Ecografía Reproductiva y Gestacional.

Summary

The video discusses reproductive and Gestational Ultrasound in animals, focusing on the male and female reproductive systems, as well as the assessment of fetal development during pregnancy. Key scientific concepts and methodologies presented include:

Male Reproductive System

• Prostate Evaluation:
  • Ideal for all dogs and cats.
  • Should be symmetrical, homogeneous, and slightly hyperechoic or isoechoic.
  • Common pathologies:
    • Benign prostatic hyperplasia (enlarged prostate).
    • Prostatitis (infection).
    • Neoplasias (tumors).
    • Cysts and atrophy in neutered males.
• Testicular Evaluation:
  • Testes are located in the scrotum, separated by a septum.
  • Common pathologies:
    • Testicular neoplasias (15% of tumors in older dogs).
    • Cryptorchidism (undescended testicles).
    • Orchitis (infection).
    • Epididymitis (inflammation of the epididymis).

Female Reproductive System

• Anatomy and Evaluation:
  • Ovaries, uterine horns, and uterine body can be assessed via ultrasound.
  • Changes in size and appearance during the estrous cycle.
  • Common pathologies:
    • Polycystic Ovaries.
    • Endometritis (bacterial contamination).
    • Cystic endometrial hyperplasia (thickening of the uterine wall).
    • Biometra (pathological internal collection).

Gestational Ultrasound

• Fetal Assessment:
  • Vitality assessed by observing heart rate (normal: 230 beats/min for dogs, 228 for cats).
  • Count of fetuses ideally performed between days 28 and 35 of gestation.
  • Measurement methodologies:
    • For fetuses < 40 days: diameter of the internal sac.
    • For fetuses > 40 days: biparietal diameter of the head.
  • Suggested follow-up ultrasounds around days 35-40 for counting and 57 for development assessment.

Important Measurements and Formulas

• Formulas for estimating gestational age based on fetal measurements.
• Adjustments for different dog sizes (adding/subtracting days based on weight).
