endovascular devices and techniques will evolve to expand applicability and provide therapy for most aortic diseases, including a growing number of diseases of the arch and the ascending aorta [4]. Complex aortic aneurysms that involve major aortic branch origins include those juxtaposed or involving the renal arteries (juxtarenal, perirenal), the visceral arteries (thoraco-abdominal) and the g...

Most aortic aneurysms are detected incidentally in patients presenting for other illnesses. The prevalence of thoracic aortic aneurysms is in the order of 3-4% in individuals older than 65 years. Aneurysms of the thoraco-abdominal aorta are primarily due to atherosclerotic degenerative disease (80%) and due to chronic aortic dissection in the remaining 20%. The morbidity and mortality from aort...

An aneurysm is defined as a localized dilatation of a vessel of 50% of the normal diameter and includes all layers of the given vessel.1 Aortic aneurysms are divided into thoracic aortic aneurysms (TAAs), thoracoabdominal aortic aneurysms (a thoracic aneurysm extending into the abdomen), and abdominal aortic aneurysms (AAAs). Abdominal aortic aneurysms are reportedly more common than TAAs. Demo...

OBJECTIVE The aim of this study was to describe our early experience in the treatment of ruptured abdominal aortic aneurysms with bifurcated endografts. We report on our initial twelve-month experience using this approach. METHODS Clinical data on patients with ruptured abdominal aortic aneurysms treated at a single tertiary center in Brazil were prospectively recorded. The eligibility for en...

Aneurysms were first described by Gallen in the second century. It was only in the twentieth century that Dubost I in France first excised an abdominal aortic aneurysm and replaced it with a graft. Since then, over the past 25 years, there have been rapid advances both in the field of prosthetic materials and technical approaches in the surgical management of abdominal aortic aneurysms and now,...

Mycotic aortic aneurysms account for 1–3% of all aortic aneurysms. The management of this disease is controversial. Since open surgical repair is associated with high morbidity and mortality rates, endovascular aneurysm repair is an alternative treatment method with promising early and midterm outcomes, although its long-term durability is unknown.Secondary aortoenteric fistulas may occur iatro...

We, as well as other authors, believe that the retroperitoneal approach is an excellent alternative to the transperitoneal route for the repair of abdominal aortic aneurysms. This approach is associated with a significant decrease in pulmonary and cardiac complications and therefore can be used in selected high-risk patients with expanding aneurysms. A well-controlled randomized multicenter tri...

Isolated common iliac artery aneurysms are rare, comprising <2% of all aneurysm disease. These aneurysms present as either isolated disease, .03% of the population, or, in conjunction with abdominal aortic aneurysm, in approximately 20% to 25% of such cases. Common iliac artery aneurysms are defined as any localized dilatation of the common iliac artery >1.5 cm in diameter. Elective repair for ...

Osmotic pumps continuously deliver compounds at a constant rate into small animals. This article introduces a standard protocol used to induce aortic aneurysms via subcutaneous infusion of angiotensin II (AngII) from implanted osmotic pumps. This protocol includes calculation of AngII amount and dissolution, osmotic pump filling, implantation of osmotic pumps subcutaneously, observation after p...

Dear Editor,Abdominal aortic aneurysm is often asymptomatic, less recognized, and causes considerable mortality and morbidity, if missed. The incidence varies from country to country and the occurrence is influenced by modifiable (smoking, coronary heart disease, hypertension, dyslipidemia, and prolonged steroid therapy) and non-modifiable risk factors (increasing age, male gender, and positive...
