Abstract BACKGROUND AND IMPORTANCE Partially thrombosed basilar aneurysms have a high morbidity from the rupture risk and mass effect prompting early treatment. Depending on the size and location, they pose a surgical challenge often requiring multiple endovascular treatment modalities. Here we present a partially thrombosed mid-basilar aneurysm successfully coil embolized with direct vertebral artery access and discuss the technical limitations of direct V1 access. CLINICAL PRESENTATION A 70-yr-old woman presented with acute onset headache, nausea, and vomiting. A computed tomography (CT) head demonstrated a hyperdense prepontine mass which was further characterized as a partially thrombosed basilar aneurysm on CT angiography. After multiple failed attempts to access the vertebral artery via femoral and radial access the patient was taken to the operating room (OR) for surgical exposure of the right V1 segment and direct cannulation of the vertebral artery. The aneurysm was successfully coiled and the vertebral artery closed primarily. The patient was discharged home without any neurological deficits. CONCLUSION Partially thrombosed mid-basilar aneurysms are difficult to treat both surgically and endovascularly. We present a case where endovascular access to the aneurysm was very challenging requiring direct exposure and cannulation of the V1 segment to successfully embolize with coils and discuss the technical limitations of this approach.

Distressing Condition

A 76-year-old man was admitted to the hospital with acute onset of involuntary movements of the left side of his body. His neurological examination revealed he was oriented only to himself, and aforementioned movements of his left arm and leg. CT head demonstrated old infarcts in his right aspect of his pons and basal ganglia. Cerebrospinal fluid analysis was unremarkable. He initially had a normal blood glucose with an elevated anion gap and elevated creatine kinase. Brain MRI showed a small lacunar-type ischaemic infarct within the anteromedial aspect of the right cerebral peduncle, which localised to his haemiballism. To prevent worsening rhabdomyolysis associated with his haemiballism, the primary team initiated both tetrabenazine and diazepam. His movements improved after 1 week of medication therapy. This report discusses a thorough workup for this movement disorder and when to intervene for this distressing condition.

During a strangles outbreak within a herd of minature horses, a six week old foal developed acute onset clinical signs of sepsis and neurological deficits. The foal was euthanized and submitted for post-mortem at the Animal Health Laboratories, Guelph Ontario. Gross <em>post-mortem</em> examination noted severe bronchopneumonia, hypopyon of the right eye and a singular cerebellar peduncle abscess. Culture of the lungs and cerebellum produced a pure growth of <em>Streptococcus equi</em> ssp. <em>equi</em>. <em>Streptococcus equi</em> ssp. <em>equi</em>, the causative agent of equine strangles, produces an acute pyrexia, purulent lymphadenopathy of submandibular and retropharyngeal lymph nodes. Commonly, lymph node abscesses rupture and resolve without complication. Rarely, complications may include: dissemination of the bacteria with diffuse abscess formation, immune mediated disease (purpura haemorrhagica), rarely abscess formation within the central nervous system (CNS) can occur. These can be managed medically with appropriate antibiotics and drugs to reduce intra-cranial pressure, however surgical drainage and debulking of the abscess has been attempted successfully in a few cases.

Giant Pseudoaneurysm

Abstract Traumatic pseudoaneurysms of the extracranial vertebral artery rarely occur, because of its deeply protected anatomical location. Because the direct surgical approach has resulted in high morbidity and mortality rates, ligation of the vertebral artery has been adopted, but this can cause an ischemia in the vertebrobasilar system. We report the case of a 73-year-old woman with a huge pseudoaneurysm of the right vertebral artery that occurred after attempted placement of a cardiac pacemaker. The aneurysm was 7 x 7 x 5 cm in size and its neck was situated just distal to the right subclavian artery. Direct surgical repair of the injured vessel and removal of the aneurysm were successfully performed using balloon catheters placed intraoperatively in both the innominate artery and the right vertebral artery.

