Role of Repeat Digital Subtraction Angiography in Acute Spontaneous Intracranial Haemorrhage of Unexplained Origin

Objective: to evaluate the role of repeat digital subtraction angiography in acute spontaneous intracranial haemorrhage of unexplained origin. Methods: This was a cross-sectional observational study. A total of 70 patients were included in the study. CT scan examination was done in all the patients. All patients had DSA with diatrizoate meglumine and diatrizoate sodium via transfemoral route. Results: CT was positive among 97% (68/70) patients. Out of 70 patients, initial DSA was failed to demonstrate the cause of acute spontaneous intracranial haemrrhage among 75.7% (53/70) patients. 15.7% (11/70) were suggestive of aneurysm, 7.1% (5/70) were AVM and 1.4% (1/70) had tumorogenic. Among 53 patients with negative DSA, 62.3% (33/53) were hypertensive origin and 37.7% (20/53) were non-hypertensive. Conclusion: This study shows that the false negative rate is nil and DSA is the serious undertaking. With this fact that it is concluded that repeat pandigital subtraction angiography is not required unless further bleeding occur.
