Summary of "Aneurysms of the Proximal (A1) Segment of the Anterior Cerebral Artery: A Clinical Analysis of 31 Cases."

This study aimed to investigate the characteristics of A1 aneurysms according to their locations and to compare their imaging appearances in order to identify factors associated with their rupture.

The Special Considerations in the Surgical Management of Proximal Anterior Cerebral Artery Aneurysms.

The proximal anterior cerebral artery (A1) aneurysms are difficult to clip because of their frequent proximity to perforators, location behind the parent artery, or adherence to surrounding structures...

Treatment of anterior cerebral artery and anterior communicating artery aneurysms with flow-diversion devices: a systematic review and meta-analysis.

To assess the early safety and efficacy of anterior cerebral artery (ACA) and anterior communicating artery (ACoA) aneurysm treatment with flow-diversion devices (FDDs), we performed a systematic revi...

Analysis of anterior cerebral artery tortuosity: association with anterior communicating artery aneurysm rupture.

Many researchers have found correlation between tortuous arteries and development of aneurysms in cerebral arteries. However, due to our knowledge, there are no studies analysing impact of tortuosity ...

Proximal middle cerebral artery aneurysms: microsurgical management and therapeutic results.

Management of proximal middle cerebral artery (M1) aneurysm can be challenging. Because of the diversity of aneurysm morphology and location of M1 aneurysms, the surgical strategy should be tailored f...

Medical and Biotech [MESH] Definitions

A polygonal anastomosis at the base of the brain formed by the internal carotid (CAROTID ARTERY, INTERNAL), proximal parts of the anterior, middle, and posterior cerebral arteries (ANTERIOR CEREBRAL ARTERY; MIDDLE CEREBRAL ARTERY; POSTERIOR CEREBRAL ARTERY), the anterior communicating artery and the posterior communicating arteries.

NECROSIS occurring in the ANTERIOR CEREBRAL ARTERY system, including branches such as Heubner's artery. These arteries supply blood to the medial and superior parts of the CEREBRAL HEMISPHERE, Infarction in the anterior cerebral artery usually results in sensory and motor impairment in the lower body.

Artery formed by the bifurcation of the internal carotid artery (CAROTID ARTERY, INTERNAL). Branches of the anterior cerebral artery supply the CAUDATE NUCLEUS; INTERNAL CAPSULE; PUTAMEN; SEPTAL NUCLEI; GYRUS CINGULI; and surfaces of the FRONTAL LOBE and PARIETAL LOBE.

Pathological conditions of intracranial ARTERIES supplying the CEREBRUM. These diseases often are due to abnormalities or pathological processes in the ANTERIOR CEREBRAL ARTERY; MIDDLE CEREBRAL ARTERY; and POSTERIOR CEREBRAL ARTERY.

NECROSIS occurring in the MIDDLE CEREBRAL ARTERY distribution system which brings blood to the entire lateral aspects of each CEREBRAL HEMISPHERE. Clinical signs include impaired cognition; APHASIA; AGRAPHIA; weak and numbness in the face and arms, contralaterally or bilaterally depending on the infarction.
