Relation Of Symptomatic Lower Extremity Peripheral Arterial Disease And Renal Artery Stenosis

Objective:To discuss the prevalence of renal artery stenosis in patients with symptomatic peripheral arterial disease (PAD), in order to improve detection rate of renal artery stenosis in patients of symptomatic PAD. Methods:Data of105patients of symptomatic PAD was retrospectively analyzed. An angiography was performed on peripheral artery and renal artery. Common cardiovascular atherosclerosis risk factors were registered and analyzed with variables associated with the coexist of renal artery stenosis and symptomatic PAD. Results:Prevalence of renal artery stenosis in patients with symptomatic PAD was20.00%(21/105). Sex, age, smoking history, diabetes mellitus, hypertension, myocardial infarction, body weight, body height, body mass index, white cell count, fibrinogen count, blood platelets count, mean platelet volume, blood lipids, calcium ion, phosphorous ion, calcium phosphorus ratio, uric acid, serum creatinine, clinical manifestation typing of PAD, and peripheral caliber-like arterial lesions were not significantly associated with renal artery stenosis (P>0.05). Value of estimated glomerular filtration rate was an independence risk factor for renal artery stenosis (P<0.05). Conclusion: For patients with symptomatic PAD, when peripheral artery angiography is needed, renal artery angiography must be explored, contributing to the early diagnosis of renal artery stenosis.
