Pratt Test
Pratt Test
The Pratt Test (pronounced: /præt tɛst/) is a medical procedure used to evaluate the competency of the venous valves in the superficial and deep veins of the legs. The test is named after the American surgeon, Dr. John Herbert Pratt, who first described the procedure in the early 20th century.
Etymology
The term "Pratt Test" is derived from the name of its inventor, Dr. John Herbert Pratt, an American surgeon who made significant contributions to the field of vascular surgery. The word "test" comes from the Old French test, meaning "an examination or trial".
Procedure
The Pratt Test is performed with the patient in a standing position. The examiner places one hand on the lower part of the patient's leg and the other hand on the upper part. The lower hand is used to occlude the veins while the upper hand is used to empty them by applying pressure. The lower hand is then released while the upper hand remains in place. If the veins fill rapidly from below, this indicates that the valves in the veins are incompetent.
