CT diagnosis of traumatic brain injury and clinical significance of Discussion
Scalp showed thickening of uneven density. Associated with skull fracture, 24 cases, l5 cases of interruption of linear skull fractures can be seen, not coherent. 20 cases of depressed fracture of the skull plate retraction or distortion can be seen, of which 4 patients had some bone fragments into the brain tissue slices. There were no changes in cerebral contusion hematoma. 2.2 subdural hematoma epidural hematoma and subarachnoid hemorrhage, 88 cases were associated with scalp lacerations and skull fractures, while the hematoma is located below the skull fracture. ① epidural hematoma in 45 cases of high-density double-convex stove, depending on their different sizes and different pressure on the brain; two cases were large, with lateral pressure and deformation. ② subdural hematoma in 29 cases, all with varying degrees of cerebral contusion. Mainly distributed along the crescent-shaped brain convex high-density areas. Epidural hematoma and subdural hematoma, the difference is: epidural hematoma than its predecessor, the shape of a convex lens-shaped; subdural hematoma, widely distributed along the convex surface of the brain distribution of crescent-shaped,[link widoczny dla zalogowanych], and the ratio of dura mater hematoma thin, light brain tissue pressure. ③ l4 cases of subarachnoid hemorrhage, 3 of them were children under the age of l0. CT showed slit pool hemorrhage, was high-density longitudinal band-like lesions. ll adult patients, CT showed subarachnoid space, including cisterns, sulci, and ventricles with high-density lesions. 2.3 cerebral contusion and intracerebral hematoma were 40 cases. Are associated with scalp lacerations and skull fractures, subdural hematoma, both of which ll cases of cerebral contusion injury lesions hedge: the performance of the CT, in addition to the scalp laceration, fracture, subdural hematoma performance, the injured brain organizations within which low-density lesions scattered unevenly punctate high density in a small hemorrhage, foreign sprinkle of salt and black pepper compared. Lateral pressure with the situation as the size of brain damage. 23 cases brain damage such as weight, and edema formation, was under pressure to hernia formation. Hematoma showed homogenous round or irregular-shaped mass of high density, some bleeding from the laceration point of a combination. Near the brain surface, the middle of crack or fissure, and break into the subarachnoid space. Deep brain in or near the ventricle hematoma and break into the ventricle. The patients, of which there are 9 cases of brain surface due to close, while breaking into the subarachnoid space, 5 cases of cerebral contusion near the lateral ventricles, while breaking into the lateral ventricle. A total of 582.4 l7 cases of traumatic cerebral infarction. Few reports of traumatic cerebral infarction at home and abroad, the occurrence rate of 1.85%, the group of 17 patients, the rate was 9.44%. Its shape,[link widoczny dla zalogowanych], density, and no difference in the general cerebral infarction, commonly found in the basal ganglia, corona radiata area,[link widoczny dla zalogowanych], was sheet, strip, to be excluded with a history of trauma before being diagnosed pre-existing lesions. 3 Discussion 3.1 Once brain injury, the importance of timely rescue, treatment, once missed the opportunity to leave will result in death or serious complications and even become a CT can accurately show the damage the disease, and safe, no pain, no damage, fast. The patients, as did CT examination time, improve accuracy of diagnosis of brain injury, so that the mortality rate reduced to zero. CT examination is currently head injury has been listed as the first choice examination items. 3.2 for the head injury, CT is shown ① value of cerebral edema; ② cerebral contusion; ③ traumatic intracranial hematoma and cerebral infarction and so on. The fracture of the skull plain film can only show. Cerebral angiography indirect understanding hematoma formation. Compared with CT, obviously not keep up with clinical diagnostic requirements. The patients, provided treatment to clinical basis. In particular, l28 cases epidural hematoma and brain contusion, intracerebral hematoma cases, play a guiding orientation for the role of surgery, the rehabilitation of patients is guaranteed. 3.3 The structure of the head,[link widoczny dla zalogowanych], a skull for a brain scalp. Once the injury by external force is often combined a variety of tissues damage. Epidural, subdural hematoma, which show different because of their anatomy. The patients seen: ① epidural hematoma, hematoma in the temporal area and more, the amount of roof area. Dried dura mater and the skull adhesion by the close, more than the limited scope of hematoma to form a double convex lens-shaped; ② subdural bleeding is not normal. Occur in the cerebral hemispheres convex, dura and arachnoid blood between the living. The arachnoid without tension, so that the blood of the potential subdural space occupy a wide range of hematoma formation,[link widoczny dla zalogowanych], hematoma thickness of the thinner. ③ hematoma occurred in the frontal or temporal lobe, or hedged positions in the force. Bleeding from broken blood vessels from the brain; also a combination contusion bleeding. With hypertensive intracerebral hemorrhage occur in the basal ganglia, thalamus, multi-surface ... in the brain. ④ traumatic cerebral infarction is common in the basal ganglia, corona radiata area, was sheet, strip, to be excluded with a history of trauma before being diagnosed pre-existing lesions. 0
