We report the successful treatment of multiple ruptured fusiform middle cerebral artery (MCA) aneurysms in a 10-month-old girl. This previously healthy infant presented with subarachnoid haemorrhage and was found to have multiple irregular dilatations of the superior division branch of the right MCA. Cerebral angiography was performed and confirmed the presence of multiple fusiform aneurysms of the MCA. After multidisciplinary team discussion, it was decided to treat the aneurysms with endovascular approach, using a flow-diverter. Microsurgical clipping was deemed risky because of the high likelihood of parent artery occlusion and expectant management was also considered inappropriate because of the risk of re-bleeding. Dual antiplatelet therapy was started, and a flow-diverter was successfully delivered in the superior division branch of the right MCA. The post-operative course was uneventful, MRI at 12 months did not show any sign of recurrence and at 3 years of age the patient had a normal neurological examination.

AbstractBlister aneurysms pose significant diagnostic and therapeutic challenge to neurointerventionists as well as neurosurgeons. Fragile nature of these aneurysms with involvement of the adjacent parent artery makes surgical options more difficult and complicated. Various endovascular treatment options such as overlapping stent, parent artery occlusion, and flow diverter placement are available in the present era. Though side wall aneurysms can be managed with flow diverter placement, bifurcation aneurysms are difficult to treat with these devices due to possibility of compromised flow in covered branch arteries. Blister aneurysms of the middle cerebral artery (MCA) are rare, and their treatment can be challenging when they are treated by endovascular methods with either overlapping stent or flow diverter placement. The authors report a case of ruptured MCA trifurcation blister aneurysm treated with shelfing technique using braided stent monotherapy along with coil embolization. The patient had good clinical outcome (modified Rankin’s scale 1 [mRS-1]) at discharge and complete aneurysm occlusion on follow-up angiogram after 6 months.

One Year

A fusiform aneurysm in the terminal M1 middle cerebral artery (MCA) segment was treated by a construction of a high-flow arterial extracranial-intracranial (EC-IC) bypass. Due to severe bypass vasospasms, local vasodilating agents together with percutaneous angioplasty and stent implantation were applied, but failed due to subsequent bypass occlusion. To remedy this complication a new bypass was created from a segment of the saphenous vein, followed by MCA aneurysm embolization and parent artery occlusion. One year after the surgery, the venous bypass remains patent and the aneurysm occluded, with the patient fully active, without any neurological sequelae.

Dissecting Aneurysms

Peripheral cerebral aneurysms are difficult to treat with preservation of the parent arteries. We report the clinical and angiographic outcome of 12 patients with cerebral aneurysms located peripherally. In the past five years, 12 patients, six females and six males, presented at our institution with intracranial aneurysms distal to the circle of Willis and were treated endovascularly. The age of our patients ranged from four to 58 years with a mean age of 37 years. Seven of the 12 patients had subarachnoid and/or intracerebral hemorrhage upon presentation. Two patients with P2 dissecting aneurysms presented with mild hemiparesis and hypoesthesia, one patient with a large dissecting aneurysm complained of headaches and two patients with M3 dissecting aneurysms had mild hemiparesis and hypoesthesia of the right arm. Locations of the aneurysms were as follows: posterior cerebral artery in seven patients, anterior inferior cerebellar artery in two, posterior inferior cerebellar artery in one, middle cerebral artery in two. Twelve patients with peripheral cerebral aneurysms underwent parent artery occlusion (PAO). PAO was performed with detachable coils. No patient developed neurologic deficits. Distally located cerebral aneurysms can be treated with parent artery occlusion when selective embolization of the aneurysmal sac with detachable platinum coils or surgical clipping cannot be achieved.

Flow Diverters

Aim Flow diverters are increasingly used to treat aneurysms, but treatment is not always effective. The management of aneurysms that fail to occlude following flow diversion is problematic. We aimed to reproduce failures in an animal model and study re-treatment with additional flow diverters alone or with flow diverters and liquid embolic agent. Material and methods Twenty wide-necked aneurysms were created at the carotid-lingual bifurcation in 10 dogs, and were treated with flow diverters 4–6 weeks later. Follow-up angiography was performed at three months. Suitable residual aneurysms were randomly allocated: re-treatment with flow diverters alone ( n = 6), or with the injection of liquid embolic between two layers of flow diverters ( n = 4) or no re-treatment ( n = 2). Angiography was repeated three months later, followed by euthanasia, photography and pathology. Results Patent wide-necked aneurysms were produced in 17/20 attempts (85%); three months after flow diversion there were 15/17 (88%) residual aneurysms. In three cases, re-treatment was not possible because the flow diverter had prolapsed into the aneurysm, leaving 12 aneurysms to study. Re-treated aneurysms showed improved angiographic results at six months (median score of 2; P = 0.03), but residual aneurysms were present in all cases. Parent artery occlusion occurred in two aneurysms treated with flow diverter plus liquid embolic. At pathology, aneurysms were only partially filled with thrombus; leaks through the flow diverters were found in the neointima connecting the arterial lumen to residual aneurysms. Conclusion Re-treatment of residual flow-diverted experimental aneurysms with additional flow diverters did not lead to aneurysm occlusion.

The Right

We treated a 70-year-old man with a giant paraophthalmic region aneurysm of the right internal carotid artery using the parent artery occlusion technique with three detachable balloons. Initially, the patient did well, but migration of the distal balloon into the aneurysm was detected seven months later. This report suggests that initial parent artery occlusion using balloons will not always induce permanent thrombosis of a large aneurysm, because the occlusion and thrombosis is strictly dependant on the position of the balloons that are used, and adjunct use of coils may be indicated.
