海绵窦动静脉瘘是目前难治的脑血管疾病之一。患者往往眼球突出,伴有搏动,比较痛苦。过去的手术治疗方法,并不完善。我院神经外科试用直流电电凝法为两例患者作治疗,保留了原来必须结扎的颈内动脉,获得成功。直流电电凝法的原理是:红细胞、白细胞和纤维蛋白在正常酸碱度的血液中呈负电,通入直流电时即移向正极。如血液中放入带有正电的金属时,这种移动和吸附作用更为明显,可使血液凝结。根 Cavernous sinus arteriovenous fistula is one of the most refractory cerebrovascular diseases. Patients are often prominent eye, accompanied by beating, more painful. Surgical treatment of the past, not perfect. Neurosurgical trial of our hospital DC coagulation method for the treatment of two patients, retained the original internal carotid artery must be ligated, to be successful. The principle of DC coagulation method is: red blood cells, white blood cells and fibrin in the normal pH of the blood was negative, when the direct current into the positive. Such as the blood into the positively charged metal, the movement and adsorption more obvious, can make blood coagulation. root
