Ear ischemia induced by endovascular therapy for arteriovenous fistula of the sigmoid sinus: A case report.

Background: Arteriovenous fistula of the sigmoid sinus is an abnormal connection of arteries with the sigmoid sinus. Endovascular treatments of such lesions are considered safe and with low rates of complications.

Case Summary: A 62-year-old female patient underwent endovascular treatment of an arteriovenous fistula of the right sigmoid sinus on February 7, 2017, but her tinnitus was not cured.

Development and validation of an institutional nomogram for aiding aneurysm rupture risk stratification.

Rupture risk stratification is critical for incidentally detected intracranial aneurysms. Here we developed and validated an institutional nomogram to solve this issue. We reviewed the imaging and clinical databases for aneurysms from January 2015 to September 2018.

Prediction of Aneurysm Stability Using a Machine Learning Model Based on PyRadiomics-Derived Morphological Features.

Background and Purpose- Discrimination of the stability of intracranial aneurysms is critical for determining the treatment strategy, especially in small aneurysms. This study aims to evaluate the feasibility of applying machine learning for predicting aneurysm stability with radiomics-derived morphological features. Methods- Morphological features of 719 aneurysms were extracted from PyRadiomics, of which 420 aneurysms with Maximum3DDiameter ranging from 4 mm to 8 mm were enrolled for analysis.

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.
