Trephine Biopsy for Diffuse Lung Lesions.

Trephine biopsy of the lung and pleura.

Percutaneous trephine biopsy of the lung.

Needle lung biopsy performed with a trephine cutting needle attached to a high speed pneumatic drill is a new technique which can be expected to yield a high quality lung specimen in 85 percent 90 percent of attempts. This technique is especially applicable to diffuse pulmonary disease. The most frequent complication is the development of pneumothorax (in up to 65 percent of biopsies) which if ...

trephine biopsy specimens

A technique for the extraction of cells from bone marrow trephine core biopsy specimens using collagenase digestion was assessed in 39 cases (33 diagnostic and six normal). Diagnostically useful numbers of cells were extracted from all marrows. Morphological assessment ofcytocentrifuge preparations of these cells gave a correct diagnosis in 23 (60%) of cases compared with 27 (70%) for the corre...

Open lung biopsy for diffuse interstitial lung disease in children.

The aim of the study was to investigate the contribution that open lung biopsy makes to the management of children with diffuse interstitial lung disease and to review the procedure-related morbidity in comparison with published literature on other biopsy techniques. The authors reviewed the case notes and histology of patients under 18 yrs who had had an open lung biopsy in 1991-1998 for inves...

Open lung biopsy for diffuse parenchymal lung disease in children.

An open lung biopsy was performed in 12 children with diffuse parenchymal lung disease. A definitive histopathological diagnosis was obtained from all procedures but determined treatment options in only 10 children (83%). Three (25%) children were ventilated for respiratory failure prior to the procedure. Four (44%) of the other 9 children required ventilatory support after the procedure. Three...
