At surgery, 8 cases (47%) were localized and classified as Shamblin class I, 4 cases (23.5%) as class II, and 5 cases (29.4%) as class III. Four patients had postoperative stroke (23.5%), with Shamblin classification related to the incidence of stroke (<jats:italic>P<\/jats:italic> = 0.041). In contrast, neither tumor size (<jats:italic>P<\/jats:italic> = 0.412) nor heparin injection before internal carotid artery (ICA) manipulation (<jats:italic>P<\/jats:italic> = 0.538) was associated with stroke. Although preoperative embolization of the tumor feeder did not significantly reduce the stroke rate (<jats:italic>P<\/jats:italic> = 0.579), early external carotid artery (ECA) division in patients with class II and III tumors was effective (<jats:italic>P<\/jats:italic> = 0.008). Internal carotid artery (ICA) manipulation, including reconstruction, ligation, and repair of injury, significantly increased the incidence of stroke (<jats:italic>P<\/jats:italic> = 0.029), as did ICA ligation without reconstruction (<jats:italic>P<\/jats:italic> = 0.044).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Internal carotid artery manipulation, including reconstruction, ligation, and repair of injury, significantly increased the incidence of stroke. For uncomplicated CBT resection, careful preoperative planning, especially for patients with class II and III tumors, is mandatory to avoid inadvertent ICA manipulation necessitated by bleeding.
