研究主动脉及其大血管分支解剖变异不仅在外科领域中极为重要,而且可以解释某些病例的临床症状,如变异的锁骨下动脉造成的食管受压症状等。 作者5年来共做了819例动脉造影术,仔细观察了主动脉及其分支血管的解剖位置,尤其是头臂动脉,锁骨下动脉,颈总动脉以及椎动脉的起源。 结果:705例中有629例(89.2％)显示了正常的解剖位置,即从右向左为头臀动脉,左颈总动脉左锁骨下动脉分别起源于主动脉弓,76例(10.8％)有解剖异常,概括为7种不同类型的变异,其中最常见的是52例占68.4％为大臂动脉与左颈总动脉共干分出;其次18例占23.7％为左颈总动脉由头臂动脉分出。其他的变异是2例双头臂动脉;1例异常的右锁骨下动脉起于左颈总动脉的内侧面;1例左椎动脉在头臂动脉与左颈总动脉之间起于主动脉弓;1例头臂动脉与左颈总动脉共干分出,伴有左椎动脉在头臂动脉与左锁骨下动脉之间起于主动脉弓;1例左右锁骨下动脉共干分出,伴有右颈总动脉在左颈总动脉远侧起于主动脉弓。
Studying anatomic variations of the aorta and its large blood vessel branches is not only important in the surgical field, but can also explain clinical symptoms in some cases, such as esophageal compression symptoms caused by a variant subclavian artery. In the past 5 years, a total of 819 patients underwent angiography. The anatomic locations of the aorta and its branches, especially the brachiocephalic, subclavian, common carotid and vertebral arteries, were carefully observed. RESULTS: Of the 705 patients, 629 (89.2%) showed normal anatomic locations, ie, the right hip artery from right to left, the left subclavian artery of the left common carotid artery originated from the aortic arch, and 76 (10.8%) had anatomy Abnormal, summarized as seven different types of variation, of which the most common is 52 cases accounted for 68.4% of the common carotid artery and left common carotid artery; followed by 18 cases accounted for 23.7% of the left common carotid artery by the brachial artery points Out The other variants were two cases of double-brachiocephalic artery; one case of abnormal right subclavian artery originated from medial side of left common carotid artery; one case of left vertebral artery originated from aortic arch between the brachiocephalic artery and left common carotid artery; 1 Cases of the first arm artery and left common carotid artery were co-stem separation, accompanied by the left vertebral artery in the brachiocephalic artery and the left subclavian artery in the aortic arch; 1 case of subclavian artery were co-stem separation, accompanied by right neck total The artery originates from the aortic arch distal to the left common carotid artery.
