Abstract

The contemporary incidence and prevalence of thoracic aortic aneurysm and dissection (TAAD) remains understudied. Epidemiological research on TAAD has been limited by incomplete case identification within administrative data sources. The objectives of this study were to develop a case identification method and determine the incidence and prevalence of TAAD, based on data from Manitoba, Canada. Hospital records and medical claims housed at the Manitoba Centre for Health Policy, and data from the Manitoba Thoracic Aortic Diseases Clinic were used to develop a case definition and identify patients with TAAD in Manitoba, Canada. The age-standardized incidence and prevalence of thoracic aortic disease was determined and stratified by sex from 1998 to 2016. We identified 4264 patients with TAAD, of whom 63% were male. The age standardized incidence was 2 times higher in men, peaking at 42 cases per 100,000 in 2013. Although the overall incidence was lower in female patients, the number of incident cases increased 68% compared with 25% in male patients. In hospitalized patients, the incidence and prevalence of aneurysms increased over time, whereas the incidence of dissection and rupture has remained stable. The use of a novel case id...Continue Reading

Aneurysm

Aneurysms are outward distensions or bulges that occurs in a weakened wall of blood vessels. Discover the latest research on aneurysms here.

Cardiac Aneurysm

Aneurysm refers to a bulge of the wall or lining of a vessel commonly occurring in the blood vessels at the base of the septum or within the aorta. In the heart, it usually arises from a patch of weakened tissue in a ventricular wall, which swells into a bubble filled with blood. Discover the latest research on cardiac aneurysm here.

Aortic Aneurysm

An aortic aneurysm is the weakening and bulging of the blood vessel wall in the aorta. This causes dilatation of the aorta, which is usually asymptomatic but carries the risk of rupture and hemorrhage. Find the latest research on aortic aneurysms here.
