Descriptive retrospective analysis of the diagnostic yield and morbidity of four vessel catheter-directed cerebral angiography and multidetector computed tomographic angiography (MDCTA) performed at Inkosi Albert Luthuli Central Hospital (IALCH).
Imaging studies are indispensable in order to determine the source, location and pattern of intra and extra-axial brain haemorrhages. In our study of 277 patients carried out over an 18 month period, the most common reason of referral was subarachnoid haemorrhage followed by trauma. Aneurysms were the most common diagnosis (36%) with anterior and posterior communicating arteries being the most common locations. Fifty percent (50%) of patients investigated had a normal study. Our findings show that the yield from MDCTA and conventional angiography was relatively comparable, however, conventional angiography was superior in detection of aneurysms; hence, in cases were the MDCTA result was found to be normal despite a high index of suspicion for a subarachnoid haemorrhage, a follow-up MDCTA study or conventional angiography is useful. Moreover, conventional angiography was superior in detection of multiple aneurysms.
