Abstract BACKGROUND: Large or giant complex vertebrobasilar junction aneurysms have a dismal natural history and are often challenging to treat with standard endovascular or neurosurgical techniques. OBJECTIVE: To report initial experience with endovascular treatment of these aneurysms using flow-diverting stents (FDS). METHODS: Ten patients with FDS treatment of complex vertebrobasilar junction aneurysms were collected from 4 large cerebrovascular centers. Clinical/angiographic presentation and outcome were retrospectively analyzed. RESULTS: Of 10 aneurysms, 7 presented with brainstem compression, 2 with ischemia, and 1 with subarachnoid hemorrhage, and 3 were recurrent after stent-assisted treatments. Eight were giant. Morphology was fusiform in 5, fusiform dissecting in 1, and multilobulated saccular in 4. Six were partially thrombosed. In addition to FDS (mean number of devices, 3.9; range, 1-9), contralateral vertebral artery sacrifice and adjunctive coiling were performed in 9 and 5 of the 10 patients, respectively. At follow-up, 5 of 10 were completely occluded, 4 showed minimal residual filling, and 1 was retreated with an additional FDS. Postinterventionally, worsening mass effect and ischemic complications were seen in 2 and 4 of 10, respectively. Clinical outcome was good in 6 (modified Rankin Scale score, 0-2). Four fatalities were related to sequelae of subarachnoid hemorrhage, late FDS thrombosis, progressive mass effect, and delayed intracranial hemorrhage. CONCLUSION: FDS may be used to treat complex vertebrobasilar junction aneurysms with overall good angiographic outcome. A combined reconstructive/deconstructive approach appears useful to avoid endoleaks. FDS strategies, like other endovascular and neurosurgical approaches to these lesions, are associated with significant risk and therefore should be reserved for those cases in which alternative approaches either are deemed unsafe or are likely to be ineffective.

Abstract BACKGROUND: Optimal management of bilateral vertebral artery dissecting aneurysms (bi-VDAs) causing subarachnoid hemorrhage (SAH) remains unclear. OBJECTIVE: To investigate the treatment methods and outcomes of bi-VDA causing SAH. METHODS: Seven patients were treated endovascularly for bi-VDA causing SAH. Treatment methods and outcomes were evaluated retrospectively. RESULTS: Two patients were treated with 2 overlapping stents for both ruptured and unruptured VDAs, 2 with 2 overlapping stents and coiling for ruptured VDA and with conservative treatment for unruptured VDA, 1 with internal trapping (IT) for ruptured VDA and stent-assisted coiling for unruptured VDA, 1 with IT for ruptured VDA and 2 overlapping stents for unruptured VDA, and 1 with IT for ruptured VDA and a single stent for unruptured VDA. None had rebleeding during follow-up (range, 15-48 months). All patients had favorable outcomes (modified Rankin Scale score, 0-2). On follow-up angiography at 6 to 36 months, 9 treated and 2 untreated VDAs revealed stable or improved state, whereas 3 VDAs in 2 patients showed regrowth. Of the 3 recurring VDAs, 1 was initially treated with IT but recurred owing to retrograde flow to the ipsilateral posterior inferior cerebellar artery (PICA), the second was treated with single stent but enlarged, and the last was treated with 2 overlapping stents and coiling but recurred from the remnant sac harboring the PICA origin. All 3 recurred VDAs were retreated with coiling with or without stent insertion. CONCLUSION: Bilateral VDAs presenting with SAH were safely treated with endovascular methods. However, endovascular treatment may be limited for VDAs with PICA origin involvement.

ABSTRACT Subarachnoid hemorrhage (SAH) with subdural hygroma (SH) was rarely reported after endovascular coiling. A 60-year-old male presented with impaired consciousness and convulsions due to SAH from a ruptured aneurysm. It was managed by endovascular coiling 20 h after the onset of symptoms. Serial brain imaging for 2 weeks revealed progressive bilateral SHs, more on contralateral side of leaking aneurysm. Management of SH was discussed in a multidisciplinary setting to be conservative as there was neither significant mass effect nor hydrocephalus. The patient recovered neurologically except for mild dysarthria. The SH persisted for 2 months and then cleared gradually. We concluded that SH may arise and become symptomatic as an unusual sequela of post-coiling of a ruptured intracranial aneurysm, in which the SH can complicate the clinical course of SAH. However, the symptomatic SH may resolve spontaneously and completely without any intervention, but needs meticulous neurological assessment and follow-up.

