Abstract:

BACKGROUND: Deep vein thrombosis is a serious complication of total knee arthroplasty surgery, if patients are not promptly diagnosed and treated properly, the healing of the patient’s condition may be delayed, and even blood clots shedding causes pulmonary embolism, endangering the lives of patients. At present, no evidence has supported that total knee arthroplasty can increase postoperative deep venous thrombosis incidence in hypertensive patients.
OBJECTIVE: To observe whether hypertension would influence the occurrence of deep venous thrombosis in patients who underwent total knee arthroplasty.
METHODS: A retrospective analysis was performed among patients underwent total knee arthroplasty in Department of Joint Surgery, the First Affiliated Hospital of Xinjiang Medical University from September 2010 to March 2014. Patients were divided into hypertension group and control group based on their medical history of hypertension. Doppler ultrasonography was applied to detect both lower extremities among these patients after operation, to diagnose if there was any evidence of deep venous thrombosis. The incidence of deep venous thrombosis in the two groups was compared. The correlation of hypertension and deep venous thrombosis was analyzed.
RESULTS AND CONCLUSION: A total of 525 patients were involved in this study, including 219 in hypertension group and 306 in control group. Among them, 20 patients appeared deep venous thrombosis and the incidence rate was 3.8%. 13 patients in the hypertension group (2.5%) and 7 patients in the control group (1.3%) developed deep venous thrombosis. Chi-square test showed that, the risk of deep venous thrombosis in the hypertension group was 2.7 times of that in the control group, and the differences were statistically significant between the two groups (P < 0.05). Hypertensive patients suffer a higher incidence rate of deep venous thrombosis after total knee arthroplasty compared with those with normal blood pressure.
