<FlashCard questions="8">
|q1= How do most twin pregnancies originate?
|a1= From multiple ovulations, i.e. dizygotic
|l1= Twin Pregnancies - Horses#Introduction
|q2= Why does twinning cause abortion?
|a2= An equine pregnancy requires the surface area of the entire uterus for placentation for one foal. If it is shared then it is inadequate to maintain a pregnancy.
|l2= Twin Pregnancies - Horses#Introduction
|q3= What happens if twin pregnancies implant in the same uterine horn?
|a3= 75% naturally reduce to a singleton, the other 25% will develop and most likely abort without intervention.
|l3= Twin Pregnancies - Horses#Introduction
|q4= What breeds conceive twins most commonly?
|a4=
*Thoroughbreds
*Draft horses
|l4= Twin Pregnancies - Horses#Signalment
|q5=When do horses with twin pregnancies usually abort?
|a5= In the third trimester: 7-9 months of gestation.
|l5= Twin Pregnancies - Horses#Clinical Signs
|q6= When should mares be scanned for twins?
|a6=
*13-15 days gestation
*Again before 30 days
|l6= Twin Pregnancies - Horses#Diagnosis
|q7= Why should mares be scanned before breeding?
|a7= To identify and map any endometrial cysts so that they do not confuse pregnancy diagnosis.
|l7= Twin Pregnancies - Horses#Diagnosis
|q8= What is the most common method of reduction of a twin?
|a8= Manual manipulation of one conceptus to the end of a uterine horn and pressure applied to crush the vesicle. This should be done prior to 30 days of gestation to secure the best chance for the remaining foetus.
|l8= Twin Pregnancies - Horses#Treatment
