Microsurgical treatment of thrombosed middle cerebral artery (MCA) aneurysm is very complicated, especially in recurrent cases. A 48-year-old man presented with a recurrent thrombosed right MCA aneurysm. We performed MCA-to-MCA bypass using a superficial temporal artery (STA) interposition graft and proximal trapping. ⋯ We recommend this surgical technique in cases in which good STA backflow is guaranteed. In conclusion, revision surgery performed for a recurrent thrombosed MCA aneurysm with an MCA-STA interposition graft-MCA bypass with proximal trapping was successful. This technique is safe and effective for complex aneurysms with suboptimal condition of the STA, which could be due to reduced blood flow, previous surgery, or trauma.

Case Reports
Atlantoaxial dislocation associated with type-1 neurofibromatosis: case report and review of the literature.
Neurofibromatosis type 1 (NF-1) is an autosomal dominant genetic condition in which spinal deformities are commonly involved. However, atlantoaxial dislocation in NF-1 is extremely rare. A review of the English literature has identified only 10 cases in 8 reports. We report a rare case involving NF-1 associated with severe atlantoaxial dislocation. ⋯ Atlantoaxial dislocation is a rare complication in NF-1 patients. Surgical reduction combined with fusion is essential for a good outcome. Spine surgeons should also be knowledgeable about the possibility of significant hemorrhage before surgery.
