Fig. 2From: Hematoma cavity separation and neomembrane thickness are potential triggers of recurrence of chronic subdural hematomaPreoperative CT scan, intraoperative images and postoperative CT scan on one of the patients without completely liquefied hematoma and hematoma cavity separation who underwent craniotomy. A preoperative CT image: Red arrow = None liquefied hematoma; Green arrow = thickened membranes connecting/separating the dura and the thickened arachnoid/pia matters. B, C Intraoperative images showing neomembrane, hematoma cavity separation as well as thickened membranes connecting/separating the dura and the thickened arachnoid/pia matters. B: Green arrows = thickened dura separators. C: Green arrows = thickened membrane connecting/separating the dura and the thickened arachnoid/pia matters, Red arrows = hematoma cavity separation, Black arrow = neomembrane and Blue arrow = dura. D Postoperative CT scan showing evaluation of the hematoma and separation of the thickened membranes connecting/separating the dura and the thickened arachnoid/pia mattersBack to article page
