随着无创性影像学技术的发展,未破裂脑动静脉畸形的检出率显著提高,对于这些患者应当采取保守治疗,还是积极的干预治疗,目前仍存在较大分歧。支持保守治疗者认为,未破裂脑动静脉畸形患者的自然出血风险相当低,而任何侵袭性治疗的预期治疗相关性并发症风险高;而主张积极治疗者认为,未破裂脑动静脉畸形自然出血的风险并不像想象的那样低,积极治疗并不会显著增高风险。目前这一问题仍需进行大样本随机对照临床试验来澄清。
With the development of noninvasive imaging techniques, the detection rate of unruptured cerebral arteriovenous malformations is significantly increased. For these patients should be conservative treatment, or active intervention, there are still major differences. In favor of conservative treatment, the risk of natural bleeding in patients with unruptured cerebral arteriovenous malformations is quite low, and the risk of any anticipated aggressive treatment-related complications of any invasive treatment is high, whereas advocates of active treatment believe that unruptured cerebral arteriovenous malformations naturally bleed Risk is not as low as expected, aggressive treatment does not significantly increase the risk. At present, this issue still needs to be clarified by large randomized controlled clinical trials.
