Zorluk: ZorMenstrual Cycle Abnormalities and Contraception

During a routine wellness visit, a 3838-year-old G2P2 patient expresses interest in resuming prescription birth control. She previously used an etonogestrel/ethinyl estradiol vaginal ring for several years without adverse effects, but discontinued it prior to her last pregnancy. She gave birth 88 months ago and is no longer breastfeeding. She hopes to attempt pregnancy again in approximately 1212 to 1818 months. Her menstrual cycles have resumed but are characterized by severe lower abdominal cramping and heavy bleeding lasting 88 days, requiring her to change pads every 22 hours. Medical history is notable for generalized anxiety disorder and tobacco use disorder; she consumes approximately 2020 cigarettes daily. Vital signs include a blood pressure of 146/92146/92 mmHg and a body mass index of 28 kg/m228 \text{ kg/m}^2. Pelvic examination is unremarkable, and a urine beta-hCG test is negative. She requests a new prescription for the vaginal ring. Which of the following is the most appropriate contraceptive management for this patient?

  1. A
    Prescription of the etonogestrel/ethinyl estradiol vaginal ring
  2. Insertion of a levonorgestrel-releasing intrauterine deviceCevap
  3. C
    Insertion of a copper-containing intrauterine device
  4. D
    Prescription of drospirenone/ethinyl estradiol oral tablets
  5. E
    Intramuscular injection of depot medroxyprogesterone acetate

Cevap

Insertion of a levonorgestrel-releasing intrauterine device is the most appropriate management.
The most appropriate management is the insertion of a levonorgestrel-releasing intrauterine device. This patient has an absolute contraindication to estrogen-containing contraceptives because she is over age 35 and smokes 15 or more cigarettes daily, placing her at an unacceptably high risk for cardiovascular events (WHO MEC Category 4). This rules out the vaginal ring and oral tablets. Furthermore, because she suffers from heavy menstrual bleeding and severe dysmenorrhea, a copper intrauterine device is contraindicated as it typically worsens these symptoms. The levonorgestrel-releasing system provides highly effective, reversible contraception without systemic estrogen. Its local release of progestin suppresses endometrial proliferation, making it a first-line treatment for her heavy menstrual bleeding, and it allows for a rapid return to fertility when she is ready to conceive.

Adım Adım Çözüm

1
Evaluate the patient's cardiovascular risk factors and current medical status.
The patient is 38 years old, smokes 20 cigarettes per day, and has stage 1 hypertension (BP 146/92 mmHg).
Identifying baseline risk factors is mandatory before prescribing any hormonal contraception to prevent severe vascular events.
2
Apply the World Health Organization Medical Eligibility Criteria (WHO MEC).
Age ≥\ge 35 years combined with smoking ≥\ge 15 cigarettes daily constitutes a Category 4 (absolute) contraindication for all estrogen-containing contraceptives.
Estrogen significantly increases the risk of arterial thrombosis (myocardial infarction and stroke), which synergizes dangerously with heavy smoking in older reproductive-age women.
3
Assess the patient's gynecologic and reproductive timeline requirements.
The patient suffers from severe dysmenorrhea and heavy menstrual bleeding, and she desires rapid return to fertility within 12 to 18 months.
The selected contraceptive must not only prevent pregnancy but also manage her abnormal uterine bleeding while accommodating her short-term fertility goals.
4
Select the optimal contraceptive method balancing all constraints.
The levonorgestrel-releasing intrauterine device is selected.
It contains no estrogen (safe for her cardiovascular profile), provides profound local thinning of the endometrium to treat heavy bleeding, and offers rapid return to fertility upon removal.

Anahtar Kavram

Women aged 35 years or older who smoke 15 or more cigarettes per day have an absolute contraindication to estrogen-containing contraceptives; levonorgestrel intrauterine devices provide safe contraception and treat concurrent heavy menstrual bleeding.