We report the clinical and angiographic results of endovascular treatment of unruptured intracranial aneurysms. Over a three-year period, 80 unruptured aneurysms in 74 patients were electively treated with endovascular management. One aneurysm was diagnosed during investigations for a second ruptured aneurysm, 54 aneurysms were incidentally discovered, 18 aneurysms presented with symptoms of mass effect and seven aneurysms presented with symptoms of brain stem ischemia. Mean size of the 80 unruptured aneurysms was 12.5±8.0 mm (range, 2–39 mm). Thirty-six aneurysms (45%) were small (<10 mm), 38 aneurysms (47.5%) were large (10–25 mm), and six aneurysms (7.5%) were giant (25–39 mm). Forty-eight wide-necked aneurysms (60%) were coiled with the aid of a supporting device. The mortality rate was 1.25%, and the overall morbidity was 1.25%. Of these, one of the patients suffered a stroke, leading to severe disability (1.25%). In one patient, the aneurysm ruptured during treatment, resulting in death. Initial aneurysm occlusion was complete (100%) in 76.25% aneurysms, nearly complete (90%–98%) in 10% aneurysms and incomplete (60%–85%) in 13.75% aneurysms. Follow-up angiography was available in 67 patients with 73 treated aneurysms (91.25%) from one to 36 months (mean 9.3 months); partial reopening occurred in 7.5%, mainly large and giant aneurysms (5.5%). Additional coiling was performed in four aneurysms. There were no complications in additional treatments. At 14.1-month clinical follow-up (range, 2 to 36 months), mRS score was 0 in 78.75% patients, 1 in 10% patients, 2 in 8.75% and 3 in 1.25%. There was no aneurysmal rupture during the follow-up period. Endovascular treatment of unruptured intracranial aneurysms has low procedural mortality and morbidity rates.

Abstract OBJECTIVES Endovascular treatment has emerged as a safe procedure for treating chronic DeBakey IIIb dissection. The objective of this study was to investigate the mid-term outcome and temporal pattern of aortic remodelling after endovascular treatment for DeBakey IIIb dissection. METHODS From 2012 to 2017, 85 patients who underwent endovascular aortic repair for DeBakey IIIb dissection were enrolled. The temporal pattern of aortic remodelling in terms of false lumen (FL) thrombosis [level 1 (∼T7), level 2 (T7 ∼ coeliac axis) and level 3 (coeliac trunk ∼ aortic bifurcation)] and aortic diameter [mid-thoracic level (T7), coeliac axis and the largest infrarenal abdominal aorta] was investigated on serial follow-up computed tomography scan. RESULTS Eighty-five patients underwent endovascular treatment during the study period. Male sex was a significant risk factor for repetitive reintervention and segments 2 and 3 FL thrombosis. The preoperative FL diameter at T7 was significantly associated with FL diameter regression. The number of visceral vessels from the FL and residual DeBakey IIIb dissection after type A repair were significant factors for FL growth at the coeliac trunk and at the largest infrarenal abdominal aorta. The overall mortality was 3 (3.6%). CONCLUSIONS Endovascular treatment is a safe strategy in the management of DeBakey IIIb dissection. However, unfavourable aortic remodelling and repetitive reintervention were expected in male patients with a large number of visceral vessels from the FL and residual DeBakey IIIb dissection after type A repair. Endovascular treatment should be cautiously considered, and close follow-up is required for these patients.

