Background: The cardiac device implantation is a minor surgical procedure. One of the problems is a suture knot sticking out 1-3 months after operation. A unidirectional barbed suture (V-Loc; Covidien, Mansfield, MA) is a suture with barbs, which enables running sutures without knots. The conventional sutures often leave knot protruding the end of suture line, however V-Loc eliminates need to tie surgical knots and leaves clean surface.
Methods: Total 70 patients underwent cardiac device implantation. Twenty-eight of them were sutured using conventional string (PDS; Ethicon, Somerville, NJ), V-Loc were used on 42 patients. Between two groups, there is no significant difference in patient characteristics. A conventional method is to close a wound in three layers. After approximating the subcutaneous tissue in two layers with 3/0 PDS, finally closing the skin with 4/0 PDS. On the other hand, new technique is to create an over-and-over running stitch on the subcutaneous tissue with 3/0 V-Loc, then closing the skin with 4/0 V-Loc.
Results: The average time to suture was obviously shorter in V-Loc group than conventional group (10.9±1.6 vs. 18.4±3.4sec. P<0.01). It is surprising that reduction in closure time by 43% or 8 mins without complication of wound infection and wound dehiscence. In conventional group, 8 of 28 patients (28.6%) had suture knot sticking out without infection.
Conclusions: Barbed suture material offers the possibility of knotless stitch. It is clearly useful in cardiac device implantation.
