一、血管损伤的类型1.血管挫伤:动脉管壁挫伤后,引起内膜粗糙和凝血活酶释放易形成血栓,也可在血管壁间形成血肿,这两种情况均可阻塞管腔,引起组织缺血。2.血管部分裂伤:管壁部分呈横形或纵形破裂,当呈横形裂口时,血管壁平滑肌向两端收缩,裂口敞开,故持续性出血难以控制。3.完全断裂:两断端弹力纤维及平滑肌收缩,管腔缩小,两断端退缩到血管外膜或周围组织内,反而有利于形成血栓和止血。4.继发性出血:血管损伤出血停止后又因凝血块脱落或挫伤的血管壁破裂而出血。二、血管损伤的处理血管损伤的处理原则:急救止血,血管清创,大血管需进行修补、吻合,甚至移植。1.控制出血:
First, the type of vascular injury 1. Vascular contusion: arterial wall contusion, causing rough endometrial and thromboplastin easy to form a thrombus release can also form hematoma in the vessel wall, both cases can block the lumen, causing Tissue ischemia. 2 vascular partial laceration: the tube wall was horizontal or vertical rupture, when the cross-shaped rupture, the vascular wall smooth muscle contraction to both ends, open the gap, it is difficult to control the persistent bleeding. 3. Completely broken: two ends of the elastic fibers and smooth muscle contraction, lumen narrowing, the two ends retreat to the vascular adventitia or surrounding tissue, but conducive to the formation of thrombus and hemostasis. 4. Secondary hemorrhage: vascular injury bleeding stopped bleeding due to clot off or contusion of the ruptured blood vessel wall. Second, the treatment of vascular damage The principle of treatment of vascular injury: emergency hemostasis, debridement of blood vessels, large blood vessels need to be repaired, anastomosis, and even transplanted. 1. Control bleeding:
