【摘要】：目的旨在证实骶外侧动脉第一背侧支是骶髂关节背侧的供血动脉,应用多普勒超声探测该血管的正常血流动力学表现。方法对一具尸体进行解剖,明确骶外侧动脉第一背侧支的来源、分支及其供血区。再对50名志愿者行骶外侧动脉第一背侧支多普勒超声探测,测量其血流动力学数据,包括收缩期峰值流速(PSV)、舒张末期流速(EDV)和阻力指数(RI),比较不同性别间和左右两侧间骶外侧动脉第一背侧支的PSV、EDV和RI。由两位超声科医师对30名志愿者进行重复测量,分析测量值的可重复性。结果在解剖的尸体标本中,骶外侧动脉发出第一背侧支,经第一骶前孔由骶后孔穿出,随后发出分支进入骶骨外侧滋养孔。50名志愿者的100根骶外侧动脉第一背侧支均成功被探测到,其频谱呈高阻单向波形。骶外侧动脉第一背侧支的PSV为(29.3±4.1)cm/s,EDV为(5.3±1.1)cm/s,RI为0.82±0.04。男、女性志愿者间骶外侧动脉第一背侧支的PSV、EDV和RI的差异均无统计学意义(P值均0.05),志愿者左、右两侧间骶外侧动脉第一背侧支的PSV、EDV和RI的差异均无统计学意义(P值均0.05)。两位医师测得的:PSV、EDV和RI的组内相关系数分别为0.80、0.80和0.88,Bland-Altman图显示,除1名志愿者测得的PSV外,两位医师对骶外侧动脉第一背侧支血流动力学测量值的差值均位于95%的一致性界限内,表明两位医师的测量值的可重复性较好。结论骶外侧动脉第一背侧支是骶髂关节背侧的供血动脉,多普勒超声能有效探测该血管血流动力学表现。
[Abstract]:Objective to confirm that the first dorsal branch of the lateral sacral artery is the blood supply artery of the sacroiliac joint. The origin, branch and blood supply area of the first dorsal branch of the lateral sacral artery were determined. The hemodynamic data of the first dorsal branch of the lateral sacral artery were measured by Doppler ultrasound in 50 volunteers. Including peak systolic flow velocity (PSV), end-diastolic flow velocity (EDV) and resistance index (RI), the PSV of the first dorsal branch of the lateral sacral artery was compared between the sexes and between the left and right sides. EDV and RI. 30 volunteers were measured repeatedly by two ultrasound physicians to analyze the repeatability of the measured values. Results the first dorsal branch of the lateral sacral artery was found in the autopsy cadavers. Through the first anterior sacral foramen through the posterior sacral foramen, the 100 first dorsal branches of the lateral sacral artery were detected successfully in all the 100 volunteers who then issued branches into the lateral sacral trophoblastic foramen. The PSV of the first dorsal branch of the lateral sacral artery was 29.3 卤4.1 cm / s, and the PSV of the first dorsal branch of the lateral sacral artery was 5.3 卤1.1 cm / s. RI was 0.82 卤0.04. There was no significant difference in EDV and RI between male and female volunteers in the first dorsal branch of the lateral sacral artery (P < 0.05). There was no significant difference of PSV EDV and RI in the first dorsal branch of the lateral sacral artery between the right and the right sides (P = 0.05). The intra-group correlation coefficients of EDV and RI were 0.80 and 0.88Bland-Altman, respectively, except for the PSV measured by one volunteer. The difference in hemodynamic measurements of the first dorsal branch of the lateral sacral artery between the two physicians was within the consistent limit of 95%. Conclusion the first dorsal branch of the lateral sacral artery is the blood supply artery of the sacroiliac joint, and Doppler ultrasound can effectively detect the hemodynamic manifestation of the blood vessel.
