What does intimal hyperplasia Mean?
By definition, intimal hyperplasia is an abnormal accumulation of cells in the vascular tunica intima; the cell number is increased because of proliferation and/or migration of vascular wall cells, predominantly smooth muscle cells, often in response to a traumatic stimulus. 1.
What’s a vascular injury?
Vascular trauma means that a blood vessel has sustained some kind of injury. Sometimes, these injuries involve a tear or puncture that causes blood loss. Other times they cause damage to the vessel from crushing or twisting.
What is laceration of blood vessels?
Laceration/Transection: Laceration and transection is produced most commonly by blunt trauma as well as by high velocity missiles which cause irregular tears in the vessel or segmental loss associated with other tissue injuries as well. A cleanly transected artery will often constrict and retract limiting blood loss.
What causes trauma to blood vessels?
What causes vascular injuries? The most common vascular injuries are impacts to the blood vessels. The most common of these include traffic, work, and home accidents, in some cases. On rare occasions, the vascular injury may be caused by trauma such as a stab wound.
What is mild intimal thickening?
Intima-media thickness (IMT) is a marker of subclinical atherosclerosis (asymptomatic organ damage) and should be evaluated in every asymptomatic adult or hypertensive patient at moderate risk for cardiovascular disease.
What happens if a vein bursts in your leg?
A ruptured varicose vein may not stop bleeding, and without medical attention may result in a serious amount of blood loss. Excessive blood loss can, of course, be a very serious problem that can even lead to death.
What is the difference between an incision and a laceration?
An incised wound is an injury to the skin caused by a sharp cutting implement such as a knife, broken glass, or a surgeon’s scalpel. A laceration is a tearing or splitting of the skin caused by blunt trauma, such as a blow from a fist or foot or with a hammer or baseball bat.
What is the first process that occurs after a blood vessel is damaged?
Hemostasis or haemostasis is a process to prevent and stop bleeding, meaning to keep blood within a damaged blood vessel (the opposite of hemostasis is hemorrhage). It is the first stage of wound healing. This involves coagulation, blood changing from a liquid to a gel.
Which of the following is a consequence of intimal thickening?
Progressive thickening of the intima leads to narrowing of the lumen, a reduction in graft flow, and intraluminal thrombosis (Fig. 63.8).
