Laceration: A laceration is a wound that is caused by the tearing of soft body tissues. This kind of wound is generally irregular and jagged. Accidents with tools, knives, or machinery could lead to lacerations. A laceration may be caused by injury to a sharp object or due to impact injury from a blunt object. A laceration cut might be shallow or deep, short or long, and narrow or wide.
Arteriovenous malformations: It is the abnormal connection between veins and arteries, usually in the spine and brain. The arteries in such a condition can rupture, leading to bleeding in the brain/spine.
Bleeding gastric varices: Gastric varices are the dilated submucosal veins in the stomach lining that can cause bleeding in the upper gastrointestinal tract. These are most commonly found in patients with portal hypertension (high blood pressure in the portal vein), which could be a complication of cirrhosis.
