====== 🧠 Postoperative Imaging After Ventricular Catheter Placement ====== ✅ 1. Non-Contrast [[Head CT]] (immediate post-op, within 24 hours) Purpose: Confirm catheter placement within the ventricular system. Evaluate for complications: ▸ Intracranial hemorrhage (intraventricular, intraparenchymal, subdural). ▸ Pneumocephalus. ▸ Malposition (e.g., catheter tip in brain parenchyma or outside ventricle). Assessment Criteria: Catheter tip ideally placed in the frontal horn of the lateral ventricle, near the foramen of Monro. Check midline shift, ventricular size, and pericatheter hemorrhage.
