Purpose
The management of hydatid disease (HD) co-occurring with pregnancy remains a challenge for physicians. We aimed to determine factors that were related to fetal and maternal outcomes in HD complicated pregnancies and then develop an approach/treatment algorithm.
Method
All patients at the participating hospitals were first analyzed to determine whether they had HD. Only patients diagnosed with HD during the course of their pregnancy were included. Certain cyst-related factors (diameter, localization, increase in size, and viability) and certain pregnancy-related factors (treatments, gestational week, maternal co-morbidities, and delivery type) were investigated. Nonlinear principal component analysis (NPCA) was performed to determine the relationships between the categories of variables.
Results
Out of 12,926 pregnancies, 27 cases were diagnosed with HD. In 13 cases, each developed at least one fetal problem. Using Albendazol in first trimester, presence of an active cyst, increased diameter by more than 1 cm during pregnancy and a cyst diagnosed in the second trimester were associated with at least one fetal problem. According to the NPCA results, cyst diameter when first diagnosed was related to fetal outcomes; a cyst greater than 10 cm was associated with “at least one fetal problem”. Cysts 5–10 cm in diameter were in a neutral position, while 2–5 cm in diameter were in the “no problems” group.
Conclusions
HD mostly affects fetus. If cyst-related and pregnancy-related variables are optimal, close follow-up on a monthly is the best course of action. However, in high-risk conditions, percutaneous interventions or surgery should be considered.
