(2018) 128:1753–61. Multiple overlapping stents as monotherapy in the treatment of 'blister' pseudoaneurysms arising from the supraclinoid internal carotid artery: a single institution series and review of the literature. Surgical repair involves removal of the part of the carotid artery associated with the aneurysm, while endovascular stent grafting requires the use of catheters. Methods Three-dimensional morphological parameters obtained from CT angiography or … A bypass is then performed from the normal artery below the aneurysm to the normal artery above the aneurysm. A significant proportion of such aneurysms are now recognized to be caused by arterial dissection. Lifestyle changes to slow the progression of atherosclerosis. Brain.

Seventeen aneurysms in 16 patients occurred posttraumatically, secondary to motor vehicle accidents or surgical injury. Symptoms for carotid artery aneurysms may include transient ischemic attacks (TIAs) or stroke. The PCommA aneurysm is not visible because of the large anterior clinoid process (arrowhead) and the horizontal orientation of the internal carotid artery. An aneurysm in the carotid artery can progressively stretch and weaken an area of the wall, leading to a rupture of the artery. Surgery which required removal of the clinoid process was rather complex, and aneurysms within the cavernous segment were regarded by many as either unclippable or clippable given superb skill and acknowledgement of higher stakes.
