A technique for ligating the end of a running polypropylene suture or for securing inadvertent loops is described. This method was used in 700 pediatric cardiac procedures without failure of ligation.

 DISCUSSION

Continuous suturing with polypropylene or other monofilament suture is the most frequently used technique in cardiac surgery. If cross-clamping or perfusion time is destined to be lengthy, one has to choose a timesaving but effective method for every aspect of the surgical procedure. We describe a quick and effective method of tying the stitches at the end of a running polypropylene suture. This technique can also be applied when an inadvertent loop is made during suturing.

Just before the last stitch (Figure lAGo), a loop is made and a no.3 silk is passed through it to pull the two arms of the loop evenly (Figure lBGo) and tied with the last stitch (Figure lCGo) three times in one direction and then three times again by changing hands. If a loop is made inadvertently, the same technique can be applied (Figures 1D, 1E, 1FGo). If the inadvertent loop is long enough (Figure lGGo), it can be cut (Figure 1HGo) and tied as before (Figure 1IGo). We have applied this technique in our last 700 pediatric cardiac operations without failure of ligation.

Figure 1. (A, B, C) At the end of a running suture, a no.3 silk suture of suitable length can be passed through the loop to facilitate even tying. (D, E, F) If an inadvertent loop is made during a running suture, the same technique can be applied. (G, H, I) If a long loop was made inadvertently it can be cut and self-tied.

The alternative method of securing running stitches is to insert another stitch and tie them together as in Figures lE and lFGo.1 However, our technique is less complicated. When inserting a running suture, inadvertent loops that are long enough for hand ligation or instrument tying, can be cut and tied; but if the loop is short our technique is recommended.
