main task facing the surgeon during surgery for damage to the blood vessel, is to restore the integrity of its walls and terrain.This goal can be achieved in various ways.The simplest method used more often than others, suturing the damaged vessel wall by means of vascular seam.However, in some cases (large defect, crush injury of the vessel wall) suturing the damage becomes impossible, and then resorted to plastic container, ie. E. The replacement of the damaged section of graft.Very particular preference is given to currently autovein, t. E. Replacement of the damaged section of the artery vein taken from the same patient.Saphenous vein graft big Vienna hip often is.The ability to replace the defect artery and corrugated synthetic prostheses.
The patient depends on the location of damage.On the operating table is always laid the wounded man on the wiring.If bleeding continues, the harness is tightened;in arresting bleeding tourniquet should be diss
Analgesia. possible, should operate under general anesthesia, particularly if the recovery operation to produce container.
Tools: general surgical suite, Vascular set sosudosshivayuschy apparatus atraumatic needle, vascular prostheses.
course of operations. surgical wound is treated by conventional surgical methods, excised wound edges.All manipulations on the wounded vessel is carried out in the last turn.When excision of edges and bottom of the wound is fully completed, all instrumentuya should be changed;Surgeon washing hands with antiseptic solution and change gloves.These precautionary measures infection vessel used for secondary prevention of bleeding as a result of purulent fusion of the vessel wall.
highlighted and carrying out an audit of the damaged vessel, the surgeon makes the final decision about the necessity and the possibility of restoring the continuity of the vessel.If the surgeon decides to tie a vessel, then at each end of the artery, he brings two ligatures and tying them at a distance of 4-5 mm from each other.The vessel was ligated with silk thread №4.If possible the recovery operation on the vessel, then applied a side seam or container cross-linked end to end.If necessary, resorting to any transplant graft vessel into the resulting defect.During vascular suturing vascular lumen linkable repeatedly washed with a solution of heparin (5000 IU per 100 ml of isotonic sodium chloride solution).After the restoration of the vessel patency, if the wound is fresh and malozagryaznennaya if it does not crush the tissues, it is sewn up tight.Otherwise, leave the wound drains for aspiration.
