[Juvenile cerebral infarction with familial hyperlipoproteinemia (a)--case report].
A 34-year-old male with a history of angina pectoris suddenly developed weakness in the right upper and lower limbs, and consulted our hospital. Computed tomography (CT) and magnetic resonance imaging (MRI) suggested cerebral infarction. Cerebral angiography revealed stenosis at the M1 portion of the left middle cerebral artery. Hypertension, diabetes, tobacco or hyperlipidemia were not considered as risk factors for cerebral infarction. The lipoprotein (a) [Lp(a)] level was high. In the present case, medication with a nicotinic acid agent, niceritrol, for hyperlipoproteinemia and low density lipoprotein (LDL) apheresis were performed. Concerning family history, the patient's mother and younger sister had hyperlipoproteinemia. Recent studies have reported that increased Lp(a) levels are an independent risk factor even in cerebral infarction and coronary artery disease. Measurement of Lp(a) levels and treatment for increased Lp (a) levels may be important.
