Abstract

Objectives: To describe the clinical characteristics of patients with presternal keloids following cardiovascular surgery treated at the National Burn Hospital Le Huu Trac.


Methods: A retrospective descriptive study was conducted on 25 patients with presternal keloids after cardiovascular surgery who were treated between 2022 and 2025. Demographic data, medical history, and clinical characteristics were collected from medical records. Scar severity was assessed using the Japan Scar Workshop Scar Scale (JSS) and the Patient and Observer Scar Assessment Scale (POSAS).


Results: The mean age was 46.6 years; females accounted for 60% of patients, and 76% were older than 40 years. Coronary artery bypass surgery was the most common causative procedure (40%). Keloids developed at a mean of 7.3 months after surgery. The mean interval from keloid onset to the first specialized treatment was 175.2 months. Previous treatment had been performed in 64% of patients, all of whom experienced recurrence. The butterfly-shaped pattern was the most common morphology (32%). Mean scar dimensions were 14.5 × 3.4 × 0.8 cm. The mean JSS score was 18.1 ± 2.5, while the mean total POSAS scores assessed by observers and patients were 38.3 ± 4.5 and 40.1 ± 3.2, respectively.


Conclusion: Presternal keloids after cardiovascular surgery are characterized by large size, severe clinical manifestations, and a high recurrence rate. Early detection and timely intervention are important for improving treatment outcomes.
