Description
Objectives To evaluate ultrasound (US)-guided treatment of capsular contracture (CC) in patients with reconstructed/ augmented breast. Methods Twenty-five patients with grade IV CC were treated with peri-implant US-guided injection of triamcinolone acetonide. Before/after treatment, maximum capsular thickness (MCT) was measured by ultrasound and pain assessed with visual analogue score (pain-VAS). Patients with pain relief at 1 month were considered early responders (ERs). Another injection was performed in patients without pain relief at 1 month (late responders, LRs). Results One patient (treated with chemo-radiotherapy) experienced severe pain and local reaction after the second injection, requiring surgery. Twenty-four patients had baseline MCT of 1.8±0.3 mm and pain-VAS of 4.9±0.5, the baseline MCT of 19 ERs (1.7±0.2 mm) being significantly lower than that of 5 LRs (2.1±0.2 mm) (p=0.030). ERs had significantly reduced MCT and pain-VAS at one (1.1±0.3 mm; 1.5±0.5) and 6 months (1.1±0.2 mm; 0.9±0.7, respectively) (p< 0.001). At 1 month, LRs had a significantly reduced MCT (1.6±0.1 mm, p=0.042) but non-significantly changed pain- VAS (4.7±0.2); 5 months later, MCT reached 1.0±0.1 mm, pain-VAS reached 0.8±0.5 (p<0.044).
