Vertebral Artery-to-Vertebral Artery Bypass with Interposed Radial Artery or Occipital Artery Grafts: Surgical Technique and Report of Three Cases

Radical treatment for bilateral vertebral artery dissecting aneurysms by reconstruction of the vertebral artery

“…Finally, if one side of the bilateral VADAs is treated by VA reconstruction, the treatment of the contralateral VADA is only parent artery occlusion, which is known to provide reliable outcomes. 10,12,22,34 Vascular reconstruction of the VA, 20,21 such as V 3 -RAG-V 4 anastomosis as the initial operation, is the most useful microsurgical method of treating bilateral VADAs. Favor-able outcomes can be achieved if performed by a skilled neurosurgeon.…”

“…Concurrently, there has been a decline in open surgery for VADAs because of the difficulty of treating these aneurysms. However, recent technical and instrumental improvements for vascular reconstruction, 17,20,21,41 as well as advances in skull base techniques, 14,15,26,27 have again made open surgery a viable option for treating these complex aneurysms. This study describes the surgical strategy for the radical treatment of bilateral VADAs using bypass surgery.…”

New surgical treatment for vertebral artery pseudoaneurysm at the boundary between the V2 and V3 segments

“…И наконец, K. Hisashi и соавт. [12] в 2013 г. описали три клинических случая с аневризмами интракраниального отдела V 4 сегмента у пациентов, которым выполнялись после резекции аневризм в 2 случаях позвоночно-позвоночное шунтирование из V 3 в V 4 сегмент ПА и в 1 случае -наружносонно-по-звоночное шунтирование с использованием в каче-стве шунта лучевой или затылочной артерии.…”

EC‐IC bypass for cerebral revascularization following skull base tumor resection: Current practices and innovations

“…Since the first report of its successful use in cerebral revascularization in 1970, extracranial‐to‐intracranial (EC‐IC) bypass surgery has become an important part of the treatment of complex pathologies of the head and neck . Current indications for EC‐IC bypass include complex extracranial and intracranial aneurysms, Moyamoya disease, medically refractory occlusive neurological diseases, and the focus of this systematic review – skull base tumors . With each indication and variance in patient anatomy, a wide range of techniques and graft choices have been developed.…”

“…SVG and recipient vessel size mismatch can also be an issue as its diameter can be up to 4.0 ± 0.6 mm with a flow rate of approximately 70‐140 mL/min . Alternative donor vessels that have been reported include the superficial temporal vein, the epigastric artery, the thoracodorsal artery, the superior thyroid artery, the anterior and posterior tibial arteries, and the descending branch of the lateral circumflex femoral artery . The choice of which bypass option to utilize usually depends on factors such as the size of the recipient vessel, the desired amount of blood flow, the size and availability of donor vessels, the nature of the operation (emergent or elective) as well as the anatomy of the revascularization site …”
