(20) Adrenal tissue should be preserved whenever possible.
Suprarenal
Definition:
(a.) Situated above, or anterior to, the kidneys.
(n.) A suprarenal capsule.
Example Sentences:

(4) The 6.8% of patients requiring suprarenal aortic cross-clamping had a higher incidence of postoperative renal dysfunction (p = 0.02) and intraoperative blood loss (p less than 0.001), but cardiac events were not more frequent.
(5) The aneurysms in the black group were distributed as follows: 50 aortic (9 suprarenal, 41 infrarenal), 6 common iliac artery, 2 superior mesenteric and 2 renal artery aneurysms.
(6) This is particularly the case in the upper abdomen, where the differentiation between renal, suprarenal, pancreatic and splenic lesions has been difficult.

(8) The operative treatment of 77 patients with atherosclerotic aneurysms of the pararenal aorta (54 juxtarenal and 23 suprarenal) is analyzed.
(9) These results demonstrate that transport and racing are different kinds of stressors, suggesting that the sympathetic system and hypophysis-suprarenal cortex axis have a dissimilar contribution to the physiological response.
(10) Experience with specific injuries is reviewed with commentary on surgical access to difficult areas including the thoracic outlet, suprarenal aorta and inferior vena cava.
(11) Two hundred five patients who underwent elective abdominal aortic aneurysm repair were divided into two groups: those who underwent infrarenal cross-clamping alone (n = 166) and those who underwent suprarenal cross-clamping alone or combined with infrarenal cross-clamping (n = 39).
(12) From these results, we conclude that the initial increase in upper body arterial blood pressure seen after suprarenal aortic blood flow reduction is dependent upon the renin-angiotensin system.
