What is a Grade 5 liver injury?
Grade V: laceration: parenchymal disruption involving >75% of hepatic lobe or >3 Couinaud segments within a single lobe; vascular: juxtahepatic venous injuries (ie, retrohepatic vena cava/central major hepatic veins).
What is a Grade 5 injury?
Parenchymal laceration involving segmental or. hilar vessels producing >25% devascularization. V. 5. Any injury in the presence of a splenic vascular.
How many grades are in liver lacerations?
The WSES Classification divides Hepatic Injuries into three classes: Minor (WSES grade I). Moderate (WSES grade II). Severe (WSES grade III and IV).
What grade is a major liver laceration?
The major- ity of patients admitted for liver injuries have grade I, II or III and are successfully treated with nonoperative management (NOM). In contrast, almost two-thirds of grade IV or V injuries require laparotomy (operative management, OM) [2].
What is a Level 4 liver laceration?
grade IV. laceration: parenchymal disruption involving 25-75% hepatic lobe or involves 1-3 Couinaud segments. vascular injury with active bleeding breaching the liver parenchyma into the peritoneum.
How bad is a Grade 5 liver laceration?
Background: Despite recent advances in the management of severe hepatic injuries, the operative mortality rate of grade V hepatic injuries still ranges from 67% to 80%. Grade V hepatic injuries involving the retrohepatic cava or main hepatic veins are almost always lethal, especially those from blunt trauma.
What grade V means?

What is a Grade 3 liver laceration?
A grade III laceration is characterized by a laceration that is > 3 cm of parenchymal depth, a subcapsular hematoma that is > 50% surface area of ruptured subcapsular or parenchymal hematoma, and an intraparenchymal hematoma that is > 10 cm or expanding.
Can you survive a Grade 5 liver laceration?
How is a Grade 2 renal trauma described?
Grade 2: Laceration ≤ 1 cm in depth without urinary extravasation. Grade 3: Laceration > 1 cm without urinary extravasation. Grade 4: Laceration involving the collecting system with urinary extravasation; any segmental renal vascular injury; renal infarction; renal pelvis laceration and/or ureteropelvic disruption.
What is the meaning of B in results?
B (70%-79%) B Grade Pass. C (60%-69%)
How is the treatment of liver trauma determined?
In determining the optimal treatment strategy, however, the haemodynamic status and associated injuries should be considered. Thus the management of liver trauma is ultimately based on the anatomy of the injury and the physiology of the patient.
What is the grade for a liver injury?
As observed, the degrees vary, starting with I, the least severe to VI, the most severe. The rule of thumb states that any injury classified at a stage higher than II will most likely require surgical correction and in some cases, preparation for blood transfusion.
How are liver injuries classified according to the AAST?
The severity of liver injuries is universally classified according to the American Association for the Surgery of Trauma (AAST) grading scale (Table 1) [ 1 ]. The majority of patients admitted for liver injuries have grade I, II or III and are successfully treated with nonoperative management (NOM).
What are the grades of hepatic traumatic lesions?
The WSES position paper suggested dividing hepatic traumatic lesions into minor (grade I, II), moderate (grade III) and major/severe (grade IV, V, VI) [6]. This classification has not previously been clearly defined by the literature.
