Zorluk: OrtaMenstrual Cycle Abnormalities and Contraception

Seeking contraceptive counseling, a 25-year-old nulligravid woman presents to the gynecology clinic. She is in a monogamous relationship and desires to prevent pregnancy for at least the next five years. Her medical history is significant for Wilson disease, which is currently well-managed with trientine. She also reports a longstanding history of heavy menstrual bleeding that has previously required intermittent oral iron supplementation for mild anemia. Her current medications include trientine and a daily multivitamin. Vital signs are within normal limits, and her body mass index is 24 kg/m 2^2. A point-of-care urine pregnancy test is negative. The patient requests a highly effective, long-acting reversible contraceptive (LARC) method. Which of the following is the most appropriate recommendation for this patient?

  1. Levonorgestrel-releasing intrauterine deviceCevap
  2. B
    Copper intrauterine device
  3. C
    Etonogestrel subdermal implant
  4. D
    Combined oral contraceptive pill
  5. E
    Bilateral tubal ligation

Cevap

The most appropriate recommendation is the levonorgestrel-releasing intrauterine device.
The levonorgestrel-releasing intrauterine device (LNG-IUD) is the most appropriate choice for this patient. She explicitly requested a long-acting reversible contraceptive (LARC), narrowing the optimal choices to an IUD or a subdermal implant. The LNG-IUD provides highly effective contraception for 3 to 8 years (depending on the specific device). Furthermore, the local release of levonorgestrel induces endometrial atrophy, making it a first-line medical treatment for heavy menstrual bleeding. Unlike the copper IUD, it contains no copper and is completely safe in patients with Wilson disease.

Adım Adım Çözüm

1
Identify the patient's contraceptive preferences and timeline.
The patient desires a highly effective, long-acting reversible contraceptive (LARC) for at least 5 years.
This rules out short-acting methods like oral contraceptives and irreversible methods like tubal ligation.
2
Evaluate medical contraindications based on the patient's history.
The patient has Wilson disease, which is an absolute contraindication to the copper IUD.
Wilson disease causes toxic copper accumulation; adding a copper-containing device exacerbates the condition.
3
Optimize the choice based on the patient's gynecologic history.
The patient has baseline heavy menstrual bleeding causing mild anemia.
The levonorgestrel-releasing IUD thins the endometrium and significantly reduces menstrual blood loss, whereas the etonogestrel implant often causes unpredictable, prolonged bleeding.

Anahtar Kavram

The levonorgestrel-releasing intrauterine device is a first-line long-acting reversible contraceptive that also treats heavy menstrual bleeding, whereas the copper intrauterine device is absolutely contraindicated in patients with Wilson disease.
