Summary

Interstitial lung diseases (ILD) are common in clinical practices and need multidisciplinary assessment of clinical presentations, radiological and histological features. Transbronchial cryobiopsy (TBCB) is one of the most important invasive procedures for ILD when a confident diagnosis cannot be made by clinical and radiological assessment. TBCB could lead to higher incidence of risks. The pneumothorax and severe bleeding seemed to be more common in patients with TBCB.

Cone-beam computed tomography (CBCT) could provide 3-dimensinal (3D) CT images which were close to the image qualities of conventional CT. The probe-to-pleura relationship could be accurately established by the 3D CT scan and the cryobiopsy safety profile might be improved under the guidance of CBCT. In this study, we conducted a prospective study to observe the safety and diagnostic efficacy of CBCT guided TBCB for the DPLD patients.

Conditions

  • ILD

Interventions

PROCEDURE

cone beam CT guided transbronchial cryobiopsy

CBCT images are acquried and reviewed in axial, coronal and sagittal planes to most accurately assess the cryoprobe position within the lung parenchyma and relative to other thoracic structures. The minimum probe-to-pleura distance will be measured. If the position of cryoprobe is proper, TBCB will be perfomed.
