Histological changes in venous grafts.

Long-term histological and immunohistochemical findings in human venous aorto-coronary bypass grafts.

The aim of the present study was to analyse the long-term histology and immunohistochemistry of the plaque composition and cellular infiltration of SVGs (saphenous vein grafts) containing metallic stents. Percutaneous interventions in SVGs have a worse long-term clinical outcome compared with stenting of coronary arteries. Whether the pathological features of old degenerated SVGs condition the ...

Histological study of arterial and venous grafts before their use in aortocoronary bypass surgery.

INTRODUCTION In this study we investigated the morphology of grafts from the internal thoracic artery and the great saphenous vein, before their use in aortocoronary bypass surgery, in order to draw conclusions concerning their suitability and viability. MATERIAL AND METHODS Sections of grafts from the great saphenous vein and left internal thoracic artery obtained for use in bypass surgery w...

A Histological Study of Heterologous Tumor Grafts

The histological changes of digestive organs in experimental decreases of hepatic venous outflow at the rat.

The hepatic venous outflow may be diminishing in right-sided heart diseases, constrictive pericarditis, obstruction of suprahepatic veins or an inferior vena cave. It was created an experimental model by obstruction of the suprahepatic veins lumen and inferior vena cave, too, at the adult Wistar rats. The animals were sacrificed in the 30 days after operation. At the iterative laparatomy it was...
