BACKGROUND Ruptured aneurysms associated with a partial vertebrobasilar duplication or a persistent primitive hypoglossal artery (PPHA) have been reported. Only rarely has endovascular treatment of ruptured aneurysms in association with both vascular variations been reported. OBSERVATIONS A 66-year-old woman experienced the sudden onset of a severe headache caused by a subarachnoid hemorrhage. Cerebral angiograms demonstrated a prominent PPHA originating from the left internal carotid artery at the C2 vertebral level and a partial vertebrobasilar duplication between the hypoplastic right vertebral artery and proximal basilar artery with a small aneurysm at the proximal end of the duplication from where the anterior spinal artery originated. The left vertebral artery was aplastic. A microcatheter was introduced into the aneurysm via the PPHA under the control of high blood flow, using a balloon-assisted technique. The aneurysm was completely obliterated with a coil. Although small cerebellar and cerebral infarcts developed during the procedure, the patient was discharged without neurological symptoms. LESSONS To avoid serious neurological complications, precise analysis of the complex vascular anatomy, including the anterior spinal artery and hemodynamics, is clinically important for endovascular therapy of cerebral aneurysms in patients with an association between a partial vertebrobasilar duplication and a PPHA.

BACKGROUND An arteriovenous fistula is an abnormal arteriovenous shunt between an artery and a vein, which often leads to venous congestion in the central nervous system. The blood flow near the fistula is different from normal artery flow. A novel method to detect the abnormal shunting flow or pressure near the fistula is needed. OBSERVATIONS A 76-year-old woman presented to the authors’ institute with progressive right upper limb weakness. Right vertebral angiography showed a fistula between the right extracranial vertebral artery (VA) and the right vertebral venous plexus at the C7 level. The patient underwent endovascular treatment for shunt flow reduction. Before the procedure, blood pressures were measured at the proximal VA, distal VA near the fistula, and just at the fistula and drainer using a microcatheter. The blood pressure waveforms were characteristically different in terms of resistance index, half-decay time, and appearance of dicrotic notch. The fistula was embolized with coils and N-butyl cyanoacrylate solution. LESSONS During endovascular treatment, the authors were able to digitally record the vascular pressure waveform from the tip of the microcatheter and succeeded in calculating several parameters that characterize the shunting flow. Furthermore, these parameters could help recognize the abnormal blood flow, allowing a safer endovascular surgery.

We describe the first documented endovascular treatment of vertebral dissecting aneurysm using a Wingspan stent and detachable coils. A 54-year-old man presented with a nonruptured vertebral dissecting aneurysm. Because of the dissecting nature of the vertebral aneurysms, a 3×15-mm Wingspan stent was placed in the left vertebral artery. One month later, several detachable coils were introduced into the aneurysm. Six-month follow-up angiogram confirmed the obliteration. Vertebral dissecting aneurysm can be treated with Wingspan stent placement and detachable coils.

We present a pictorial review of anomalous origin of the left vertebral artery observed in 5 patients imaged in our after-hours trauma radiology unit within a period of 7 days. We raise the question of whether the incidence of anomalous origin of the left vertebral artery quoted in the radiology literature as 5% is really that low, and suggest that the current increased frequency of cross-sectional imaging could elevate the observed incidence of this anomaly in practice. We discuss the implications of vertebral artery anomalies in the endovascular treatment of aortic arch injuries.

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.

BACKGROUND Rheumatoid arthritis (RA) frequently features degeneration and instability of the cervical spine. Rarely, this degeneration manifests as symptoms of bow hunter syndrome (BHS), a dynamic cause of vertebrobasilar insufficiency. OBSERVATIONS The authors reviewed the literature for cases of RA associated with BHS and present a case of a man with erosive RA with intermittent syncopal episodes attributable to BHS as a result of severe extrinsic left atlantooccipital vertebral artery compression from RA-associated cranial settling. A 72-year-old man with RA-associated cervical spine disease who experienced gradual, progressive functional decline was referred to a neurosurgery clinic for evaluation. He also experienced intermittent syncopal events and vertiginous symptoms with position changes and head turning. Vascular imaging demonstrated severe left vertebral artery compression between the posterior arch of C1 and the occiput as a result of RA-associated cranial settling. He underwent left C1 hemilaminectomy and C1–4 posterior cervical fusion with subsequent resolution of his syncope and vertiginous symptoms. LESSONS This is an unusual case of BHS caused by cranial settling as a result of RA. RA-associated cervical spine disease may rarely present as symptoms of vascular insufficiency. Clinicians should consider the possibility, though rare, of cervical spine involvement in patients with RA experiencing symptoms consistent with vertebral basilar insufficiency.