ABSTRACT OBJECTIVE Paraophthalmic aneurysms may exert mass effect on the optic apparatus. Although surgical clipping and endovascular coiling of these aneurysms can be complicated by immediate postoperative visual deterioration, endovascular coil embolization has the unique risk of visual complications later (&gt;24 h) in the perioperative period. METHODS Six patients with a delayed onset of vision loss after technically successful coil embolization of paraophthalmic region aneurysms were identified. All available clinical, angiographic, and cross sectional imaging for these patients, in addition to histopathological data, were reviewed. RESULTS Six patients who underwent endovascular treatment of paraclinoid aneurysms at our institutions developed delayed postoperative visual decline. Four were treated with combination hydrogel-coated and bare platinum coils, one with hydrogel-coated coils, and one with bare platinum coils. Three patients presented with some degree of visual impairment caused by their aneurysms. Catheter angiography performed after the visual decline revealed no etiology in any of the cases. Magnetic resonance imaging was performed in all patients and was unremarkable in two. At follow-up, two had improved, three remained unchanged, and one patient died before any follow-up assessment of her vision. CONCLUSION Both acute and delayed visual disturbances can present after the endovascular treatment of carotid artery paraophthalmic aneurysms. Delayed visual deterioration can be observed up to 35 days after embolization. Although the cause is still undefined, it is likely that the more delayed visual deterioration can be attributed to progression of mass effect and/or perianeurysmal inflammatory change. Our case series raises the possibility that this phenomenon may be more likely with HydroCoil (HydroCoil Embolic System; MicroVention, Aliso Viejo, CA). This possibility should be taken into account by neurointerventionists when selecting a coil type to treat large paraophthalmic aneurysms.

Abstract OBJECTIVE: With a globally aging population, it is imperative to develop specific treatment strategies for intracranial aneurysms in the elderly. However, the optimal management of intracranial aneurysms in the elderly remains controversial, particularly for the unruptured aneurysms. Although endovascular treatment is increasingly being used for the management of aneurysms, large endovascular series in the elderly population are relatively lacking, especially with regard to the unruptured aneurysms. We present our single-center endovascular experience in treating intracranial aneurysms in 63 consecutive patients 70 years of age and older. METHODS: Between November 1998 and December 2003, among a total of 990 patients with intracranial aneurysms treated endovascularly at our center, 63 patients (6%) were 70 years of age or older. Forty-one patients presented with subarachnoid hemorrhage (SAH), and 22 presented with symptomatic unruptured aneurysms. A total of 84 aneurysms were detected in these 63 patients. Only those responsible for either the subarachnoid hemorrhage or clinical symptoms (68 aneurysms) were treated. The aneurysm characteristics, endovascular procedures and techniques, angiographic and clinical outcomes, and complications were reviewed. RESULTS: Selective embolization failed in three aneurysms (4%). In the remaining 65 aneurysms, complete occlusion was achieved in 33 aneurysms (51%), neck remnant was observed in 17 aneurysms (27%), and residual aneurysmal filling was observed in six aneurysms (9%). Parent vessel occlusion was used in the treatment of nine aneurysms (13%). Thirteen procedure-related complications occurred (19%), six of which resulted in clinical complications (9%). Nine deaths (14%) occurred; three (5%) were directly related to the endovascular procedures, and six (9%) were related to the medical complications of SAH. The remaining 54 patients had a mean clinical follow-up time of 13 months (range, 1–47 mo). Ninety-one percent (20 out of 22) of the patients with unruptured aneurysms and 89% (25/28) of the patients with low-grade (Hunt and Hess Grade I and II) ruptured aneurysms achieved excellent outcomes (modified Rankin Scale score, 0–1), whereas 77% (10 out of 13) of the patients with high-grade (Hunt and Hess Grade ≥ III) ruptured aneurysms either died or had very poor outcomes (modified Rankin Scale score, 4–5). Angiographic follow-up (mean, 11 mo; range, 3–38 mo) was obtained in 34 of the 54 living patients (63%). Two aneurysms demonstrated minor changes that required no further treatment (5%). Five aneurysms showed major recurrences (17%), all of which were successfully retreated endovascularly. CONCLUSION: The elderly patients should merit strong consideration for endovascular treatment of both ruptured and symptomatic unruptured intracranial aneurysms. However, in elderly patients with high-grade subarachnoid hemorrhage, morbidity and mortality rates remain high.

