Background:Suturing of microvascular anastomosis is still a time-consuming procedure, despite the fact that different techniques and devices were designed to reduce the operation time and increase the patency rate. This paper reports a method for microvascular anastomosis suturing, using foam rubber cylindrical mandrel, which helps to solve the above-stated problems.
Methods:The principle of method is based on running suture, imposed around the foam rubber mandrel. Then the suture is divided into separate stitches. After the visual control of anastomosis lumen knots are tightened. The procedure is the same for front and back parts of anastomosis.
Results:Testing of technique in the laboratory showed the possibility of using a single thread per anastomosis and reducing the time for suturing from 17.3 to 15.4 min compared with standard procedure.
Conclusions:Described technique allows surgeon to control the lumen of anastomosis before tightening knots, reduces time of work, and does not increase the cost of operation.

Description of method
This method can be used for any type (end-to-end, end-to-side, or side-to-side) microvascular anastomosis. Auxiliary tool is a foam rubber cylindrical mandrel [
For end-to-end and side-to-side anastomosis suture technique is almost the same. Primarily, two first stitches, 180° one opposite another, at the corners of the artery cut, are placed [
Then, running suture on the rear anastomosis part around the foam rubber mandrel is performed [
Next suturing of the front anastomosis part is performed similarly. After removal of mandrel, the lumen of anastomosis is visually controlled [
The stacking order for the first four stitches on the end-to-side anastomosis at acute angle is shown in
Procedure invention and testing was carried out in the laboratory at 20 femoral arteries of chicken thighs. Ten arterial end-to-side anastomoses were performed in conventional way, using interrupted sutures, and 10 anastomoses were performed, following the above-described method. All the anastomoses were performed by one surgeon during 5 days, 2 per day in the stack of one regular – one modified technique. Time, spent on the anastomosis, was measured from the moment of the first stitch imposition to the removal of thread excess after tightening the last knot.
Rubber foam mandrel technique showed the reducing of time, required for the end-to-side anastomosis from 17.3 to 15.4 min [
A mandrel, required for this technique, does not increase the cost of operations and allows to work in the surgical wound almost of any depth and diameter. Also the described method may be used as an exercise for microsurgical skills training.
0Above-mentioned method allows surgeon to control the lumen of anastomosis before tightening knots, reduces time of work, and does not increase the cost of operation.
