(Figure 2a):the left middle cerebral artery occlusion beyond M2 segmen of the middle cerebral.(Figure 2b):micro-guide wire through the occluded segment division arrived in M3 segmen of the middle cerebral.
(Figure 2c):Micro-catheter through the occluded and reach the M3
segment,and M3senment was still vascular patency.(Figure 2d):the M2 segment beyond completely open after the role of micro-guide wire machine broken bolt and arterial injection of urokinase and papaverine.
Hemorrhagic stroke was the most serious complication to a vascular stent angioplasty,it was more common in patients with a high degree of stenosis.The responsibility vascular blood supply areas remain was in a low perfusion state,when other intracranial blood vessels were compensatory negative,the blood vessel was in poor self-regulatory function,after stening,the narrow vessles was improvement and influx of blood flow,resulting in a sudden increase in cerebral perfusion pressure caused by cerebral hemorrhage.This group did not happen cerebral hemorrhage complications,mainly because of effectively controlled blood pressure after the implant,controlling blood pressure normal range was 2/3 level of the patient's pre-operarion blood pressure.It can be effectively prevent a sudden increase in perfusion pressure caused by cerebral hemorrhage.
Our experience was that the clinical effect of endovascular treatment of carotid artery stenosis was good,it could effectively alleviate the clinical symptoms.To ensure the operation was successful and reduced complications,it should note the following:The operator must be gentle,careful and accurate,and used flexible of guide wire technology,and placed guide catheter in the first end of the proximal stenosis;As much as possible reduced in the narrow blood vessels at the various operations,including catheters,guide wires,cerebral protection device and so on,in the case of stent through the narrow vessle,we need not pre-expansion with balloon;Please use the distal protection device as much as possible in operation;monitor the patients'blood pressure,and treat timely to symptom;long-term use of anti-platelet therapy is the key to prevent restenosis ......
