Idiopathic Subglottic Stenosis During Pregnancy: Successful Treatment With Green Laser Ablation and Steroid Injection.

Idiopathic subglottic stenosis (ISGS) during pregnancy is extremely rare, with treatment strategies primarily based on a limited number of case reports. The most common management approach in pregnant women is therapeutic endoscopic treatment with a balloon catheter. This intervention is crucial for the well-being of both the mother and fetus and requires a multidisciplinary team, including specialists in obstetrics, anesthesiology, and otolaryngology. We present the case of a 31-year-old woman with ISGS at 28 weeks of pregnancy. Throughout the procedure, obstetricians performed fetal monitoring, while anesthesiologists managed her respiration and pain. The patient was successfully treated with laser ablation and steroid injection using flexible endoscopy under local anesthesia. She subsequently had a spontaneous vaginal delivery at 38 weeks and three days, giving birth to a healthy boy. This case highlights the successful management of symptomatic subglottic stenosis during pregnancy through endoscopic laser ablation and localized steroid injection.
