A standard computed tomography (CT)-guided biopsy, aspiration, injection, or drainage procedure typically requires a direct line of access from the skin to the target lesion or collection. Safe performance of these procedures is ideally done without violation of vascular structures or solid or hollow viscous. When a direct pathway to the target is absent, patients are commonly denied the procedure and instead referred to surgery. This chapter describes a solution for CT-guided procedures when a direct line of access to the intended target is unavailable. The technique involves a coaxial needle system with simple modification (curving) of the inner needle.