Our objective was to study the dynamics of remote results of MCA SA endovascular occlusion. 149 patients with MCA SA were examined and operated, 127 patients were selected for 36 months follow-up, 112 patients in 1 year follow-up, 52 patients were to be examined in 23 years, 17 in 45 years and 14 patients in more than 5 years. Endovascular occlusion was carried out by means of different coils during reconstructive 138 (92.6%) and unplanned deconstructive occlusions 8 (5.4%). For planned deconstructions detachable balloons were used 3 (2%). 17 (11.4%) recurrences were diagnosed and 12 (8%) repeated operations were performed. 19 (12.8%) intra-and postoperative complications/ predictors and 18 (12.1%) complications unrelated to surgery were observed in the first 30 days and only 1 (1.1%) mass effect was identified in 36 months. After our research we were ableto trackthe dynamicsof thepatientslife quality according totheRankinscale; tomonitorthe changes in SA occlusion degree; to define the frequency of recurrences and complications/predictors of complications and to determine the amount of reoperations. We noted a considerable increase in the quantity of total occlusions after reoperations, which resulted in much better filling of the CA cavity, because the prophylaxis of the repeated hemorrhages is the main goal of SA endovascular treatment.

Abstract OBJECTIVE: To report long-term imaging follow-up and clinical outcome of 13 patients with a giant vertebrobasilar aneurysm treated by parent artery occlusion (PAO). METHODS: From 1994 to 2000, 13 consecutive patients with a giant vertebrobasilar aneurysm were treated by PAO. Symptoms were related to mass effect in nine patients and to a subarachnoid hemorrhage in four. Endovascular treatment consisted of aneurysm trapping in nine patients and occlusion of one or both vertebral arteries in four. We assessed the clinical outcome and imaging findings in all patients during a 28-month period. RESULTS: Endovascular treatment resulted in clinical improvements in eight patients, worsening of symptoms in four, and death in one. One woman with a ruptured vertebral aneurysm died from a rebleeding after PAO without trapping. One man developed a brainstem infarction after lower basilar artery occlusion and incurred hemiparesis. In three patients, symptoms of mass effect increased after the procedure. Long-term follow-up revealed good or excellent clinical outcome in all patients and a sharp decrease in size of the thrombosed aneurysm in nine patients. One basilar aneurysm recanalized despite selective coiling and subsequent bilateral vertebral artery occlusion; one vertebral aneurysm and one basilar aneurysm did not decrease in size despite complete occlusion. CONCLUSION: Giant vertebrobasilar aneurysms are rare and challenging lesions for both neurosurgeons and neurointerventionalists. Their treatment by endovascular PAO remains safe and effective. Early clinical worsening may be observed, but long-term follow-up shows good or excellent results in most patients. This treatment can be carried out with minimal morbidity and mortality using clinical and angiographic monitoring.

Object A series of 306 consecutive patients with an anterior communicating artery (ACoA) aneurysm is presented. The goal in this study was to report the results of endovascular treatment of ACoA aneurysms in these patients. Methods The aneurysms were managed with an endovascular approach in which detachable coils were used. A brief anatomical description of the ACoA and its branches as well as a review of the surgical and endovascular literature is presented. The “ACoA Syndrome” (that is, amnesia and personality changes), which may occur after subarachnoid hemorrhage, is briefly reviewed and described. Recent technical developments that can lead to improved results are also discussed. Results Of the 306 aneurysms, 268 (87.5%) were small, 30 (10%) were large, and 8 (2.6%) were giant. One hundred ninety-three aneurysms (63%) had a small neck, whereas 113 (37%) had a wide neck. Sixty-five lesions (21%) were incidental, 5 (2%) presented with symptoms of mass effect, and 236 (77%) presented with a subarachnoid hemorrhage. A complete aneurysm occlusion was attained in 139 cases (45.5%), a neck remnant was detected in 145 (47.5%), and in 22 cases (7%) a residual filling of the aneurysm was observed. Regarding the clinical neurological outcome, 280 patients (91.5%) remained neurologically intact, improved, or unchanged from their initial clinical status. Two large, wide-necked, subtotally occluded aneurysms ruptured 3–7 months after the procedure, with subsequent death of the patients. The procedure-related morbidity and mortality rates were 3.5% (11 cases) and 1% (3 cases), respectively. Conclusions The inherently lower risk of injuring or occluding the delicate branches and perforating vessels arising from the ACoA makes the endovascular approach attractive, interesting, and elegant.
