This report describes an anomalous case of the multiple ipsilateral common trunk formation in the parietal arteries encountered during observed in the dissection of a 71 year-old Japanese female cadaver in the anatomical laboratory of Kanazawa Medical University. This subject had thirteen parietal arteries. Among the thirteen parietal arteries two arose from both the subclavian arteries (superior intercostal artery), and eleven arose from the descending aorta (aortic parietal arteries). Five arteries (R-1-R-5) were located on the right side, and eight (L-1-L-8) on the left. Of the eleven aortic parietal arteries, nine formed the ipsilateral common trunk, and the other two were independent branches (left 11th intercostal and 2nd lumbar arteries). The branching states of these parietal arteries were as follows: on the right side, R-1 was the common trunk for the 1st and 2nd intercostal arteries (the right superior intercostal artery), R-2 (was the common trunk) for the 3rd, 4th, 5th, 6th and 7th intercostal arteries, R-3 for the 8th and 9th intercostal arteries, R-4 for the 10th and 11th intercostal arteries and R-5 for the subcostal, 1st, 2nd, 3rd and 4th lumbar arteries. On the left side, L-1 was the common trunk for the 1st and 2nd intercostal arteries (the left superior intercostal artery), L-2 for the 3rd, 4th and 5th intercostal arteries, L-3 for the 6th and 7th intercostal arteries, L-4 for the 8th, 9th and 10th intercostal arteries, L-6 for the subcostal and 1st lumbar arteries, and L-8 for the 3rd and 4th lumbar arteries.(ABSTRACT TRUNCATED AT 250 WORDS)
本报告描述了在金泽医科大学解剖实验室对一名71岁日本女性尸体进行解剖时，所观察到的一种异常情况，即顶叶动脉出现多条同侧总干形成。该受试者有13条顶叶动脉。在这13条顶叶动脉中，两条起源于锁骨下动脉（肋间上动脉），11条起源于降主动脉（主动脉顶叶动脉）。5条动脉（R - 1 - R - 5）位于右侧，8条（L - 1 - L - 8）位于左侧。在11条主动脉顶叶动脉中，9条形成同侧总干，另外两条是独立分支（左第11肋间动脉和第2腰动脉）。这些顶叶动脉的分支情况如下：在右侧，R - 1是第1和第2肋间动脉的总干（右肋间上动脉），R - 2是第3、4、5、6和第7肋间动脉的总干，R - 3是第8和第9肋间动脉，R - 4是第10和第11肋间动脉，R - 5是肋下动脉、第1、2、3和第4腰动脉。在左侧，L - 1是第1和第2肋间动脉的总干（左肋间上动脉），L - 2是第3、4和第5肋间动脉，L - 3是第6和第7肋间动脉，L - 4是第8、9和第10肋间动脉，L - 6是肋下动脉和第1腰动脉，L - 8是第3和第4腰动脉。（摘要截断于250字）
