Abstract:
From 1986 we have operated upon 13 patients with small neoplasms localised deep intracerebrally or subcortically in the central region with stereotactic guidance. Exact localisation of the tumour was one aim, whereas another one was to avoid damaging functionally important structures. In the first two patients we performed stereotactic marking of the tumour after craniotomy. The following procedure was found to be particularly useful: - determination of the tumour coordinates and planning of the approach - approach by means of a stereotactically guided probe, if necessary biopsy - stereotactically guided introduction of the leading catheter - removal of the stereotactic frame and bedding of the patient - craniotomy and microsurgical resection of the tumour This surgical procedure may be performed in one or two separate sessions. The accuracy of microsurgical tumour resection achieved by stereotactic means resulted in a remarkable reduction of postoperative neurological deficits.
Insights
Stereotactic guidance improves microsurgical resection of deep brain tumors, enhancing precision and minimizing postoperative neurological deficits in patients with small neoplasms.
Area of Science:
- Neurosurgery
- Stereotactic Surgery
- Oncology
Context:
- Management of deep intracerebral and subcortical neoplasms.
- Challenges in precisely localizing small tumors and preserving critical brain structures.
Purpose:
- To evaluate the efficacy of stereotactic guidance in microsurgical tumor resection.
- To assess the impact of stereotactic techniques on reducing postoperative neurological deficits.
Summary:
- A stereotactic-guided surgical procedure was developed for 13 patients with small, deep-seated brain tumors.
- The technique involves precise coordinate determination, stereotactic probe/catheter guidance, and subsequent microsurgical resection.
- This approach can be performed in one or two sessions, optimizing tumor removal and minimizing damage to surrounding brain tissue.
Impact:
- Demonstrated high accuracy in microsurgical tumor resection through stereotactic methods.
- Resulted in a significant reduction in postoperative neurological deficits for patients.
- Highlights the value of stereotactic guidance in neurosurgical oncology for improved patient outcomes.
