ABSTRACT
Introduction: intracranial aneurysms are pathological enlargement of the brain arteries that are most commonly located in the circle of Willis. Intracranial aneurysms are relatively common with a prevalence of approximately 4%. The real danger of aneurysms is subarachnoid hemorrhage. 3D digital subtraction angiography has become a critical imaging tool in neuroradiology allowing for the visualization of detailed cerebral vasculature prior to any intervention
Aim of the work: The aim of this work is to evaluate the diagnostic performance of 3D conventional angiography in the evaluation of intracranial aneurysms compared with the conventional cerebral angiography
Methods: The studied group included 20 patients [5 men and 15 women] with subarachnoid hemorrhage or known to have cerebral aneurysms. All patients were subjected to conventional cerebral angiography and 3D cerebral angiography, using C-arm [Toshiba] rotational technique
Results: 3D digital subtraction angiography is superior to conventional digital subtraction angiography in 100% of the cases 3D imaging revealed the proper aneurysmal shape, size, precise assessment of its neck and relation to the surrounding vessels
Conclusion: Three-dimensional DSA improves the detection and delineation of intracranial aneurysms
ABSTRACT
Transcatheter oily chemoembolisation was done to 36 patients with hepatocellular carcinoma. 9 patients had underwent the procedure followed by injection of gel foam particles. Surgery was done to 7 patients following the procedure by one to two months. All patients were followed up by Alphaf feto-protein level after 7 - 10 days and by CT after one mouth of the procedure. Alpha feto-protein level dropped in 27 cases to less than 50% compared with the pre-chemoembolisation level and to a level between 50% to 75% of the previous level in 6 cases while no significant changes occured in 3 cases. C.T. showed marked decrease in the tumour size in 5 cases, slight decrease in the tumour size in 23 patients while no change in size occured in 8 cases
