The Reconstruction Anatomy Study Of Uerine Artery And Varian Artery With Three-dimensional Computed Tomographic Angiography

Objective:On the basis of CTA gathering data,depending on the 3 d reconstruction,observe and measure the relevant anatomy content of uterine artery and ovarian artery.Including origin,open form,initial pipe diameter,contorts the distribution and the relative position of the opening,etc.The study also collected and analyzed the relationship between ovarian arterial development and age.In order to obtain valuable image anatomy data,and provide basic data and support for surgery and interventional therapy in clinical obstetrics and gynecology department and related clinics.Improve the success rate of interventional therapy,reduce intraoperative hemorrhage,reduce surgical accident,and improve the clinical effect.Materials and methods:Selected the patients with CTA scan in the lower abdomen of the first hospital of Jilin University from April 2015 to October 2017.According to selection criteria and exclusion criteria,73 cases were finally selected for data analysis.Using the GE Discovery TM 64 line gems of subjects undergoing abdominal CT machine scanning,with iohexol injection for enhanced agent.The images obtained result is sent to AW Volume Share 4.5 workstation.It was reconstructed by the imaging department of the first hospital of Jilin University,using the three-dimensional reconstruction of blood circulation system and skeletal system and the maximum density projection(MIP)reconstruction.Finally,the reconstruction images were observed and measured,under the guidance of teachers and technicians of the department of clinical imaging and human anatomy.Results:1.The uterine artery which originated from the internal iliac artery was 38 cases(26%);which originated from the anterior branches of internal iliac artery was 92cases(63%);which originated from the perineum branches of gluteal artery was 16cases(11%).2.In 105 cases(72%),the angle between uterine artery and superior blood vessels was acute angle;in 23 cases(16%),it was right angle;and in 18 cases,the origin of uterine artery was spiral.The initial segment of the uterine artery was collected at about 1cm from the starting point of the distance.External diameter of left uterine artery was 2.5±0.3mm,External diameter of right uterine artery was 2.3±0.4mm.3.The uterine artery is issued from the superior blood vessels,and down the medial wall of the pelvis.Then turn to the pelvic cavity,below the uterus.After passing through the uterine fixation device,there are multiple branches.The main branch ascend to provide for uterus and ovary,the descending branch went down to provide for upper vagina.4.The study selected 73 female to check pelvic CTA,only 36 cases(49%)60 sides(41%)can show ovarian artery,among them 24 cases can show both sides.5.The 36 cases 60 sides of the ovary artery selected by this study were all from the front wall of the anterior abdominal aorta,no other origin has been seen.The opening was at first lumbar level,between the upper and lower edge of the vertebral body.In 24 cases which can show both ovarian arteries,7 cases(29%)haved a similar high;in 12cases(50%)the lift opening was higher than right;in 5cases(21%)the right opening was higher then lift.Conclusion:1.The uterine artery originated from main trunk and anterior stem of abdominal aorta.Part of uterine artery originated from the perineum branches of gluteal artery,Other origins are rare.The uterine artery has an acute angular relationship with superior blood vessels,obtuse Angle relationship is rare.It is good for interventional therapy to choose intubation.2.The development of ovarian artery is closely related to age,the most common opening is anterior abdominal wall of the abdominal aorta,at first lumbar level,between the upper and lower edge of the vertebral body.3.The capillary network of uterine artery and ovarian artery can’t displayed clearly by CTA detection in current clinical application...
