Methods During the operation under barbiturate anesthesia, the proximal end of the feeding arteries were ligated at first, and 0.5 ml isobutyl 12 cyanoacrylate (IBCA) with 0.5 ml 5% glucose was injected into the vessels towards the AVM, then the malformed vessels were resected totally. Postoperative digital subtraction angiography of the four vessels was performed in all patients. Results 50 patients with giant AVM survived after operation, only 6 (12.0%) had transient neurological dysfunction and 44 (88.0%) recovered after a follow up of 6-36 months. No patient suffered from normal perfusion pressure breakthrough (NPPB). Conclusions The embolization could block the arteriovenous shunts sufficiently to decrease the blood flow away from the normal areas of the brain so as to prevent the incidence of intra and postoperative rebleeding, especially in NPPB. Therefore, the combination of intraoperative embolization with surgical resection is an effective strategy in the treatment of giant cerebral AVMs, which make it operable for those used to be regarded as inoperable cases.展开更多

The clinical features of CCSDH are very similar to those of noncalcified CSDH and include headache,decreased alertness,weakness,numbness,gait disturbance,seizures,memory impairment,confusion,and unconsciousness. All symptomatic CCSDH should be treated surgically. Majority of these patients recover well following surgery. In this report,we present the case of a patient with CCSDH who developed severe cerebral edema following its removal,necessitating decompressive craniectomy. Although there were no abnormal findings in laboratory blood tests,and no signs of brain herniation or epilepsy was found the following day after surgery,the patient's family refused all treatment and a post-operative brain computed tomography(CT) scan. The patient was discharged and died at home. Cerebral hematoma and normal perfusion pressure breakthrough(NPPB) may cause severe cerebral edema following the total removal of a CCSDH.展开更多
