Clinical characteristics of deep venous thrombosis of lower extremity in the elderly / 中华老年医学杂志

ABSTRACT

Objective To analyze the clinical characteristics of deep venous thrombosis (DVT) of lower extremity in the elderly.Methods One hundred and eighty elderly inpatients with DVT and one hundred and forty-four non-elderly DVT inpatients were recruited in the study.The prevalence situation, risk factors, complications and curative effect were analyzed.Rcsulls The prevalence of DVT in patients aged 60-69 years was the highest(50.5%), followed by the patients aged 70-79 years(40.5 %), The five major risk factors were post-operation (27.8 %), malignant tumor (15.0 %), traumatic fracture ( 7.8 %), sequelae of cerebrovascular disease (7.2 %) and long-term bedridden(5.0%).49.4% of the elderly had Cockett's syndrome, including 14.0% of them with common iliac vein (CIV) occlusion(n=6), 48.8% of them with >50% stenosis of the CIV (n= 21) and 37.2% of them with <50% stenosis (n= 16).In acute stage of DVT, the curative effect of thrombectomy was superior to that of thrombolysis, while there were no statistically significant differences in curative effect between the two methods in non-acute phase.The curative effect between elderly group and non-elderly group did not show significant difference.Conclusions The elderly are easy to suffer from DVT, and malignant tumor and sequelae of cerebrovascular disease are the risk factors for DVT in the elderly.The curative effect of thrombectomy is better than that of thrombolysis in elderly patients with acute DVT.
