IJV catheterization is a medical procedure involving the insertion of a catheter into the internal jugular vein (IJV) to gain central venous access. This technique is commonly employed for various purposes, including:

• Hemodynamic Monitoring: To assess and manage the cardiovascular status of critically ill patients.
• Administration of Treatments: Allows long-term delivery of fluids, antibiotics, medications, and nutritional support.
• Hemodialysis: Provides access for renal replacement therapy in patients with kidney failure.
• The IJV is a major vein that runs along the side of the neck and merges with the subclavian vein to form the brachiocephalic vein. The catheterization procedure is typically performed on the right side of the neck due to anatomical advantages, but the left side can also be used when necessary.
