Spontaneous dissecting aneurysms of anterior and middle cerebral artery associated with brain infarction

Intracranial Fusiform Aneurysms: It's Pathogenesis, Clinical Characteristics and Managements

“…However, the classic dissecting aneurysm also has a fusiform appearance 23) and several authors have recently reported the presence of fusiform aneurysms caused by dissection [2][3][4][5][6][9][10][11]13,16,17,21,23,24,26,34) . Therefore, all cases of fusiform aneurysms based on external view without Intracranial Fusiform Aneurysm｜SH Park, et al…”

“…Fusiform aneurysms in this study were found in the anterior circulation in 17 (77%) of the patients and in the posterior circulation in 23%. Dissection has been proposed as the main underlying cause of fusiform aneurysms and most commonly involves the posterior circulation, especially vertebral and basilar arteries 1,3,[5][6][7][8][9][10]15,16,19,20,[24][25][26]32,35) However, typical cases of dissecting aneurysm in the posterior circulation were excluded in this study. Dissecting aneurysms can originate in any regions of the anterior circulation, such as the ICA 1,29) , MCA 2,4,6,10,[13][14][15][16]22,26,30) , the ACA 3,10,[16][17][18]24,27,30,32,35) and rarely in the anterior choroidal artery 21) .…”

“…However, Kurino et al 16) reported a patient with a dissecting aneurysm in the MCA who presented with ischemic symptoms and who showed a poor outcome after conservative treatment. They recommend surgical revascularization distal to the compromised artery.…”

Ischemic Stroke Due to Dissection of the Middle Cerebral Artery Treated by Superficial Temporal Artery-Middle Cerebral Artery Anastomosis-Case Report-

“…4,8,11,17) Angiographic demonstration of an intimal flap, false lumen, or pseudoaneurysm is relatively uncommon.…”

“…Dissection of the MCA short time. 8) Although surgical treatment such as wrapping, coating, or trapping may be appropriate in the presence of SAH, the treatment for ischemic symptoms remains controversial since subsequent bleeding often leads to poor outcomes. Extensive lesions of dissection seen on angiography have resulted in a wide range of cerebral infarction and poor prognosis.…”
