Middle aortic coarctation (MAC), a variantof middle aortic syndrome, is a rare entity withonly ~200 cases described in the literature.It classically presents with early onset andrefractory hypertension, abdominal angina,and lower extremity claudication(1).A 30 years-old woman, Her systolic bloodpressure measures 180-200mm Hg and diastolicpressures measure 70mm Hg in both arms,lower extremity pressures are approximately70mm Hg. Her bilateral femoral pulses andpedal pulses are nonpalpable, but present onDoppler exam and CT-Angiography.We prepared diagnostic of CT-Angiographyand Aortography before operation. Wesuccessful operated abdominal aorticcoarctation by “Silver graft” Aortoaortic bypasson the middle aortic, left nephrectomy.She was discharged home on postoperativeday 7. Post operation is good. We werecontrolled CT-Angiography.

Since a human being was born, female reproductive organs, particularly the structure and function of the ovaries are constantly changing. The findings of overseas studies referred hereunder show that the ovarian follicular growth and atresia in young girls occur simultaneously, continuously and actively. The histopathology and ultrasound examination of the ovaries in girls were similar in principles. We found that ovarian maturation is influenced by hormonal stimulation, not only by age. In the most of the study, ovarian follicles were divided into two groups; as micro-cysts (<9mm) and macro-cysts (>9mm).
In every country, physical development of inhabitants shall be researched academically in every 5 to 10 years, comparing to geography, nature, weather conditions, culture, occupation and livelihood of local residents, in connection with the social and economic development of the country; urban and rural areas. In the studies regarding physical growth and development of Mongolian children’s body, structure and maturation of the ovaries in girls have not been determined. However, in 1996, Tuul M. studied ovarian measurements in Mongolian adults sampling organs from cadavers. Fundamental research determining the characteristic of ovarian structure and maturation in Mongolian girls and comparing results with an onset of puberty is needed to be developed.
