The Fate of Unruptured Intracranial Vertebrobasilar Dissecting Aneurysm with Brain Stem Compression According to Different Treatment Modalities

摘要: BACKGROUND AND PURPOSE: Unruptured intracranial vertebrobasilar dissecting aneurysms with brain stem compression are difficult to treat. In the present study, clinical and radiologic outcomes of unruptured based on different treatment modalities were evaluated. MATERIALS METHODS: This study included 28 patients treated from January 2009 December 2017. Treatment methods observation (n = 6), stent-assisted coil embolization 9), parent artery occlusion flow diversion 7). The data baseline characteristics, change aneurysm size, retreatment rate, stroke occurrence, alteration mRS score obtained retrospective chart review. RESULTS: initial size was largest in group (22.5 ± 7.7 mm), followed by (20.3 8.4 (11.7 2.2 (17.8 5.5 mm; P .01) groups. reduction rate highest (26.7 32.1%), (14.1% 28.7%), (−17.9 30.3%), (−31.5 30.8%; .007) Additional needed (4/6, 66.7%) (3/9, 33.3%; .017) Improvement follow-up observed (6/7, 85.7%) groups but not A worsened most common 66.7%), 33.3%), (2/6, (0/7, 0%) CONCLUSIONS: When treating compression, should be considered reduce improve score.
