What are the contraindications for percutaneous biopsy?
There are no absolute contraindications for IPNB. Consideration of performance of a biopsy must be carefully weighed against the risks of the procedure. There are several relative contraindications, which in some cases may preclude the performance of a percutaneous biopsy. Relative contraindications for percutaneous needle biopsy include:
- • Coagulopathy that cannot be adequately corrected.
- • Hemodynamic instability or severely compromised cardiopulmonary function.
- • Patient inability to cooperate or to be adequately positioned for the procedure.
- • Lack of a safe pathway through tissues to the lesion.
- • Pregnancy (when image guidance requires exposure to ionizing radiation).
