RESUMO
Objective To explore the instruction value of the color Doppler ultrasonography for the diagnosis and treatment of the pediatric intussusceptions .Methods Retrospective study the color Doppler ultrasonographic performance of 114 patients with diagnosis of pediatric intussusception in the affiliated hospital of Zunyi medical college ,from October 2009 to June 2012 ,reviewed the case ,groups were compared according to the ways of therapeutic methods .Results All the 114 cases of children of the intus-susception are subject to air enema reset or surgery cured confirmed .Age younger than 12 months intussusception children ,air ene-ma reset were more likely to success ;the diameter of concentric circles levy,the length of sleeve for and the thickness of bowel wall were smaller ,the more suitable for outsiders air enema reset .The blood supply of scabbard of bowel wall and the mesenteric was rich ,the air enema reset had a higher success rate ,blood supply was poor and the success rate was lower .The success rate of air enema reset was influenced by the part of intussusception .Conclusion Combined use of conventional color ultrasonic and high fre-quency probe checking ,can raise the diagnosis rate of pediatric intussusception ,the primary lesion confirmed and the detection rate in the position of the disease ,provide guidance for clinical choice reduction treatment .
RESUMO
Objective To observe the relationship between morphological and hemodynamic changes of female internal genital organs in the patients with hypomenorrhea with transvaginal color Doppler ultrasound (TVCDS). Methods Thirty female patients with hypomenorrhea of unknown origin were studied, and 30 healthy women of eumenorrhea aged 20 to 40 years were selected as control group. The size and shape of uterus, ovaries, and the thickness of endometria of uterus were observed with TVCDS in follicular phase, ovulation phase, luteal phase and luteal atrophy phase, respectively. Hemodynamic parameters of ovarian artery, uterus artery and their branches were measured. At the same time, hormones of female were examined in 30 patients in follicular phase, ovulation phase and luteal atrophy phase, respectively. Results ①No difference of the size of uterus and ovaries, the thickness of endometria and the amount of egg follicles was found between two groups (P＞0.05). ②Compared with that in the control group, type C of endometria increased in hypomenorrhea group (P＜0.05). ③RI, PI and S/D of spiral arteries in hypomenorrhea group were higher than those in control group, but no significance in these parameters of uterine arteries, arcuate arteries and radiate arteries was found. RI of uterine arteries, arcuate arteries and radiate arteries decreased successively. ④RI, PI and S/D of ovarian arteries in hypomenorrhea group was higher than those in control group in ovulation phase (P＜0.05). Conclusion Reduction in blood supply of ovary and endometria may be the causes of hypomenorrhea with unknown origin. TVCDS can be used as a conventional examination method for these patients.
