Key result
Iliac artery blood flow measured by angiographic cinedensitometry was significantly lower in patients with peripheral vascular disease (166-506 ml/min) compared to normal controls (371-766 ml/min).
Why the study?
Does an improved angiographic cinedensitometric technique detect differences in iliac artery blood flow between patients with and without peripheral vascular disease?
Observational (n=35)
Does an improved angiographic cinedensitometric technique detect differences in iliac artery blood flow between patients with and without peripheral vascular disease?
An improved angiographic cinedensitometric technique can precisely measure iliac artery blood flow and detect significant reductions in patients with peripheral vascular disease.
Cinedensitometry quantifies iliac flow reductions in PVD; leaves open its diagnostic role pending prospective validation.
The blood flow of iliac arteries was measured by means of an improved angiographic cinedensitometric technique. This consists of cineradiographic recording of contrast injection into the iliac arteries, followed by optical analysis of the “washout” phase of the contrast material at selected sites. In 25 patients without peripheral vascular disease, undergoing abdominal angiography for different reasons, the blood flow measurements in left iliac arteries were within the limits of 371–766 ml/min. No age differences were noted but the blood flow in females were significantly lower than in males. In 10 patients with peripheral vascular diseases, the blood flow measurements varied from 166 to 506 ml/min. which is significantly lower compared to the “normal” controls. Precision of the technique was determined by “in vitro” measurements and was 5%.

Itzchak et al. (1975) conducted an observational in Peripheral vascular disease (n=35). Peripheral vascular disease vs. No peripheral vascular disease was evaluated on Blood flow in the iliac arteries. Iliac artery blood flow measured by angiographic cinedensitometry was significantly lower in patients with peripheral vascular disease (166-506 ml/min) compared to normal controls (371-766 ml/min).
