Doctor insights on:
Weak veins: Subconjunctival hemorrhage is due to leakage from fragile veins in the conjunctiva. This can be caused by rubbing the eye, sneezing, straining and light trauma. Frequently no cause is identified. Almost always it is benign and will absorb with no consequences. See your ophthalmologist if it is recurrent. ...Read moreSee 2 more doctor answers
Only with time: Subconjunctival hemorrhage occurs when a blood vessel on the eye's surface develops a microscopic tear. Although it heals almost immediately, the blood that leaks out is stuck under the conjunctiva. The blood will naturally be resorbed and removed by the body, much like a bruise. There is no treatment that can speed this process, which can take up to a few weeks. ...Read moreSee 2 more doctor answers
Hematoma- blood coll: Hematoma is collection of blood somewhere in the body...anywhere in the body....it's called a hematoma. Parietal tells us the location (Parietal lobe of the brain) usually due to high blood pressure while Subdural hematoma means collection of blood below the level of the DURAL cover of the covering of the brain called the meninges...often times traumatic cause but also often can be spontaneous. ...Read more
Different: A hematoma is like a bruise or collection of blood from a trauma. In parietal hematoma this is in the parietal lobe of the brain, so it is in the brain tissue itself. A subdural hematoma is just under the dura mater one of the coverings of the brain so it is up close to the skull. ...Read more
Increased pressure: When a subdural hemorrhage occurs, the blood flows and first puts pressure on the soft tissues of the brain until they are fully compressed. The blood pressure then fills the dura mater, the tough sac that surrounds the brain. We think it is actually this stretching that is causing the headache. The pressure on the brain tissues causes the damage. ...Read moreSee 1 more doctor answer
Bleeding in retina: The retina, the seeing film at the back of the eye, is richly vascularized and vessels can bleed from a variety of conditions. This is termed retinal hemorrhage. It is seen in patients with trauma, diabetes, macular degeneration, sickle cell anemia, leukemia, aplastic anemia, blood clotting abnormalities and a host of rare conditions as well. ...Read more
Dangerous hemorrhage: Subaracnoid hemorrhages usually occur from rupture of aneurysms. Aneurysms are caused by defects in the vessel wall producing outpouching of the wall. With rupture of the aneuysm, patients complain of the worst headache of their life. The headache can rapidly progress to include altered consciousness, weakness or unresponsiveness. A percentage of patients never survive to reach medical care. ...Read more
Yes: Imagine a pressure on one side of the brain from the skull, pushing that side of the brain compressing all the tissues including the blood vessels causing brain hypoxia on one side. It then pushes the whole brain and shifts to the brain against the unyielding skull to the other side, compressing the tissues there also (counter coup effect). That is epidural hematoma without surgical treatment. ...Read more
Can diffuse haemangioma in skull bone cause Subdural Hematoma or cavenous sinus thrombosis so worried?
Blood clot: A subdural hematoma is a blood clot that has formed on top of the brain and underneath the covering of the brain. It is usually due to a traumatic event or if the patient's blood is being thinned. It can be nonsurgical or surgical depending on how large it is and what the patient's neurological status is. ...Read moreSee 1 more doctor answer
Blood around brain: There are three layers of tissue that surround the brain, known collectively as the "meninges." the outermost layer is the dura mater, the middle layer the arachnoid mater, and the layer closest to the brain the pia mater. When veins that go between these layers rupture - often because of trauma - blood can start to pool between the dura mater and arachnoid mater causing a subdural hematoma. ...Read moreSee 1 more doctor answer
Subchorionic hemorrhage, placental abruption, oligohydramnios (20w3d). What does this all mean? Is it serious?
Placenta: This means there is a collection of blood between the placenta and the uterine wall- therefore the abruption, the term oligohydramnios basically means low amniotic fluid and can have multiple causes including placenta dysfunction on the side of the mother, of problems with the fetus- problems with the kidneys. Please speak to your physician and seek a referral to a perinatologist. ...Read moreSee 1 more doctor answer
Cell death: Necrosis is cell death. Anything that disrupts the complex system that keeps cells alive can cause cell death. Subarachnoid hemorrhage is a bleed in the brain. The pressure from extra blood in a small space can crush cells, and disrupt fragile capillaries that bring oxygen to cells. This, cell death ...Read more
Probably not.: Blood clots are the result of hemorrhage or blood stasis, not the other way around. Minor trauma could theoretically cause a cerebral hemorrhage if there was a pre-existing aneurysmal weakness in the blood vessel wall. Sometimes these can be congenital, and sometimes these are due to vascular disease (e.g., atherosclerosis, diabetes type ii). ...Read more
Pregnancy Bleeding: A subchorionic hemorrhage/hematoma is a bleed between the pregnancy and the uterine wall. It is an US finding, that if coupled with vaginal bleeding, can potentially increase the risk of miscarriage/preterm delivery, but w/out vaginal bleeding, it's hard to say. Size matters; worse if bigger (covering ~50% of placental bed) or occurring later. It can heal itself, but you just have to wait/watch. ...Read moreSee 1 more doctor answer
What is multiple haemorrhagic contusions in right temporal lobe with subarachnoid haemorrhage? Is it dangerous?
An injured brain: Sounds like someone sustained significant traumatic injury to the brain. Brain tissue has sustained a contusion or a severe bruise bad enough to cause bleeding that has extended to the fluid spaces around the brain. This is more severe than a concussion. Some damage to the brain has occurred. The severity of the injury will be evaluated best after the acute injury has resolved. ...Read more
