Measurement of Revascularization Effect Using Near Infrared Spectroscopy in Below the Knee Arteries.

Background: Current methods evaluating tissue ischemia are based mainly on evaluating blood flow and not tissue perfusion. However, diabetes mainly affects small vessels and blood flow evaluation is insufficient. The aim of the trial was to evaluate the feasibility of NIRS in measuring perfusion changes during chronic total occlusion (CTO) revascularization in below the knee (BTK) arteries.

[Diagnosis of renal vascular disease].

The aim of the study was to assess the diagnostic value of gamma scintigraphy, duplex ultrasound scan, computer tomographic angiography (CTA) and renal arteriography in 77 patients with arterial hypertension, 3 with hematuria, 3 with chronic renal insufficiency and 3 with the difference in kidney size. The following kidney vascularization pathology was revealed: renal artery stenosis in 27, thrombosis of renal artery in 1, aneurysm of renal artery in 4, arteriovenous fistulae in 1, anomalies of renal arteries in 12, atherosclerotic deterioration of accessorial renal arteries in 13, tumor of suprarenal gland with arterial stenosis in 2 patients. Gamma scintigraphy and duplex ultrasound scan were positive in detecting vascular pathology in 93.
