- The regular textbooks and Journals of gross anatomy and surgery offered much precise information concerning the points at which the branches of the abdominal aorta arise in relation to the vertebrae. But no one aimed to furnish such information on Koreans.
So a study of 116 Korean adults cadavers from which were collected data upon the position of the abdominal aortic branches, and of the aortic bifurcation in relation to the upper, middle, and lower thirds of vertebrae, was performed. The results were as follows:
1. The inferior phrenic artery arose somewhat more frequently directly from the aorta (46.8%) than the coeliac trunk (43.6%) and renal artery (7.4%) on right side, and on the contrary, more frequently from the coeliac trunk (51.1%) than directly from the aorta (47.9%) on left side.
The most frequent origin of the inferior phrenic artery was opposite the 3ower-thirds of the twelvth thoracic vertebrae in both sides (24.2% or 24 of 99 sides in toto)
2. The coeliac trunk arose most frequently at the level of the intervertebral fibrocartilage between the twelvth thoracic and first lumbar vertebrae (25.9%).
3. The superior mesenteric artery arose most frequently opposite the middle-thirds of the first lumbar vertebrae (24.1%). The coelico-raesenteric trunk occurred in 2.6%.
4. The most frequent origin of the middle suprarenal artery was opposite the lower-thirds of the first lumbar vertebrae in both sides (26.0% or 26 of 100 sides in toto).
5. The level of the height of both sides of the renal artery was asymmetric in 41.4% and the right side was highier in 64.6% of that. The accesory renal artery was encountered in 18,9% (22/116) of the specimens and more common in left side.
The most frequent origin of the renal artery was opposite the intervertebrae fibrocartilage between the first and second lumbar vertebrae in both sides (24.6% or 57 of 232 sides),
6. The most frequent origin of the gonadal artery was opposite the intervertebral fibrocartilage between the second and third lumbar vertebrae (19.6% or 10 of 51) in right and opposite the middle-thirds of the second lumbar vertebrae (17.2% or 10 of 58) in left.
7. The inferior mesenteric artery arose most frequently at the level of the intervertebral fibrocartilage between the thirds and fourth lumbar vertebrae (22.4%).
8. The bifurcation of aorta in 35.7% of the specimens occurred in the level of the intervertebral fibrocartilage between the forth and fifth lumbar vertebrae.
