Radiological Comparison of Catheter Tip Position According to Two Entry Points (Occipito-Parietal and Keen's) in Patients with Hydrocephalus Undergoing V-P Shunt Surgery

Background: The ventriculo-peritoneal (VP) shunt operation is one of the most common neurosurgical practices for treatment of hydrocephalus. However, malfunction is one of the frequent complications due to improper placement of the ventricular catheter tip. Various entry points for external cranial ventricular access have been demonstrated to avoid this complication. Aim: To compare the post-operative radiological findings of ventricular catheter position between keen's and occipito-parietal point in patients having V-P shunt surgery. Methods & Material: A total of 56 admitted patients with 28 equal participants in two groups namely ‘Keen's point group’ and ‘Occipito-parietal point group’ who underwent VP shunt surgery through respective entry points. A post- operative CT scan of head was done for each patient for the assessment grading. Results: We observed that
