Objective:
To report a case of successful use of a transdermal contraceptive in a patient with hereditary angioedema.
Design:
Case report.
Setting:
University medical center.
Patient(S):
A patient who had used oral contraceptives contracted SC and submucosal tumefaction every 1 or 2 months. She was diagnosed with type I hereditary angioedema. It was determined that she was complement C4 deficient and C1-inhibitor quantitative deficient but functional C1-inhibitor normal. After she was diagnosed, the use of oral contraceptives was contraindicated.
Intervention(S):
Oral contraceptives were suspended, and a hormonal transdermal contraceptive was started.
Main Outcome Measure(S):
The absence of symptoms after 26 months using a transdermal contraceptive.
Result(S):
After 26 months of using this treatment, the patient has not experienced any symptoms of the hereditary angioedema.
Conclusion(S):
The use of hormonal contraceptives transdermally can be an alternative in patients with hereditary angioedema.
