简介：AbstractPurpose:To explore the diagnosis and treatment of traumatic external carotid branch pseudoaneurysms.Methods:Eleven cases of traumatic external carotid artery branch pseudoaneurysms were admitted in our hospital. Digital subtraction angiography was performed in all patients. It revealed that the pseudoaneurysms originated from the internal maxillary artery in 5 cases, superficial temporal artery in 5 cases and occipital artery in 1 case. Five cases of internal maxillary artery pseudoaneurysms and 2 cases of superficial temporal artery pseudoaneurysms were treated by embolization; the other 3 cases were surgically resected.Results:Complete cessation of nasal bleeding was achieved in all the 5 pseudoaneurysms of internal maxillary artery after the endovascular therapies. Scalp bleeding stopped and scalp defect healed up in 2 patients with superficial temporal artery pseudoaneurysms treated by interventional therapy. All patients were followed up for 0.5-2.0 years without recurrence of nosebleed and scalp lump.Conclusion:For patients with repeated severe epistaxis after craniocerebral injury, digital subtraction angiography should be performed as soon as possible to confirm traumatic pseudoaneurysm. Endovascular therapy is an effective method for traumatic internal maxillary artery pseudoaneurysms. For patients with scalp injuries and pulsatile lumps, further examinations including digital subtraction angiography should be performed to confirm the diagnosis. Surgical treatment or endovascular therapy for scalp traumatic pseudoaneurysm is effective.

简介：我们现在的新奇向量排列和分支减小方法为小点颠倒算法骑车最小化执行的数字。新方法被使用挑选指令多重数据(SIMD)平行复杂数据浮点的实现快Fourier变换(快速傅里叶变换)。运作的钟周期的数字能被使用我们的分支减小方法被使用我们的向量排列方法并且在1.1被3.5的一个平均因素减少，与常规实现相比。MPC7448的实验(著名SIMD减少了指令集计算处理器)证明我们的最佳的小点颠倒算法一致地在复杂数组操作每元素比二个周期拿少数。
