Late unilateral hematoma after breast augmentation

Area of Science:

• Plastic Surgery
• Surgical Pathology
• Biomedical Engineering

Background:

• Late hematoma following breast augmentation is a rare complication with an unclear cause.
• This study investigates the etiology of late hematomas in patients with silicone gel implants.

Purpose of the Study:

• To analyze the clinical and histological features of late unilateral hematomas after cosmetic breast augmentation.
• To understand the pathophysiology of recurrent bleeding within the breast implant capsule.

Main Methods:

• Retrospective analysis of five patients with late unilateral hematoma after submuscular silicone gel implant placement.
• Explantation, capsulectomy, and comprehensive histological examination of all excised capsules were performed.

Main Results:

• Patients experienced progressive unilateral breast enlargement, doubling in size, 9-38 years post-augmentation without trauma.
• Histological analysis revealed recurrent hemorrhage within and on the capsule surface, with active bleeding up to 12 months post-initial event.
• Bleeding originated from medium-sized vessels within the capsule walls.

Conclusions:

• Late hematomas result from recurrent bleeding within the capsule, mimicking a chronic expanding hematoma.
• Progressive breast enlargement is a hallmark of this condition, developing over time.
• Complete capsulectomy is essential to address the source of bleeding and prevent recurrence.
