Angiographic Feature and Clinical Evaluation of the Anterior Falx Artery

摘要: The anterior falx artery which is a small meningeal branch of the ethmoidal from ophthalmic was described by Kuru (1967). Shiga(1968), Pollock and Newton (1968) reported anatomy, angiographic features some clinical evaluations this artery. In report, we shall demonstrate findings evaluation faix artery, based on thousand patients, or 1254 serial angiograms were taken between July, 1973 June, 1978. All these good quality. Through analysis material, following results obtained: visualized in 21% 217 normal cases 35% pathologic (Table 1). This 33.2% left carotid angiograms, but only 18.2% right angiograms. We also noticed that opacified more frequently side than other 2). Bilateral 221 patients 94(42%)showed arteries. eight cases, two different arteries demonstrated. Anterior important for collateral circulation moyamoya disease cerebral thrombosis. sometimes supplies meningioma, arterio-venous malformation tumors invading into dura. addition, it could be stressed there dilatation many with chronic subdural hematoma, subacute meningitis malignant leptomeningeal dissemination. These dilatations may due to compression bridging vein and/or circulatory change. Another feature change visualization same patient. 15 28 whom angiographies repeated, varied course one examination another. differences demonstrated preoperative postoperative tumor acute head injury. observations have convinced us often has significance.
