BACKGROUND AND PURPOSE Denser coil packing in intracranial aneurysms is believed to result in lower recanalization rates. Hydrogel-coated expandable coils (HydroCoil) improve volumetric packing of aneurysms in animal models and clinical studies, but data from large clinical series are limited. The objective of this retrospective analysis was to analyze immediate and follow-up angiographic resul...

BACKGROUND AND PURPOSE The use of stents in the setting of SAH is controversial because of concerns about the efficacy and risk of dual antiplatelet therapy. We compare complications of stent-assisted coil embolization in patients with acutely ruptured aneurysms with complications in patients with unruptured aneurysms. MATERIALS AND METHODS Between February 2007 and March 2015, 45 acutely rup...

BACKGROUND AND PURPOSE Even though endovascular coils have been widely used for the treatment of intracranial aneurysms, the cellular and molecular responses of aneurysms to the coils after embolization remain poorly understood. The aim of the present study was to understand the mechanism of apoptosis in aneurysms embolized with platinum coils in the rabbit model of elastase-induced aneurysms. ...

BACKGROUND AND PURPOSE The proportion of incompletely occluded aneurysms after coiling varies widely between studies. To assess overall outcome of coiling, we systematically reviewed the literature to determine initial occlusion, reopening, and retreatment rates of coiled aneurysms according to predefined criteria and subgroups. METHODS We searched PubMed and EMBASE (January 1999 to September...

True femoral artery aneurysm is a rare vascular entity and is often associated with aortic or peripheral aneurysms. Life-threatening complications associated with peripheral arterial aneurysms include rupture, thrombosis, and embolization. In patients with multiple aneurysms, any symptomatic aneurysms should be treated first; in asymptomatic patients, the aneurysms can be repaired either simult...

The posterior cerebral artery (PCA) is divided into 4 segments: precommunicating segment (P1), postcommunicating segment (P2), quadrigeminal segment (P3), and calcarine segment (P4). Small aneurysms are more prevalent than large aneurysms in patients with ruptured aneurysms. P2 and P3 aneurysms are usually managed by the subtemporal approach. This is a case report of rupture saccular aneurysm o...

True aneurysms of the profunda femoris artery are rare and are much less common than false aneurysms of this vessel. 1 Profunda artery aneurysms can affect either the main t runk of the artery or its branch~es. Unlike aneurysms of the common femoral artery they are frequently symptomatic. We report a case of bilateral synchronous profunda artery aneurysms. On one side the aneurysm was symptomat...

INTRODUCTION Aneurysmal subarachnoid hemorrhage (SAH) is a rare but devastating form of stroke. Endovascular therapy has been criticized for its higher rate of recanalization and retreatment. The safety and predictors of retreatment are unknown. We report the clinical outcomes, imaging outcomes and predictors for aneurysm retreatment after initial endovascular embolization. METHOD We identifi...

BACKGROUND AND PURPOSE Blister aneurysms of the supraclinoid ICA represent a rare but potentially catastrophic cause of SAH, often presenting both diagnostic and therapeutic dilemmas. We explore the utility of CTA in the identification and characterization of ICA blister aneurysms. MATERIALS AND METHODS We performed a retrospective review of catheter cerebral angiograms obtained at our instit...

In this communication, we studied whether 3D-CT angiography (3D CTA) gives us enough information for a safe operation without those from conventional catheter angiography (CCA) in patients with ruptured aneurysms. Between December 1996 and September 2005, we treated 162 consecutive patients with ruptured aneurysms in the acute stage based on 3D-CTA findings. One hundred sixty-two ruptured aneur...
