Siemens Medical Solutions USA, Inc.: ACUSON Redwood 2.0 Ultrasound Systems Recalled for Measurement Errors

Agency Publication Date: September 13, 2023

Sign in to monitor this recall

Summary

Siemens Medical Solutions USA, Inc. has recalled 796 units of the ACUSON Redwood 2.0 ultrasound system because of a software-related measurement defect. When using an 18L6 transducer with settings originally created on an older 1.0 system, the newer 2.0 system may display measurements that are smaller than they actually are while in 'Dual format' view. This defect could cause healthcare providers to misinterpret ultrasound results, leading to a wrong diagnosis or incorrect medical treatment for a patient. These systems are identified by software versions starting with 'VA20' and were distributed worldwide, including 28 U.S. states and territories.

Risk

The software error causes the ultrasound system to underestimate measurements during clinical exams. This inaccuracy can lead to serious medical errors, such as miscalculating the size of a lesion or organ, which may result in delayed or inappropriate patient management decisions.

What You Should Do

  1. Identify if your facility uses the ACUSON Redwood 2.0 ultrasound system (Reference number 11503314) with a software version prefix starting with VA20.
  2. Check if you are using an 18L6 transducer with user-generated presets that were originally created on an older 1.0 version ultrasound system.
  3. Immediately stop using 1.0-version presets for the 18L6 transducer when viewing in the Dual format visualization function on any 2.0 system.
  4. Contact Siemens Medical Solutions USA, Inc. to determine if a software update or a specific configuration fix is required for your equipment.
  5. Consult with your healthcare provider or the manufacturer to review any past diagnoses made using these specific presets if an underestimation of measurements is suspected.
  6. Contact the FDA for additional questions at 1-888-463-6332 or visit www.fda.gov/medical-devices/medical-device-recalls.
