What is a bifurcation aneurysm?
Bifurcation aneurysms were defined as lesions originating from major bifurcations,5 including the anterior cerebral artery (ACA), anterior communicating artery (ACoA), posterior communicating artery (PCoA), internal carotid artery (ICA), middle cerebral artery (MCA), and top of the basilar artery (TOBA).
What is ICA bifurcation aneurysm?
Internal carotid artery (ICA) bifurcation aneurysms are rare and easily bleed in younger patients, but are difficult to treat surgically, due to perforators surrounding and adherent to the aneurysm. A series of 25 patients treated by clipping under the operating microscope are analyzed and compared with previous cases.
How serious is a carotid aneurysm?
These symptoms can vary, depending upon what is compressed, but may include facial swelling, hoarseness or difficulty swallowing. Rarely, carotid artery aneurysms can rupture, or burst, which is a life-threatening problem.
What is a wide neck bifurcation aneurysm?
Wide neck bifurcation aneurysms (WNBAs) are among the most difficult saccular aneurysms (with large and giant aneurysms) to treat by a surgical or endovascular approach.1 Since aneurysm coiling was introduced, endovascular treatment (EVT) of WNBAs has been challenging for several reasons: (1) neck width makes it …
What is high carotid bifurcation?
The carotid bifurcation is the point at which the common carotid artery terminates. As it does so, it forms the internal and external carotid arteries which go on to supply the head and neck. The height of the carotid bifurcation is noted to be highly variable in the literature.
What is carotid artery bifurcation disease?
The internal carotid arteries supply blood to the brain. The most common location of atherosclerotic plaque buildup is the carotid bifurcation (Fig. 1), where the common carotid divides into the internal and external carotid arteries.
What is a neck aneurysm?
An extracranial carotid artery aneurysm is a bulging or ballooning in the wall of the carotid artery in the neck.
What is dome-to-neck ratio?
Finally, the (1) dome-to-neck ratio (maximum dome width/maximum neck width) and (2) aspect ratio (dome height/maximum neck width) were calculated to measure the neck size of the aneurysms.
Where are 85% of aneurysms located?
In the brain, the most common location for an aneurysm is along the vascular tree at the base of the brain, called the Circle of Willis. Appropriately 85% of cerebral aneurysms are found in the anterior portion of the Circle, most commonly where the arteries bifurcate or divide.
What is treatment for iliac artery aneurysm?
The diagnostic procedures used for an iliac aneurysm include an ultrasound or CT scan. If one is found, surgery is usually the recommended treatment. Stenting, the use of small stents surgically implanted to reinforce the artery wall, is usually the preferred method.
What treatment is required for a carotid artery aneurysm?
The mainstay of treatment of extracranial carotid artery aneurysms is surgical repair. The surgical repair entails the resection of that portion of the carotid artery that is involved with the aneurysm. A bypass is then performed from the normal artery below the aneurysm to the normal artery above the aneurysm.
What are the symptoms of carotid artery aneurysm?
Stroke or transient ischemic attacks are possible symptoms of carotid artery aneurysms, notes Cleveland Clinic. In some patients, an aneurysm leads to clots that obstruct blood flow to the brain, requiring immediate treatment. Other potential symptoms include swallowing trouble, hoarseness or facial swelling.
