Abstract

Background

This study aimed to evaluate the feasibility of contrast-enhanced ultrasound (CEUS) and CEUS-guided interventions in the diagnostics of MRI visible targeted US occult breast lesions.

Patients and methods

This retrospective study examined 10 females with 10 occult, MRI only detected breast lesions between July 2014 and April 2017. Targeted second look US followed by CEUS with 2.4 ml of SonoVue® were performed for all of the lesions. After positive CEUS localization the same dose was repeated for confirmation and CEUS-guided interventions were performed.

Results

MRI revealed 8 mass lesions with a mean size of 9 mm (range 5–16 mm) and 2 non-mass enhancing lesions of 10 and 20 mm in largest diameters. Targeted US revealed no morphological correlate for the lesions. Five out of 10 lesions (50%) were visible on CEUS. CEUS-guided core biopsy was performed on 4 lesions and 1 was marked with a clip for later surgical removal. Histopathological analysis confirmed 4 of them to be malignant. Three out of 5 nonvisible lesions on CEUS underwent MRI-guided interventions, 1 lesion was scheduled for follow-up as it was non-amenable for MRI biopsy, and 1 lesion was biopsied under US-guidance. Three of these nonvisible lesions on CEUS were confirmed to be malignant.

Conclusions

Based on our preliminary results, CEUS is a feasible tool for detecting many MRI only visible breast lesions, resulting in a more cost effective and less time-consuming practice. It is a more convenient alternative than MRI guided biopsy and has the potential to be included in the diagnostic algorithm which evaluates MRI only visible breast lesions.

Abstract

Background

Breast hematoma is an often underrated and disregarded post-procedural complication in the literature. Current treatment modalities are comprised of either surgical or expectant therapy, while percutaneous procedures play a smaller role in their treatment. We aimed to examine the efficacy of vacuum-assisted evacuation (VAE) in the treatment of clinically significant large breast hematomas as an alternative to surgery.

Patients and methods

We retrospectively analysed patients that underwent breast interventions (surgical and percutaneous), who later developed clinically significant large hematomas and underwent a trial of VAE of hematoma in our hospital within the period of four years. Patient and procedure characteristics were acquired before and after VAE. Success of intervention was based on ≥ 50% clearance of hematoma volume and patients’ subjective resolution of symptoms. All patients were followed clinically and by ultrasound if needed at different intervals depending on the severity of presenting symptoms.

Results

Eleven patients were included in the study. The mean largest diameter of hematomas was 7.9 cm and mean surface area was 32.4 cm2. The mean duration of the procedure was 40.5 min. In all patients VAE of hematoma was implemented successfully with no complications. Control visits showed no major residual hematoma or seroma formation.

Conclusions

Our results show that VAE of hematoma can be implemented as a safe alternative to surgery in large, clinically significant hematomas, regardless of aetiology or duration. The procedure carries less risk, stress and cost with the added benefit of outpatient treatment when compared to surgical treatment.
