Interventional embolization therapy of puerile congenital deep femoral arteriovenous fistula
This study aimed to investigate the treatment efficiency of interventional embolization therapy in puerile congenital deep femoral arteriovenous fistula. A retrospective analysis was conducted for 9 cases of congenital deep femoral arteriovenous fistulae treated in our department in the past 5 years. B-ultrasound examination indicated that all puerile patients suffered from deep femoral arterio...
متن کاملAmbiguous genitalia and intersex.
Intersex disorders are rare congenital malformations with over 80% being diagnosed with congenital adrenal hyperplasia (CAH). It can be challenging to determine the correct gender at birth and a detailed understanding of the embryology and anatomy is crucial. The birth of a child with intersex is a true emergency situation and an immediate transfer to a medical center familiar with the diagnosi...
متن کاملStatic allometry and animal genitalia.
A survey of 117 species of arthropods and 17 species of vertebrates showed a strong trend for male genitalia to have relatively low static allometric values. This trend contrasts with the allometry of other structures under sexual selection, which usually show steep allometric slopes. The trend to low allometric genital values is less consistent in mammals than in arthropods. Data not in accord...
متن کاملNormal Development of the Genitalia
For the purpose of this book, only a few aspects of genital development will be highlighted to facilitate understanding of the various disorders. A crucial point is that the external genitalia develop ‘automatically’ in the female direction unless there is testosterone activity in a critical period between 4 and 12 weeks of gestation. Furthermore, the Müllerian ducts develop into the uterus and...
متن کاملExperiments with genitalia: a commentary.
There has been a recent burst of studies of the function of genitalia, many of which share several important shortcomings. Given that further studies on this topic are likely (there are probably millions of species showing rapid genital divergence), I discuss the studies critically to promote clear formulation of hypotheses and interpretation of results in the future. I also emphasize some poss...
