BACKGROUND AND PURPOSE Spinal cord AVMs represent rare and insufficiently studied pathologic entities. Embolization is thought to play an important role in the management of spinal cord AVMs. Factors for recurrent hemorrhage and the impact of endovascular treatment on prevention of recurrent hemorrhage remain to be confirmed. We aimed to assess recurrent hemorrhagic incidence of spinal cord AVM...

BACKGROUND AND PURPOSE The advent of modern neuroendovascular techniques has highlighted the need for a simple, effective, and reliable brain arteriovenous malformation endovascular grading scale. A novel scale of this type has recently been described. It incorporates the number of feeding arteries, eloquence, and the presence of an arteriovenous fistula component. Our aim is to assess the vali...

background: management of intracranial aneurysms has made debates about the best treatment modality in recent years. the aim of this study was to compare the interventional outcomes between two groups of patients, one treated with endovascular coiling and the other treated with surgical clipping. methods: this prospective study included 48 patients with intracranial aneurysms who underwent endo...

Objective : The authors present the result of endovascular treatment in cases of residual or recurrent cerebral aneurysms after surgery. Methods : 370 cases harboring 410 aneurysms underwent endovascular coil embolization over the past eight years. We selected 13 cases that underwent coil embolization in the post-surgical condition with residual or recurrent aneurysms. Radiologic and clinical d...

background: coarctation of the aorta (coa) is a defect that accounts for 5-8% of all congenital heart diseases. balloon angioplasty as a treatment for coa is increasingly performed, with endovascular stents having been proposed as a means of improving the efficacy and safety of the procedure. the aim of this study was to evaluate the systolic blood pressure gradient at rest and during maximal e...

The treatment of acute ischemic stroke (AIS) in the setting of intracranial large artery occlusion (LAO) with intravenous tissue plasminogen activator (IV-tPA) is associated with low rates of recanalization and high rates of neurological morbidity and functional dependence. Endovascular intervention, particularly mechanical thrombectomy, is a promising therapeutic adjunct to IV-tPA for the trea...

OBJECTIVES The true giant splenic artery aneurysms are extremely rare and can be fatal. Although surgical approach has been the standard of care in the past, endovascular methods gained more importance in recent years. BACKGROUND We describe a case with true giant splenic artery aneurysm, treated with endovascular approach. METHODS A 68-year-old female patient with abdominal pain admitted t...

Endovascular treatment thirty-three after the first published report on angioplasty, continues to be a rapidly evolving field for the treatment of patients with peripheral arterial disease. A multitude of studies detailing technical improvements and innovative developments have been published. The morphology of a lesion may have an influence on the technical outcome, results at follow up and al...

OBJECTIVE The aim of this study was to describe our early experience in the treatment of ruptured abdominal aortic aneurysms with bifurcated endografts. We report on our initial twelve-month experience using this approach. METHODS Clinical data on patients with ruptured abdominal aortic aneurysms treated at a single tertiary center in Brazil were prospectively recorded. The eligibility for en...

In recent years, technical developments have made endovascular procedures attractive therapeutic options and enabled the endovascular surgeon to redefine the management of cerebral aneurysms. However, as the number of aneurysms undergoing endovascular therapy has grown, so has the number of patients with incompletely treated aneurysms who are presenting for further management. In cases of failu...
