目的:利用数字化三维重建技术重建盆腔血管及子宫,探讨卵巢动脉的分布、走形,并比较其在正常人、卵巢早衰患者和卵巢肿瘤患者中的血供差异,探索其在卵巢早衰诊疗中的应用前景。方法:收集9例正常人、7例卵巢早衰患者、11例卵巢肿瘤者的盆腔64排螺旋CT扫描数据,应用旭东数字医学三维可视化技术对其基于CT血管造影(CTA)扫描数据进行三维重建,比较3组卵巢动脉的血供差异。结果:1 9例正常人的盆腔血管三维重建结果中,盆腔血管形态规则、清晰,血管饱满光滑,子宫血供丰富,盆腔各级动脉分支显示较清楚。其中有6例可清晰地辨别出子宫动脉上行支以及与卵巢动脉的吻合支,正常人子宫动脉血管网血流丰富,子宫动脉的起始和分支走形均较卵巢早衰的患者好辨认。2 7例卵巢早衰患者的盆腔血管三维重建结果中,子宫动脉供血附件的属支细小、杂乱,难以辨别,从肾动脉水平未见卵巢动脉从腹主动脉或肾动脉发出。3 11例卵巢肿瘤患者的盆腔血管三维重建结果中,可见盆腔血流丰富,卵巢周围的动脉明显增粗,并与子宫动脉的吻合支交错复杂,其中6例卵巢癌患者的模型中卵巢血供极其丰富。结论:卵巢早衰患者的卵巢血供较正常人减少,卵巢肿瘤患者的卵巢血供则增多,卵巢早衰患者因卵巢动脉直径更加纤细,基于CTA数据的重建率较正常人低,而卵巢肿瘤患者因肿瘤血供丰富,卵巢供血血管重建率高于正常人。
OBJECTIVE: To reconstruct pelvic vessels and uterus by using digital three-dimensional reconstruction technique to explore the distribution and shape of ovarian artery and to compare the blood supply in normal, premature ovarian failure patients and ovarian cancer patients and to explore its role in the diagnosis and treatment of premature ovarian failure Application prospects. Methods: Pelvic 64-slice spiral CT scan data of nine normal subjects, seven patients with premature ovarian failure, and 11 patients with ovarian tumors were collected. Three-dimensional reconstruction based on CT angiography (CTA) scan data was performed using Xudong digital three-dimensional visualization technique , To compare the blood supply of 3 groups of ovarian artery. Results: The results of pelvic vascular reconstruction in 19 normal subjects showed that the vessels in pelvic vessels were regular and clear, the blood vessels were full and smooth, the uterus was rich in blood supply, and the branches of arteries in all pelvic stages were clearly shown. Among them, 6 cases can clearly identify the uterine artery ascending branch and anastomosis with the ovarian artery, the normal uterine artery blood flow network rich in uterine artery, the beginning and branch shape are better than those in patients with premature ovarian failure identified. Of the 27 cases of premature ovarian failure with pelvic vascular three-dimensional reconstruction results, uterine artery blood supply attachment is small, messy, difficult to distinguish from the level of renal artery no ovarian artery from the abdominal aorta or renal artery issued. In the pelvic vessel three-dimensional reconstruction results of 31 patients with ovarian tumors, the pelvic blood flow was abundant, the arteries around the ovary were significantly thicker, and the anastomosis with the uterine artery was staggered. Among the 6 ovarian cancer models, ovarian blood supply Extremely rich. Conclusion: Ovarian blood supply in patients with premature ovarian failure is lower than that in normal people. Ovarian blood supply to ovarian cancer patients is increased. Premature ovarian failure is more slender due to ovarian artery diameter. The reconstruction rate based on CTA data is lower than that in normal people. Rich tumor blood supply, blood supply to the ovary vascular reconstruction rate higher than normal.
