Lacunar Infarction Caused by Chronic Subdural Hematoma

摘要: In chronic subdural hematoma (CSDH) patients, motor functions usually recover quickly after burr-hole surgery; however, in a rare case, the hemiparesis showed poor improvement surgery. that investigation of cerebral infarctions is important. Among 284 CSDH patients with weakness, magnetic resonance image (MRI) and MR angiography (MRA) were acquired 82 before surgery when progressed rapidly. Small lacunar infarction was identified on side five cases; all older than 80 years hypertension, diabetes mellitus had been diagnosed two. (100%), MRA demonstrated downward or upward shift M1 portion middle artery side, where perforating arteries originate. Conversely, only 4 (5.2%) without shift. The risk factors high detected distortion, twisting, elongation lenticulostriate might be cause infarctions, rather formation lipohyalinosis microatheroma arteries. Therefore, anti-platelet treatment not necessary for CSDH-inducing infarction. caused by small, patients' mild, prognosis good, they recovered well from weakness physical rehabilitation. examinations are recommended especially patient complains sudden onset rapid deterioration weakness.
