- Description
- Objective: This study aimed to determine whether baseline delayed filling of the superficial middle cerebral vein (SMCV) was an independent cause of stroke prognosis in patients with acute anterior large vessel occlusion (LVO). Methods: Consecutive patients with acute LVO [middle cerebral artery M1 ± intracranial internal carotid artery (ICA)] between March 2019 and May 2020 were included. Delayed SMCV was defined as delayed filling of SMCV in the affected side compared with the normal side throughout the venous phase on four-dimensional computed tomographic angiography (4D-CTA) reconstructed from CT perfusion imaging. The modified Rankin scale (mRS) was used to evaluate the prognosis of these patients 3 months after stroke. Results: Of 54 patients in total, 47 (87.0%) patients presented with baseline delayed SMCV, and 36 (76.6%) patients achieved SMCV reversal (ipsilateral delayed SMCV reversed to bilateral symmetrical SMCV) after reperfusion therapy. Successful reperfusion was independently associated with SMCV reversal [odds ratio (OR) = 69.328, 95% confidence interval (CI) = 2.818–175.342]. A significant association between baseline SMCV delay and a 3-month poor outcome (OR = 19.623, 95% CI = 1.567–245.727, p = 0.021) was observed using a multivariable regression analysis. Compared with patients with persistent delayed SMCV, patients with reversed SMCV did not show a significant difference in the risk of a 3-month poor outcome (OR = 1.177, 95% CI = 0.147–9.448). Conclusions: In patients with acute LVO, baseline delayed SMCV was an independent cause of poor stroke prognosis, and SMCV reversal cannot reverse the 3-month stroke prognosis. Therefore, the evaluation of baseline SMCV filling status should be strengthened in clinical practice.
