A2 segment of anterior cerebral artery microsurgical treatment of aneurysms (14 cases)
Wing Point Way by people with full anatomical brain pool , the release of cerebrospinal fluid , removal of part of the straight back track along the A1 to A2, A2 aneurysm clipped simultaneously , or combined anterior circulation aneurysms, can avoid the narrow interhemispheric space approach Shortcomings, and it is beneficial for wear artery reservations. The choice of the surgical side ,[link widoczny dla zalogowanych], according to habit and aneurysm surgeon toward the top , a reasonable choice 【 . Select the group of people way before the slit 10 cases ( 2 cases left , right n =  , wing point of the footpath in 2 cases ( 1 with both clipping the left middle cerebral artery aneurysm ), no intraoperative rupture of aneurysm No death , results were satisfactory. ③ surgical skills : A longitudinal approach , the first sinus return for a small branch bridging veins . If you block the surgical field . Electrocoagulation in the cortex after the cut side : When you need care when their bulky . Can be dissected along its direction of separation of cortex to increase the exposure space, while reducing venous infarction, or recurrent bleeding t4]. Slender anterior cerebral artery , should use the appropriate length of aneurysm clips, not too long, we often choose Mini folder,[link widoczny dla zalogowanych], * 121 * small straight or a little curved clip ,[link widoczny dla zalogowanych], clip to reduce the tumor blood vessels long false aneurysm caused by folder. In addition, when due to reset over the brain aneurysm clip , causing artery distortion,[link widoczny dla zalogowanych], ischemia. Therefore, intraoperative aneurysm clip in a small amount of gelatin sponge packing around the appropriate support to minimize the rotation of aneurysm clip . Poor exposure of the aneurysm neck , incomplete or incorrect clipping folder suspected peripheral artery branch arteries can be supplemented by small endoscopic observation. ④ After treatment: ischemic injury anterior cerebral artery aneurysms are the most common complication after surgery ,[link widoczny dla zalogowanych], the mortality reported in the literature about 5% ~ 50% t5]. When this group of patients in the conventional craniotomy mannitol dehydration, brain surgery to reduce traction and vascular stimulation : aneurysm after the plot as possible clear the brain pool of blood , after repeated washing with warm saline irrigation brainwashing papaverine Pool ; after conventional treatment of calcium antagonist and 3H . 1 case in this group see the aneurysm neck width and the line part of parent artery occlusion . Postoperative side paraparesis ; the remaining patients were successfully clipped aneurysm neck . Postoperative recovery was good.
