Charcot Bouchard Aneurysm

摘要: Charcot-Bouchard aneurysms are minute (microaneurysms) in the brain that occur small penetrating blood vessels with a diameter is less than 300 micrometers. The most common involved lenticulostriate branches (LSA) of middle cerebral artery (MCA). LSAs originate from MCA just before its bifurcation, and they can vary between 2 to 12 number (average 8.1). Most arise medially (99.2%), close internal carotid artery. They supply basal ganglia, more specifically putamen caudate, followed by thalamus, pons, cerebellum. named after French physicians Jean-Martin Charcot his student Charles Joseph Bouchard. In 19th century, Bouchard discovered these during research under Charcot. Cole Yates strengthened Bouchard's work demonstrating truly exist using microangiographic techniques 1960s. However, it has been topic lively debated if is, fact, rupture responsible for intracerebral bleeds.Individuals chronic systemic hypertension at high risk developing atrophy outer muscular layer. With loss integrity vessel wall, microaneurysms develop LSA, which rupture. Bleeding into deep structures parenchyma also referred as intraparenchymal hemorrhage or, broadly, hemorrhage. Clinically deficits present point towards location bleed. first line diagnostic modality patients non-contrast computed tomography (CT) head visualize Depending on severity treatment options observation neurosurgical intervention.
