Background: Foramen magnum dural arteriovenous fistulas (DAVF) with perimedullary venous drainage represent a small minority of intracranial DAVF, and only a number of small series with limited cases have been reported. The purpose of this retrospective study is to summarize experience of transarterial Onyx embolisation in the treatment of these lesions, with emphasis on the balloon-augmented technique.
Background: Vascular reconstructions are the established treatment for ischemic cerebrovascular disease. Cerebral hyperperfusion syndrome (CHS) is occasionally seen after vascular reconstruction and manifest clinical symptoms. The purpose of this study is to investigate the incidence and clinical features of CHS after vascular reconstruction.
BACKGROUND AND PURPOSE: Recently some series have been published about the use of Onyx for the treatment of DAFVs with satisfactory results. Our aim was to describe the treatment of different types of intracranial DAVFs with transcatheter injection of Onyx through an arterial approach.
Objective: To report our experience in carotid artery stenting (CAS) with GORE flow reversal system®, focusing the assessment of its efficacy, security and practice procedure evolution.
Objective: To present the author s experience with a direct transcervical or transbrachial puncture approach in neuroendovascular procedures in which cranial access via the commonly used percutaneous transfemoral route was impossible because of tortuous upstream angioarchitecture.
SUMMARY: In this short report, we describe the potential contribution of SWI in the noninvasive evaluation of DAVFs. SWI images were compared with DSA for the identification of the location of the fistulous point, the presence of CVR, and the presence of the PPP. In 5 of 6 patients, it was possible to identify the fistulous locations depicted as hyperintensity within venous structures. Cortical venous reflux was underestimated on SWI in 3 cases of robust CVR and not identified in 2 cases of less severe CVR. The PPP seen on angiograms correlated anatomically with increased number, caliber, and tortuosity of hypointense veins seen on SWI. Furthermore, SWI was superior to conventional MR imaging in the detection of these dilated veins. These preliminary results suggest an important role for SWI in the detection and assessment of the complex hemodynamics associated with DAVFs.
BACKGROUND AND PURPOSE: The endosaccular occlusion by using BPC has been useful in the treatment of intracranial aneurysms, but its limited durability remains a deep-seated drawback. The Matrix2 coil, one of the bioactive-coated coils, had been developed to improve this limited durability. To evaluate durability of Matrix2 coils after embolization of intracranial aneurysms, we retrospectively compared 1-year outcomes with that of BPC groups.
Background: Indirect carotid-cavernous fistulae are dural arteriovenous shunts between dural branches of the internal and/or external carotid arteries and the cavernous sinuses.
SUMMARY: The balloon remodeling technique was initially designed for the endovascular treatment of anatomically complex aneurysms, specifically wide-neck aneurysms. A nondetachable balloon is inflated in front of the aneurysm neck during coil deposition and removed at the end of the procedure. Some controversies regarding the safety of the technique were introduced by the recent publication of a series showing a much higher rate of complications with the remodeling technique compared with the standard coiling technique. However, recent data from the literature review and from the large ATENA and CLARITY series show that the safety of standard coiling and remodeling is quite similar. Anatomic results are also probably better after remodeling. Finally, due to equivalent safety and better anatomic results, the remodeling technique can be widely used in the management of both ruptured and unruptured aneurysms.
BACKGROUND AND PURPOSE: Various modifications of detachable coils have been attempted to reduce recurrence rates in aneurysmal coil embolization and HydroSoft coil is one of them. The authors report their experience using HydroSoft coils in the treatment of cerebral aneurysms.
Objectives The objective of this study was to compare the cerebral embolic load of filter-protected versus proximal balloon–protected carotid artery stenting (CAS).
Background: Percutaneous balloon rhizotomy is one of the standard techniques for the treatment of trigeminal neuralgia. However, there have been well-reported complications from cannulating the foramen ovale (FO). We describe a novel technique for cannulating the FO using 3-dimensional (3D) rotational fluoroscopy.
BACKGROUND AND PURPOSE: Many authors have reported the increase in vertebral body height after vertebroplasty. However, McKiernan et al demonstrated dynamic mobility in patients who underwent vertebroplasty and concluded that any article that claims vertebral height restoration must control for the dynamic mobility of fractured vertebrae. The purpose of this study was to compare prevertebroplasty (supine cross-table with a bolster beneath) with postvertebroplasty vertebral body height to find out whether vertebroplasty itself really increases the vertebral height.
BACKGROUND AND PURPOSE: An infrequent occurrence during endovascular treatment is protusion of detachable coils into the parent lumen with a subsequent thrombosis within in the parent vessel or embolic events. We report the short- and intermediate-term angiographic and clinical outcomes of patients who experience coil or loop protrusions and are managed with medical or additional endovascular treatments.
SUMMARY: Intracranial dissecting aneurysms constitute rare lesions with complex management and elevated morbidity and mortality. Results of 23 patients harboring such lesions treated with the PED are reported. Standard dual antiplatelet therapy was instituted. Neurologic and angiographic assessments were obtained at 3, 6, and 12 months. Clinical presentation included SAH (52%), symptoms of mass effect (22%), ischemia (4%), and incidental finding (22%). The posterior circulation was affected in 91% of cases. Total occlusion was demonstrated in 69.5% of patients, with an increment to 87.5% considering only patients with at least 3 months of follow-up. Small aneurysms demonstrated higher rates of total occlusion (6/7) compared with large (5/7) and giant (5/9) ones. Good clinical outcome was achieved in 74% of patients. Reconstructive endovascular treatment of intracranial dissecting aneurysms with the PED provided good clinical and angiographic results with acceptable risks, representing an attractive therapeutic option for this complex disease, especially when parent vessel preservation is mandatory.
