Abstract

Steady flows and pulsatile flows of a Newtonian fluid through a channel with a rectangular hump were numerically studied as a two-dimensional model of blood flow in a constricted artery. From the numerical calculation, it was shown that one of the hydrodynamic causes of endothelial lesion of artery and post-stenotic dilatation can be found in the large temporal variation of shear stress behind a constricted portion of artery. Local maximum of the pressure there can be seen as secondary factor for the post-stenotic dilatation.

Mixed multivariate generalized linear models for assessing lower-limb arterial stenoses.

Experiments and observational studies often involve gathering information on several response variables, enabling us to model their dependence on observable predictor variables. Despite associations between the response variables, they are often analysed separately using general and generalized linear models. This paper investigates applications of multivariate regression analysis to improve the accuracy of predictions and decisions, in the specific context of diagnosing arterial stenoses in human legs. Two basic models are developed for this application, using (i) four binary responses and (ii) a mixture of two binary and two normal responses. The results clearly demonstrate the potential advantages offered by this approach.

Stent-supported recanalization of chronic iliac artery occlusions.

PURPOSE: Iliac artery occlusions that are more than a few centimeters in length are normally treated with surgical bypass grafting. The aim of this study was to evaluate the results of primary stent implantation after Excimer laser-assisted recanalization of iliac artery occlusions. SUBJECTS AND METHODS: We studied 212 consecutive patients with chronic unilateral iliac artery occlusions (mean [+/- SD] length 8.9 +/- 3.9 cm) who were treated with Excimer laser-assisted recanalization and stent implantation. Based on the criteria of the Society of Cardiovascular and Interventional Radiology, lesions were graded as class III occlusions (<5 cm) in 46 patients and as class IV (> or =5 cm) in 166 patients. A total of 527 stents (Palmaz stent, 346; Wallstent, 94; Strecker stent, 38; covered stents, 49) were implanted. RESULTS: Technical success was achieved in 190 (90%) patients. There was a clinical improvement of three grades in 112 (53%) patients and of two grades in 67 (32%) patients. The rate of major complications was 1.4%, which included arterial rupture (1) and embolic events (2). Primary patency rates were 84% at 1 year, 81% at 2 years, 78% at 3 years, and 76% at 4 years. Secondary patency rates were 88% at 1 year, 88% at 2 years, 86% at 3 years, and 85% at 4 years. CONCLUSION: Stent-supported angioplasty is an effective treatment for iliac artery occlusions, with less morbidity and mortality than is associated with surgery. However, reported long-term patency rates after bypass surgery are greater than those we observed with interventional treatment. The value of primary stenting as compared with angioplasty alone should be evaluated in a randomized trial.
