CT-gesteuerte schneid-saug-biopsie zur minimal invasiven histologischen abklarung pathologischer thoraxbefunde

Problem: An investigation into CT-controlled carve-suction biopsy for a histological clarification of indefinite intrathoracic masses. Materials and Method: 143 CT-controlled interventions were performed on 102 patients. For histological evaluation purposes, tissue was taken under application of the carva-suction biopsy method (16-18 gage). The lesions with a diameter of 5- 70 mm were located in the mediastinum (25%), were close to the thoracic wall/pleural (40%) and intrapulmonary (35%). Results: 92.2% (94/102) of the interventions provided histologically utilizable material in at least one biopsy specimen. The clinical suspected diagnosis was confirmed 78 times (76.5%), while a different disease was evident 16 times (15.7%). In 8 cases, a diagnosis was not possible (7.8%). The total complication rate was 21.6%. The following were observed: 18 pneumothoraxes, 2 hemothoraxes, and 2 patients who demonstrated a hemoptysis. In 4/102 patients (3.9%) complications arose which had to be treated therapeutically. Two-sided complications were not observed. Conclusions: The CT-controlled carve- suction biopsy can be employed histologically to clarify indefinite intrathoracic findings with a high degree of certainty and justifiable complication rates. In addition to this, the minimally invasive procedure helps to reduce costs.
