RESUMO
Mammography, ultrasound, and magnetic resonance imaging (MRI) are the most commonly used modalities for interventional radiology procedures involving the breast. Computed tomography (CT) is rarely used for breast imaging yet it is able to detect breast lesions and can often provide safe and effective access to breast lesions. The aim of this study was to demonstrate situations in which CT should be considered as an alternative guidance method for the biopsy of breast lesions that are not accessible with conventional imaging modalities.

OBJECTIVE: To evaluate the performance of computed tomography (CT)-guided percutaneous biopsy of abdominal lesions. MATERIALS AND METHODS: This retrospective, single-center study evaluated patients submitted to CT-guided percutaneous biopsy of abdominal lesions at a cancer center, between January 2014 and June 2015. The images and patient medical records were reviewed using a standardized data collection form. RESULTS: We included 225 procedures performed in 212 patients, of whom 143 (63.5%) had a prior diagnosis of cancer. Of the 225 lesions biopsied, 88 (39.1%) had a suspected primary origin and 137 (60.9%) were suspected metastatic lesions. Complications occurred in only 14 (6.2%), the most common being self-limited bleeding, which occurred in 12 (85.7%) of the 14. The occurrence of complications was not found to be significantly associated with the lesion location, age of the patient, presence of comorbidities, use of a supplementary technique, vascularization pattern, or proximity of the lesion to large vessels. The pathology findings were sufficient for making the diagnosis in 202 cases (89.8%), and the diagnosis was consistent with the clinical suspicion in 132 (58.6%). CONCLUSION: The procedure demonstrated a high (approximately 90%) rate of providing a sufficient sample for the diagnosis and a low complication rate, the most common complication being self-limiting bleeding.

Resumo Objetivo: Avaliar a performance das biópsias percutâneas de lesões abdominais guiadas por tomografia computadorizada (TC). Materiais e Métodos: Estudo retrospectivo, unicêntrico, com pacientes submetidos a biópsias percutâneas de lesões abdominais guiadas por TC em um centro de referência oncológico, no período de janeiro de 2014 a junho de 2015. Foram avaliados as imagens dos procedimentos e os prontuários dos pacientes, sendo preenchida uma ficha de coleta de dados padronizada. Resultados: Foram incluídos 225 procedimentos em 212 pacientes, dos quais 143 (63,5%) tinham história prévia de câncer. Das lesões submetidas a biópsia, 88 (39,1%) apresentavam suspeita de lesão primária e 137 (60,9%), de lesão metastática. Apenas 14 (6,2%) lesões evoluíram com alguma complicação, sendo a mais comum o sangramento autolimitado (n = 12; 85,7%). Todos os procedimentos foram realizados com técnica coaxial. Não houve diferença na incidência de complicações em relação a localização da lesão, idade, comorbidades, técnica utilizada, padrão de vascularização e proximidade de grandes vasos. O resultado do exame patológico foi suficiente para o diagnóstico em 89,8% (202) do total. O diagnóstico foi concordante com a suspeita em 58,6% dos casos. Conclusão: Os resultados demonstraram um índice de amostra suficiente para o diagnóstico de aproximadamente 90%, com uma taxa de complicação pequena, sendo a mais frequente o sangramento autolimitado.
