Zusammenfassung:Purpose Diagnostic cerebral digital subtraction angiography (DSA) is an invasive examination that involves catheterization of the major supra-aortic arterial trunks and evaluation of intracranial vessels for diagnostic purposes. Although considered the gold standard method for investigating cerebrovascular diseases, DSA carries measurable and potentially serious complication rates. This report describes the frequency of neurological and non-neurological complications of DSA performed in five hospitals in the state of São Paulo, Brazil, and analyzes them in different disease subgroups. It has a special focus on thromboembolic cerebral complications. Methods We retrospectively reviewed clinical records of all adult patients who underwent DSAs between January 2019 and December 2022. Demographic variables, DSA reports, CT/MRI reports, and clinical follow-up notes were reviewed. Results Twenty-four patients experienced some type of complication among 2,457 diagnostic DSAs (0.97%). Thromboembolic complications were recorded in 9 patients (0.36%), and access site hematomas larger than 5 cm were registered in six patients (0.24%). There was a statistical trend for thromboembolic complications in patients with cervical and/or intracranial atherosclerosis (p = 0.07), but age was not associated with them (p = 0.93). Patients who received heparin had lower rates of embolic complications than those who did not receive it, but there was no statistically significant difference (p = 0.17). Intravenous administration of heparin showed a trend toward significance with groin hematoma (p = 0.10). Conclusion Diagnostic catheter DSAs have low complication rates.
