目的
2
观察闭孔动脉(OA)的起源及走行,为减少盆腔内手术以及耻骨骨折固定时出血量提供解剖学参考依据。
方法
2
解剖65例结构完整的人体半骨盆标本,观察OA的起源、走行等变异情况;测量OA盆内段长度、起始处外径等。
结果
2
OA起源于髂内动脉57例(87.7%),其中臀上动脉3例(4.6%),臀下动脉5例(7.7%),髂外动脉3例(4.6%),腹壁下动脉5例(7.7%);OA参与形成动脉干3例(4.6%)。男、女性OA盆内段长度分别是(50.87±15.41)mm、(51.71±14.19)mm,二者比较差异无统计学意义(
P
>
0.05);男、女性OA起始处外径分别是(2.79±1.05)mm、(2.35±0.86)mm,二者比较差异无统计学意义(
P
>
0.05)。
结论
2
OA主要起源于髂内动脉前干,少数OA起自后干的分支或腹壁下动脉,或参与形成动脉干。在涉及OA区域的盆腔手术中,应重视其盆内段长度及起始处外径,便于术中更好地定位和保护血管。
Objective
2
To observe the origin and course of the obturator artery (OA), so as to provide anatomical reference for reducing hemorrhage during pelvic surgery and pubic fracture fixation.
Methods
2
A total of 65 human hemi-pelvises specimens with intact structure were dissected to observe the origin, course and other variations of OA. Measure the length of the inner section of OA basin and the outer diameter at the origin, etc.
Results
2
OA originated from the internal iliac artery in 57 cases (87.7%), including 3 cases (4.6%) of the superior gluteal artery, 5 cases (7.7%) of the inferior gluteal artery, 3 cases (4.6%) of the external iliac artery and 5 cases (7.7%) of the inferior epigastric artery. OA participated in the formation of the arterial trunk in 3 cases (4.6%). The length of the pelvic segment of the OA in male and female was (50.87±15.41) mm and (51.71±14.19) mm, respectively, with no statistically significant difference between them (
P
>
0.05). The outer diameters at the origin of the OA in male and female were (2.79±1.05) mm and (2.35±0.
86) mm, and there was no statistically significant difference between them (
P
>
0.05).
Conclusion
2
OA mainly originated from the anterior trunk of the internal iliac artery, with a few OA originated from the branches of the posterior trunk or the inferior epigastric artery, or participated in the formation of the arterial trunk. In pelvic surgery involving OA area, attention should be paid to the length of its pelvic segment and the outer diameter at the origin of OA, so as to better locate and protect blood vessels during surgery.
