Balloon Technique

Abstract Intravascular navigation with nondetachable balloons is a safe, effective method of treatment for inaccessible aneurysms of the internal carotid artery. The rate of ischemic complications is lower than that associated with carotid ligation, and the rate of subsequent hemorrhage is lower than that associated with either carotid ligation or direct clipping. Therefore, for many internal carotid artery aneurysms that originate at or proximal to the ophthalmic artery, the nondetachable balloon technique is an alternative treatment choice. During a 7-year period, 21 aneurysms of the internal carotid artery were treated by the nondetachable balloon technique. All 21 aneurysms were successfully excluded from the circulatory system by either proximal occlusion or trapping of the aneurysm neck. This series consisted of 8 carotid-ophthalmic artery aneurysms, 11 carotid-cavernous aneurysms (6 spontaneous, 5 traumatic), 1 petrous segment aneurysm, and 1 cervical segment aneurysm. At 3 years of follow-up, the following incidences were noted: transient ischemia, 4.7%; infarction, 9.6%; and hemorrhage, 0%. The complications were 1 case of transient hemiparesis and 2 late ischemic events. Fifty per cent of the patients underwent follow-up computed tomography, and thrombosis of the aneurysm was confirmed in all except one case, which was partially thrombosed.

Flow Diverting Stent

The use of flow-diverting stents for intracranial aneurysms has become more prevalent, and flow diverters are now routinely used beyond their initial scope of approval at the proximal internal carotid artery. Although flow diversion for the treatment of cerebral aneurysms is becoming more commonplace, there have been no reports of its use to treat flow-related cerebral aneurysms associated with arteriovenous malformations (AVMs). The authors report the cases of 2 patients whose AVM-associated aneurysms were managed with flow diversion. A 40-year-old woman presented with a history of headaches that led to the identification of an unruptured Spetzler-Martin Grade V, right parietooccipital AVM associated with 3 aneurysms of the ipsilateral internal carotid artery. Initial attempts at balloon-assisted coil embolization of the aneurysms were unsuccessful. The patient underwent placement of a flow-diverting stent across the diseased vessel; a 6-month follow-up angiogram demonstrated complete occlusion of the aneurysms. In the second case, a 57-year-old man presented with new-onset seizures, and an unruptured Spetzler-Martin Grade V, right frontal AVM associated with an irregular, wide-necked anterior communicating artery aneurysm was identified. The patient underwent placement of a flow-diverting stent, and complete occlusion of the aneurysm was observed on a 7-month follow-up angiogram. These 2 cases illustrate the potential for use of flow diversion as a treatment strategy for feeding artery aneurysms associated with AVMs. Because of the need for dual antiplatelet medications after flow diversion in this patient population, however, this strategy should be used judiciously.

Choroidal Artery

✓ A technique combining wrapping and clip occlusion of aneurysms by using polytetrafluoroethylene (PTFE) for treatment of ruptured blisterlike aneurysms of the supraclinoid internal carotid artery (ICA) is described. The diameter of the abnormal arterial lesion along the long axis of the ICA and the distance between the origin of the ophthalmic artery and the origin of the posterior communicating artery (PCoA), or the origin of the PCoA and the origin of the anterior choroidal artery are measured intraoperatively; a strip of PTFE membrane is then trimmed with scissors to match this diameter and distance. After temporarily occluding the cervical ICA, the intracranial ICA that includes the lesion is wrapped with the strip of PTFE, and one or more aneurysm clips are applied parallel to the ICA. This procedure was successfully accomplished in six patients, all of whom had an uneventful postoperative course with no recurrent subarachnoid hemorrhage during the follow-up period. “Wrap-clipping” using PTFE is a useful procedure for management of ruptured blisterlike aneurysms of the ICA.

Carotid Ligation

The two major indications for common or internal carotid ligation are the resection of neoplasm and the control or prevention of hemorrhage. Sixty percent of those undergoing elective carotid ligation and 12% of those undergoing emergency ligation survive these procedures without evidence of neurological sequelae. This uncompromised survival is based upon the presence or rapid developmnt of collateral circulation to the cerebral vascular bed. Arteriographic studies are utilized to illustrate the development of intra- and extracranial collateralization to the internal carotid artery after interruption of the ipsilateral common carotid. The major collateral circuits demonstrated via a case report are as follows: 1) from the vertebral artery to the external carotid and hence to the internal carotid; 2) from the posterior communicating artery to the internal carotid; and 3) from the ophthalmic artery to the internal carotid.

Traumatic pseudoaneurysm is a rare lesion with a high risk of rupture, and represents one of the most difficult lesions to treat, either surgically or endovascularly. Herein, we describe the case of a 32-year-old man with a traumatic pseudoaneurysm of the internal carotid artery, which was treated by overlapped flow diverters (Tubridge). The patient recovered well, and the follow-up angiography at four months showed complete occlusion of the pseudoaneurysm and patency of the internal carotid artery and the ophthalmic artery.

