BACKGROUND AND PURPOSE Large and giant intracranial aneurysms are increasingly treated with endovascular techniques. The goal of this study was to retrospectively analyze the complications and long-term results of coiling in large and giant aneurysms (≥ 10 mm) and identify predictors of outcome. MATERIALS AND METHODS A total of 334 large or giant aneurysms (≥ 10 mm) were coiled in our institu...

MATERIALS AND METHODS: Hospitalizations for clipping or coiling of unruptured cerebral aneurysms from 2001 to 2008 were identified by cross-matching ICD codes for the diagnosis of unruptured aneurysm (437.3) with procedural codes for clipping (39.51) or coiling (39.52, 39.79, or 39.72) of cerebral aneurysms and excluding all patients with a diagnosis of subarachnoid hemorrhage (430) and intrace...

BACKGROUND AND PURPOSE Partially thrombosed aneurysms as a distinct entity form a diverse collection of complex aneurysms characterized by organized intraluminal thrombus and solid mass. Endovascular treatment options are PVO or selective coil occlusion of the remaining lumen. We present long-term clinical and angiographic results of endovascular treatment of unruptured partially thrombosed ane...

BACKGROUND Endosaccular coiling, vessel occlusion, stenting, stent-assisted coiling, and flow diversion are all endovascular treatment options for pseudoaneurysms (PAs) of the head and neck. We explore different clinical situations in which these were selected for PA management at a single institution. METHODS Over a period of ten years, 33 patients presented to our hospital with PAs of the h...

BACKGROUND AND PURPOSE Endovascular treatment has increasingly been used for aneurismal subarachnoid aneurismal hemorrhage. The aim of this analysis is to assess the current evidence regarding safety and efficiency of clipping compared with coiling. METHODS We conducted a meta-analysis of studies that compared clipping with coiling between January 1999 and July 2012. Comparison of binary outc...

OBJECTIVE Although endovascular coiling has been used for 15 years in the treatment of intracranial aneurysms, fewer than 60 published studies have directly compared microsurgical clipping and endovascular coiling, and only two studies have used a randomized, prospective design. The objective of this review is to weigh evidence for the efficacy of endovascular coiling compared with microsurgica...

BACKGROUND AND PURPOSE The relative merits of treating ruptured aneurysms with clipping versus coiling continue to be a topic of debate. We evaluated a national, multihospital patient data base to examine recent trends in ruptured aneurysm therapies and to compare peri-procedural outcomes between clipping and coiling treatments. MATERIALS AND METHODS The Premier Perspective data base was used...

OBJECTIVE The International Cooperative Study on the Timing of Aneurysm Surgery demonstrated that subarachnoid hemorrhage (SAH) patients who underwent surgery on post-hemorrhage days 4-10 had worse outcomes than patients treated on days 0-3 and days 11-14. Based on these findings, it was concluded that patients who present with SAH on days 4-10 should have aneurysm surgery delayed until after d...

BACKGROUND AND PURPOSE Stent-assisted coiling of intracranial aneurysms requires antiplatelet therapy, typically aspirin and clopidogrel to prevent thromboembolic complications. There is a substantial concern that tirofiban may increase the risk of hemorrhage when used as an antiplatelet premedication in ruptured intracranial aneurysms. Our aim was to evaluate the safety and efficacy of intrave...

Nematodes of three genera (Acrobeloides sp., Aphelenchus avenae, and Scutellonema brachyurum) were induced to coil and enter anhydrobiosis in drying soil of two types: sandy loam and loamy sand. Coiling was studied in relationship to soil moisture characteristics. Coiling and the physiological state of anhydrobiosis occurred before the water in sandy soils reached a water potential of -15 bars....
