“…[1][2][3][4] The presence of multiple perforators in this area along with the angle of origin (often skewed toward the MCA or the anterior cerebral artery primarily) can make treatment challenging. 3 Additionally, the increased hemodynamic stress at this level translates into a higher rate of recurrence compared with aneurysms in other locations. 4,5 Several studies have focused on the surgical management of ICA bifurcation aneurysms.…”

BACKGROUND AND PURPOSE: Endovascular coiling of internal carotid artery bifurcation aneurysms can be challenging due to unfavorable morphologic features. With improvements in endovascular techniques, several series have detailed the results and complications of endovascular treatment of aneurysms at this location. We performed a systematic review and meta-analysis of published series on the endovascular treatment of ICA bifurcation aneurysms, including a tertiary referral center experience.

“…Internal carotid artery (ICA) bifurcation aneurysms are uncommon, only accounting for about 2%-9% of intracranial aneurysms (11,16,19,22). Clipping is challenging for neurosurgeons due to their deep location, and vital perforators surrounding or adherent to the aneurysms (8,11,16).…”

“…Clipping is challenging for neurosurgeons due to their deep location, and vital perforators surrounding or adherent to the aneurysms (8,11,16). In one larger series, only 68.6% (48/70) of the reported patients had favorable outcome (good recovery or moderate disability) (8).…”

AIm: Stent placements for the treatment of complex internal carotid bifurcation aneurysms are not well documented yet. In this article, we reported a series of 16 such cases to evaluate the feasibility, safety and effectiveness of stent placement for these particular lesions. results: Sixteen stents, including 10 Enterprise, 4 Neuroform, 1 Solitaire and 1 one balloon-mounted coronary stent (BX), were successfully deployed in this series. Immediate angiogram showed complete occlusion in 5, neck remnant in 2 and residual sac in 9. No procedure-related complication occurred. Angiographic follow-up results (mean, 12.1months) were available in 15 patients, 9 of the aneurysms were cured, 1 was improved, 3 were stable, 2 were recanalized, and 1 was retreated. Clinical follow-up (mean, 28.6months) of all 16 patients demonstrated no neurologic deterioration or rebleeding.COnClusIOn: Our result suggests that stent placement for the treatment of complex ICA bifurcation aneurysms is feasible and safe. However, its efficacy should be further evaluated by larger case series and more adequate follow-up. BulGulAr: 10 Enterprise, 4 Neuroform, 1 Solitaire ve 1 balona monte edilmiş koroner stent (BX) dahil olmak üzere 16 stent bu seride başarıyla yerine yerleştirildi. Hemen yapılan anjiyogram 5'inde tam oklüzyon, 2'sinde kalan boyun kısmı ve 9'unda rezidüel kese gösterdi. İşlemle ilgili komplikasyon oluşmadı. Anjiyografik takip sonuçları (ortalama 12,1 ay) 15 hastada mevcuttu ve anevrizmaların 9'u tamamen iyileşmişti, 1'i daha iyiydi, 3'ü stabildi, 2'sinde tekrar kanalizasyon vardı ve 1'i tekrar tedavi edildi. Klinik takip (ortalama 28,6 ay) 16 hastanın hiçbirinde nörolojik bozulma veya tekrar kanama göstermedi. sOnuÇ: Sonucumuz kompleks IKA bifurkasyon anevrizmaları için stent yerleştirmenin kullanılabilir ve güvenli olduğunu düşündürmektedir. Ancak etkinliği daha büyük vaka serilerinde ve yeterli takiple daha ileri olarak değerlendirilmelidir.

Different ophthalmic artery origins: Embryology and clinical significance

This retrospective study gives a summary of ophthalmic artery (OA) variations to serve as guidelines for surgical interventionists and trainees. Pubmed and Medline searches were conducted. The OA usually arises intradurally (superomedial, anteromedial, or rarely superolateral) from the internal carotid artery (ICA). Rare extradural origin (primitive dorsal OA) (PDOA) remnant and extremely rare interdural origin (primitive ventral OA) (PVOA) remnant are of significance when sectioning the dural ring. Rarely, a persistent PDOA with ICA origin, or a PDOA remnant with inferolateral trunk origin, enters the orbit via the superior orbital fissure (SOF) for sole or partial orbital supply. Extremely rare, the PDOA and PVOA persist and form double OAs that arise from the ICA and run via the SOF and optic foramen. Occasionally, the OA arises from the middle meningeal artery (MMA), when both the PDOA and VDOA regress and enter the orbit via the SOF. Sole orbital supply via the external carotid artery (ECA), i.e. meningo-ophthalmic artery and/or MMA branches, or dual OAs (ECA and ICA origins) may occur. Other rare OA origins include anterior or posterior communicating artery; anterior or middle cerebral artery; basilar artery; posterior inferior cerebellar artery; and the carotid bifurcation. Primitive arteries (persistent or remnant), and/or abnormal anastomoses play pivotal roles in manifestations of OA variations. Of clinical importance are orbital collateral routes and dangerous extracranial-intracranial anastomoses. Awareness of OA origins and collateral routes is imperative for transarterial embolizations or infusion chemotherapy in the ECA territory to prevent visual complications.
