Tortuous aorta vs normal aorta.

The descending thoracic aorta (DTA) was analyzed and was divided into four zones of equal length. Subjects were divided into three groups based on their maximum tortuosity value: low (< 30°), moderate (30° – 60°) and high (> 60°). A linear regression model was built to test the effect of age and gender on tortuosity. Normal aorta – 27-year-old. Hover on/off image to show/hide findings. Tap on/off image to show/hide findings.

The aorta tapers distally, with the normal descending aorta always smaller in caliber than the ascending aorta in healthy individuals. The proximal descending aorta is considered abnormal when it exceeds 2.63 cm, and the distal descending aorta is considered abnormal when it exceeds 2.43 cm in diameter [ 7 , 8 ].

The diameter of your aorta varies based on your age, body surface area and sex assigned at birth. But researchers agree these are the normal values: Normal thoracic descending aorta size: Less than 1.6 centimeters/square meters of body surface area. Normal abdominal descending aorta size: Less than 3 centimeters (approximately 2 centimeters).This iceberg knows it looks like a sheet cake but it would like you to leave it alone.

Aortic coarctation (ko-ahrk-TAY-shun) is a narrowing of the aorta. It forces the heart to pump harder to move blood through the aorta.
