The length of the aorta from the subclavian artery to the renal artery based on computed tomographic measurements in Japanese adults

Abstract

To estimate the length of the aorta from the subclavian artery to the renal artery in Japanese adults, its length was measured on computed tomographic (CT) images. Data from a total of 110 patients without aortic or aortic valvular diseases (54 men, 56 women) who had undergone 7-mm-slice-interval CT examination of the entire aorta was analyzed in this study. The length of the aorta was found to be 214.1 +/- 20.7 mm and showed a positive correlation with height (r = 0.664). Especially, the length of the aorta in male patients was correlated with body mass, i.e., height, weight, and body surface area. From these results, it appears that the majority of commercially available intra-aortic balloon catheters are too long for use in the Japanese population. It is concluded that a shorter, more suitable catheter should be made available for safe use in Japanese patients.

Visceral Arterial Compromise During Intra-Aortic Balloon Counterpulsation Therapy

“…In an autopsy study on cardiac surgery patients, however, IABP use was a significant risk factor for the development of lethal mesenteric ischemia. 22,23 The high rate of laparotomy and bowel resection for mesenteric ischemia found in our study, as well as preliminary experimental flow measurements, suggests that balloon malposition is causally related to visceral malperfusion. Beside diastolic hypoperfusion, atherosclerotic embolic debris caused by mechanical interaction between the balloon and the aortic wall may be related to visceral ischemia.…”

“…21,22 Careful survey of the CT scans revealed senile degeneration and sintering of the vertebral bodies in 43% of the patients, which may be contributory to shrinkage of the thoracolumbal backbone and shortening of the longitudinal aortic axis, respectively. Thus, patient height alone appears to be not sufficient to guide for balloon sizing and to avoid anatomic-to-device length mismatch.…”

“…However, this group may not be representative of broader populations. Fortunately, aortic morphometry seems to be more influenced by height and/or torso length than ethnic background. This means that we can interpret the general population from a height and/or torso length point of view, and given our cohort’s diversity (height ranged from 150 to 198 cm), it is reasonable to believe that our results are applicable to patients with the same demographic characteristics as our cohort, regardless of their ethnic background.…”
