BACKGROUND:: The prevalence of intracranial aneurysms is approximately 2% with an annual rupture rate of 0.7%. OBJECTIVE:: We describe our initial feasibility experience using a new double-lumen balloon catheter for single-catheter balloon-assisted coil embolization of wide-neck intracranial aneurysms. METHODS:: Two patients with large wide-neck intracranial aneurysms were referred for endovascular ...

BACKGROUND:: Incomplete coil occlusion is associated with increased risk of aneurysm recurrence. We hypothesize that intracranial stents can cause flow remodeling that promotes further occlusion of an incompletely coiled aneurysm. Objective: We studied our hypothesis by comparing the follow-up angiographic outcomes of stented versus non-stented incompletely coiled aneurysms. METHODS:: From ...

BACKGROUND: Pseudoaneurysms occur at the rupture site of true aneurysms and appear as irregularly shaped and partially thrombosed outpouchings of the main sac. Recanalization of thrombi inside pseudoaneurysmal sac is one of the putative mechanisms of rebleeding of unsecured aneurysms and of coil migration after endovascular treatment. We document "real ...

Abstract A 56-year-old woman presented with right-sided flank pain, dizziness, and nausea. Ultrasonography revealed hydronephrosis of the right kidney. CT showed a nodular mass at the ureteropelvic junction. Subsequent CT angiography revealed the nodular mass as a distal aneurysm of the right renal artery compromising the ureteropelvic junction. Selective diagnostic ...

INTRODUCTION: Dural arteriovenous fistulas involving marginal sinus are relatively rare. Transvenous embolization is a curative treatment of choice for them. Regional anatomy surrounding the marginal sinus comprises complex craniocervical bony structures and abundant venous interconnections. Therefore, dural arteriovenous fistulas involving marginal sinus may have various routes for a transvenous approach. ...

A 46-year-old woman presented with tetraplegia contrasting with a relatively preserved consciousness following aneurysmal subarachnoid hemorrhage (SAH). Multiple ischemic lesions were detected by magnetic resonance imaging (MRI), in the absence of vasospasm or signs of increased intracranial pressure. During the weeks before SAH, the patient had repeatedly used a nasal ...

Background Long-term follow-up studies after endovascular treatment for intracranial aneurysm are still rare and inconclusive. Parenchymal infarctions related to aneurysms have mostly been studied in patients with subarachnoidal hemorrhage (SAH) but infarction rates in patients with endovascularly treated unruptured aneurysms have been little studied. Purpose To determine the frequency of ...

The indications for endovascular coiling of intracranial aneurysms continue to expand. This is due, in part, to the development of intracranial specific stents which permit remodelling of complex aneurysm necks. While this approach has several advantages in the setting of unruptured aneurysms, certain challenges, in particular the requirement of concomitant ...

There have been significant advances in the technical aspects of endovascular therapy of cerebral aneurysms. Anterior communicating artery (Acom A) aneurysms were traditionally treated by surgical clipping. Endovascular coiling has the distinct advantage of being minimally invasive and can be performed anytime during the course of subarachnoid hemorrhage (SAH). To ...

Retrograde transfemoral artery catheterization is the most common way of implanting a percutaneous aortic valve. But in some cases, this access cannot be used and the subclavian artery access may represent an alternative to the femoral route, even offering certain advantages. This article describes prosthetic aortic valve implantation using the ...

Surgical repair of proximal right subclavian artery aneurysms can be difficult. They typically require a combined mediastinal exposure to control the innominate and right common carotid arteries and a supra- or infraclavicular exposure for distal control, with either a segmental resection and bypass or a bifurcated reconstruction. In this report, ...
