Objective

Minor postoperative hemorrhage is a well known sequel after stereotactic brain biopsy. However, due to lack of symptoms it is diagnosed infrequently. This study was performed to evaluate occurrence and clinical impact of postoperative hemorrhage after image guided stereotactic biopsy.

Methods

160 patients with different brain lesions, 58 women and 102 men (mean age 62,5±14,8 years) underwent a stereotactic biopsy. All stereotactic biopsies were CT-guided and frame-based. Postoperative CT scans were obtained within 24 hours to identify the occurrence of postbiopsy hemorrhage. The following patient subgroups were analyzed : 1. High grade gliomas (n=80), 2. Lymphomas (n=25), 3. Low grade gliomas (n=8), 4. Metastases (n=6), 5. Intracranial infections (n=11), 6. Others (n=22). In 8 patients a diagnosis could not be obtained.

Results

In 37 (23,1%) of these patients, a minimal, dot-like hemorrhage in the biopsy area without clinical relevance occurred. In two patients a tiny additionally subarachnoid hemorrhage was seen. In one patient (0,6%) with a glioblastoma a clinically significant postoperative bleeding with intraventricular hemorrhage occurred. The hemorrhage rates in the different subgroups showed no significant differences.

Conclusions

After biopsy, minimal, dot-like hemorrhage is a frequent sequel but without impact on the clinical outcome. There are no high risk subgroups for the occurrence of minor hemorrhage after stereotactic biopsy.
