Significance of the measurement of PWV/ABI in lumbar spinal canal stenosis

Abstract

For 200 examples diagnosed with lumbar spinal canal stenosis (LSCS) at outpatient in Intermittent claudication (IC), PWV and ABPI were measured with a blood pressure pulse wave inspection device. Subjects consisted of 89 males and 111 females with an average age of 71.7 years old. Seven PWV cases and 6 ABPI cases could not be measured. Artery confinement could be heard in 15 cases (7.5%) and 165 cases of PWV were 1400 or above the standard value, while 9 cases (4.5%) had an ABPI of and less than 0.9. Six subjects could not be measured. Even orthopedic surgeons should always take blood vessel characteristics and mental change caused by chronic artery confinement into consideration in patients presenting with IC. When 0.91-0.99 was used as a border domain, cases increased to 38 examples (16%), but with a measurement of less than 1.0, 6 out of 32 cases could not be measured.