AbstractA 36-year-old female patient presented to our stroke neurology clinic for progressively worsening intractable, sharp, shooting interscapular pain radiating to the right shoulder and neck, which she had experienced for 4 years. She had previously seen an orthopedist and was referred to a neurosurgeon for surgical intervention after an MRI of the cervical spine showed the C3–C4 right vertebral artery loop protruding into the right C3–C4 neural foramen and compressing the exiting C4 nerve root. MR neurography showed a stable tortuous right vertebral artery loop, causing a mass effect on the dorsal root ganglion. A neuroforaminal decompression surgery was planned. However, the patient visited our stroke neurology clinic for a second opinion before surgery. An MRI of the thoracic spine showed an enhancing soft tissue mass at the right T4–T5 pedicles and adjacent body. A chest CT with contrast showed a 1 cm radiolucent lesion in the superior articular facet of T5, which represented a nidus. A technetium bone scan showed focal increased uptake within the right T5 pedicle, which is indicative of osteoid osteoma. The patient underwent laminectomy/resection and was pain-free at a 6-month follow-up; biopsy confirmed osteoid osteoma. This case illustrates the importance of neurolocalization during diagnostic testing.

Abstract BACKGROUND AND IMPORTANCE: Aneurysms of the posterior circulation may manifest with neurological deficits related to mass effect on the brainstem. We present an unusual case of an aneurysm resulting in selective lower-extremity weakness and gait instability. CLINICAL PRESENTATION: A 61-year-old man presents with progressively worsening gait instability over the course of several months. A magnetic resonance image and computed tomographic angiogram demonstrate a persistent hypoglossal artery associated with an aneurysm invaginating into the pontomedullary junction. The patient manifested only lower-extremity symptoms. An endovascular approach through the right internal carotid artery and persistent primitive hypoglossal artery was assayed, coiling off the aneurysm with complete angiographic occlusion. One month after the procedure, the patient reported marked improvement in symptoms with residual difficulty walking. At the 1-year postprocedure interval, he reported nearly complete resolution of symptoms. CONCLUSION: Endovascular therapy of an aneurysm invaginating into the brainstem is safe and efficacious.

Context: Stroke caused by basilar artery occlusion is rare, corresponding to 1% of strokes. There is no consensus in the literature on the ideal management of this disease at acute phase. However, mechanical thrombectomy may be a viable treatment option. Case report: 68-year-old female, with no comorbidities, admitted to a secondary hospital 14h after headache, dizziness, vomiting and difficulty walking. She was disoriented, with severe dysarthria and dysphonia, horizontal and vertical ophthalmoparesis and pronation of the right upper limb (NIHSS: 4). Cranial tomography was normal and cranial angiotomography showed a basilar artery thrombosis. Patient was out of the window for intravenous thrombolysis and our hospital did not have another possibility of treatment. Due to high morbidity and mortality, also the possibility of neurological deterioration, medical contact was made with a tertiary hospital with hemodynamic service. During patient transference, she evolved with decreased level of consciousness, aphasia and tetraparesis (NIHSS: 18). Upon arrival at the hospital, a thrombectomy was performed due to an important clinical-radiological mismatch, 19 hours within symptoms onset and 3 hours after neurological worsening. After discharge, patient walked with assistance and physical examination showed a significant improvement in neurological deficits (NIHSS: 6). Conclusions: This case demonstrates the importance of engaging Brazil’s public health system in the management of acute ischemic stroke, especially in challenging cases such as basilar artery occlusion. This patient was the first admitted to our hospital to perform a thrombectomy after effective transference for a tertiary hospital and staff engagement of both hospitals.

Abstract Cavernous malformations (CMs) are intracranial vascular anomalies of the brain blood vessels which are usually asymptomatic but sometimes may cause headache, seizures, or focal neurologic symptoms.1 The latter may be attributed to either hemorrhage of the lesion or due to associated mass effect.2 Here, we describe the case of a 27-yr-old woman who had an acute onset of headache and occasional left sided peripheral visual disturbances. A brain computed tomography scan revealed intraparenchymal hemorrhage near the right hypothalamus and a brain magnetic resonance imaging (MRI) was consistent with an anterior perforated substance CM. Medical management was pursued but severe headache persisted for several weeks to the point of interfering with normal daily function. Given the evidence of past hemorrhage and the persistence of symptoms, a microsurgical resection was indicated. She was scheduled for an elective resection through a right frontotemporal craniotomy. The lesion was found in the right anterior perforated substance, just above the optic tract and was resected without complications. The patient was neurologically stable at discharge. At 4-mo follow-up, the patient had a significantly decreased intensity of headache and an adequate resection cavity on MRI. Otherwise, she was neurologically intact. Cavernous malformations of deep brain structures, such as the anterior perforated substance can be surgically treated but carry a challenging procedure with a risk of visual deficits. In the following video illustration, we narrate this operative case and highlight the nuances of this approach. Patient consent was obtained for the submission of the video to this journal.

