Cerebral Revascularization for Difficult Skull Base Tumors: A Contemporary Series of 18 Patients

Role of and Indications for Bypass Surgery After Carotid Occlusion Surgery Study (COSS)?

“…Bypass surgery is currently performed only in selected and rare cases, in which it is of importance to consider whether the benefit of radical resection plus arterial sacrifice and bypass improves survival with good quality of life and outweighs the risks. 3,[16][17][18] …”

“…Операция шунтирования в настоящее время осуществляется толь-ко в отдельных и редких случаях, в которых важно рассматривать вопрос о том, насколько радикальная резекция плюс удаление участка артерии и шунтирова-ние улучшают выживаемость с сохранением хорошего качества жизни и перевешивают риски [3,[16][17][18].…”

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

“…They can be generally classified as benign or malignant, with some overlap . The treatment and surgical resection of these tumors depends on the characteristics of the tumor and the experience of the surgical team . Tumors can vary in size, type, vascularity, and anatomical relation with respect to the brainstem, normal brain, and vascular structures.…”

“…However, patients with recurrence and previous radiotherapy often require vessel sacrifice due to the amount of scarring and risk of vascular injury. For a period of time, Sekhar’s group developed a more widespread approach to bypassing almost all tumors where resection may require arterial sacrifice or risk vascular injury or there was a concern for vascular insufficiency postoperatively . By adopting this philosophy, patients may unnecessarily undergo cerebral bypass .…”

Cerebral Bypass Surgery: Level of Evidence and Grade of Recommendation

“…: skull base tumors) are also a rare disease: the variety and heterogeneity of these lesions preclude RCTs. Only few case series, and expert opinion, are available (level of evidence 5, grade of recommendation D -see table 2) [7,12,22,41].…”
