Anatomical Features of Middle Cerebral Artery Bifurcations and those with Aneurysms
To elucidate the anatomical differences between patients with normal MCA bifurcations and those with bifurcations harboring MCA aneurysms, the analysis of three dimensional MRA or DSA were performed. Sixty two patients without intracranial lesions underwent three-dimensional MRA. The width of M2 branches and lateral angles, were measured. Then the DA ratios (width of larger M2/width of smaller ...
متن کاملDistal anterior cerebral artery mirror aneurysms and middle cerebral artery aneurysms.
A 52-year-old woman presented with bilateral distal anterior cerebral artery (ACA) mirror aneurysms, in addition to two right middle cerebral artery (MCA) aneurysms. The left distal ACA and right MCA aneurysms were clipped through right interhemispheric and right pterional craniotomies. The right distal ACA aneurysm was thrombosed. Distal ACA aneurysms tend to be multiple, but mirror aneurysms ...
متن کاملA New Classification Of Unruptured Middle Cerebral Artery Bifurcation Aneurysms
MCA aneurysms comprise 20% to 25% of intracranial aneurysms.Majority of middle cerebral artery aneurysms are treated with microsurgical clipping. Most of the classifications are based on size, location or pathology which are effective for description but are less useful in preoperative planning and also in deciding the technique or type of clip application. The aim of our study was to study the...
متن کاملThe transsylvian approach to middle cerebral artery bifurcation/trifurcation aneurysms.
A transsylvian approach to treat aneurysms located at the bifurcation/trifurcation of the middle cerebral artery (MCA) is described. This surgical route traces a distal MCA branch retrogradely into the Sylvian fissure whereupon a secondary MCA branch and the main stem of the MCA (M1) are identified before aneurysm clipping. The advantages, and disadvantages of this approach are discussed. The t...
متن کاملEndovascular management of giant middle cerebral artery aneurysms.
BACKGROUND This article reported the experience of endovascular treatment in giant middle cerebral artery (MCA) aneurysms with parent artery occlusion or stent-assisted coiling. MATERIAL AND METHODS Eleven consecutive patients with giant MCA aneurysms were included. The aneurysms predominantly involved the M1 segment in two cases, bifurcation in four cases, and M2 in five cases. Four M2 fusif...
