Seven Bypasses: Tenets and Techniques for Revascularization is the third book in a trilogy of bravura, technical nuance, and strategy by master neurosurgeon Michael Lawton. Like his first two books on aneurysms and AVMs, Seven Bypasses provides unparalleled firsthand insights and guidance on complex pathologies in vascular neurosurgery. The fundamentals of microsurgical anastomosis and the craft of bypass surgery are explored in depth with clinical pearls in every chapter. Lawton eloquently reveals the art of cerebral revascularization in exquisite, metaphorical detail. The surgeon performing bypass surgery is like an architect envisioning and building a beautiful structure. A bypass is designed to fit the patient's unique anatomy; blueprints designate anastomotic sites, connections, and conduits; the anastomoses are constructed; and the bypass is brought to life with pulsations, flow, and reperfusion. The book highlights Lawton's aesthetic, which has evolved from the common STA-MCA bypasses to IC-IC bypasses and elaborate arterial reconstructions. Key HighlightsStepwise discussion of the three anastomoses that form the building blocks of all bypasses: end-to-side, side-to-side, and end-to-end anastomosesTen tenets delineate nuances of bypass: dexterity, preparing donors and recipients, establishing a working zone, temporary arterial occlusion, arteriotomy, suturing technique, tissue handling, knot tying, patency, and aneurysm occlusionStep-by-step guidance on the seven bypasses: EC-IC bypass, EC-IC interpositional bypass, arterial reimplantation, in-situ bypass, reanastomosis, IC-IC interpositional bypass, and combination bypassStrategies and algorithms for aneurysms organized by specific anatomical sites, including the MCA and the Sylvian cistern, ACA and the interhemispheric cistern, basilar artery and the basal cisterns, and PICA and the cisternweiterlesen
