(5) METHOD OF IMPLEMENTING A MICRO-VESSEL SEAM IN THE CONNECTION OF ARTERIES

I

This invention relates to medicine, namely to vascular surgery.

There is a method of applying a microvascular suture when joining arteries using a vaso-linker, during which the ends of the arteries are flared. bushing vasosuyvayuschey apparatus of appropriate diameter The vessels are stitched by pressing a special lever, while the clips slide out of the sleeve grooves and pierce both walls of the 1P vessel.

However, the known method does not allow stitching vessels, small caliber (less than 1.3 mm) and different diameters, which limits the scope of use of the method.

The aim of the invention is to provide cross-linking of vessels of small caliber and of different diameter.

The goal is achieved by the fact that according to the method for; to the wife of the microvascular suture when connecting

arteries using a vasosuyushchaya apparatus the end of the vessel of a smaller diameter before grading on the sleeve of the co-suturing apparatus is cut longitudinally and the ends of the vessels are sutured, and the remaining defect after suturing is sutured with a hand seam.

The method is carried out as follows.

Arteries are isolated from surrounding

10 tissues, interlace the small vascular branches and cross. Excess adventitia is removed from the ends of the arteries. The end of the vessel of smaller diameter longitudinally cut

15 with the formation of two petals, which are placed on the bushing of the vasospacial apparatus just above the staples. The end of the vessel of a larger diameter disassemble the other half

20 bushings in the usual way. After the apparatus has been stitched, the petals are connected with two stapling seams with the other (larger in diameter) end of the vessel and are in wide contact with the intimal surface with the intimal surface of the other end of the vessel turned out. The defect left in the vessel wall along the edges of the petals is sutured with knotted seams. It is convenient to superimpose these seams, since the vessel of larger diameter remains flared intima outside on the sleeve (the second half of the apparatus, on which the petals were disassembled, is removed), and the remaining defect is removed. Knotty seams well model the diameter mismatch. Approbation of the method was carried out in the clinic during the implantation of an imka on the arterial venous pedicle. During this operation, the ichus artery, having an average diameter of 1.1 mm, and the inferior epigastric artery with a diameter of an average I, mm, is stitched together. The method was applied in 6 operated patients with primary hypogonadism. The test results show that the pre-proposed method allows the blood vessels of a small caliber and a different diameter (1.004 1.3 mm) to be connected. In addition, the method facilitates the imposition of the most difficult first two fixing seams, which largely determine the quality of the vascular anastomosis, and also simplifies the imposition of the rest of the manual seams, since it does not allow the vessel of larger diameter to fall. Claims The method of applying a microvascular suture when joining arteries using a vascular-binding apparatus, is characterized in that, in order to ensure the cross-linking of vessels of small caliber and of different diameters, the end of the vessel of smaller diameter is cut longitudinally on the vascular-bushing sleeve and. the ends of the vessels are stitched, and the remaining after stitching the defect is sutured with a hand seam.
