Extravascular Ultrasound Guidance for CTO Crossing

Extravascular Ultrasound Guidance for CTO Crossing

The use of ultrasound (US) to visualize vascular structures and interventional devices has been a great addition in the evaluation and treatment of patients with critical limb ischemia (CLI). In an effort to standardize the treatment of chronic total occlusions (CTOs), this article describes the stepwise approach and US-guided techniques utilized to access vascular conduits, place and orient devices (sheaths, wires, catheters, crossing tools, re-entry tools, atherectomy devices, balloons...
