BACKGROUND AND PURPOSE: Flow diversion is a new strategy for the treatment of complex paraclinoid aneurysms. However, flow diverters have, to date, not been tested in direct comparison with other available treatments. We present a matched-pair comparison of paraclinoid aneurysms treated with the PED versus other endovascular techniques.
Introduction: High-porosity (HP) and flow-diverting (FD) stents are increasingly used to treat intracranial aneurysms. In vivo device deformations and their impact on the porosity of the segment of device lying over the aneurysm neck remain inadequately characterized.
BACKGROUND AND PURPOSE: Restenosis after CAS is a postoperative problem, with a reported frequency of approximately 2%–8%. However differences in stent design, procedure, and the antiplatelet agent appear to affect the incidence of restenosis. We assessed the frequency of restenosis and the effect of the antiplatelet agent CLZ in preventing restenosis after CAS by the standard procedure using the CWS.
Background and Purpose—The role of endovascular therapy for acute M2 trunk occlusions is debatable. Through a subgroup analysis of Prolyse in Acute Cerebral Thromboembolism-II, we compared outcomes of M2 occlusions in treatment and control arms.
Background and Purpose—To assess whether prophylactic postoperative intraaortic balloon counterpulsation (IABC) reduces the risk of poor outcome because of vasospasm following aneurysmal subarachnoid haemorrhage relative to conventional hypervolemic therapy (HT).
Introduction: Intra-arterial mechanical thrombectomy (IAMT) is an endovascular technique that allows for the acute retrieval of intravascular thrombi and is increasingly being used for the treatment of acute ischaemic stroke (AIS). There are currently two anaesthetic options during IAMT: general anaesthesia (GA) and conscious sedation (CS). The decision to use GA versus CS is the source of controversy, as it requires careful balance between patient pain, movement and airway protection whilst minimising time delay and haemodynamic fluctuations. This review examines and summarises the evidence for the use of GA versus CS in the treatment of AIS by IAMT.
BACKGROUND: The association of carotid body paragangliomas with neurovascular structures can cause cranial nerve injury and significant intraoperative blood loss. Preoperative embolization may be performed either percutaneously or transarterially.
BACKGROUND: Arteriovenous malformation (AVM) treatment is multidisciplinary, and the patient may undergo embolization, neurosurgery, or radiosurgery combined. Great improvement in endovascular techniques was provided by the introduction of Onyx with different kinds of approach.
BACKGROUND AND IMPORTANCE: Purely intraorbital arteriovenous fistulas (AVFs), which are rare vascular malformations that clinically mimic carotid-cavernous fistulas (CCFs), involve a fistula from the ophthalmic artery to 1 of the draining ophthalmic veins. We describe a case of an intraorbital AVF treated with transvenous endovascular coil embolization via the inferior petrosal sinus (IPS) route and review the literature on this rare entity.
BACKGROUND: Radiosurgery is the main alternative to microsurgical resection for benign meningiomas.
Long-term Angiographic and Clinical Outcome Following Stenting by Flow Reversal Technique for Chronic Occlusions Older Than 3 Months of the Cervical Carotid or Vertebral Artery
BACKGROUND: Balloon dilatation and deployment of a self-expanding stent is a safe treatment for intracranial atherosclerotic stenoses. The significant recurrence rate might be related to the high radial force of the Wingspan stent.
BACKGROUND: Patients undergoing neurosurgical clipping or endovascular coiling of a ruptured aneurysm may differ in their risk of vasospasm.
BACKGROUND: Stenting for symptomatic intracranial atherosclerotic disease is a therapeutic option in patients in whom medical therapy fails.
BACKGROUND: Despite a high success rate in the stereotactic radiosurgical treatment of intracranial arteriovenous malformations (AVMs) that cannot be safely resected with microsurgery, some patients must be managed after treatment failure.
