Abstract

The invention relates to the technical field of revascularization and vascular repair and discloses a rat model for replantation after vascular injury. A process includes: step one, model selection; step two, rat anesthesia; step three, femoral artery cutting; step four, femoral artery suture; step five, postoperative management. The invention further discloses an assessment method of the rat model for replantation after vascular injury. The rat model which is convenient and quick in modeling, economical, low in cost and extensive in application range is provided for the field of vascular injury and repair research. An extensive platform is provided for researching specialized clinical therapeutic methods for hand surgery, plastic surgery, reparative and reconstructive surgery and the like, application to observation of curative effects of related medicines used after vascular injury is realized, and whether endangium, smooth muscle cells and related vascular activating factors participate in a repair process or not and related mechanisms in a vascular injury and repair process can be explored.

Description

technical field [0001] The invention relates to the technical field of blood vessel regeneration and repair, in particular to a rat model for replantation after blood vessel injury and an evaluation method thereof. Background technique [0002] With the development of modern industry and agriculture, in the process of labor, workers are accompanied by a higher risk of trauma, such as machine strangulation, cutting injuries, limb amputation injuries, etc. Similar serious injuries have caused great physical harm to working people, seriously threatening the safety of their lives and property, and many traumas can even cause disability, which has an irreversible impact on the normal life of patients in the future. Therefore, for trauma, timely treatment and surgical intervention are the key to improving the treatment effect and reducing postoperative complications and disability rate, and the anastomotic technique of damaged blood vessels in minimally invasive surgery is the key...
