摘要
目的:通过对腹壁下动脉、冠状动脉及主动脉-冠状动脉桥进行测量,为临床医生应用腹壁下动脉于冠状动脉旁路移植术中提供解剖学及血流动力学资料。方法:应用解剖方法,对腹壁下动脉长度和外径、冠状动脉各外径及主动脉-冠状动脉桥的长度进行测量;应用彩色多普勒超声诊断仪对腹壁下动脉及冠状动脉的管径、血流速度进行测量。结果:解剖下腹壁下动脉长度为(13.00±2.58)cm,其起始处管径为(2.95±0.21)mm,与腹直肌外缘相交处管径为(2.51±0.32)mm,脐下1.0cm处管径为(1.60±0.26)mm。彩色多普勒超声下腹壁下动脉起始处内径为(2.98±0.37)mm,距起始5cm处内径为(2.60±0.27)mm,血流速度为(57.00±6.78)cm/s;左冠状动脉主干管径为(4.90±0.76)mm,右冠状动脉主干管径为(3.58±0.63)mm,血流速度为(48.50±7.72)cm/s;主动脉-冠状动脉桥的长度为(10.95±1.35)^(15.30±2.82)cm。结论:腹壁下动脉用于游离移植能桥接主动脉与冠状动脉左前降支、左回旋支、右冠状动脉主干,其管径、血流速度与冠状动脉管径、血流速度相匹配;应用彩色多普勒超声诊断术前可对腹壁下动脉作为移植血管的安全性进行评估,为临床随访提供一种新的无创方法。
Objective To measure the inferior epigastric artery (lEA) , coronary artery and arterial bridge to supply the anatomic and hemodynamic data of lEA in coronary artery bypass grafting for clinicians. Methods Anatomic method was adopted to measure the length of lEA, arterial bridge, the outer diameter of lEA and coronary arteries. Colour doppler ultrasound instrument was adopted to measure the caliber and the blood flow rate of lEA and coronary artery. Results In the anatomic method, the length of lEA was ( 13.00 ± 2.58 ) cm and the caliber of original lEA was (2.95 ± 0.21 ) mm, the caliber of lEA intersecting with abdomen rectus was ( 2.51 ±0.32 ) mm, and ( 1.60 ± 0.26 ) mm at 1.0 cm below the umbilicus. In color doppler ultrasound method, the caliber of original lEA was (2.98 ± 0.37) mm, and at 5 cm from the original spot was (2.60 ± 0.27) mm. The blood flow rate was (57. 00 ±6.78) cm/s. The main stem caliber of the left coronary artery was (4.90 ± 0.76 ) mm, and that of the right coronary artery was ( 3.58 ±0.63 ) mm; the blood flow rate was (48. 50 ± 7. 72 ) cm/s. The length of the arterial bridge was ( 10.95± 1.35 ) - ( 15.30 ±2.82 ) cm. Conclusion lEA can bridge the aorta and the coronary artery branches including the left anterior descending branch, the left circumflex branch and the right main coronary artery in free grafting. Its caliber and blood flow rate can match with those of the coronary artery. Before the operation of applying color doppler ultrasound instrument, the safety of IEA in the coronary artery bypass grafting can be evaluated to provide a new safe method in clinical followup.
