Influencia del grado de la severidad de la estenosis, del diámetro del vaso y del modelo de stent en el fenómeno del retroceso elástico en angioplastia coronaria. Evaluación angiográfica

Purpose: Stent recoil following stent deployment is still a very important outcome predictor after angiographic intervention. The aim of this study is to assess the influence of device model, angiographic characteristics of the lesion and vessel size on stent recoil. Methods: 61 consecutive patients...

Descrição
Resumo:Purpose: Stent recoil following stent deployment is still a very important outcome predictor after angiographic intervention. The aim of this study is to assess the influence of device model, angiographic characteristics of the lesion and vessel size on stent recoil. Methods: 61 consecutive patients were included in the study. 81 stents were successfully deployed. Maximal balloon diameter at peak pressure and maximal lumen diameter after stenting were measured by QCA (quantitative coronary angiography) Results: There were no significant differences regarding either the model of device or length, symmetry or severity of the lesion. There were significant differences regarding the vessel size. Stent recoil was greater in small vessels (<2,75 mm). Discussion: This finding is a paradox. The small size of the vessel has been always identified as an independent risk factor for the development of stenosis. The use of stents in small vessels remains controversial.
