Experimental work in vascular microsurgery

الملخص EN

This is a preliminary experimental study on 30 human placentas as a model for microvascular practice.

two types of vascular anastamotic techniques were practiced, end–to end and– to–side anastamoses on 78 vessels including both arteries and veins.

vessels of different sizes where divided and reanastamosed under the operative microscope.

Absence of a dynamic circulation was the main disadvantage of the human placenta when used as an alternative model for microvascular practice, otherwise it was very practical, cheap and has many features in common with the clinical situation.

This study shows that arterial anastamoses is easier and less time consuming than venous anastamoses and shows also that end–to– end anastamoses is technically easier and less time consuming than end–to–side anastamoses using the same suture material and vessels of the same size group.
