Traumatic carotid cavernous fistula (CCF) presents most commonly as a direct connection between the cavernous segment of internal carotid artery (ICA) and cavernous sinus (CS), and often accompanies basal skull fracture (BSF). The most frequently reported signs and symptoms are proptosis, chemosis, and bruit. Epistaxis is uncommon symptom of CCF. A 63-year-old man with a history of BSF due to blunt head trauma eight months previously was referred to our emergency room for massive epistaxis. Cerebral angiography demonstrated a high-flow CCF with a connection between the supraclinoid portion of left ICA and CS via a pseudoaneurysm, suggesting the life-threatening epistaxis had been caused by high-flow shunting, through the gap created by the BSF...

Erdheim-Chester disease (ECD) is a rare non-Langerhans cell histiocytosis. It is characterized by multiple xanthogranulomatous masses throughout the body, predominantly in the tibia. One of the characteristic radiological findings of the lesions associated with ECD is a "coated artery," which is often observed in the aorta. Although approximately one-fourth of ECD cases involve the central nervous system (CNS), an intracranial-coated artery has only been reported in four cases. We report a case of ECD that involves the CNS and has the unique appearance of a coated vertebral artery (VA)...

Pituitary Apoplexy (PA) is defined as a clinical syndrome comprising headache, visual deficits and altered sensorium, which can result from haemorrhage or infarction of the pituitary gland. Acute ischaemic stroke following PA is very rare. We are presenting a 35-year-old young otherwise healthy lady who presented with neuro ophthalmological and vascular symptoms on a background of PA. Imaging revealed a pituitary macro adenoma with parasellar extension with internal bleed. Cerebral angiography revealed that the mass compressed the bilateral cavernous sinuses (left more than right), resulting in obliteration of the cavernous portion of the left Internal Carotid Artery (ICA)...

BACKGROUND: Ophthalmoplegia secondary to a traumatic dissecting aneurysm in the cavernous segment of internal carotid artery (ICA) is a relatively rare entity. Anticoagulant or antiplatelet therapy is the preferred treatment option for carotid dissections. However, endovascular interventions are noninvasive and alternative methods to surgery, especially in cases of aneurysms that do not respond to medical therapy. CASE REPORT: We report of a 19-year-old man presenting with left-sided, total ophthalmoplegia after a traffic accident...

BACKGROUND: Direct carotid-cavernous sinus fistulas (CCF) are high flow arteriovenous shunts that are typically the result of a severe head injury. The endovascular treatment of these lesions includes the use of detachable balloons, coils, liquid embolic agents, and covered stents. To minimize the chance of treatment failure and subsequent complications, endoluminal reconstruction using a flow-diverting stent may be added to the treatment construct . METHODS: We present 3 cases and review the existing literature...

Bilateral traumatic carotid-cavernous fistula(CCF)is rare. It is most commonly caused by a direct head or face injury involving the cavernous sinus and develops immediately after trauma. We report a case of bilateral traumatic CCF that occurred as an intracerebral hematoma(ICH)mimicking apoplexy 5 months later. We treated the patient with point occlusion of venous reflux causing an ICH using coil embolization to remove the hematoma. Three days after we performed trans-venous occlusion of the intercavernous connection and right cavernous sinus using coil embolization through the right inferior petrosal vein, it was identified that the left CCF was occluded after first embolization into the left sylvian vein...

The authors demonstrate the use of an endovascular plug in securing a carotid artery pseudoaneurysm in an emergent setting requiring craniotomy for a concurrent subdural empyema. They describe the case of a 14-year-old boy with sinusitis and bifrontal subdural empyema who underwent transsphenoidal exploration at an outside hospital. An injury to the right cavernous segment of the ICA caused torrential epistaxis. Bleeding was successfully controlled by inflating a Foley balloon catheter within the sphenoid sinus, and the patient was transferred to the authors' institution...

This is a case of a high-flow, post-traumatic direct carotid-cavernous fistula with a widened arterial defect and a large-diameter internal carotid artery (ICA). The unique aspect of this case is the oversized ICA, >8mm in diameter, which is both a pathological and a therapeutic challenge, given the lack of available neuroendovascular devices for full vessel reconstruction. We present a planned two-stage embolisation paradigm for definitive treatment. Transarterial coil embolisation is performed as the first stage to disconnect the fistula and normalise flow in the ICA...

BACKGROUND: Coaxial catheter support systems provide a safe and stable foundation in endovascular treatment of intracranial aneurysms. Increasingly, robust distal intracranial support is sought during complex neurointerventions. The AXS Catalyst 5 distal access catheter (Cat5) is a new intracranial catheter designed for improved trackability and stability. We report the first experience using Cat5 for aneurysm treatment by flow diversion. METHODS: A single-center aneurysm database was reviewed for cases of aneurysm treatment with the Pipeline embolization device (PED) that utilized Cat5...

Background Double lumen balloon catheters (DLBCs) are currently used in the treatment of intracranial aneurysms, especially when involving balloon or stent-assisted coiling. The existing DLBCs allow the delivery of self-expandable stents but do not offer the possibility to deploy flow-diverters. Despite the increasing use and success of flow-diverters, there have been numerous reports of procedural complications such as early in-stent thrombosis or delayed distal embolization. It seems that these complications can be avoided by correct stent positioning and adequate wall apposition, achieved either by manoeuvres with the microguidewire and/or microcatheter or by performing balloon angioplasty following an exchange guidewire manoeuvre...
