Background/Purpose:
Kommerell diverticulum (KD) in children with right aortic arch and aberrant left subclavian artery can be treated surgically via left subclavian artery (LSCA) translocation or aortopexy. These procedures remain controversial. We compared the outcomes of both procedures.
Methods:
This retrospective study included 48 patients who underwent LSCA translocation (n = 26) or aortopexy (n = 22). Lateral thoracotomy and sternotomy were performed in 38 and 10 patients with severe intracardiac malformations, respectively.
Results:
The median age of the aortopexy group was 10 months, median follow-up was 14 months, and mean length of hospitalization was 11.41 ± 6.8 days. The median age of the LSCA translocation group was 12 months, median follow-up was 22 months, and mean length of hospitalization was 14.96 ± 7.74 days. Two patients (LSCA translocation group) required secondary intubations and none suffered from recurrent laryngeal nerve injury or complications related to LSCA translocation. Breathing and swallowing symptoms were relieved in all patients. No additional thoracotomies due to respiratory symptoms were required.
Conclusions:
These two procedures relieve the pressure on the trachea and esophagus with similar short-term outcomes. The long-term outcomes are unknown. LSCA translocation may be the best strategy to prevent symptom recurrence and late complications in these patients.
Level Of Evidence:
Level III.
