Abstract

BackgroundIn recent years, several methods and new techniques have been studied and proposed for establishment of sutureless vascular anastomoses, streaming use of sutureless vascular surgery in the future.Presentation of the hypothesisThe new vascular connector (NVC) is a hypothetical design of a vascular device, proposed for creation and maintenance of sutureless vascular anastomosis. Implication of NVC would introduce a new device and technique in establishment of sutureless vascular anastomosis in which surgical approach is minimized and so post-operation disorders. It would eliminate need for suture; shorten clampage and operation time, consequently reducing stress for both, the surgeon and the patient. It enables the creation of vascular anastomosis fast, simple, safe, reliable, with satisfactory patency and stability of anastomosis.Testing the hypothesisEfficacy of NVC needs to be evaluated in further studies, in order to be confirmed for clinical use. The effectiveness of NVC should be verified firstly in vitro and in vivo tests; and by animal experiments. The likelihood of its negative influence in thrombogenicity should be well evaluated.Implications of the hypothesisImplication of the new vascular connector (NVC) would be of interest to both patients and the surgeon due to the following main achievements: 1) enables the creation of vascular anastomosis fast and simple, 2) significant shortening of clampage time of blood vessels and operation time-this assumption would be followed by reduced risk of operative and post-operative complications and length of hospital stay or admission to Intensive care unit, 3) safe and reliable, 4) compatible with any blood vessel and standard vascular graft, 5) using the NVC we will reduce in minimum need for replaced blood volume, 6) reduces the cost of treatment. It is anticipated that the NVC would provide shorter operation time and least operative and post-operative complications in creation of sutureless vascular anastomosis.

Summary

Background

The first scientific attempt to restore vessel wall goes back to January 13, 1894, eight years before the description of the suture technique by Carrel. Proposal of a new vascular connector (NVC) The NVC is composed of three parts, an inner tube with conical ends and the two outer rings, which serve to establish and maintain vascular anastomosis (Figure 2). The external diameter of the inner tube is proportional to the internal diameter of the blood vessel or synthetic vascular graft This allows end-to-end vascular anastomosis to be accomplished almost exactly around the line of artery-artery contact. Safest and most consistent way to create a connection and leak proof sutureless anastomosis, in this technique, is to close fit the ends of the blood vessel over conical surface of inner tube, always maintaining the integrity of the vessel. In this technique, first part of the connector, distal ring, is located initially in the distal part of blood vessel (Figure 4C). According to these results, when compared to sutureless anastomoses, manually sutured anastomoses had a significantly higher tensile strength (p < 0.05), (Figure 7)
