Renal Artery Stenosis Evaluation

Patients were studied in the anterior, lateral decubitus, and prone position to visualize all portions of the renal artery. Renal duplex sonography was performed with Philips iU22G4 ultrasound system (USA) or GE Logiq E9 ultrasound system (USA). RAS was defined as stenosis with a focal renal artery peak systolic velocity exceeding 1.8 m/s in the main renal artery and defined as occlusion when an imaged renal artery lacked a doppler signal.20, 21, 22, 23

Renal Artery Stenosis Diagnosis

Check if the same lab product or an alternative is used in the 5 most similar protocols
Patients were studied in the anterior, lateral decubitus, and prone position to visualize all portions of the renal artery. Renal duplex sonography was performed with Philips iU22G4 ultrasound system (USA) or GE Logiq E9 ultrasound system (USA). RAS was defined by duplex scanning as having a renal aortic ratio of ≥3.5, a peak renal artery systolic velocity of ≥200 cm/s, or a renal artery occlusion. This criterion can discriminate ≥60% atherosclerotic RAS (ARAS) from <60% RAS accurately.[7 (link)]

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
