Abstract: Introduction: Three-dimensional CT angiography (3DCTA) in diagnosis of cerebral aneurysms has replaced the invasive, but traditional catheter-based method of intra-arterial digital subtraction angiography (IADSA). This method has also been reported useful in the control of clipped aneurysms. Objective: To evaluate the utility of 3D-CTA in the control of clipped cerebral aneurysms after a subarachnoid hemorrhage (SAH) in a referral hospital. Patients and methods: We studied consecutive patients with SAH and clipped aneurisms, in a 24-month period, who had pre- and post-clipping 3D-CTA, as well as information on the clinical condition at hospital arrival, aneurysms localization and other features. The failure or success of aneurismal clipping was determined by 3D-CTA review by a radiologist blinded to the surgical procedure, and the intervention description by the neurosurgical team. Results: Twenty-eight patients were eligible for the present analysis; 16 (57%) women, mean age 50.5 years (range: 22-78 years). There were 32 aneurysms among the 28 patients (86% cases of solitaire and 14% with multiple aneurysms). In all, 97% were localized at the anterior circulation and 3% in the vertebro-basilar system. In only one (3%) patient failure of clipping was detected, which perfectly correlated with the neurosurgical team description. Conclusions: 3D-CTA is useful in the control of clipped cerebral aneurysms, with the advantage that it is a non-invasive method.

However, even today, there is a lack of formal and detailed analysis about the analog model in the literature. An accurate model of this device is very important for designing high performance analog cells. In this document a strategy for modeling the floating gate transistor operating in the weak inversion region based in the adaptation of the EKV model is proposed. The basis for developing a complete theory which allows the modeling of this device model is introduced. This type of modeling can be very useful for high performance analog integrated circuits designers where the transistor concerned here is strongly recommended. Further, this modeling process is also useful for the development of new computational tools for analog circuits simulation. " 2013 IEEE.
