Enhanced T-cell activation and chemokine-associated function in CD14-positive cells from venous sinus blood in sub-acute cerebral venous sinus thrombosis.

Background: Patients with sub-acute cerebral venous sinus thrombosis experience (SA.CVST) severe symptoms compared to two other venous sinus-related diseases, including chronic cerebral venous sinus thrombosis (C.CVST) and idiopathic intracranial hypertension (IIH).

High-resolution magnetic resonance imaging-based radiomic features aid in selecting endovascular candidates among patients with cerebral venous sinus thrombosis.

Objectives: Cerebral venous sinus thrombosis (CVST) can cause sinus obstruction and stenosis, with potentially fatal consequences. High-resolution magnetic resonance imaging (HRMRI) can diagnose CVST qualitatively, although quantitative screening methods are lacking for patients refractory to anticoagulation therapy and who may benefit from endovascular treatment (EVT). Thus, in this study, we used radiomic features (RFs) extracted from HRMRI to build machine learning models to predict response to drug therapy and determine the appropriateness of EVT.

Endovascular Treatment of the Huge Dissecting Aneurysms Involving the Basilar Artery by the Internal Trapping Technique: Technical Note.

Background: The endovascular strategy of the huge dissecting aneurysms involving the basilar artery (BA) is controversial and challenging. This study was to investigate the clinical and angiographic outcomes of the treatment of the huge dissecting aneurysms involving the BA by the internal trapping (IT) technique.

Methods: We retrospectively studied 15 patients with the huge dissecting aneurysms involving the BA treated by the IT technique between September 2005 and September 2014 in Department of Interventional Neuroradiology of Beijing Tiantan Hospital.

Clinical effectiveness of preoperative embolization for cerebellar hemangioblastoma.

The cerebellar hemangioblastoma (CHB) has an abundant blood supply and deep anatomical location. Complete surgical resection is generally very difficult. This study investigated the safety and effectiveness of preoperative embolization followed by surgical resection of CHB in a large cohort of patients.

[Multiple factors related with intracranial hemorrhage of dural arteriovenous fistula: clinical analysis].

Objective: To discuss the relevant predicative factors of dural arteriovenous fistula (dAVF) in intracranial hemorrhage.

Methods: A total of 144 consecutive patients with dAVFs were recruited for a retrospective analysis from 1996 to 2006. The relevant factors of gender, age, fistula flow rate, arterial supply, lesion and venous drainage pattern were analyzed to evaluate the outcome of intracranial hemorrhage.

Transvenous embolization with a combination of detachable coils and Onyx for a complicated cavernous dural arteriovenous fistula.

Background: Treatment of cavernous dural arteriovenous fistulas (DAVF) is usually made by a transarterial approach. However, in many complicated patients, treatments via transarterial approaches can not be achieved, and only an operation via a transvenous approach is feasible. We aimed to study the feasibility of transarterial embolization of cavernous dural arteriovenous fistulas with a combination detachable coils and Onyx to embolize a complicated cavernous DAVF via a transvenous approach.

Transvenous embolization of cavernous dural arteriovenous fistula: report of 28 cases.

Background: Usually, cavernous dural arteriovenous fistula can be treated via transarterial approaches. However, in many complicated patients, transvenous approaches are superior to the transarterial ones because of the difficulties during a transarterial operation. In this study, we retrospectively analyzed the outcomes of 28 patients with cavernous dural arteriovenous fistula treated by transvenous embolization.

[Endovascular treatment of posterior cerebral artery aneurysm: analysis of 21 patients].

Objective: To investigate the effect of endovascular treatment on posterior cerebral artery (PCA) aneurysm.

Methods: The clinical data of 21 patients with PCA aneurysm, 12 males and 9 females, aged 3 - 60, totally 22 aneurysms, 3 located in the P1 segment, 16 (in 15 patients) on the P2 segment, and 3 being serpentine aneurysms and involving P2-3 segment, were analyzed. One patients gave up treatment, 6 patients, with 7 aneurysms, underwent aneurysm sac occlusion, and 14 patients underwent parent vessel occlusion.

[Transvenous embolization in treatment of refractory carotid-cavernous sinus fistula].

Objective: To investigate the effects of transvenous embolization in treatment of refractory carotid-cavernous sinus fistula (CCF).

Methods: Twenty-five patients of refractory CCF with 28 foci underwent transvenous embolization, femoral vein-inferior petrosal sinus approach was used in 12 of which, and femoral vein-facial vein-superior ophthalmic vein approach was used in 12 of which. The embolizing materials included controllable coils (GDC, EDC), free coil, and silk.

[Endovascular stent implantation in treatment of intracranial wide-necked aneurysms].

Objective: To evaluate the effectiveness and feasibility of treatment of intracranial wide-necked aneurysms with a new technique of Neuroform self-expanding stent combined with detachable coil.

Methods: A retrospective analysis of thirty patients with intracranial wide-necked aneurysms, 14 males and 16 females, aged 48 (18-68), wide-necked aneurysms, underwent occlusion of aneurysms using Neuroform self-expanding stent combined with detachable coil.

Results: 21 of the 30 aneurysms were completely occluded (70%) and 9 of the 30 aneurysms were incompletely occluded (30%) after initial coils embolization.

Endovascular treatment of cerebral arteriovenous malformations with Onyx embolization.

Background: In the past 5 years, new treatment materials and techniques offering a different concept in endovascular treatment have been described for cerebral arteriovenous malformations (CAVMs). The aim of this study was to assess the endovascular treatment of CAVMs by using a liquid embolic material, Onyx (Micro Therapeutics. Inc.

[Transvenous occlusion of carotid cavernous fistula].

Objective: To evaluate the treatment of carotid cavernous fistula with the transvenous approaches.

Methods: Seventeen patients (14 males and 3 males) with carotid cavernous fistula (CCF) were retrospectively analyzed.

Results: Totally 18 cavernous sinus of 17 patients were occluded.
