BACKGROUND Anterior communicating artery complex is the most frequent site of intracranial aneurysms in most reported series. Anterior communicating artery aneurysms are the most complex aneurysms of the anterior circulation due to the angioarchitecture and flow dynamics of the ACoA region, frequent anatomical variations, deep interhemispheric location, and danger of severing the perforators wi...

The occurrence of familial cerebral aneurysms lends support to the importance of congenital factors in their pathogenesis. The information on the subject is, however, still meagre, there being less than 20 reports in literature. Earlier literature mentions the occurrence of cerebrovascular accidents in members of the same family with polycystic kidneys (Dunger, 1904). Tonnis and Lange-Cosack (1...

In order to obtain information about the relationship between variations in the circle of Willis and aneurysms, 44 complete circles of Willis with aneurysm were studied macroscopically. The incidence of variations was significantly higher in the aneurysm series than in the control circles without aneurysm. There was a definite correlation between asymmetric proximal segments of the anterior cer...

Neurological endovascular therapy (coiling) is nowadays presented as an excellent alternative to traditional clipping of cerebral aneurysms. Take into account this, the purpose of this article is to report 10 cases of ruptured aneurysms in the anterior communicating artery and that have been treated endovascularly in a tertiary Care Center in Tunja / Colombia from November 1, 2015 to September ...

The anterior communicating artery was studied with the operating microscope in 10 autopsy cases. This vessel was present in all cases with reduplication in three. Arterial diameter ranged from 0.8 to 2.3 mm, with lengths of 5 to 10 mm. Branches of the anterior communicating artery were found in every case (range 3-13, average 5.4). Most branches were small (50-250 mu), but at least one large br...

BACKGROUND The management of cerebral aneurysms requires a significant level of expertise, and large areas of the country have limited access to such advanced neurosurgical care. The objective of this study was to examine the impact of longer travel distance on aneurysm management. METHODS Adult patients treated for cerebral aneurysms from January 1, 2013 to January 1, 2016, were retrospectiv...

Anterior communicating artery (ACoA) aneurysms have a complex architecture and many variations, making endovascular therapy more difficult in some cases. The aim of this study was to investigate whether the neck position of an aneurysm was identifiable for determining the immediate angiographic success and procedural complications in the coiling of the ACoA aneurysms. We conducted a retrospecti...
