that can invade the abdominal aorta are usually sarcomas, which are able to mimic, both clinically and radiologically, an aortic disease such as an aneurysm or a dissection. There are few clinical scenarios where surgical resection and aortic repair needs to be performed, and indications have not still been clearly established in the literature. Read More
