Stereotactic biopsy procedures for brain tumor diagnosis.

Stereotactic biopsy procedures, in which a computer-based, three-dimensional-image-guided system accurately locates patients' brain tumors, are relatively new diagnostic methods. Complications from stereotactic biopsy procedures are minimal compared with open craniotomy procedures because they are performed with local anesthesia. Perioperative nurses should have knowledge of and be trained in stereotactic biopsy procedures to ensure optimal care for patients undergoing these procedures.
