Decompressive craniectomy for stroke

  Introduction Basics: The role of decompressive craniectomy for stroke is controversial and the postoperative morbidity and mortality is significant. Large ischemic strokes can exert significant mass effect through swelling that normally occurs 24-72 hours from symptom onset in about 10% of patients. Ischemic strokes are not felt to produce clinically significant global elevation in ICPd but causes delayed deterioration …
