What causes subcapsular hematoma?
Subcapsular hematoma of the liver is a potentially life-threatening but extremely rare condition. It is often caused by a blunt trauma or other predisposing conditions such as a liver tumor, intra-tumor hemorrhage, surgery, preeclampsia, liver biopsy, and hemodialysis.
What is a subcapsular liver hematoma?
A subcapsular hematoma of the liver is an accumulation of blood between Glisson’s capsule and the liver parenchyma; rupture into the peritoneum has a 75% mortality rate [1, 2]. The hematoma is usually located around the right lobe of the liver (in 75% of patients).
What causes hematoma in liver?
Liver haematoma is most commonly caused by blunt abdominal trauma, with the liver being the second frequent abdominal organ injured during blunt trauma (after the spleen).
Which grade does subcapsular hematoma have?
Subcapsular hematomas (grade 1) may vary in attenuation value as a function of the age of the clot. Acute hematomas are typically hyperattenuating (40–60 HU) relative to renal parenchyma on unenhanced CT images.
What does subcapsular mean?
Medical Definition of subcapsular : situated or occurring beneath or within a capsule subcapsular cataracts.
What is hematoma in liver?
Spontaneous hepatic hematoma without underlying liver diseases is an uncommon entity. It represents an accumulation of blood between the capsule of Glisson and the liver parenchyma and frequently located around the right lobe (about 75 % of cases) [6]. The underlying cause of hepatic hematoma is varied.
What is liver hematoma?
A liver hemangioma (he-man-jee-O-muh) is a noncancerous (benign) mass in the liver made up of a tangle of blood vessels. Also known as hepatic hemangiomas or cavernous hemangiomas, these liver masses are common and are estimated to occur in up to 20% of the population.
How do you treat a hematoma on the liver?
Treatment
- Surgery to remove the liver hemangioma. If the hemangioma can be easily separated from the liver, your doctor may recommend surgery to remove the mass.
- Surgery to remove part of the liver, including the hemangioma.
- Procedures to stop blood flow to the hemangioma.
- Liver transplant surgery.
- Radiation therapy.
What is a grade 4 injury?
Grade 4: Laceration involving the collecting system with urinary extravasation; any segmental renal vascular injury; renal infarction; renal pelvis laceration and/or ureteropelvic disruption. Grade 5: Shattered or devascularized kidney with active bleeding; main renal vascular laceration or avulsion.
How bad is a Grade 3 liver laceration?
Grade III injury has a 15.7% mortality rate because of its complexity. A simple hepatic parenchymal laceration in the absence of active hemorrhage, diffuse peritoneal signs or other peritoneal injuries, a hemoperitoneum less than 500 mL, and no need for blood transfusions met the criteria for nonsurgical management.
What is subcapsular renal hematoma?
A subcapsular perirenal hematoma is a form of perirenal hematoma where blood accumulates beneath the renal capsular margin.
What is a hepatic hematoma?
Hepatic hematoma is an encapsulated, intraparenchymal blood collection. It is usually located between the capsule of the liver and the parenchyma in the anterolateral aspect of right lobe; however, a hematoma can exist anywhere within the liver parenchyma.
