Utilisation of the Scepter Mini dual-lumen balloon - An illustrative series.

BACKGROUND: Dual-lumen balloon microcatheters can aid in the safety and efficacy of endovascular embolisation of cerebrospinal vascular malformations. The Scepter Mini dual-lumen balloon is a novel device with a smaller profile than previous balloon microcatheters, opening up new indications not only in the treatment of cerebrospinal malformations but in various other neurovascular therapeutic and diagnostic scenarios. METHODS: Following institutional ethics review board approval, a retrospective review of our prospectively maintained database of cases employing the Scepter Mini dual-lumen microballoon catheter was conducted. Five cases in particular were highlighted, demonstrating utilisation of this device, which may be of interest to the Neurointerventionalist. Patient demographics, procedure details, complications and clinical outcome data were reviewed. RESULTS: Five cases employing the Scepter Mini dual-lumen microballoon catheter are presented; trans-arterial embolisation of cerebral AVM, pre-operative tumour embolisation, diagnostic angiography, trans-venous embolisation of cerebral AVM and trans-arterial embolisation of DAVF. No intraprocedural complications were recorded, one patient had a delayed haemorrhage. CONCLUSION: Potential utilisation of the Scepter Mini lies not only in the trans-arterial embolisation of cerebrospinal vascular malformations, but in a range of other diagnostic and therapeutic indications as demonstrated.

Rare case of basilar artery aneurysm in a young child.

A previously well, 14-month-old girl presented with acute decreased level of consciousness. There was no history of trauma, systemic upset or significant family history. Blood pressure was within normal range and no focal neurological deficit was elicited on examination. Neuroimaging revealed a subarachnoid haemorrhage secondary to a basilar tip aneurysm. Patient underwent endovascular embolisation with good clinical outcome. Follow-up MRI revealed anterior circulation vasospasm, and although clinically asymptomatic, she was treated with a calcium channel antagonist. She was later discharged home with no neurological deficit. Follow-up MRI 3 months following presentation suggested recurrent formation of the aneurysmal sac. The patient then underwent elective endovascular repair 2 months later and was discharged home on antiplatelet therapy with planned close outpatient clinical and radiological surveillance.

Direct puncture of the V3 segment of the vertebral artery in acute basilar artery stroke: an alternative approach in desperate circumstances.

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.
