Internal Mammary Artery Compression After Pectus Excavatum Repair Does Not Increase Risk of Hemorrhagic Complications in Pediatric Patients

Objectives: Minimal invasive repair of pectus excavatum (MIRPE) described by Nuss is the most popular correction nowadays this deformity. During introduction bars, they can hurt or compress internal mammary arteries (IMA). The aim study was to observe prevalence IMA compression in children after MIRPE. Also, we examined if obstruction increases risk complications at bar removal, and these vascular changes are reversible. Materials Methods: All patients operated on our tertiary pediatric surgical center between 2013 2019 were involved study. Data age, sex, number bars characteristics deformity examined. flow checked Doppler ultrasound (DUS) MIRPE too. Results: Among 41 with mean age 15.2 years there 18 asymmetrical deformities, 23 sternal rotations. Mean index 4.01. After procedure 7(9%) stenoses 10(12%) occlusions found DUS. removal 3 4 have resolved, but all (3/3) persisted. There no during removals. Conclusion: uncommon, not influenced severity Obstruction vessels does increase hemorrhagic removal. larger cohort needed determine reversibility changes.
