Diagnosis of ruptured breast implants through high-resolution ultrasound combined with real-time elastography.
Aesthetic Surgery Journal 2015 May
BACKGROUND: Implant rupture as a late complication of breast implant surgery is often a silent phenomenon that is difficult to diagnose. Sonoelastography is a new ultrasound-based technique that allows assessment of tissue elasticity.
OBJECTIVES: This study was undertaken to evaluate elastographic findings in normal and ruptured breast implants.
METHODS: This prospective study included 28 implants in 16 patients, all of whom underwent high-resolution ultrasound and real-time elastography. The diagnosis of implant rupture was confirmed by surgery.
RESULTS: Implant rupture was diagnosed in 5 out of 28 implants (17.9%). In those patients with ruptured implants, 3 had no symptoms, 1 presented with pain, and 1 complained of ipsilateral axillary lymph node swelling. Implants with a homogenous anechoic interior were considered to be intact. Ultrasound findings indicating implant rupture included multiple parallel echogenic lines in the implant interior in 2 cases and a mix of hyperechoic and hypoechoic masses in 3 cases. The feasibility of real-time elastography of implants was demonstrated in all cases. Elastograms of intact implants revealed a typical blue-green-red pattern familiar from cystic lesions. In all 5 ruptured implants, elastography revealed yellow-green figures without typical layering.
CONCLUSIONS: To the authors' knowledge this is the first series to combine high-resolution ultrasound with real-time elastography for the diagnosis of implant rupture. Since there are distinct differences between elastograms of intact and ruptured implants, addition of real-time elastography to conventional ultrasound may improve implant surveillance and obviate the need for magnetic resonance imaging.
