Abstract

Ruptured middle cerebral artery (MCA) aneurysm with intrasylvian hematoma usually accompanied by progressive cerebral swelling with poorer outcomes. The authors present characteristics and importance of intrasylvian hematoma removal in the aneurysm surgery. From 2012 February to 2014 March, 24 aneurysm surgeries for ruptured MCA aneurysms with intrasylvian hematoma were performed in the authors' clinic. The patients were classified according to three groups. Group A included patients who underwent decompressive craniectomy within a few days after aneurysm surgery due to progressive cerebral swelling, group B included patients for whom decompression was not necessary, and group C included patients who showed severe cerebral swelling on admission and decompressive craniectomy and aneurysm surgery in one stage. The mean hematoma volume on admission was 28.56 mL, 24.96 mL, and 66.78 mL for groups A, B and C, respectively. Removal of a larger amount of hematoma was observed on postoperative computerized tomography scan in groups B and C (63.2% and 59.0%) compared with group A (33.4%). Although no statistical difference was found between group A and group B (p = 0.115), it tends to show the lesser amount of hematoma removed, the more...Continue Reading

Blood Clotting Disorders

Thrombophilia includes conditions with increased tendency for excessive blood clotting. Blood clotting occurs when the body has insufficient amounts of specialized proteins that make blood clot and stop bleeding. Here is the latest research on blood clotting disorders.

Aneurysm

Aneurysms are outward distensions or bulges that occurs in a weakened wall of blood vessels. Discover the latest research on aneurysms here.
