Abstract:
The method of vascular anastomosis formation was elaborated. Formation of the anastomosis on the spiral nitinol carcass, consisting of a diameter 0.1 mm nitinol thread, constitutes its advantage. An excellent passability of vascular anastomoses, the compensated blood flow in anastomotic area were noted, according to the patients follow-up duplex scanning data in terms from 5 to 12 months. Application of the method proposed have permitted to reduce significantly postoperative morbidity, to shorten duration of the anastomosis formation and to prevent vascular stenosis.

Anastomoses
In human anatomy, anastomosis refers to a connection or opening between two things, particularly between blood vessels or other tubular structures. The term is derived from the Greek term 'anastomosis,' which means 'outlet' or 'opening.' This natural network of connections plays a critical role in the survival and functionality of the human body.
Anastomoses can be formed at arterial, venous, and lymphatic vessels.

Mechanism of Angiogenesis
Blood vessel formation starts early during embryonic development, around day 7. In the extraembryonic yolk sac, mesodermal precursor cells called hemangioblast proliferate and differentiate into angioblast. Angioblasts express vascular endothelial growth factor receptor 2 or VEGFR2, which binds VEGF-A, a proangiogenic factor, guiding blood vessel formation. VEGF signaling promotes angioblasts to form a blood island in the developing embryo. Angioblasts further differentiate, giving rise to...
