“…They considered this as a reflection of decreased perfusion in the microvascular space at the venous level. 16,17 In addition to these findings, in our study, we proved that the correlation of arterial and venous flow rate is impaired at the calf level rather than the thigh level in smokers with PAD. We also found a decrease in CFA, PV and PTA diameters in smokers.…”

“…Because, the venous FV value relies on the measurement of returning blood flow from the microvascular area that can originate from multiple sources, such as the main artery or collateral vessels, or be redistributed from other limb tissues and non-nutritive pathways. [14][15][16][17] In this study, we hypothesized that cigarette smoking has a reducing effect on the diameter, velocity and FV rates of crural vessels, potentially giving rise to impaired tissue perfusion. Venous FV values lower than homonymous arterial FV may be an indicator of impaired tissue perfusion in smokers.…”

“…Therefore, our aim is to show the decreased tissue perfusion in smokers with FV measurement, which is a reliable quantitative method. 16,17 To the best of our knowledge, no previous study has measured FV rates of lower extremity veins to predict tissue perfusion in smokers with PAD.…”

Aims: The purpose of this study was comparing flow volume rates, velocities and diameters of lower extremity arteries and veins of smokers and non-smokers with peripheral arterial disease. Patients and methods: The study consisted of 58 patients, 26 smokers and 32 non-smokers, who had no smoked for at least 5 years prior to the investigation. Colour Duplex Ultrasonography measurements of the common femoral artery, common femoral vein, popliteal artery, popliteal vein, anterior tibial artery, anterior tibial vein, posterior tibial artery and posterior tibial vein were obtained in the supine position. Differences in the diameters, blood flow velocities, and flow volume rates of the vessels were compared according to the sex, age and Colour Duplex Ultrasonography measurements of the patients. Results: The diameters of the common femoral artery, popliteal vein and posterior tibial artery were statistically significantly reduced in smokers. The flow volume rate of the popliteal artery showed a significant correlation with that of crural vessels in non-smokers but not in smokers. Conclusions: The absence of a statistically significant correlation between the measurements of the popliteal artery and crural vessels in smokers shows that cigarette smoking reduces the diameters and flow volumes of crural vessels, potentially giving rise to impaired tissue perfusion.

Angioarchitecture and hemodynamics of microvascular arterio-venous malformations

IntroductionArteriovenous malformations (AVMs) are characterized by pathological high flow, low resistance connections between arteries and veins. Treatment is critically dependent on correct interpretation of angioarchitectural features. However, some microfistular AVMs do not match the characteristics described in current AVM classification systems. Therefore, we propose a new subgroup of microfistular AVMs, composed of enlarged, fistulous paths on the venous half of capillaries and/or dilated draining venules (hyperdynamic, capillary-venulous malformation [CV-AVM]). CV-AVMs still ensure arterial flow to the periphery and fistulous venous drainage is less pronounced than in classical AVMs such that these lesions are often misinterpreted as venous malformations.Materials and methodsWe developed a computational model to study the effects of microvascular anomalies on local hemodynamics, as well as their impact on angiographic contrast propagation. Flow rates and pressures were computed with a lumped parameter description, while contrast propagation was determined by solving the 1D advection-diffusion equation.Results and conclusionsFor the newly proposed CV-AVM angioarchitecture, the computational model predicts increased arterio-venous contrast agent transit times and highly dispersive transport characteristics, compared to microfistular, interstitial type IV AVMs and high flow type II and III AVMs. We related these findings to time-contrast intensity curves sampled from clinical angiographies and found that there is strong evidence for the existence of CV-AVM.
