CT guided stereotactic surgery : an overview of 600 procedures

Area of Science:

• Neurosurgery
• Radiology
• Medical Technology

Background:

• CT-guided stereotaxy is an advanced neurosurgical technique.
• The Brown Roberts Wells (BRW) system is utilized for precise localization.

Purpose of the Study:

• To present institutional experience with CT-guided stereotactic procedures.
• Document the types of procedures performed and their outcomes.
• Evaluate the safety and efficacy of stereotactic surgery.

Main Methods:

• Retrospective review of 600 CT-guided stereotactic procedures over 5.5 years.
• Procedures categorized into diagnostic biopsies, aspirations, functional procedures, and stereotactic craniotomies.
• Analysis of diagnostic accuracy, complication rates, and overall success.

Main Results:

• 600 procedures performed: 431 diagnostic biopsies, 52 aspirations, 13 functional, 104 craniotomies.
• Diagnostic yield for biopsies was 93.5% (28/431 non-diagnostic).
• Mortality rate was 0.41% (2/483), major morbidity 1.44% (7/483), and transient worsening 2.48% (12/483).
• Overall success rate in achieving preoperative objectives was 94% (564/600).

Conclusions:

• CT-guided stereotactic surgery offers a safe and effective approach for intracranial lesion management.
• The procedure has a low mortality and morbidity profile.
• It plays a significant role in neurosurgical interventions, particularly for lesions in eloquent areas.
