Comparison of Arterial Repair through the Suture, Suture with Fibrin or Cyanoacrylate Adhesive in Ex-Vivo Porcine Aortic Segment.

Introduction: Tissue adhesives can be used as adjacent to sutures to drop or avoid bleeding in cardiovascular operations.

Objective: To verify the efficiency of fibrin and cyanoacrylate adhesive to seal arterial sutures and if the adhesives penetrate through suture line to the inner of arteries.

Methods: 20 abdominal aorta segments of pigs were divided into two groups according to the adhesive which would be used as adjacent to the suture.

Collagen, fibrinogen and thrombin biological addesive is effective in treating experimental liver injuries.

Objective: : to evaluate the effectiveness of a collagen-based adhesive associated with fibrinogen and thrombin in experimental liver injury in rats.

Methods: : the study included 30 Wistar rats randomly divided into three groups: A, B and C. All underwent standard liver traumatic injury.

[Topical haemostatic agents and tissue adhesives].

In the last ten years the hemostatic agents and tissue adhesives have been frequently used and they are positive alternatives to prevent excessive blood loss. The objective of this review is to discuss the characteristics of each of these agents to facilitate the surgeon's decision when choosing the most suitable product for every type of bleeding and nature of hemorrhage. A survey of the literature on the subject, in English and in Portuguese, was conducted using PubMed (www.

[Chest wall reconstruction in acquired defects].

Acquired chest wall defects present a challenging problem for thoracic surgeons. Many of such defects can be repaired with the use of local and regional musculocutaneous flaps, but larger defects compromising skeletal structure require increasingly sophisticated reconstructive techniques. The following discussion will review the options for repair acquired chest wall defects based in literature.
