Ultrasound-guided radial vein cannulation for general anesthesia in cases with difficult peripheral venous access: a report of two cases.

Background: Despite advancements in ultrasonography, locating peripheral veins for catheter placement remains a challenge in patients with altered anatomy owing to multiple surgeries. Herein, we highlight the potential of using the radial vein as an alternative site for ultrasound-guided peripheral venous catheterization.

Case Presentation: We present two cases of patients with extensive surgical histories, including multiple abdominal surgeries, leading to difficult peripheral venous access.
