Abstract

The objective of this study was to evaluate the use of 3 types of non absorbable suture materials in arteries and veins suturing. Twelve adult dogs of both sexes was used, the animals was divided into three groups of four animals in each. The right common carotid artery and left jugular vein of each animal was used for application of suture materials. In group one the blood vessels (common carotid artery and jugular vein) sutured with polypropylene suture after inducing about 2cm longitudinal incision on the vessel, in group two polyester suture was used in the same manner of group one, while in group three myo-steel suture was used in the same way of group one and two. The macroscopic and microscopic changes associated with each suture material were studied at 15 and 30 postoperative days. The gross pathological changes associated with polypropylene was that of very mild adhesion and very mild shrinkage and stenosis at the suture line with smooth blood flow, while the groups of polyester and myo-steel suture associated with severe adhesions, shrinkage at the suture line with poor blood flow. The histopathological changes showed that polypropylene suture lead to formation of very few amount granulation tissue at the line of incision, no signs of organized thrombus formation or significant changes of the blood vessels wall, but the polyester suture cause arterial organized thrombus formation and hypertrophy of endothelial wall, while the myo-steel suture lead to formation intense amount granulation tissue which cause to the thickening in the wall of blood vessels with subsequent changes in the normal shape of vessels. In conclusion the polypropylene suture was regarded better and superior than polyester and myo-steel suture materials in blood vesselssurgery.
