Iatrogenic cervical internal carotid artery pseudoaneurysm is a rare and potentially lethal complication following tonsillectomy. It can be complicated by thromboembolism, mass effect and eventually may rupture leading to death. Various endovascular treatment options are available for the management of these pseudoaneurysms, including coil embolization, detachable balloon occlusion, or stent graft placement. Parent artery occlusion using detachable balloons can be a therapeutic option in a subset of patients...

We present a case of supraclinoid internal carotid artery dissection. Eleven months prior, the patient developed isolated periorbital pain and was diagnosed with giant-cell arteritis with iritis. The patient experienced recurrent spells concerning for transient ischaemic attacks and was transferred to our institution for endovascular intervention after head CT revealed an embolic infarct with a 'dense middle cerebral artery sign.' Digital subtraction angiography was negative for occlusion, instead demonstrating luminal stenosis and poststenotic dilatation...

BACKGROUND: The endovascular technique has been recommended over the past few years to extracranial carotid dissection and pseudoaneurysm with promising results, specially after medical therapy failure. Flow-diverting stents are an alternative for complex cases. These stents have proven to be effective treatment devices for intracranial aneurysms. OBJECTIVE: To find out all cases of flow-diverting stents in the treatment of extracranial carotid dissection with or without pseudoaneurysm and compare to our case report...

A nearly 80-year-old man with a history of radiotherapy (RT) and total laryngectomy for laryngeal cancer 25 years previously presented with a rapidly growing mass on the right side of his neck. A huge pseudoaneurysm (pseudoAN) was detected at the right carotid bifurcation, though angiography performed four years previously had shown total occlusion of the internal carotid artery. Stent-assisted coil embolization enabled aneurysm sac shrinkage. Clinicians must be aware that the stump of an arterial occlusion associated with RT can change into a pseudoAN over the long term and must provide follow-up in such cases...

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...

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...

Extracranial internal carotid artery (ICA) pseudoaneurysms are uncommon in the pediatric population and are usually secondary to direct trauma to the vessel. Treatment options include surgery (ligation), anticoagulation therapy and endovascular treatment. Endovascular covered stents have shown good results in adult populations, resulting in occlusion of the aneurysm and preservation of the artery without significant complications. However, there have been only limited reports in the literature reporting endovascular carotid stent placement in the pediatric population...

BACKGROUND: Spontaneous cervical artery dissection (sCAD) is an important etiology of juvenile stroke. The gold standard for the diagnosis of sCAD is convential angiography. However, magnetic resonance imaging (MRI)/MR angiography (MRA) and computed tomography (CT)/CT angiography (CTA) are frequently used alternatives. New developments such as multislice CT/CTA have enabled routine acquisition of thinner sections with rapid imaging times. The goal of this study was to compare the capability of recent developed 128-slice CT/CTA to MRI/MRA to detect radiologic features of sCAD...

OBJECTIVE Flow-diverting devices have been used for the treatment of complex intracranial vascular pathology with success, but the role of these devices in treating iatrogenic intracranial vascular injuries has yet to be clearly defined. Here, the authors report their bi-institutional experience with the use of the Pipeline embolization device (PED) for the treatment of iatrogenic intracranial vascular injuries. METHODS The authors reviewed a retrospective cohort of patients with iatrogenic injuries to the intracranial vasculature that were treated with the PED between 2012 and 2016...

The Pipeline embolization device (PED) is the most widely used flow diverter in endovascular neurosurgery. In 2011, the device received FDA approval for the treatment of large and giant aneurysms in the internal carotid artery extending from the petrous to the superior hypophyseal segments. However, as popularity of the device grew and neurosurgeons gained more experience, its use has extended to several other indications. Some of these off-label uses include previously treated aneurysms, acutely ruptured aneurysms, small aneurysms, distal circulation aneurysms, posterior circulation aneurysms, fusiform aneurysms, dissecting aneurysms, pseudoaneurysms, and even carotid-cavernous fistulas...

We report the case of a patient with ICA mycotic pseudo-aneurysm secondary to Lemierre's syndrome, urgently treated. A 75 years old man presented to E.R. with a left swelling lesion of the neck and complaining left visions lost since that morning, fever, hypotension and dyspnoea. Since fifteen days before developing symptoms, he had sore throat and odynophagia treated with a broad coverage of antibiotic therapy for presumed streptococcal pharyngitis. Preoperative CTA images revealed a circular lesion, involving the common carotid artery, carotid bulb, and the proximal part of the internal and external carotid arteries...

BACKGROUND: The chimney technique has been developed for the treatment of complex aortic aneurysms. We analyzed the midterm to long-term outcomes of this approach from a single- centre experience. METHODS: From October 2008 to July 2016, 58 patients underwent endovascular aortic aneurysm repair using the chimney technique. Indications for treatment were thoracic aortic aneurysm (TAA) (n = 11), thoracoabdominal aortic aneurysm (TAAA) (n = 2), pararenal aortic aneurysm (PAAA) (n= 15), aortoiliac/isolated hypogastric artery aneurysm (n = 25), type I endoleak after previous TEVAR/EVAR (n=4), proximal pseudoaneurysm after AAA open repair (n = 1)...

Segmental arterial mediolysis (SAM) is a non-atherosclerotic, non-hereditary vasculopathy that most commonly involves abdominal aortic branches and predominantly affects middle-age and elderly populations. Lysis of the outer arterial media results in separation of the media from the adventitia leading to dissecting aneurysms and/or pseudoaneurysms. We report a unique case of a 47-year-old man who presented with bilateral internal carotid artery dissection followed by dissections and aneurysms involving multiple visceral arteries...

BACKGROUND: Blunt traumatic aortic injury is the second leading cause of death in trauma patients age 4 to 34. Of the patients that are able to receive treatment, mortality rates as high as 40% have been reported. Endovascular repair options have allowed for more expeditious repairs with reduced iatrogenic trauma; however, when the injury involves the ascending aorta or arch, current endografts lack fenestrations needed for cerebral blood flow. Traditionally, on pump cardiopulmonary bypass with systemic anticoagulation has been used to repair these injuries...

Craniocervical artery dissection is a potentially disabling condition caused by an intimal tear allowing blood to enter and dissect the media in the cranial direction which can occur spontaneously or as a result of trauma. When the dissection extends toward the adventitia, it can form a protrusion from the weakened vessel wall called a pseudoaneurysm, which may become a nidus for distal thromboembolism or cause mass effect on adjacent structures. Accurate and prompt diagnosis is critical as timely treatment can significantly reduce the risk of complications such as stroke...

Introduction Blunt head trauma can injure the cavernous segment of the internal carotid artery (ICA). This may result in a carotid cavernous fistula (CCF). Rarely, a traumatic aneurysm may bleed medially causing massive epistaxis. Case presentation We present two cases of traumatic intracavernous carotid pseudoaneurysms with delayed massive epistaxis. The patients were managed with endovascular treatment involving coil embolization with parent vessel sparing and detachable balloon occlusion with carotid sacrifice...

BACKGROUND: Intracranial pseudoaneurysms are rare vascular defects of arterial walls that are classically the result of traumatic injury, iatrogenic causes, or infection. Idiopathic pseudoaneurysms are seen even less frequently and are often related to atherosclerosis. Pseudoaneurysms are most commonly found along the distal wall of the internal carotid artery, however, can occur at any location in the cerebrovascular circulation. Treatment of these arterial defects is often challenging due to their frail nature...
