CT-guided and computer assisted stereotactic biopsy. Technique, results, indications

Area of Science:

• Neurosurgery
• Medical Imaging
• Pathology

Background:

• Stereotactic neurosurgery enables precise targeting of intracranial structures.
• Advancements in imaging and computer technology have enhanced stereotactic procedures.
• Accurate tissue diagnosis is crucial for effective treatment of intracerebral lesions.

Purpose of the Study:

• To present the development and clinical experience of a CT-guided computer-assisted stereotactic system.
• To evaluate the diagnostic accuracy and safety of image-guided stereotaxy for intracerebral lesions.
• To assess the complication rates associated with stereotactic interventions.

Main Methods:

• Development of a 3D localization and treatment planning system based on the Riechert-Mundinger stereotactic device.
• Application of CT-guided computer-assisted stereotaxy in 338 patients with various intracerebral lesions.
• Use of a 20 MHz Doppler probe on the cannula tip in 54 patients and histological comparison in 35 patients.

Main Results:

• The stereotactic system was applied to 338 patients for assessing intracerebral lesions.
• Histological diagnosis accuracy reached 88% when comparing stereotactic biopsies with post-resection or autopsy tissues.
• Complications included bleeding in 2.4% of patients (0.6% mortality) and 1.2% morbidity.

Conclusions:

• CT-guided computer-assisted stereotaxy is an effective and relatively safe method for diagnosing intracerebral lesions.
• The developed system demonstrates high diagnostic accuracy for histological examination.
• The low complication and mortality rates support the utility of this stereotactic approach.
