The value of computerized tomography in diagnosis of hepatic trauma

Background: Hepatic trauma is a common disease in surgical emergency. Nowadays, there are many means of diagnostic imaging such as ultrasound, computerized tomography, magnetic resonance imaging.. but computerized tomography is more valuable in the diagnosis and treatment decisions. Objectives: To assess the value of computerized tomography in diagnosis of hepatic trauma. Subjects and method: To conduct computerized tomography on 36 patients with hepatic trauma (28 male, 8 female, aged 5-70 year olds), was diagnosed by ultrasound in Viet Duc hospital from January, 2005-June, 2005. Results: Major cause of the trauma was still due to traffic accidents (77.8%), followed by living and occupational accidents (61.5%). Using computerized tomography, there were only 12 patients undergoing surgery, the remainders were conservative treated. The common signs were: fluids in abdominal cavity: 33/36 patients (91.7%), without fluids in abdominal cavity: 3 patients. Parenchyma crush: 28/36 patients (77.8%). The most common lesion site was right liver. Diagnostic CT scans at 4 or more degrees was necessary during considering surgical indication for cases of having combined injuries, which can lead to hemodynamic dysfunction. Therefore, clinicians tend to use conservative therapy in hepatic trauma. Conclusion: CT scans was chosen as major examination to determine exactly level of lesions and to decide procedures.

CT scanner in the diagnosis of pancreatic injury

This study introduced the signs for identifying the pancreatic lesion due to injuries on films of CT scanner and role of CT scanner in identifying the pancreatic lesion due to close abdominal injuries. In the pancreatic injury, the X-ray and ultrasound only allowed to think of diagnosis and can not identify the lesion of pancreatic parenchyma as well as evaluate the extent of lesion, especially in emergency. When the suspected symptoms occurring, it should implement CT scanner to determine the lesion and timely manage.

Value of ultrasound and CT scanner in diagnosis of gallbladder cancer

13 patients with the gallbladder cancer diagnosed by ultrasound in which 6 patients received CT scanner, these images compared with the operational results and pathological anatomy. The gallbladder cancer occurred most frequently in the elderly and had the poor prognosis. The ultrasound showed the unfair thickness of gallbladder wall (66.7%) rough tumor from the posterior wall to gallbladder

Ultrasound via vagina in the diagnosis of ectopic pregnancy

The ectopic pregnancy is an obstetric emergency that needs to early diagnose and timely treat. The ectopic pregnancy can be found in the ovary, ovary tube or abdomen. The ultrasound can be implemented without needing the full urine in the gallbladder, even the uterine inclined toward the back. The results have shown that the fetal heart beat of 3/45 cases, blood aggregation in the ovary tube of 25/45 cases and fluid in the Douglas of 40/45 cases found by the ultrasound. The early diagnosis of the ectopic pregnancy can present the complication of intraabdominal bleeding from which it can be treated by endoscopy and without intervention of operation

The diagnosis of brain tumor by CT scanner in Viet Duc hospital during 1996 - 1997

An analysis of 270 patients with the brain tumor with the results of pathological anatomy diagnosed by CT scanner in Viet Duc hospital during 1996 - 1997 has shown that it was not difficult to diagnose the meningeal tumor (21.9%), pituitary tumor (10.4%), craniopharyngeal tumor (4.8%) and metastatic tumor by CT scanner. But it was difficult to diagnose the spider tumor (14.8%) by CT scanner because of atypical signs.

Benefits of spiral CT scanner in the diagnosis of the abdominal aortic aneurysm in Viet Duc

The ultrasound Doppler and spiral CT scanner implemented in 19 patients with the abdominal aortic aneurysm have shown that the abdominal aortic aneurysm occurred most commonly in men over 60. The spiral CT scanner were frequently applied to exam before an operation because it overcome the limitations of ultrasound Doppler and angiography. In addition to, the spiral CT scanner had short time of procedure, can set up the three dimensional images with good quality which helped evaluating precisely the condition of arteries and determining the relation of the renal arterial aneurysm and discovering the renal stenosid and accessory renal stenosid as well as risks of rupture.
