Abdominal aortic aneurysm rupture rates: A 7-year follow-up of the entire abdominal aortic aneurysm population detected by screening

Abstract

In centers with an operative mortality rate of greater than 2%, (1) surgical intervention is not indicated for asymptomatic AAAs of less than 4.5 cm in diameter, and (2) elective surgery should be considered only for patients with aneurysms between 4.5 and 6 cm in diameter that are expanding by more than 1 cm per year or for patients in whom symptoms develop. In centers with elective mortality rates of greater than 10% for abdominal aortic aneurysm (AAA) repair, the benefit to the patient of any surgical intervention for an asymptomatic AAA of less than 6.0 cm in diameter is questionable.

Endovascular Repair of Abdominal and Thoracic Aortic Aneurysms

“…23 An exception to this guideline is that intervention should be offered despite the size of the aneurysm if symptoms develop or the aneurysm increases in size by 1 cm per year. 24 In addition, if the patient is a woman with smaller native vessels, the relative size that represents aneurysmal disease may be less than the conventional 5 to 5.5 cm range.…”

Stromelysin-1 (Matrix Metalloproteinase-3) and Tissue Inhibitor of Metalloproteinase-3 Are Overexpressed in the Wall of Abdominal Aortic Aneurysms

“…[11][12][13] There is no proven effective treatment for these small aneurysms, and repeated scans are used to monitor the expansion of the aneurysm until the diameter of the aneurysm is Ͼ5.5 cm. At this stage, the risk of rupture is greater than the risk of operation, and surgery is indicated.…”

Efficacy of endovascular management approach of ruptured abdominal aortic aneurysm

“…As a result, is the main factor in the decision to recommend repair or just submit the patient to periodic clinical surveillance. [20][21][22] Several randomized trials have identified the 5cm size limit for the indication of surgical approach open23. However, if there was any procedure with morbidity and survival uniforms, all aneurysms would be treated, regardless of their size.…”