A rare case of a hypoplastic internal carotid artery (ICA) terminating in the ophthalmic artery with multiple intracranial saccular aneurysms in the contralateral ICA, anterior communicating artery fenestration and triple A2 was identified. The aetiology and pathogenesis of ICA hypoplasia are subjected to certain hypotheses. Developing several collaterals to preserve the blood supply of the ipsilateral cerebral hemisphere could result in aneurysm formation due to flow overload on the contralateral vasculature, but it could also result in hemicranial hypoplasia, cerebral atrophy and deep watershed infarcts, as in our case.

ABSTRACTInternal carotid artery (ICA) blister aneurysms are rare and challenging to successfully treat, using contemporary surgical or endovascular approaches, without partial or complete compromise of the parent vessel. We describe the use of a resheathable flow diverter, the Pipeline Flex Embolization Device (PFED) to perform stent-assisted coiling of a ruptured supraclinoid ICA blister aneurysm in a 56-year-old female who presented with a high-grade subarachnoid hemorrhage (SAH). The first PFED was deployed across the aneurysm neck to jail a microcatheter within the aneurysm dome, and then, two small coils were delivered into the aneurysm. After removing the coiling microcatheter, the second PFED was telescoped into the first PFED. There were no postprocedural complications, and follow-up magnetic resonance angiography 15 months after embolization showed complete aneurysm obliteration. Flow-diverting stent-assisted coiling should be considered as a reconstructive, vessel-preserving, endovascular treatment option for appropriately selected patients with ruptured ICA blister aneurysms. However, future studies are necessary to assess the periprocedural safety in the setting of acute SAH.

OBJECTIVEThere are little data in the literature on the characteristics and natural history of unruptured intracranial aneurysms in children. The authors analyzed their experience with unruptured intracranial aneurysms in the pediatric population at their tertiary care pediatric institution over the last 18 years. The first objective was to assess the imaging characteristics and natural history of these aneurysms in order to help guide management strategies in the future. A second objective was to evaluate the frequency of an underlying condition when an incidental intracranial aneurysm was detected in a child.METHODSThe authors conducted a Research Ethics Board–approved retrospective review of incidental intracranial aneurysms in patients younger than 18 years of age who had been treated at their institution in the period from 1998 to 2016. Clinical (age, sex, syndrome) and radiological (aneurysm location, type, size, thrombus, mass effect) data were recorded. Follow-up imaging was assessed for temporal changes.RESULTSSixty intracranial aneurysms occurred in 51 patients (36 males, 15 females) with a mean age of 10.5 ± 0.5 years (range 9 months–17 years). Forty-five patients (88.2%) had a single aneurysm, while 2 and 3 aneurysms were found in 3 patients each (5.8%). Syndromic association was found in 22 patients (43.1%), most frequently sickle cell disease (10/22 [45.5%]). Aneurysms were saccular in 43 cases (71.7%; mean size 5.0 ± 5.7 mm) and fusiform in the remaining 17 (28.3%; mean size 6.5 ± 2.7 mm). Thirty-one aneurysms (51.7%) arose from the internal carotid artery (right/left 1.4), most commonly in the cavernous segment (10/31 [32.3%]). Mean size change over the entire follow-up of 109 patient-years was a decrease of 0.6 ± 4.2 mm (range −30.0 to +4.0 mm, rate −0.12 ± 9.9 mm/yr). Interval growth (2.0 ± 1.0 mm) was seen in 8 aneurysms (13.3%; 4 saccular, 4 fusiform). An interval decrease in size (8.3 ± 10.7 mm) was seen in 6 aneurysms (10%). There was an inverse relationship between aneurysm size and growth rate (r = −0.82, p < 0.00001). One aneurysm was treated endovascularly with internal carotid artery sacrifice.CONCLUSIONSUnruptured pediatric intracranial aneurysms are most frequently single but can occur in multiples in a syndromic setting. None of the cases from the study period showed clinical or imaging signs of rupture. Growth over time, although unusual and slow, can occur in a proportion of these patients, who should be identified for short-term imaging surveillance.

Fusiform dilatation of the internal carotid artery (FDCA) is a known postoperative imaging finding after craniopharyngioma resection. FDCA has also been reported following surgery for other lesions in the suprasellar region in pediatric patients and is thought to be due to trauma to the internal carotid artery (ICA) wall during tumor dissection. Here, the authors report 2 cases of pediatric patients with FDCA. Case 1 is a patient in whom FDCA was visualized on follow-up scans after total resection of a craniopharyngioma; this patient’s subsequent scans and neurological status remained stable throughout a 20-year follow-up period. In case 2, FDCA appeared after resection and fenestration of a giant arachnoid cyst in a 3-year-old child, with 6 years of stable subsequent follow-up, an imaging finding that to the authors’ knowledge has not previously been reported following surgery for arachnoid cyst fenestration. These cases demonstrate that surgery involving dissection adjacent to the carotid artery wall in pediatric patients may lead to the development of FDCA. On very long-term follow-up, this imaging finding rarely changes and virtually all patients remain asymptomatic. Neurointerventional treatment of FDCA in the absence of symptoms or significant late enlargement of the arterial ectasia does not appear to be indicated.
