Spontaneous pneumothoraces during pregnancy in patients with lymphangioleiomyomatosis.
CHEST(2023)
摘要
Patients with lymphangioleiomyomatosis (LAM) are prone to developing spontaneous pneumothoraces (SPs). We aimed to characterize the burden of SPs during pregnancy in LAM, using a web-based survey. Among the 50 respondents, 12 (24%) had never been pregnant and 38 (76%) were pregnant at least once, resulting in a total of 80 pregnancies. Respiratory symptoms during pregnancy led to the diagnosis of LAM in 34% of (13/38) patients, with SPs being the presenting manifestation in most of these patients (10/13, 77%). Eleven of the 38 pregnant patients (29%) experienced at least one SP during pregnancy. The majority of the SPs (∼60%) occurred during the second trimester. Our study provides valuable insights regarding the risk, burden, and timing of pregnancy-related SPs in patients with LAM that would be useful for the LAM community.
