Hyperdense middle cerebral artery sign is not associated with functional outcome following mechanical thrombectomy.
Hyperdense middle cerebral artery sign is not associated with thrombectomy functional outcome.
Hyperdense middle cerebral artery sign is not associated with functional outcome following mechanical thrombectomy.
Arterial hyperdensity on non-contrast CT is a well-recognized indicator of acute thromboembolism within the intracranial arteries.
This study aimed to evaluate the association between the hyperdense middle cerebral artery sign (hyperdense middle cerebral artery sign) and functional outcome in a homogeneous cohort of patients treated with mechanical thrombectomy for occlusion of the M1 segment of the middle cerebral artery (middle cerebral artery).
We conducted a retrospective analysis of a tertiary stroke center prospectively maintained database to identify patients who underwent mechanical thrombectomy for M1 segment occlusion between January 1, 2021, and December 31, 2023.
hyperdensity did not predict better or worse outcomes after thrombectomy
The prevalence of hyperdense middle cerebral artery sign did not differ significantly between patients with favorable and unfavorable functional outcomes.
Patients with favorable outcomes were significantly younger, had a lower prevalence of arterial hypertension, lower NIHSS scores, better collateral status, and a shorter median symptom onset-to-recanalization time.
Lower NIHSS scores and well-developed leptomeningeal collaterals were the strongest predictors of a favorable functional outcome.
Hyperdense middle cerebral artery sign is not associated with functional outcome in patients undergoing mechanical thrombectomy for acute ischemic stroke caused by M1 segment occlusion.
Other clinical and collateral factors are the principal determinants of functional outcome.
