Summary
Micro-venous anastomosis using the external jugular and posterior facial vein in rats were performed.
The patency rate employing 19 methods using 6 kinds of drugs was examined. A combination of heparin i.v. and topical procaine was found to be the most effective.
After reviewing the literature and our experimental results, we discuss the problems of micro-venous anastomosis, and conclude as follows,
-
1.
venous spasm is a very important factor influencing postoperative patency,
-
2.
an anastomosed vein is very apt to thrombose,
-
3.
application of appropriate drugs is necessary,
-
4.
it is effective to cut a vein obliquely at an anastomosis only when appropriate drugs are used,
-
5.
recanalisation takes place very often at a micro-venous anastomosis within 2 weeks.
