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

Abstract

Objectives: This study aims to investigate the prevalence of venous and arterial diseases in asymptomatic patients undergoing total knee arthroplasty (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±51.8 years; range, 50 to 85 years) who underwent arterial and venous bilateral Doppler ultrasound examination between October 2017 and February 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 vascular pathologies 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 may carry vascular risks. These silent patients can be identified by simple non-invasive tests. Patients under risk are supposed to be consulted with vascular surgery before the operation and can be operated in the hospital setting where a vascular surgery unit is available. Recognizing the silent group with color Doppler ultrasound can be helpful and feasible in patients undergoing TKA to reduce complication rate and to take precautions.

Cerebrovascular Complications in Spinal Fusion Surgery: A Nationwide 8-year Follow-up Study in South Korea

“…This knowledge may help spine surgeons to better educate patients and caregivers and prevent future complications. Surgical procedures that involve the introduction of foreign materials into the body can increase the risk of postoperative thrombus formation and circulatory disorders (Atilla & Akdoğan, 2019; Fonnes et al, 2016; Taheriazam et al, 2018). For example, chronic hypertension, rather than short-term hypertension, is the most influential factor in the increasing prevalence of CVD.…”