The observation of endovascular treatment of a 34-year-old woman with bilateral dissection lesions of vertebral arteries in V4-segments with occlusion of the right vertebral artery and right posterior inferior cerebellar artery, severe stenosis of the left vertebral artery caused by chiropractic manipulation in the neck region is described. There are intensive staticolocomotor and dynamic coordinating insufficiency, severe neck pain, headache, severe dizziness, Wallenberg syndrome, moderate central tetraparesis. MRI of the brain on the DWI Isotropic identified the hyperintensive round-shaped foci in the right hemisphere of the cerebellum, in the right side of cerebellum worm, in the right side of the medulla oblongata and in the right side of the pons (DWI BSS 3). Selective cerebral angiography was performed an hour after the clinic manifestation. Simultaneously, balloon angioplasty of severe dissection stenosis was performed in the V4-segment of the left vertebral artery by the compliant balloon-catheter Scepter C. In 18 hours from the development of vertebral artery dissection, self-expending stent LVIS was implanted into the left vertebral artery in the zone of dissection lesion. On the control angiograms: the left vertebral artery patency is restored without stenosis all along. The stent is fully opened. A second contrast contour is determined outside the stent in the dissection zone. All the arteries of the vertebrobasilar basin above the vertebrobasilar junction are passable. The V4-segment of the right vertebral artery is contrasted through the vertebrobilar junction. There was a rapid regression of neurological symptoms in the postoperative period. Only mild hypoesthesia on the right side in the outer Sölder’s zone, light coordination disorders on the right were remained. Control selective cerebral angiography revealed recanalization of the right vertebral artery and the right posterior cerebellar artery. But distal basin of the right posterior cerebellar artery is very poorly. The left vertebral artery is passable all over, but in the place of the former dissection, two equivalent arterial «sleeves» were formed according to the fenestration type. One «sleeve» is formed by a stent, the other — outside. All arteries of the vertebrobasilar basin are contrasted. The mild hemihepesthesia on the right side of the face in the outer Sölder’s zone, light coordination disorders on the right are remained. Implantation of the self-expanding stent LVIS allowed to restore the dominant vertebral artery and restrict ischemic brain damage in the brain stem and cerebellum in a patient with a both vertebral arteries dissection lesion caused by chiropractic neck manipulations.

Abstract OBJECTIVE AND IMPORTANCE Recent technological advances have provided clinicians with stents that can be navigated throughout the tortuous proximal vessels of the posterior intracranial circulation. There have been few reports of fusiform and wide-necked aneurysms treated with stents. Of the known risks involved in stent placement in the intracranial circulation, delayed stent thrombosis has not been well described. CLINICAL PRESENTATION A 34-year-old man who experienced the sudden onset of a severe headache with increasing lethargy was found on computed tomographic imaging to have a subarachnoid hemorrhage. Angiography revealed a left vertebral artery fusiform aneurysm that incorporated the posteroinferior cerebellar artery origin. INTERVENTION A low-porosity Magic Wallstent (Boston Scientific, Natick, MA) was placed in the left vertebral artery across the aneurysm and the origin of the posteroinferior cerebellar artery. Angiography performed 9 days later revealed significant reduction in filling of the aneurysm. The patient returned 3 months after stent placement with severe neurological deterioration from a brainstem infarction caused by complete thrombotic occlusion of the left vertebral artery at the stented segment of the vessel. CONCLUSION Stenting of fusiform aneurysms has provided an alternative to surgical clipping or parent vessel reconstruction. With the increasing frequency of intracranial stent placement for various cerebrovascular disease entities, we must become aware of potential complications associated with these procedures. Such awareness may influence decision-making processes regarding treatment and follow-up care.
