Rescue N-butyl-2 cyanoacrylate embolectomy using a Solitaire FR device after venous glue migration during arteriovenous malformation embolization: technical note.

One of the procedural risks in arteriovenous malformation (AVM) embolization is possible migration of the embolic agent into the venous drainage with an incomplete nidus occlusion, which may lead to severe hemorrhagic complications. This report presents the case of a 29-year-old man who presented with a deep intraparenchymal hematoma on the left side secondary to the spontaneous rupture of a claustral AVM. Upon resorption of the hematoma, the patient underwent an initial therapeutic session of N-butyl-2 cyanoacrylate endovascular embolization, with the purpose of reducing the AVM volume and flow before performing Gamma Knife radiosurgery.

Safety and Clinical Effectiveness of Percutaneous Vertebroplasty in the Elderly (≥80 years).

Purpose: To evaluate the safety and clinical effectiveness of percutaneous vertebroplasty (PVP) in patients aged 80 and over.

Methods: One hundred and seventy-three patients (127 women, 46 men; mean age = 84.2y) underwent 201 PVP procedures (391 vertebrae) in our institution from June 2008 to March 2012.

Has the percutaneous vertebroplasty a role to prevent progression or local recurrence in spinal metastases of breast cancer?

Objective: To evaluate the effectiveness of percutaneous vertebroplasty (PV) on the prevention of progression or local recurrence in patients with spinal metastases from breast cancer.

Materials And Methods: Retrospective study on 55 patients between 27-78 years of age (mean age: 55 years) treated for metastatic breast cancer in the same institution (Curie institute, Paris, France), who underwent percutaneous vertebroplasty (PV) (number of vertebrae treated=137) for spinal metastases from January 2000 to December 2009 at the Pitié-Salpêtrière hospital. Statistical correlation between the local tumor progression/recurrence, and the presence of an epidural or a paravertebral metastatic extension at diagnosis, the rate of cement filling the lesion (<50%, ≥50% but incomplete, complete/almost complete) and radiotherapy was evaluated using Chi(2) and Fisher's exact test.

Occlusion of M1 segment after superficial temporal artery-middle cerebral artery bypass in a giant M1 aneurysm with Onyx-34 injected via a double-lumen balloon under balloon inflation.

A 29-year-old patient attended our institution for recurrent strokes related to a giant partially thrombosed M1 aneurysm. Superficial temporal artery-middle cerebral artery (STA-MCA) bypass and subsequent occlusion of both the aneurysm and the dysplastic M1 segment were planned. However, owing to the shortness of the non-dysplastic segment of M1 and the risk of occlusion of the lenticulostriate arteries, the use of a double-lumen balloon was considered for coiling and subsequent injection of Onyx.

Safety and effectiveness of percutaneous sacroplasty: a single-centre experience in 58 consecutive patients with tumours or osteoporotic insufficient fractures treated under fluoroscopic guidance.

Objective: To report our experience in percutaneous sacroplasty (PSP) for tumours and insufficiency fractures of the sacrum.

Methods: Single-centre retrospective analysis of 58 consecutive patients who underwent 67 PSPs for intractable pain from sacral tumours (84.5 %) or from osteoporotic fractures (15.

Onyx injection by direct puncture for the treatment of hypervascular spinal metastases close to the anterior spinal artery: initial experience.

Presurgical devascularization of hypervascular spinal metastases has been shown to be effective in preventing major blood loss during open surgery. Most often, embolization can be performed using polyvinyl alcohol (PVA) microparticles. However, in some cases, the close relationship between the feeders of the metastases and the feeders of the anterior spinal artery (ASA) poses a risk of spinal cord ischemia when PVA microparticle embolization is performed.

Combined Angio-Seal™ and stenting rescue treatment in a case of iatrogenic common carotid artery dissection during direct puncture for ruptured intracranial aneurysm embolization: a technical note.

Background And Importance: Direct puncture may offer an alternative access for embolization of intracranial aneurysms in patients presenting with tortuous vessels. Nevertheless, major complications such as compressive hematoma and arterial dissection can occur with this technique.

Clinical Presentation: A tight common carotid artery (CCA) dissection was seen secondary to direct puncture in a 72-year-old patient who presented with a ruptured anterior communicating artery (ACom) aneurysm.

Transoral approach for percutaneous vertebroplasty in the treatment of osteolytic tumor lesions of the lateral mass of the atlas: feasibility and initial experience in 2 patients.

Study Design: Case series.

Objective: To report our early experience of percutaneous vertebro-plasty via a transoral approach of the lesions of the lateral mass of C1.

Summary Of Background Data: Percutaneous vertebroplasty has gained acceptance for the treatment of osteolytic lesions of the spine.

Spontaneous closure of intracranial dural arteriovenous fistulas: a report of 3 cases.

Spontaneous closures of dural arteriovenous fistulas (dAVFs) are rare. We present spontaneous occlusion of dAVFs in 3 cases (one type IIa dAVF, one type IIb and one type III). Patients were 3 males with a mean age of 55 years (range 45-61).

Atorvastatin decreases computed tomography and S100-assessed brain ischemia after subarachnoid aneurysmal hemorrhage: a comparative study.

Objective: Statins, which improve the bioavailability of endogenous nitric oxide and upregulate endothelial nitric oxide synthase, have been used to prevent cerebral vasospasm after aneurysmal subarachnoid hemorrhage. The objective of this study was to determine whether statin therapy diminished vasospasm-induced ischemia as assessed using daily measurements of serum S100B, a biomarker for cerebral ischemia, and computed tomography measurement of ischemic lesion volume.

Design: Single-center study of cases and historical controls.

Balloon-assisted embolization of skull base meningioma with liquid embolic agent.

The authors report a novel technique of balloon-assisted embolization of a skull base meningioma supplied by a branch of the cavernous segment of the internal carotid artery using liquid embolic agent. A temporarily inflated balloon distal to the meningioma's feeding vessel may improve the access to this small branch and may reduce the chances of unintended reflux during delivery of the liquid embolic agent.
