Abstract OBJECTIVE To report a case of successful recanalization using the combination technique of reverse flow and downstream filtering in chronic total occlusion of the bilateral vertebral artery (VA). Clinical Presentation A 59-year-old man had experienced attacks consisting of vertigo and/or dysarthria more than 1 year before presentation. He experienced symptoms despite the administration of antiplatelet drugs and presented to our institution. Diagnostic cerebral angiography demonstrated that the right VA was not occluded at the ostium but, rather, along its midcervical portion and that the left VA ended in the left posterior inferior cerebellar artery. Intervention Long chronic total occlusion of the right cervical VA was recanalized successfully and safely by reverse flow and downstream filtering with proximal flow blockade and a distal filter device positioned in the right brachial artery. Follow-up angiography at 1 year demonstrated no re-occlusion. The patient's symptoms disappeared after recanalization and did not recur. To our knowledge, there are no reports describing successful angioplasty and/or stenting for long chronic total occlusion of the cervical VA. CONCLUSION Stenting using the combination technique of reverse flow and downstream filtering can safely open even long chronic cervical VA occlusion and may be effective in the treatment of patients experiencing vertebrobasilar insufficiency due to bilateral chronic VA occlusion.

Abstract BACKGROUND AND IMPORTANCE: This article describes delayed endovascular revascularization in a patient with clinical and radiographic evidence of posterior circulation hemodynamic failure in the setting of intracranial occlusive lesions. CLINICAL PRESENTATION: A 48-year-old man presented with a 6-week history of progressive headache, nausea, and ataxia. Bilateral intracranial vertebral artery occlusions and a left posterior inferior cerebellar artery stroke were diagnosed, and the patient began warfarin therapy. Despite these measures, the patient developed dense lower cranial neuropathies, including severe dysarthria, decreased left-sided hearing acuity, and left facial droop. He presented at this point for endovascular evaluation. The patient underwent successful revascularization with intravascular Wingspan stents (Boston Scientific, Natick, Massachusetts) in a delayed fashion (approximately 6 weeks after his initial stroke presentation). His neurological syndrome stabilized and began to improve slowly. CONCLUSION: Patients with arterial occlusion should be evaluated acutely for potential revascularization. In the posterior circulation, clinical progression may supplant physiological imaging in the assessment of hemodynamic collapse. A subpopulation of patients will present with progressive deficits distinct from extracranial manifestations of vertebrobasilar insufficiency; these patients should be considered for delayed revascularization.

Abstract Intracranial vertebral endarterectomy was performed on six patients with vertebrobasilar insufficiency in whom medical therapy failed. The patients underwent operations for stenotic plaque in the intracranial vertebral artery with the opposite vertebral artery being occluded, hypoplastic, or severely stenosed. In four of the patients, the stenosis was mainly proximal to the posterior inferior cerebellar artery (PICA). In this group, after endarterectomy, the vertebral artery was patent in two patients, and their symptoms resolved: in one patient the endarterectomy occluded, but the patient's symptoms improved; and in one patient the endarterectomy was unsuccessful, and he continued to have symptoms. In one patient, the plaque was at the origin of the PICA. The operation appeared technically to be successful, but the patient developed a cerebellar infarction and died. In one patient the stenosis was distal to the PICA. During endarterectomy, the plaque was found to invade the posterior wall of the vertebral artery. The vertebral artery was ligated, and the patient developed a Wallenburg syndrome. The results of superficial temporal artery to superior cerebellar artery anastomosis are better than those for intracranial vertebral endarterectomy for patients with symptomatic intracranial vertebral artery stenosis. The use of intracranial vertebral endarterectomy should be limited to patients who have disabling symptoms despite medical therapy, a focal lesion proximal to the PICA, and a patent posterior circulation collateral or bypass.

Purpose: CTA is becoming the frontline modality to reveal aneurysms in patients with SAH. However, in about 20% of SAH patients no aneurysm is found. In these cases, intra-arterial DSA is still performed. Our aim was to evaluate whether negative findings on CTA can reliably exclude aneurysms in patients with acute SAH. Materials and Method: We conducted a retrospective analysis of all DSA performed from August 2010 to July 2014 in patients with various indications. We selected patient who presented with SAH and had a negative CTA. Findings of the CTA were compared with DSA. Results: 857 DSA were performed during the study period. 51(5.95%) patients with SAH and negative findings on CTA who underwent subsequent DSA were identified. Of these, only 3(5.9%) of patients had positive findings on the DSA. One patient had a posterior inferior cerebellar artery aneurysm on the DSA, not seen on CTA due to the incomplete coverage of the head. Second patient’ CTA did not show any evidence of aneurysm. DSA showed suspicious dissection of the right vertebral artery, potentially iatrogenic. The third patient’s DSA showed suspicious tiny protuberance from left ICA, possibly infundibulum. Conclusion: In patients with SAH, negative CTA findings are reliable in ruling out aneurysms in any pattern of SAH on CT.

