Bottom Line: It would eliminate need for suture; shorten clampage and operation time, consequently reducing stress for both, the surgeon and the patient.The effectiveness of NVC should be verified firstly in vitro and in vivo tests; and by animal experiments.Implication 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.

ABSTRACT

Background: In 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 hypothesis: The 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 hypothesis: Efficacy 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 hypothesis: Implication 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.

Mentions: NVC is proposed to create a sutureless vascular anastomosis. It bears less stress for both patient and surgeon. Details of the implementation of NVC to establish and maintenance the sutureless vascular anastomosis are schematically presented stepwise in Figure 4. In this technique, first part of the connector, distal ring, is located initially in the distal part of blood vessel (Figure 4C). Then, the second ring is situated in the proximal part of blood vessel (Figure 4D), to proceed with the introduction of fine inner tube with conical ends in the distal and proximal blood vessel (Figure 4E and F). The anastomosis is finalized with closure of outside positioned rings and interlocks both ends of the blood vessel or vascular graft prosthesis, without any gaps, to prevent leakage and eventual formation of late pseudo aneurysm. Consequently, two ends of the blood vessel are connected with each other without any suture (Figure 4G); Antiagregant drugs should be administered to minimize the risk of thrombosis in the postoperative period.Figure 4
