Clinical and neuroimaging features of spontaneous convexal subarachnoid hemorrhage complicated with acute cerebral infarction / 中华神经医学杂志

ABSTRACT

Objective:To investigate the clinical and imaging features of spontaneous convexal subarachnoid hemorrhage (cSAH) with acute cerebral infarction.Methods:Nine patients with cSAH complicated with acute cerebral infarction, admitted to our hospital from January 2018 to October 2021, were selected. The clinical data and efficacy of these patients were retrospectively analyzed.Results:The time from cSAH to the onset of acute cerebral infarction was 5-144 h, with median time of 2 d. The most common bleeding site of cSAH was the parietal lobe ( n=6); cSAH in the ipsilateral side of acute cerebral infarction was noted in 4 patients. Six patients had middle cerebral artery stenosis or occlusion, and 2 patients had anterior cerebral artery stenosis or occlusion. Hypertension ( n=7) was the most common primary disease; 7 patients were treated with antiplatelet drugs, anticoagulants and/or stents. The follow-up at 3 months after cSAH showed that 6 patients had good prognosis and one had poor prognosis. Conclusions:The cSAH often occurs 2 d after acute cerebral infarction; intracranial artery stenosis or occlusion may be the main cause of the disease. In patients complicated with cSAH, active antiplatelet, anticoagulation and/or stent therapy do not increase the risk of bleeding, and the prognosis is good.
