Abnormal origins of the vertebral artery with supra-aortic vessel variants are exceedingly uncommon. Herein, we present two cases of the vertebral artery originating from the right common carotid artery associated with the right subclavian artery arising separately as the initial branch of the aortic arch, followed by the right common carotid artery. We reviewed the embryology of the anomalous origins of the vertebral and subclavian arteries.

Intracranial xanthomas grow slowly, and clinical symptoms only appear when the mass compresses the surrounding tissues, so early diagnosis of the disease is difficult.
View Article and Find Full Text PDFBackground: It is hard to distinguish cerebral aneurysms from overlapping vessels in 2D digital subtraction angiography (DSA) images due to these images' lack of spatial information.
Objective: The aims of this study were to (1) construct a deep learning diagnostic system to improve the ability to detect posterior communicating artery aneurysms on 2D DSA images and (2) validate the efficiency of the deep learning diagnostic system in 2D DSA aneurysm detection.
Methods: We proposed a 2-stage detection system.
Objective: Chronic subdural hematoma (CSDH) is a common form of intracranial hemorrhage with a substantial recurrence rate. We aimed to investigate the predictive factors for the postsurgical recurrence of CSDH.
Methods: We retrospectively reviewed the medical records of patients with CSDH who underwent surgery in West China Hospital between January 2012 and June 2018.
Objective: To assess the current efficacy, safety, and risk factors of the Woven EndoBridge (WEB) in treating wide-neck intracranial aneurysms.
Methods: We searched the PubMed, Ovid MEDLINE, and Embase databases between December 1, 2012 and June 30, 2018. Studies were included if they featured ≥5 patients undergoing WEB for wide-neck intracranial aneurysms, reported an angiographic or clinical outcome and risk factors, and were published after December 1, 2012.
Objective: Little is known about the effectiveness of lumbar drainage (LD) in the treatment of delayed or recurrent cerebrospinal fluid (CSF) leaks. We report our institutional experience and the effectiveness of LD in the management of delayed or recurrent CSF leaks.
Methods: Between January 2014 and December 2018, a total 21 patients with delayed or recurrent CSF leaks were enrolled in the research.
Objective: The purpose of this study is to introduce our initial experience with the evaluation of the feasibility of using Willis covered stents (WCSs) in the treatment of complicated ophthalmic artery (OA) segment aneurysms.
Methods: Of the 162 patients with OA segment aneurysms treated by endovascular techniques in West China Hospital from January 2015 to August 2017, a total of 26 patients treated with WCSs were included in the study.
Results: Twenty-six patients with 26 aneurysms were included (mean age, 57.
Objective: The purpose of the present study was to introduce our initial experience with the use and feasibility of the Willis covered stent (WCS) in the treatment of blood blister-like aneurysms (BBAs) and to present a systematic review of the reported data on the treatment of BBAs with covered stents.
Methods: Fourteen consecutive patients with BBAs had been treated with WCSs at West China Hospital from January 2015 to August 2017. The patient medical records, angiographic findings, and endovascular treatment reports were reviewed by interventional neuroradiologists and neurosurgeons to obtain relevant clinical and angiographic information.
Background: The purpose of the present study was to describe our single-institutional experience of treating direct carotid-cavernous fistulas (DCCFs) with Willis covered stents (WCSs).
Methods: Of a total of 31 DCCFs, 10 were treated with WCSs (Microport, Shanghai, China) at West China Hospital from January 2015 to December 2016. The indications for treatment, perioperative findings, and postoperative and follow-up results were collected and analyzed.
Objective: The aim of this study was to identify potential prognostic factors of hemifacial spasm (HFS) after microvascular decompression (MVD), to establish the appropriate way to tackle postprocedure symptoms and complications (PPSCs), and to find the incidence and duration of PPSCs.
Methods: Two hundred and forty-eight patients with HFS were monitored between December 2009 and December 2014. The mean follow-up duration was 24 months (range, 6-67 months).
Unlabelled: In-stent stenosis after treated by Willis covered stent-case reports.
Background: Advancements in minimally invasive technology have allowed endovascular reconstruction of internal carotid aneurysm. However, in-stent stenosis is an important and well-characterized complication of stenting after the treatment of internal carotid aneurysm.
Prognosis research of delayed facial palsy after microvascular decompression for hemifacial spasm.
Acta Neurochir (Wien)
February 2016
Background: Although microvascular decompression (MVD) surgery has been widely accepted as an effective treatment for hemifacial spasm (HFS), delayed facial palsy (DFP) is not an unusual complication, but it has only been sporadically described in the literature. The purpose of this study was to examine the probability of occurrence, the risk/predisposing factors, and the prognosis and timing of DFP.
Methods: A prospective cohort study was conducted that included patients diagnosed with HFS and treated by MVD at our institution.
