Abstract:
Objective To discuss the clinical manifestations, imaging data and DSA findings of lacunar infarction (LI). Methods One hundred and thirty-three patients, admitted to our hospital from May 2002 to April 2008, were chosen in our study; these patients with first onset as LI were confirmed by Head CT or MR; the clinical manifestations and imaging data were retrospectively analyzed; DSA was also performed on these patients and DSA findings were concluded. Results One hundred and thirty-three patients were clinically manifested as pure motor hemiplegia (PMH, n=42, 31.6%) and sensorimotor stroke (SMS, n=36, 27.1%). Two hundred and eighty-three lesions were noted by CT/MR examinations, including 78 locating at the endocyst (27.6%) and 121 locating at the corona radiate+greater oval center (91.0%). Forty-four patients were noted as having 101 intracranial vessel lesions by DSA, including 38 patients with angiostenosis, 6 with Moyamoya and 1 with single intracranial aneurysm; of the patients with angiostenosis, 95 lesions (34 in the offending vessels and 61 in other vessels) were found. Among the DSA (+) patients, PMH (n=21) and SMS (n=10) were mainly noted with their lesions locating at the endocyst (n=23) and the corona radiate+greater oval center (n=31); At least 1 high-risk factor such as hypertension, diabete, hyperlipemia, coronary heart disease and arial fibrillation was found in 44 patients. Conclusion The pathogeneses of LI are various. Main artery infarction may co-exist in some cases. PMH and SMS are common with their lesions frequently locating at basal ganglia area and corona radiate of the cerebral hemisphere. High risk factor exists in most patients with cerebrovascular diseases.
