Ultrasound in Assessment of Diabetic Macroangiopathy and Microangiopathy in Patients with Type 2 Diabetes Mellitus

Aim of the study was to assess Doppler parameters in renal and central retinal arteries in comparison with a common carotid artery intima-media characteristics using color and pulse wave Doppler. These parameters were studied in 100 patients with type 2 diabetes mellitus and in 20 healthy volunteers. Abnormal lamination and solitary hyperechoic elements within the vascular wall were presented as ultrasound features of the diabetic (metabolic) macroangiopathy. Ultrasound hallmarks of the diabetic microangiopathy in patients with type 2 diabetes mellitus were characterized by reduction of the blood flow velocities and increase of peripheral resistance indices in renal and central retinal arteries. Diabetic microangiopathy causes similar changes of the peripheral resistance indices in renal and central retinal arteries. Common carotid artery intima-media thickening is higher than peripheral resistance indices in renal and central retinal arteries increasing. Ultrasound signs of the diabetic macroangiopathy in common carotid artery have prognostic value for diabetic microangiopathy in renal and central retinal arteries.
