Dissection-related carotid-cavernous fistula (CCF) following surgical revascularization of chronic internal carotid artery occlusion: a new subtype of CCF and proposed management.

Background: The development of carotid-cavernous fistulas (CCFs) during surgical recanalization of chronic internal carotid artery occlusion (ICAO) may be secondary to severe ICA dissection rather than a focal tear of the cavernous ICA seen in typical traumatic CCFs. The purpose of this study is to investigate the causal relationship between the CCFs and severe ICA dissections and to characterize technical outcomes after treatment with stenting.

Methods: Five patients underwent treatment with self-expanding stents due to intraprocedural CCF and ICA dissection following surgical removal of ICAO plaque.

Difference in Angiographic Characteristics Between Hemorrhagic And Nonhemorrhagic Hemispheres Associated with Hemorrhage Risk of Moyamoya Disease in Adults: A Self-Controlled Study.

Background: Here, we compare the angiographic characteristics of hemorrhagic and nonhemorrhagic hemispheres within the same adult patient with moyamoya disease (MMD) and identify the possible risk factors for initial and recurrent hemorrhage during the long-term follow-up period.

Methods: We retrospectively collected and analyzed the clinical and angiographic data of 145 consecutive adults with hemorrhagic MMD between 2004 and 2011. Separate angiographic characteristics of the hemorrhagic and nonhemorrhagic hemispheres were analyzed based on digital subtraction angiography.

Intracranial Aneurysms Associated with Moyamoya Disease in Children: Clinical Features and Long-Term Surgical Outcome.

Background: Moyamoya disease (MMD) in children was rarely associated with intracranial aneurysms. The purpose of this study was to report the clinical characteristics and long-term surgical outcomes of pediatric intracranial aneurysms accompanied with MMD.

Methods: Between October 2002 and October 2013, our department treated 9 pediatric MMD patients (aged ≤17 years) with intracranial aneurysms.

Hemorrhagic Moyamoya Disease in Children: Clinical, Angiographic features, and Long-Term Surgical Outcome.

Background And Purpose: Here, we describe the clinical, angiographic characteristics, and long-term surgical outcome of hemorrhagic moyamoya disease in children.

Methods: We retrospectively collected 374 consecutive children with moyamoya disease (hemorrhagic 30 and ischemic 344) between 2004 and 2012 in our hospital. The clinical and radiological characteristics of the hemorrhagic patients were retrospectively described and analyzed.

A complex cavernous sinus dural arteriovenous fistula secondary to covered stent placement for a traumatic carotid artery-cavernous sinus fistula: case report.

Authors present the case of a patient with a direct carotid artery-cavernous sinus fistula caused by head trauma in whom a self-expanding covered stent was successfully used to obliterate the fistula. However, at the 9-month follow-up an angiogram revealed a complex caroticocavernous fistula that was completely obliterated with Onyx 18 transarterially.
