Anatomical consideration of the acupuncture into the stellate ganglion / 全日本鍼灸学会雑誌

ABSTRACT

The anatomical structures penetrated by a needle which was inserted in an acupuncture point into the stellate gaglion, 1.5cm lateral to and 2.5cm above the point Tentotsu, were studied bilaterally with dissection of 19 cadavers. Furthermore, the size of the dissected stellate ganglion, its anatomical position, and its positional relation to structures located near it were measured or observed.<br>Though 8 out of 38 inserted needles pricked the medial margin of the ganglion, the remaining 30 needles all missed medially from the ganglion. In the cases pricking the ganglion, all of 8 needles penetrated either the vertebral or the subclavian artery before reaching the ganglion, and 7 of these did also the dome of the pleura in addition to the artery. In the cases missing from the ganglion, however, a frequency of penetrating the above structures were considerably lower.<br>The dissected stellate ganglion almost lay on beteen the mid-level of the vertebral body of the 7th cervical vertebra and the upper level of body of the second thoracic vertebra, with their mean size 27.1, 7.7 and 2.8mm in length, width and thickness, respectively. All of the ganglions were located dorsal to the vertebral and subclavian arteries and the dom of the pleura the distances from the median line to their upper and lower extremity being 21.9 and 22.7mm in average, respectively.<br>The pricked point for directly aiming at the stellate ganglion from the body surface is within a range 20 to 30mm lateral to and 10 to 40mm above the point tentotsu on the right, and on the left it is within a range 15 to 25mm lateral and 10 to 35mm above; the depth from the point is about 4.0 and 3.8cm on the right and left, respectively. But when directly aiming at the ganglion, the possibility of injuring the vertebral or subclavian artery and the dome of the pleura was suggested to increase considerably owing to their location ventral to the ganglion.
