CEREBRAL ANGIOGRAPHIC FINDINGS IN NON TRAUMATIC INTRACRANIAL BLEED: UNENHANCED COMPUTED TOMOGRAPHIC CORRELATION
Journal Title: Journal of Evolution of Medical and Dental Sciences - Year 2015, Vol 4, Issue 41
Abstract
[b] AIMS:[/b] The aim of this study is to correlate the angiographic findings in spontaneous intracerebral haemorrhage with the CT determined site of haemorrhage, age of the patients, and preexisting hypertension. It includes 62 cases of non-traumatic intracranial haemorrhage detected by CT at Government Medical College, Kozhikode, who underwent four vessel angiography via the transfemoral route from December 2013 to Sept. 2014. An attempt was made to predict the site of ruptured aneurysm causative for subarachnoid haemorrhage from NECT, which was compared with four vessel cerebral angiography. Association between independent variables was tested using the χ2 test, p<0.05 being significant. Validity parameters were used to compare CT with DSA for localisation of ruptured aneurysm. [b]RESULTS: [/b]Angiographically detectable cause for non-traumatic intracranial haemorrhage was obtained in 85.5% cases evaluated. The most common vascular abnormality identified in the study was aneurysm (77.4%), followed by arteriovenous malformation (8%). 14.5% cases were angiographically occult. Among aneurysms, maximum number of ACom aneurysms were detected (45.8%), followed by ACA and MCA (18.8% each), PCom (14.6%), and 2.1% by basilar top aneurysm. Distribution of subarachnoid blood in the first CT after aneurysm rupture can be used to predict site of aneurysm rupture in case of ACA/Acom aneurysm rupture with reasonable specificity and positive predictive value, but not so in the case of MCA or posterior circulation aneurysms. According to this study there is no significant association between age, sex or presence or absence of hypertension and occurrence of angiographically detectable cause of non-traumatic intracranial haemorrhage. [b]Conclusions:[/b] Thus all cases of non-traumatic intracranial haemorrhage should be evaluated by cerebral angiography irrespective of age, and hypertensive status.
