"Whiplash" cervical trauma with fracture and migration of carotid stent fragments.

Background: Angioplasty using a carotid stent is a treatment modality for carotid stenosis, with results similar to those obtained with endarterectomy, as demonstrated by important studies. The increasing use of this procedure has also led to a larger number of reports of complications, stent fractures among those. Stent fracture is a rare manifestation and hence needs further studying so that its actual prevalence can be determined, as well as its associated risk factors and proper clinical management.

Endovascular treatment of carotid-cavernous vascular lesions.

Objective:: to evaluate the endovascular treatment of vascular lesions of the cavernous segment of the internal carotidartery (ICA) performed at our institution.

Methods:: we conducted a descriptive, retrospective and prospective study of patients with aneurysms of the cavernous portion of the ICA or with direct carotid-cavernous fistulas (dCCF) undergoing endovascular treatment.

Results:: we included 26 patients with intracavernous aneurysms and ten with dCCF.

Treatment of complex intracranial aneurysm: Case report of the simultaneous use of endovascular and microsurgical techniques.

Background: The surgical treatment of complex intracranial aneurysms (CIAs) represents a significant challenge to the skill and expertise of the neurosurgeon. The natural history of complex cerebrovascular lesions is especially unfavorable because of the pressure effect on adjacent areas, the risk of embolism in the presence of intraluminal thrombi, and the possibility of hemorrhage through leakage or rupture of the aneurysm. The surgical strategy must be customized for each case in order to maximize the treatment effectiveness and the safety of the patient.

Advances in the endovascular treatment of direct carotid-cavernous fistulas.

Carotid cavernous fistulas (CCFs) are abnormal connections between the carotid artery and the cavernous sinus. They are considered direct when there is a direct connection between the internal carotid artery and the cavernous sinus. These cases are generally traumatic.

Giant fusiform aneurysm arising from fenestrated posterior cerebral artery and basilar tip variation: case report.

Objective: A giant fusiform aneurysm in the posterior cerebral artery (PCA) is rare, as is fenestration of the PCA and basilar apex variation. We describe the angiographic and surgical findings of a giant fusiform aneurysm in the P1-P2 PCA segment associated with PCA bilateral fenestration and superior cerebellar artery double origin.

Clinical Presentation: A 26-year-old woman presented with a 2-month history of visual blurring.
