Long-term study of the microvascular sleeve anastomosis: an experimental study in the rabbit renal artery

A long-term study of 5 sleeve anastomoses in rabbit renal arteries was performed. Six months postoperatively angiography, light microscopy and electron microscopy was carried out. Good long-term function of the anastomoses without any stenoses or aneurysm formation was obtained. It was concluded from this study in rabbits that the sleeve technique is suitable for microvascular anastomosis and that good long-term function can be obtained.
