There were explored physical characteristic six polyester surgical threads. Surgical ligature of the metric size 3 (number 2/0) were used. Sutures tested included Ethibond (Ethicon, Great Britain), PremiCron (B.Braun, Germany), Cardioerg (Ergon sutramed, Italy), Ti-Cron (Tyco, USA), Polyester (Volot, Russia), Polyester which poly-p-xylylene (PPX) coating. The results are indicative of significant qualitative superiority of the polyester threads with covering. PPX covering allows qualitative and inexpensively to improve polyester suture material.

Objective: to evaluate the sorption potential of various antibiotics on polylactide and polypropylene surgical threads, whose surface is modified by direct radiation grafting of acrylic acid in the presence of N, N- methylene- bis- acrylamide, and antibacterial properties and capillarity of new surgical suture. Material and methods. The surface of the surgical sutures was modified by direct radiation grafting of acrylic acid. The bond strength of different antibacterial preparations was studied with modified threads. The antibacterial activity of the threads with Levofloxacin was studied against St.aureus, E.coli, Ps.aeruginosa . The capillarity of the modified surgical suture was studied. Results. The new surgical suture has a greater affinity to the fluoroquinolone antibiotics, has a pronounced antibacterial activity against E.coli, St.aureus, Ps.aeruginosa . Conclusion. The new surgical suture material can most effectively be used in surgery for prevention of infectious complications in the postoperative period.

The pathology of extracranial arteries takes a significant place in the structure of diseases, causing insufficiency of cerebral blood circulation. This article describes the effect of carotid arteries tortuosity on cerebral blood circulation, options of the course of vascular insufficiency and its clinical implications, the role of tool research methods in the diagnosis of this pathology and definition of the indications for surgery. Also, the article throws light upon the possible ways of expeditious treatment and possible complications in the postoperative period.

We studied the physical properties of eight polyamide surgical threads and used surgical suture ligatures of the metric size 3 with the agreed number 2/0 of different firms: twisted and braided, uncoated and coated threads. The received results are indicative of the qualitative superiority of braided covered polyamide threads.

The article describes the effect of pathologic tortuosity of carotid arteries on cerebral circulation, variants of the course of vascular cerebral insufficiency and clinical manifestations, their role in indication for surgical treatment. The pathologic tortuosity of carotid arteries is revealed by the clinical picture of vascular cerebral insufficiency in carotid and/or vertebrobasilar basins. The work assesses the role of spiral computed tomography with contrasting and magnetic resonance imaging in the verification of signs of episodes of focal neurologic deficiency in patients with the tortuosity of carotid arteries and the potential for application of transcranial Doppler for evaluation of cerebral blood flow disorders in different variants of cerebral vascular insufficiency. The article covers the problems of analysis of the received data for indication for surgical treatment for the tortuous internal carotid artery and presents the long-term results of the surgical treatment of the patients with tortuosity of carotid artery (dynamics of neurological symptoms and the absence of cerebral infarction on the area of the surgery).
