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 vessels surgery.
Highlights
Vascular surgery deals with blood vessels, these vessels can vary in size and length [1]
Because the selection of an ideal suture material for blood vessels surgery is a controversial point, our present study is designed to compare between three suture materials for closing of incised common carotid artery and jugular vein in dogs and these includes: polypropylene, polyester and myo-steel suture materials, and the study including gross and histopathological changes associated with the application of these sutures
In this study a non absorbable suture material was used because, cardiovascular surgeons have been always reluctant to use absorbable suture material for arterial and venous surgery because of suspected anastomotic dilatation or even rupture during and after the absorption phase [11], while other workers found no significant differences between the polypropylene and absorbable suture material for arterial femoral artery in dogs [12]
Summary
Vascular surgery deals with blood vessels, these vessels can vary in size and length [1]. Bleeding associated with surgery is potentially serious complication, so hemostasis to prevent blood loss is commonly achieved by tying a surgical thread around the blood vessel [2]. Peripheral vascular diseases that are amenable to surgery are rare in dogs, those encountered most commonly have been arteriovenous fistula and systemic arterial embolism [3]. Because the selection of an ideal suture material for blood vessels surgery is a controversial point, our present study is designed to compare between three suture materials for closing of incised common carotid artery and jugular vein in dogs and these includes: polypropylene, polyester and myo-steel suture materials, and the study including gross and histopathological changes associated with the application of these sutures
