Ultrasound duplex scanning can provide additional information that may guide surgical decisions, in addition to arterial physiologic testing. The location and severity of arterial narrowing and occlusion can be identified using ultrasound duplex scanning.
The additional information from duplex scanning can help determine if arterial disease might be appropriately treated with a surgical procedure. The type of treatment and the technical approach can be guided by the duplex scan findings. Information from the ultrasound duplex scan can help patients be better informed about their options.
