以蛛网膜下腔出血起病的颅内多发动脉瘤的诊治

Diagnosis and treatment for multiple intracranial aneurysms presenting with subarachnoid hemorrhage

随着脑血管成像技术的广泛应用及不断提高,动脉瘤性蛛网膜下腔出血患者中多发动脉瘤检出率越来越高。研究表明既往有蛛网膜下腔出血病史患者的未破裂动脉瘤破裂风险要高于无蛛网膜下腔出血病史者,对于发生动脉瘤破裂的多发动脉瘤患者除明确责任动脉瘤并首先处理外,其未破裂动脉瘤也应尽量检出并积极治疗,因此多发动脉瘤的诊断和治疗均要比单发动脉瘤复杂。

With the wider availability and continuous advances of imaging techniques, the increasing numbers of multiple intracranial aneurysms are detected in patients with aneurysmal subarachnoid hemorrhage. Studies have shown that unruptured aneurysms in patients with previous subarachnoid hemorrhage have higher rupture risk than those without previous subarachnoid hemorrhage. For patients with multiple intracranial aneurysms presenting with subarachnoid hemorrhage, in addition to the ruptured aneurysms are identified and dealt with first, the unruptured aneurysms should be detected and treated aggressively. Therefore, the diagnosis and treatment of multiple intracranial aneurysms are more difficult than those of single ones.
