Micro-arterial anastomosis using only two sutures and an autogenous cuff.

Microvascular anastomosis using only two sutures and an autogenous cuff was carried out in an experimental model of Wistar albino rats. 40 femoral and 40 epigastric arteries were used for this cuff technique and compared with conventional technique in the same number of vessels. The cuff technique is simple, quick, causes less trauma to the vessel wall and gives a good patency rate. Anastomosis of an artery 0.5mm in diameter is very easy with the cuff technique (98% patency) which remains difficult using conventional technique (0% patency). The disadvantage of this technique may be leakage of blood just after releasing the clamps due to restoration of blood flow, but this is easily controlled within few minutes by mild compression.