Objective Extracranial vertebral artery (VA) aneurysms are rare and are often post-traumatic secondary to penetrating or blunt injuries. Primary extracranial VA aneurysms are far less common. Most of these lesions are located in the proximal (V1) and middle (V2) segments of the VA. Method We report an extremely rare case of a giant aneurysm of the extracranial vertebral artery in a 50-year-old woman who presented with a right posterior neck swelling, headache and pain at the site of the mass. Angiography confirmed aneurysm of V3 segment of the right VA. Treatment included ligation of the artery and aneurysmectomy. Result Magnetic resonance angiography at 12 months showed obliterated proximal segment of the right VA with no obvious flow distally. Conclusion Aneurysms of the extracranial VA are clinically relevant because of the associated risks of rupture and distal embolization. For patients with rupture, pending rupture or a significant mass effect due to a giant lesion, surgery is the treatment modality of choice to attain symptomatic relief.

Background and purpose Despite advances in endovascular therapies, some patients experience vertebral artery stenosis or subclavian artery occlusion and may not benefit from less-invasive angioplasty/stenting. This study described 4 cases in which carotid-vertebral transposition (CVT) or carotid-subclavian transposition (CST) was adapted when endovascular treatment was unfeasible or unsuccessful. Presentation Case 1: A 65-year-old woman presented with severe stenosis of the right vertebral artery ostium, dysplastic left vertebral artery, and aneurysmal dilatation of proximal right subclavian artery and brachiocephalic trunk. Case 2: A 23-year-woman had severe stenosis at the first portion of left vertebral artery caused by Takayasu's arteritis. Because endovascular intervention was unfeasible, CVTs were performed in cases 1 and 2. Case 3: A 73-year-old man presented with total occlusion of the proximal right subclavian artery and severe stenosis of the right internal carotid artery. Case 4: A 58-year-old man experienced complete occlusion of the left subclavian artery and severe stenosis of the left common carotid artery. Duplex ultrasonography showed reverse flow in the vertebral artery in keeping with vertebral steal syndrome. Endovascular treatment was unsuccessful because the wire did not cross the occlusion of the subclavian artery. CSTs were performed with concurrent ipsilateral carotid endarterectomy in cases 3 and 4. Conclusion The present case series demonstrated that CST and CVT were effective treatment modalities for subclavian or vertebral artery lesions. Although endovascular stenting and angioplasty have been advocated as first-line management, CST and CVT should be considered as the remedy when endovascular intervention is unsuccessful or unfeasible.

Watershed Infarcts

A 69-year-old man was presented to our emergency department with acute onset of hemianopsia, aphasia and dizziness. He reported that while he was sitting in front of his computer at home, he had performed a bilateral self-massage of his carotid arteries when suddenly the symptoms occurred. A neurological examination revealed a hemianopsia with a visual field loss on the right side. In addition, a mild aphasic syndrome with agraphia and a word-finding disorder (National Institutes of Health Stroke Scale (NIHSS): 3 points) was diagnosed. The initial brain CT scan with CT angiography showed neither an intracerebral haemorrhage nor a cerebral infarction. Also, no occlusion or any signs of artery dissection or a flow relevant stenosis of the brain supplying arteries were found. After excluding other contraindications, an intravenous thrombolysis with weight-adapted alteplase was performed. The symptoms of the patient significantly improved in the short-term follow-up. Three days after admission no neurological deficits remained. The MRI of the brain revealed multifocal, small, left hemispherical strokes in the middle cerebral artery territory. In general, watershed infarcts after carotid sinus self-massage follow a rare ischaemic stroke mechanism. This case emphasises the importance of a detailed anamnestic evaluation to determine the aetiological classification of ischaemic stroke as well as educating patients’ (poststroke) behaviour.
