Female, 71 years old.
Unruptured treatment of Left ICA termination aneurysm.
Incidentally detected (MRA) Left Internal Carotid Artery (ICA)
Previous coiling of acute Anterior Communicating
Artery aneurysm (ACOM) with Sub-Arachnoid Haemorrhage (SAH).
WEB device (MicroVention)
pCONus device (Phenox)
During a multi-disciplinary team meeting, all treatment options
were discussed. It was decided to use the Contour Neurovascular System™.
There are several advantages of the Contour Neurovascular System. Patients potentially avoid the need for a dual antiplatelet therapy regimen, as well as the risks associated with balloon-assisted coiling in Middle Cerebral Artery (MCA) territory.
Additionally, the procedure time is short and can lead to complete obliteration of the aneurysm upon deployment.
Right trans femoral catheterization.
8F sheath placed in right common femoral artery.
6F Neuron MAX (Penumbra, Inc) placed in left internal carotid artery for proximal support.
6F Navien (Medtronic Neurovascular) was used for distal support.
A 3D rotational angiogram was performed. The aneurysm was carefully measured, and diameters taken in both AP and lateral planes.
Sizing of aneurysm
Sizing of the Aneurysm
Anterior Posterior (AP) Diameter: 5.5 mm, Neck: 3.8 mm
Lateral (LAT) Diameter: 5.4 mm
Following careful measurement of the aneurysm, it was decided to utilize a 7 mm Contour device. An XT-27 micro-catheter from Stryker Neurovascular was tracked over a 0.014 Synchro Guidewire, also from Stryker Neurovascular, and carefully navigated into the centre of the aneurysm.
A 7 mm Contour Neurovascular System™ was Implanted.
Immediate stasis was observed within the aneurysm.
No immediate complications were encountered.
Total fluoroscopic time was 16 minutes.
The patient was discharged home in 24 hours with no neurological deficit and mRS 0.
Six-week clinic follow up mRS 0.
The patient was asymptomatic with no neurological deficit.
Imaging and Clinical Follow Up Results
MRA at six-month follow up:
The Left ICA termination appears well occluded on MR and TOF MRA (Raymond Scale 1). The artifact from the device precludes assessment of the aneurysm although there was no signal or flow seen within the aneurysm. Clinical six-month follow up catheter angiogram: Patient was asymptomatic mRS 0 in neurovascular clinic six months following the procedure.
