The prevalence of arterial and venous abnormalities in asymptomatic patients undergoing total knee arthroplasty

Özet

Objectives: This study aims to investigate the prevalence of venous and arterial diseases in asymptomatic patients undergoing total kneearthroplasty (TKA) and to evaluate possible surgery-related vascular complications.Patients and methods: The data of a total of 96 extremities of 48 vascular asymptomatic patients (9 males, 39 females; mean age 65.7±51.8years; range, 50 to 85 years) who underwent arterial and venous bilateral Doppler ultrasound examination between October 2017 andFebruary 2018 were retrospectively analyzed. Stenosis of the arterial and venous system thrombosis and venous insufficiency were recorded.Results: Although no significant vascular pathologies such as deep vein thrombosis or arterial occlusion were detected, minor vascularpathologies such as minimal atherosclerosis (29.2%) and venous reflux (25%) were found in patients scheduled for TKA.Conclusion: In most patients, TKA operations can be performed without a vascular comorbidity; however, even asymptomatic patients maycarry vascular risks. These silent patients can be identified by simple non-invasive tests. Patients under risk are supposed to be consultedwith vascular surgery before the operation and can be operated in the hospital setting where a vascular surgery unit is available. Recognizingthe silent group with color Doppler ultrasound can be helpful and feasible in patients undergoing TKA to reduce complication rate and totake precautions.