Traumatic vessel perforation is a potential complication of chronic total occlusion (CTO) percutaneous coronary artery intervention (PCI). A rare consequence of this complication is a coronary-cameral fistula. The management of this condition is not well elucidated. Herein, we present such a case of symptomatic left anterior descending to the right ventricle (LAD-RV) fistula which was treated with coil embolization.

Vertebral artery disease (VAD) is a significant cause of severe symptoms or stroke. Approximately 25 to 30% of strokes involve the posterior circulation system; VAD will be present in 20% of these and will be the source in about 10%. The ability to properly diagnose, manage, and treat VAD is an important skill for practitioners caring for patients with extracranial cerebral occlusive disease. This review covers anatomy, presentations of VAD, evaluation, patterns of disease, treatment, and other vertebral artery (VA) syndromes. Tables outline symptoms and differential diagnoses of vertebrobasilar insufficiency, etiologies of VA compression syndromes, posterior circulation cerebrovascular accident symptoms and associated syndromes, and ultrasonography velocity and VA stenosis. Figures show the anatomy of the VA, circle of Willis, aberrant arteries, VA compression, ischemic posterior circulation, collateral pathways to the VA, common disease patterns in VAD, VA to carotid artery anastomosis, incision for the V3 bypass, VA aneurysm, VA dissection, angiography of the right VA, giant cell arteritis, and fibromuscular dysplasia. Radiologic videos are provided. This review contains 15 figures, 6 tables, 7 videos, and 71 references.

A patient in his mid-40s presented with acute basilar artery thrombosis 7 hours postsymptom onset. Initial attempts to perform mechanical thrombectomy (MT) via the femoral and radial arterial approaches were unsuccessful as the left vertebral artery (VA) was occluded at its origin and the right VA terminated in the posterior inferior cerebellar artery territory, without contribution to the basilar system. MT was thus performed following ultrasound-guided direct arterial puncture of the left VA in its V3 segment, with antegrade advancement of a 4 French radial access sheath. First pass thrombolyisis in cerebral infarction (TICI) 3 recanalisation achieved with a 6 mm Solitaire stent retriever and concurrent aspiration on the 4 French sheath. Vertebral closure achieved with manual compression.

Pica Aneurysms

Vertebral artery (VA)-posterior inferior cerebellar artery (PICA) aneurysms are rare lesions that are difficult to treat with both endovascular and surgical techniques. Tight angulation of the PICA from VA may make access to the PICA difficult from ipsilateral VA if adjunctive techniques are needed. Recently, the safety and efficacy of retrograde access have been reported. We report a case of endovascular treatment for a VA-PICA aneurysm with a stent-assisted technique using retrograde access via contralateral persistent primitive proatlantal artery (PPA). The patient was a 76-year-old woman with an unruptured VA-PICA aneurysm on the dominant VA side. Coil embolization with a stent-assisted technique using retrograde access seemed appropriate. However, the origin of the left VA was not confirmed. Left common carotid artery angiography demonstrated that the PPA (type 1) branching from external carotid artery joined the VA V4 segment. Retrograde access via the PPA for stenting was performed. A microcatheter for stenting was retrogradely advanced to the right PICA at ease. After deploying the stent, coil insertion was completed from the right VA, and the final angiogram showed adequate occlusion of the aneurysm with preservation of the PICA. Thus, PPA may be an approach route in the treatment of VA-PICA aneurysms with unconfirmed contralateral VA orifice and apparent PPA on angiography, when retrograde access is needed.

We present the case of a balloon-assisted, stent-supported coil embolization of a basilar tip aneurysm. Initially, a balloon extending from the basilar artery into the right PCA was placed.3 However, even with a more proximal purchase, coils were found to impinge on the left PCA. Subsequently, a transcirculation approach was performed, where the left posterior communicating artery was utilized as a conduit for balloon support and the coils were embolized from the ipsilateral vertebral artery.1 However, after this transcirculation approach was completed, there was a coil tail extruding from the aneurysm. The balloon was then removed over an exchange wire and a horizontal stent advanced, spanning the entire neck of the aneurysm, eliminating the extruded coil.2The video can be found here: http://youtu.be/bMbtZoPnYvo.
